When constructing a Deployment (which is a plaintext representation of
a Snapshot), ensure that we encrypt secret values. To do so, we
introduce a new type `secrets.Manager` which is able to encrypt and
decrypt values. In addition, it is able to reflect information about
itself that can be stored in the deployment such that we can
deserialize the deployment into a snapshot (decrypting the values in
the process) without external knowledge about how it was encrypted.
The ability to do this is import for allowing stack references to
work, since two stacks may not use the same manager (or they will use
the same type of manager, but have different state).
The state value is stored in plaintext in the deployment, so it **must
not** contain sensitive data.
A sample manager, which just base64 encodes and decodes strings is
provided, as it useful for testing. We will allow it to be varried
soon.
This command exposes a new resource `Invoke` operation,
`pulumi:pulumi:readStackResourceOutputs` which retrieves all resource
outputs for some user-specified stack, not including those deleted.
Fixes#2600.
Because `pulumi query` is not implemented with the update
infrastructure, it is important that we *not* do things like open an
update when the query program runs.
This commit will thus implement the "query" path in the state backend in
a completely parallel universe. Conceptually, this is much like the
update path, but with a conspicuous lack of any connection to the
backend service.
`pulumi stack rename` allows you to change the name of an existing
stack. This operation is non-distructive, however it is possible that
the next update will show additional changes to resources, if the
pulumi program uses the value of `getStack()` as part of a resource
name.
* Install missing plugins on startup
This commit addresses the problem of missing plugins by scanning the
snapshot and language host on startup for the list of required plugins
and, if there are any plugins that are required but not installed,
installs them. The mechanism by which plugins are installed is exactly
the same as 'pulumi plugin install'.
The installation of missing plugins is best-effort and, if it fails,
will not fail the update.
This commit addresses pulumi/pulumi-azure#200, where users using Pulumi
in CI often found themselves missing plugins.
* Add CHANGELOG
* Skip downloading plugins if no client provided
* Reduce excessive test output
* Update Gopkg.lock
* Update pkg/engine/destroy.go

* CR: make pluginSet a newtype
* CR: Assign loop induction var to local var
These changes add a new resource to the Pulumi SDK,
`pulumi.StackReference`, that represents a reference to another stack.
This resource has an output property, `outputs`, that contains the
complete set of outputs for the referenced stack. The Pulumi account
performing the deployment that creates a `StackReference` must have
access to the referenced stack or the call will fail.
This resource is implemented by a builtin provider managed by the engine.
This provider will be used for any custom resources and invokes inside
the `pulumi:pulumi` module. Currently this provider supports only the
`pulumi:pulumi:StackReference` resource.
Fixes#109.
There is a seldom-used capability in our CLI, the ability to pass
-m to specify an update message, which we will then show prominently.
At the same time, we already scrape some interesting information from
the Git repo from which an update is performed, like the SHA hash,
committer, and author information. We explicitly didn't want to scrape
the entire message just in case someone put sensitive info inside of it.
It seems safe -- indeed, appealing -- to use just the title portion
as the default update message when no other has been provided (the
majority case). We'll work on displaying it in a better way, but this
strengthens our GitOps/CI/CD story.
Fixespulumi/pulumi#2008.
* Have backend.ListStacks return a new StackSummary interface
* Update filestake backend to use new type
* Update httpstate backend to use new type
* Update commands to use new type
* lint
* Address PR feedback
* Lint
This change implements the same preview behavior we have for
cloud stacks, in pkg/backend/httpbe, for local stacks, in
pkg/backend/filebe. This mostly required just refactoring bits
and pieces so that we can share more of the code, although it
does still entail quite a bit of redundancy. In particular, the
apply functions for both backends are now so close to being
unified, but still require enough custom logic that it warrants
keeping them separate (for now...)
This simply refactors all the display logic out of the
pkg/backend/filestate package. This helps to gear us up to better unify
this logic between the filestate and httpstate backends.
Furthermore, this really ought to be in its own non-backend,
CLI-specific package, but I'm taking one step at a time here.
As part of making the local backend more prominent, this changes a few
aspects of how you use it:
* Simplify how you log into a specific cloud; rather than
`pulumi login --cloud-url <url>`, just say `pulumi login <url>`.
