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.
* 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.
Instead of needing you to first select the current stack to use any of
these commands, allow passing `-s <stack-name>` or `--stack
<stack-name>` to say what stack you want to operate on.
These commands still require a `Pulumi.yaml` file to be present, which
is not ideal, but would require a larger refactoring to fix. That
refactoring will happen as part of #1556.
Fixes#1370
This change supports displaying manifest information for a stack and
changes the way we handle Snapshots in our backend.
Previously, every call to GetStack would synthesize a Snapshot by
taking the set of resources returned from the
`/api/stacks/<owner>/<name>` endpoint, combined with an empty
manfiest (since the service was not returning the manifest).
This wasn't great for two reasons:
1. We didn't have manifest information, so we couldn't display any of
its information (most important the last updated time).
2. This strategy required that the service return all the resources
for a stack anytime GetStack was called. While the CLI did not
often need this detailed information the fact that we forced the
Service to produce it (which in the case of stack managed PPC would
require the service to talk to yet another service) creates a bunch
of work that we end up ignoring.
I've refactored the code such that `backend.Stack`'s `Snapshot()` method
now lazily requests the information from the service such that we can
construct a `Snapshot()` on demand and only pay the cost when we
actually need it.
I think making more of this stuff lazy is the long term direction we
want to follow.
Unfortunately, right now, it means in cases where we do need this data
we end up fetching it twice. The service does it once when we call
GetStack and then we do it again when we actually need to get at the
Snapshot. However, once we land this change, we can update the
service to no longer return resources on the apistack.Stack type. The
CLI no longer needs this property. We'll likely want to continue in a
direction where `apistack.Stack` can be created quickly by the
service (without expensive database queries or fetching remote
resources) and just add additional endpoints that let us get at the
specific information we want in the specific cases when we want it
instead of forcing us to return a bunch of data that we often ignore.
Fixespulumi/pulumi-service#371
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.
Previously, we would just use normal go formatting when displaying
output values. This was fine for simple values like strings and ints,
but for arrays or objects, you'd end up with values that looked a
little stange.
We now run the objects through json.Marshal first, to get nicer string
values for more complex objects. However, when the top level value is
a single string, we elide the quotes. This is not true JSON, but it
displays much nicer.
When we add something like `--format=json` (see pulumi#496) it will
provide a way to treat output unfiormly as JSON.
Fixes#736
This will allow us to remove a lot of current boilerplate in individual tests, and move it into the test harness.
Note that this will require updating users of the integration test framework. By moving to a property bag of inputs, we should avoid needing future breaking changes to this API though.
This change adds a `pulumi stack output` command. When passed no
arguments, it prints all stack output properties, in exactly the
same format as `pulumi stack` does (just without all the other stuff).
More importantly, if you pass a specific output property, a la
`pulumi stack output clusterARN`, just that property will be printed,
in a scriptable-friendly manner. This will help us automate wiring
multiple layers of stacks together during deployments.
This fixespulumi/pulumi#659.
