Luke Hoban 25206c5ea8 Add an experimental pulumi watch command (#3391)
Adds a new experimental `pulumi watch` CLI command which can be used for inner loop development on a Pulumi stack.  This command is only available currently via `PULUMI_EXPERIMENTAL=true` while in active development.

The `watch` command does the following:
1. Watches the workspace (the tree rooted at the `Pulumi.yaml` file) for changes
2. Triggers an `update` to the stack whenever there is a change
3. Streams output containing summaries of key update events as well as logs from any resources under management into a combined CLI output

Part of https://github.com/pulumi/pulumi/issues/3448.

The PULUMI_EXPERIMENTAL flag also makes`query` and `policy` available.

Standardize on Stack for backend methods. (#3336)
The current pattern of using backend.Stack values in the CLI but
accepting backend.StackReference values in backend methods leads to
frequent transitions between these types. In the case of the HTTP
backend, the transition from a StackReference to a Stack requires an API
call. These changes refactor the backend.Backend API such that most of
its methods accept backend.Stack values in place of
backend.StackReference values, which avoids these transitions.

This removes two calls to the getStack API on the startup path of a
`pulumi preview`.

Alex Clemmer c93a860574 Add PolicyPack abstraction with Publish verb
This commit will implement the core business logic of `pulumi policy
publish` -- code to boot an analyzer, ask it for metadata about the
policies it contains, pack the code, and transmit all of this to the
Pulumi service.

Matt Ellis 917f3738c5 Add --server to pulumi plugin install
Previously, when the CLI wanted to install a plugin, it used a special
method, `DownloadPlugin` on the `httpstate` backend to actually fetch
the tarball that had the plugin. The reason for this is largely tied
to history, at one point during a closed beta, we required presenting
an API key to download plugins (as a way to enforce folks outside the
beta could not download them) and because of that it was natural to
bake that functionality into the part of the code that interfaced with
the rest of the API from the Pulumi Service.

The downside here is that it means we need to host all the plugins on
`api.pulumi.com` which prevents community folks from being able to
easily write resource providers, since they have to manually manage
the process of downloading a provider to a machine and getting it on
the `$PATH` or putting it in the plugin cache.

To make this easier, we add a `--server` argument you can pass to
`pulumi plugin install` to control the URL that it attempts to fetch
the tarball from. We still have perscriptive guidence on how the
tarball must be
named (`pulumi-[<type>]-[<provider-name>]-vX.Y.Z.tar.gz`) but the base
URL can now be configured.

Folks publishing packages can use install scripts to run `pulumi
plugin install` passing a custom `--server` argument, if needed.

There are two improvements we can make to provide a nicer end to end
story here:

- We can augment the GetRequiredPlugins method on the language
  provider to also return information about an optional server to use
  when downloading the provider.

- We can pass information about a server to download plugins from as
  part of a resource registration or creation of a first class
  provider.

These help out in cases where for one reason or another where `pulumi
plugin install` doesn't get run before an update takes place and would
allow us to either do the right thing ahead of time or provide better
error messages with the correct `--server` argument. But, for now,
this unblocks a majority of the cases we care about and provides a
path forward for folks that want to develop and host their own
resource providers.

Matt Ellis 6278c1c8d9 Do not depend on backend package from client package
The next change is going to do some code motion that would create some
circular imports if we did not do this. There was nothing that
required the members we were moving be in the backend package, so it
was easy enough to pull them out.

Matt Ellis e7e934a59a Push initialization of SecretsManager out of the backend
When preforming an update, require that a secrets manager is passed in
as part of the `backend.UpdateOperation` bag and use it.  The CLI now
passes this in (it still uses the default base64 secrets manager, so
this is just code motion into a high layer, since the CLI will be the
one to choose what secrets manager to use based on project settings).
2019-05-10 17:07:52 -07:00
Matt Ellis 67bb134c28 Don't return serialized outputs from stack.GetRooStacktResource
Half of the call sites didn't care about these values and with the
secrets work the ergonmics of calling this method when it has to
return serialized ouputs isn't great. Move the serialization for this
into the CLI itself, as it was the only place that cared to do
this (so it could display things to end users).
2019-05-10 17:07:52 -07:00
Matt Ellis 10792c417f Remove backend.GetStackCrypter
As part of the pluggable secrets work, the crypter's used for secrets
are no longer tied to a backend. To enforce this, we remove the
`backend.GetStackCrypter` function and then have the relevent logic to
construct one live inside the CLI itself.

Right now the CLI still uses the backend type to decide what Crypter
to build, but we'll change that shortly.

Matt Ellis 97902ee50b Refactor config loading out of the backend
We require configuration to preform updates (as well as previews,
destroys and refreshes). Because of how everything evolved, loading
this configuration (and finding the coresponding decrypter) was
implemented in both the file and http backends, which wasn't great.

Refactor things such that the CLI itself builds out this information
and passes it along to the backend to preform operations. This means
less code duplicated between backends and less places the backend
assume things about the existence of `Pulumi.yaml` files and in
general makes the interface more plesent to use for others uses.

Matt Ellis cc74ef8471 Encrypt secret values in deployments
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.

Alex Clemmer 2c7af058de Expose resource outputs through invoke
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.

Alex Clemmer da82638edd Add query primitives to state backend
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.

Matt Ellis a1bb16407d Add pulumi stack rename
`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 (#2560)
* 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.

Pat Gavlin bc08574136
Add an API for importing stack outputs (#2180)
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.

Default an update's message to the Git commit title (#2009)
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.

Fixes pulumi/pulumi#2008.

joeduffy 95e917441a Implement preview-then-update for local stacks
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...)

joeduffy bf51d7594a Refactor display logic out of pkg/backend/filestate
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.

joeduffy 126d31c9c2 Simplify logging into the local backend
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.

joeduffy cd5707f483 Clarify refresh text
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 fixes pulumi/pulumi#1551.

Initial support for passing URLs to new and up (#1727)
* 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.

Matt Ellis 6845f9ed20 Add pulumi config refresh to fetch most recent configuration
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.

Begin tracing Pulumi API calls. (#1330)
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.

joeduffy 7c7f6d3ed7 Bring back preview, swizzle some flags
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.

joeduffy 6ad785d5c4 Revise the way previews are controlled
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.

Plumb basic cancellation through the engine. (#1231)
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.

joeduffy b77403b4bb Implement a refresh command
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 ...