* Use a proper URL scheme to denote local backend usage. We have chosen
file://, since the REST API backend is of course always https://.
This means that you can say `pulumi login file://~` to use the local
backend, with state files stored in your home directory. Similarly,
we support `pulumi login file://.` for the current directory.
* Add a --local flag to the login command, to make local logins a
bit easier in the common case of using your home directory. Just say
`pulumi login --local` and it is sugar for `pulumi login file://~`.
* Print the URL for the backend after logging in; for the cloud,
this is just the user's stacks page, and for the local backend,
this is the path to the user's stacks directory on disk.
* Tidy up the documentation for login a bit to be clearer about this.
This is part of pulumi/pulumi#1818.
The wording for refresh doesn't accurately convey that the operations
aren't actually mutating your resources, but instead are simply changing
your checkpoint state. This change (hopefully) helps in two ways:
First, put text just before the prompt:
Do you want to perform this refresh?
No resources will be modified as part of this refresh; just your stack's state will be.
Second, alter the summary ever-so-slightly, from:
info: 2 changes performed:
~ 2 resources updated
3 resources unchanged
to:
info: 2 changes refreshed:
~ 2 resources updated
3 resources unchanged
This reads just slightly better, and removes any sense of panic I might
have otherwise had that my refresh just did something wrong.
As I was in here, since I had to pass UpdateKind information to new
places, I cleaned up the situation where we had three mostly-similar
enums (but which actually diverged) and several areas where we were
using untyped strings for this same information. Now there's just one.
This fixespulumi/pulumi#1551.
* Initial support for passing URLs to `new` and `up`
This PR adds initial support for `pulumi new` using Git under the covers
to manage Pulumi templates, providing the same experience as before.
You can now also optionally pass a URL to a Git repository, e.g.
`pulumi new [<url>]`, including subdirectories within the repository,
and arbitrary branches, tags, or commits.
The following commands result in the same behavior from the user's
perspective:
- `pulumi new javascript`
- `pulumi new https://github.com/pulumi/templates/templates/javascript`
- `pulumi new https://github.com/pulumi/templates/tree/master/templates/javascript`
- `pulumi new https://github.com/pulumi/templates/tree/HEAD/templates/javascript`
To specify an arbitrary branch, tag, or commit:
- `pulumi new https://github.com/pulumi/templates/tree/<branch>/templates/javascript`
- `pulumi new https://github.com/pulumi/templates/tree/<tag>/templates/javascript`
- `pulumi new https://github.com/pulumi/templates/tree/<commit>/templates/javascript`
Branches and tags can include '/' separators, and `pulumi` will still
find the right subdirectory.
URLs to Gists are also supported, e.g.:
`pulumi new https://gist.github.com/justinvp/6673959ceb9d2ac5a14c6d536cb871a6`
If the specified subdirectory in the repository does not contain a
`Pulumi.yaml`, it will look for subdirectories within containing
`Pulumi.yaml` files, and prompt the user to choose a template, along the
lines of how `pulumi new` behaves when no template is specified.
The following commands result in the CLI prompting to choose a template:
- `pulumi new`
- `pulumi new https://github.com/pulumi/templates/templates`
- `pulumi new https://github.com/pulumi/templates/tree/master/templates`
- `pulumi new https://github.com/pulumi/templates/tree/HEAD/templates`
Of course, arbitrary branches, tags, or commits can be specified as well:
- `pulumi new https://github.com/pulumi/templates/tree/<branch>/templates`
- `pulumi new https://github.com/pulumi/templates/tree/<tag>/templates`
- `pulumi new https://github.com/pulumi/templates/tree/<commit>/templates`
This PR also includes initial support for passing URLs to `pulumi up`,
providing a streamlined way to deploy installable cloud applications
with Pulumi, without having to manage source code locally before doing
a deployment.
For example, `pulumi up https://github.com/justinvp/aws` can be used to
deploy a sample AWS app. The stack can be updated with different
versions, e.g.
`pulumi up https://github.com/justinvp/aws/tree/v2 -s <stack-to-update>`
Config values can optionally be passed via command line flags, e.g.
`pulumi up https://github.com/justinvp/aws -c aws:region=us-west-2 -c foo:bar=blah`
Gists can also be used, e.g.
`pulumi up https://gist.github.com/justinvp/62fde0463f243fcb49f5a7222e51bc76`
* Fix panic when hitting ^C from "choose template" prompt
* Add description to templates
When running `pulumi new` without specifying a template, include the template description along with the name in the "choose template" display.
```
$ pulumi new
Please choose a template:
aws-go A minimal AWS Go program
aws-javascript A minimal AWS JavaScript program
aws-python A minimal AWS Python program
aws-typescript A minimal AWS TypeScript program
> go A minimal Go program
hello-aws-javascript A simple AWS serverless JavaScript program
javascript A minimal JavaScript program
python A minimal Python program
typescript A minimal TypeScript program
```
* React to changes to the pulumi/templates repo.
We restructured the `pulumi/templates` repo to have all the templates in the root instead of in a `templates` subdirectory, so make the change here to no longer look for templates in `templates`.
This also fixes an issue around using `Depth: 1` that I found while testing this. When a named template is used, we attempt to clone or pull from the `pulumi/templates` repo to `~/.pulumi/templates`. Having it go in this well-known directory allows us to maintain previous behavior around allowing offline use of templates. If we use `Depth: 1` for the initial clone, it will fail when attempting to pull when there are updates to the remote repository. Unfortunately, there's no built-in `--unshallow` support in `go-git` and setting a larger `Depth` doesn't appear to help. There may be a workaround, but for now, if we're cloning the pulumi templates directory to `~/.pulumi/templates`, we won't use `Depth: 1`. For template URLs, we will continue to use `Depth: 1` as we clone those to a temp directory (which gets deleted) that we'll never try to update.
* List available templates in help text
* Address PR Feedback
* Don't show "Installing dependencies" message for `up`
* Fix secrets handling
When prompting for config, if the existing stack value is a secret, keep it a secret and mask the prompt. If the template says it should be secret, make it a secret.
* Fix ${PROJECT} and ${DESCRIPTION} handling for `up`
Templates used with `up` should already have a filled-in project name and description, but if it's a `new`-style template, that has `${PROJECT}` and/or `${DESCRIPTION}`, be helpful and just replace these with better values.
* Fix stack handling
Add a bool `setCurrent` param to `requireStack` to control whether the current stack should be saved in workspace settings. For the `up <url>` case, we don't want to save. Also, split the `up` code into two separate functions: one for the `up <url>` case and another for the normal `up` case where you have workspace in your current directory. While we may be able to combine them back into a single function, right now it's a bit cleaner being separate, even with some small amount of duplication.
* Fix panic due to nil crypter
Lazily get the crypter only if needed inside `promptForConfig`.
* Embellish comment
* Harden isPreconfiguredEmptyStack check
Fix the code to check to make sure the URL specified on the command line matches the URL stored in the `pulumi:template` config value, and that the rest of the config from the stack satisfies the config requirements of the template.
These changes add support for adding a tracing header to API requests
made to the Pulumi service. Setting the `PULUMI_TRACING_HEADER`
environment variable or enabling debug commands and passing the
`--tracing-header` will change the value sent in this header. Setting
this value to `1` will request that the service enable distributed
tracing for all requests made by a particular CLI invocation.
The newly added `pulumi config refresh` updates your local copy of the
Pulumi.<stack-name>.yaml file to have the same configuration as the
most recent deployment in the cloud.
This can be used in a varirty of ways. One place we plan to use it is
in automation to clean up "leaked" stacks we have in CI. With the
changes you'll now be able to do the following:
```
$ cd $(mktemp -d)
$ echo -e "name: who-cares\nruntime: nodejs" > Pulumi.yaml
$ pulumi stack select <leaked-stack-name>
$ pulumi config refresh -f
$ pulumi destroy --force
```
Having a simpler gesture for the above is something we'll want to do
long term (we should be able to support `pulumi destory <stack-name>`
from a completely empty folder, today you need a Pulumi.yaml file
present, even if the contents don't matter).
But this gets us a little closer to where we want to be and introduces
a helpful primitive in the system.
Contributes to #814
These changes add support for injecting client tracing spans into HTTP
requests to the Pulumi API. The server can then rematerialize these span
references and attach its own spans for distributed tracing.
These changes enable tracing of Pulumi API calls.
The span with which to associate an API call is passed via a
`context.Context` parameter. This required plumbing a
`context.Context` parameter through a rather large number of APIs,
especially in the backend.
In general, all API calls are associated with a new root span that
exists for essentially the entire lifetime of an invocation of the
Pulumi CLI. There were a few places where the plumbing got a bit hairier
than I was willing to address with these changes; I've used
`context.Background()` in these instances. API calls that receive this
context will create new root spans, but will still be traced.
* Initialize a new stack as part of `pulumi new`
* Prompt for values with defaults preselected
* Install dependencies
* Prompt for default config values
This changes the CLI interface in a few ways:
* `pulumi preview` is back! The alternative of saying
`pulumi update --preview` just felt awkward, and it's a common
operation to want to perform. Let's just make it work.
* There are two flags consistent across all update commands,
`update`, `refresh`, and `destroy`:
- `--skip-preview` will skip the preview step. Note that this
does *not* skip the prompt to confirm that you'd like to proceed.
Indeed, it will still prompt, with a little warning text about
the fact that the preview has been skipped.
* `--yes` will auto-approve the updates.
This lands us in a simpler and more intuitive spot for common scenarios.
I found the flag --force to be a strange name for skipping a preview,
since that name is usually reserved for operations that might be harmful
and yet you're coercing a tool to do it anyway, knowing there's a chance
you're going to shoot yourself in the foot.
I also found that what I almost always want in the situation where
--force was being used is to actually just run a preview and have the
confirmation auto-accepted. Going straight to --force isn't the right
thing in a CI scenario, where you actually want to run a preview first,
just to ensure there aren't any issues, before doing the update.
In a sense, there are four options here:
1. Run a preview, ask for confirmation, then do an update (the default).
2. Run a preview, auto-accept, and then do an update (the CI scenario).
3. Just run a preview with neither a confirmation nor an update (dry run).
4. Just do an update, without performing a preview beforehand (rare).
This change enables all four workflows in our CLI.
Rather than have an explosion of flags, we have a single flag,
--preview, which can specify the mode that we're operating in. The
following are the values which correlate to the above four modes:
1. "": default (no --preview specified)
2. "auto": auto-accept preview confirmation
3. "only": only run a preview, don't confirm or update
4. "skip": skip the preview altogether
As part of this change, I redid a bit of how the preview modes
were specified. Rather than booleans, which had some illegal
combinations, this change introduces a new enum type. Furthermore,
because the engine is wholly ignorant of these flags -- and only the
backend understands them -- it was confusing to me that
engine.UpdateOptions stored this flag, especially given that all
interesting engine options _also_ accepted a dryRun boolean. As of
this change, the backend.PreviewBehavior controls the preview options.
hese changes plumb basic support for cancellation through the engine.
Two types of cancellation are supported for all engine operations:
- Cancellation, which waits for the operation to drive itself to a safe
point before the operation returns, and
- Termination, which does not wait for the operation to drive itself
to a safe opint for the operation returns.
When updating local or managed stacks, a single ^C triggers cancellation
of any running operation; a second ^C will trigger termination.
Fixes#513, #1077.
This change implements a `pulumi refresh` command. It operates a bit
like `pulumi update`, and friends, in that it supports `--preview` and
`--diff`, along with the usual flags, and will update your checkpoint.
It works through substitution of the deploy.Source abstraction, which
generates a sequence of resource registration events. This new
deploy.RefreshSource takes in a prior checkpoint and will walk it,
refreshing the state via the associated resource providers by invoking
Read for each resource encountered, and merging the resulting state with
the prior checkpoint, to yield a new resource.Goal state. This state is
then fed through the engine in the usual ways with a few minor caveats:
namely, although the engine must generate steps for the logical
operations (permitting us to get nice summaries, progress, and diffs),
it mustn't actually carry them out because the state being imported
already reflects reality (a deleted resource has *already* been deleted,
so of course the engine need not perform the deletion). The diffing
logic also needs to know how to treat the case of refresh slightly
differently, because we are going to be diffing outputs and not inputs.
Note that support for managed stacks is not yet complete, since that
requires updates to the service to support a refresh endpoint. That
will be coming soon ...
This change introduces support for using the cloud backend when
`pulumi init` has not been run. When this is the case, we use the new
identity model, where a stack is referenced by an owner and a stack
name only.
There are a few things going on here:
- We add a new `--owner` flag to `pulumi stack init` that lets you
control what account a stack is created in.
- When listing stacks, we show stacks owned by you and any
organizations you are a member of. So, for example, I can do:
* `pulumi stack init my-great-stack`
* `pulumi stack init --owner pulumi my-great-stack`
To create a stack owned by my user and one owned by my
organization. When `pulumi stack ls` is run, you'll see both
stacks (since they are part of the same project).
- When spelling a stack on the CLI, an owner can be optionally
specified by prefixing the stack name with an owner name. For
example `my-great-stack` means the stack `my-great-stack` owned by
the current logged in user, where-as `pulumi/my-great-stack` would
be the stack owned by the `pulumi` organization
- `--all` can be passed to `pulumi stack ls` to see *all* stacks you
have access to, not just stacks tied to the current project.
Long term, a stack name alone will not be sufficent to address a
stack. Introduce a new `backend.StackReference` interface that allows
each backend to give an opaque stack reference that can be used across
operations.
This change does three major things:
1. Removes the ability to be logged into multiple clouds at the same
time. Previously, we supported being logged into multiple clouds at
the same time and the CLI would fan out requests and join responses
when needed. In general, this was only useful for Pulumi employees
that wanted run against multiple copies of the service (say production
and staging) but overall was very confusing (for example in the old
world a stack with the same identity could appear twice (since it was
in two backends) which the CLI didn't handle very well).
2. Stops treating the "local" backend as a special thing, from the
point of view of the CLI. Previouly we'd always connect to the local
backend and merge that data with whatever was in clouds we were
connected to. We had gestures like `--local` in `pulumi stack init`
that meant "use the local mode". Instead, to use the local mode now
you run `pulumi login --cloud-url local://` and then you are logged in
the local backend. Since you can only ever be logged into a single
backend, we can remove the `--local` and `--remote` flags from `pulumi
stack init`, it just now requires you to be logged in and creates a
stack in whatever back end you were logged into. When logging into the
local backend, you are not prompted for an access key.
3. Prompt for login in places where you have to log in, if you are not
already logged in.
By using untyped deployment structures via `json.RawMessage`, we can
support round-tripping between old CLI clients and newer servers, without
dropping possibly-important information on the floor. I hadn't realized
this design goal with the original system, and after talking to @pgavlin,
I better realized the intent and that we want to preserve this.
The filenames we used to store history data locally only had second
level precision. On my machine, the test history test is able to run
multiple `pulumi update` commands in the same second, which causes a
newer history file to overwrite an older one.
This change moves to using a nanosecond precision timestamp when
writing config. In addition, the CLI was trying to sort the updates
that came back from the backend (instead of just trusting them to be
in newest first order, as we documented) so I removed that code as
well.
Despite our good progress moving towards having an apitype package,
where our exchange types live and can be shared among the engine and
our services, there were a few major types that were still duplciated.
Resource was the biggest example -- and indeed, the apitype varirant
was missing the new Dependencies property -- but there were others,
like Manfiest, PluginInfo, etc. These too had semi-random omissions.
This change merges all of these types into the apitype package. This
not only cleans up the redundancy and missing properties, but will
"force the issue" with respect to keeping them in sync and properly
versioning the information in a backwards compatible way.
The resource/stack package still exists as a simple marshaling layer
to and from the engine's core data types.
Finally, I've made the controversial change to share the actual
Deployment data structure at the apitype layer also. This will force
us to confront differences in that data structure similarly, and will
allow us to leverage the strong typing throughout to catch issues.
This change includes a handful of stack-related CLI formatting
improvements that I've been noodling on in the background for a while,
based on things that tend to trip up demos and the inner loop workflow.
This includes:
* If `pulumi stack select` is run by itself, use an interactive
CLI menu to let the user select an existing stack, or choose to
create a new one. This looks as follows
$ pulumi stack select
Please choose a stack, or choose to create a new one:
abcdef
babblabblabble
> currentlyselected
defcon
<create a new stack>
and is navigated in the usual way (key up, down, enter).
* If a stack name is passed that does not exist, prompt the user
to ask whether s/he wants to create one on-demand. This hooks
interesting moments in time, like `pulumi stack select foo`,
and cuts down on the need to run additional commands.
* If a current stack is required, but none is currently selected,
then pop the same interactive menu shown above to select one.
Depending on the command being run, we may or may not show the
option to create a new stack (e.g., that doesn't make much sense
when you're running `pulumi destroy`, but might when you're
running `pulumi stack`). This again lets you do with a single
command what would have otherwise entailed an error with multiple
commands to recover from it.
* If you run `pulumi stack init` without any additional arguments,
we interactively prompt for the stack name. Before, we would
error and you'd then need to run `pulumi stack init <name>`.
* Colorize some things nicely; for example, now all prompts will
by default become bright white.
This addresses pulumi/pulumi#446: what we used to call "package" is
now called "project". This has gotten more confusing over time, now
that we're doing real package management.
Also fixespulumi/pulumi#426, while in here.
The existing logic would flow colorization information into the
engine, so depending on the settings in the CLI, the engine may or may
not have emitted colorized events. This coupling is not great and we
want to start moving to a world where the presentation happens
exclusively at the CLI level.
With this change, the engine will always produce strings that have the
colorization formatting directives (i.e. the directives that
reconquest/loreley understands) and the CLI will apply
colorization (which could mean either running loreley to turn the
directives into ANSI escape codes, or drop them or retain them, for
debuging purposes).
Fixes#742
This PR adds a new `pulumi history` command, which prints the update history for a stack.
The local backend stores the update history in a JSON file on disk, next to the checkpoint file. The cloud backend simply provides the update metadata, and expects to receive all the data from a (NYI) `/history` REST endpoint.
`pkg/backend/updates.go` defines the data that is being persisted. The way the data is wired through the system is adding a new `backend.UpdateMetadata` parameter to a Stack/Backend's `Update` and `Destroy` methods.
I use `tests/integration/stack_outputs/` as the simple app for the related tests, hence the addition to the `.gitignore` and fixing the name in the `Pulumi.yaml`.
Fixes#636.
This PR surfaces the configuration options available to updates, previews, and destroys to the Pulumi Service. As part of this I refactored the options to unify them into a single `engine.UpdateOptions`, since they were all overlapping to various degrees.
With this PR we are adding several new flags to commands, e.g. `--summary` was not available on `pulumi destroy`.
There are also a few minor breaking changes.
- `pulumi destroy --preview` is now `pulumi destroy --dry-run` (to match the actual name of the field).
- The default behavior for "--color" is now `Always`. Previously it was `Always` or `Never` based on the value of a `--debug` flag. (You can specify `--color always` or `--color never` to get the exact behavior.)
Fixes#515, and cleans up the code making some other features slightly easier to add.
These changes refactor the engine's entrypoints--Deploy, Destroy, and
Preview--to be update-centric rather than stack-centric. Each of these
methods now takes a value of a new type, Update, that abstracts away the
vagaries of fetching and maintaining the update's state. This
refactoring also reinforces Pulumi.yaml as a CLI concept rather than an
engine concept; the CLI is now the only reader/writer of this format.
These changes will smooth the way for a few refactorings on the service
side that will aid in update isolation.
These changes add the ability to export a stack's latest deployment or
import a new deployment to a stack via the Pulumi CLI. These
capabilities are exposed by two new verbs under `stack`:
- export, which writes the current stack's latest deployment to stdout
- import, which reads a new deployment from stdin and applies it to the
current stack.
In the local case, this simply involves reading/writing the stack's
latest checkpoint file. In the cloud case, this involves hitting two new
endpoints on the service to perform the export or import.
Use the new {en,de}crypt endpoints in the Pulumi.com API to secure
secret config values. The ciphertext for a secret config value is bound
to the stack to which it applies and cannot be shared with other stacks
(e.g. by copy/pasting it around in Pulumi.yaml). All secrets will need
to be encrypted once per target stack.
This change implements some feedback from @ellismg.
* Make backend.Stack an interface and let backends implement it,
enabling dynamic type testing/casting to access information
specific to that backend. For instance, the cloud.Stack conveys
the cloud URL, org name, and PPC name, for each stack.
* Similarly expose specialized backend.Backend interfaces,
local.Backend and cloud.Backend, to convey specific information.
* Redo a bunch of the commands in terms of these.
* Keeping with this theme, turn the CreateStack options into an
opaque interface{}, and let the specific backends expose their
own structures with their own settings (like PPC name in cloud).
* Show both the org and PPC names in the cloud column printed in
the stack ls command, in addition to the Pulumi Cloud URL.
Unrelated, but useful:
* Special case the 401 HTTP response and make a friendly error,
to tell the developer they must use `pulumi login`. This is
better than tossing raw "401: Unauthorized" errors in their face.
* Change the "Updating stack '..' in the Pulumi Cloud" message to
use the correct action verb ("Previewing", "Destroying", etc).
This improves the overall cloud CLI experience workflow.
Now whether a stack is local or cloud is inherent to the stack
itself. If you interact with a cloud stack, we transparently talk
to the cloud; if you interact with a local stack, we just do the
right thing, and perform all operations locally. Aside from sometimes
seeing a cloud emoji pop-up ☁️, the experience is quite similar.
For example, to initialize a new cloud stack, simply:
$ pulumi login
Logging into Pulumi Cloud: https://pulumi.com/
Enter Pulumi access token: <enter your token>
$ pulumi stack init my-cloud-stack
Note that you may log into a specific cloud if you'd like. For
now, this is just for our own testing purposes, but someday when we
support custom clouds (e.g., Enterprise), you can just say:
$ pulumi login --cloud-url https://corp.acme.my-ppc.net:9873
The cloud is now the default. If you instead prefer a "fire and
forget" style of stack, you can skip the login and pass `--local`:
$ pulumi stack init my-faf-stack --local
If you are logged in and run `pulumi`, we tell you as much:
$ pulumi
Usage:
pulumi [command]
// as before...
Currently logged into the Pulumi Cloud ☁️https://pulumi.com/
And if you list your stacks, we tell you which one is local or not:
$ pulumi stack ls
NAME LAST UPDATE RESOURCE COUNT CLOUD URL
my-cloud-stack 2017-12-01 ... 3 https://pulumi.com/
my-faf-stack n/a 0 n/a
And `pulumi stack` by itself prints information like your cloud org,
PPC name, and so on, in addition to the usuals.
I shall write up more details and make sure to document these changes.
This change also fairly significantly refactors the layout of cloud
versus local logic, so that the cmd/ package is resonsible for CLI
things, and the new pkg/backend/ package is responsible for the
backends. The following is the overall resulting package architecture:
* The backend.Backend interface can be implemented to substitute
a new backend. This has operations to get and list stacks,
perform updates, and so on.
* The backend.Stack struct is a wrapper around a stack that has
or is being manipulated by a Backend. It resembles our existing
Stack notions in the engine, but carries additional metadata
about its source. Notably, it offers functions that allow
operations like updating and deleting on the Backend from which
it came.
* There is very little else in the pkg/backend/ package.
* A new package, pkg/backend/local/, encapsulates all local state
management for "fire and forget" scenarios. It simply implements
the above logic and contains anything specific to the local
experience.
* A peer package, pkg/backend/cloud/, encapsulates all logic
required for the cloud experience. This includes its subpackage
apitype/ which contains JSON schema descriptions required for
REST calls against the cloud backend. It also contains handy
functions to list which clouds we have authenticated with.
* A subpackage here, pkg/backend/state/, is not a provider at all.
Instead, it contains all of the state management functions that
are currently shared between local and cloud backends. This
includes configuration logic -- including encryption -- as well
as logic pertaining to which stacks are known to the workspace.
This addresses pulumi/pulumi#629 and pulumi/pulumi#494.
