Pulumi GitHub Actions

PLEASE NOTE: As of v3.1.0 of this GitHub Action, the end user no longer needs to install the Pulumi CLI as part of their workflow!

Pulumi's GitHub Actions deploy apps and infrastructure to your cloud of choice, using just your favorite language and GitHub. This includes previewing, validating, and collaborating on proposed deployments in the context of Pull Requests, and triggering deployments or promotions between different environments by merging or directly committing code.

Getting Started

name: Pulumi
on:
  push:
    branches:
      - master
jobs:
  up:
    name: Preview
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: pulumi/actions@v3
        with:
          command: preview
          stack-name: dev
        env:
          PULUMI_ACCESS_TOKEN: ${{ secrets.PULUMI_ACCESS_TOKEN }}

This will check out the existing directory and run pulumi preview.

Configuration

The action can be configured with the following arguments:

  • command (required) - The command to run as part of the action. Accepted values are up (update), refresh, destroy and preview.

  • stack-name (required) - The name of the stack that Pulumi will be operating on

  • work-dir (optional) - The location of your Pulumi files. Defaults to ./.

  • cloud-url - (optional) - the Pulumi backend to login to. This would be the equivalent of what would be passed to the pulumi login command. The action will login to the appropriate backend on your behalf provided it is configured with the correct access credentials for that backend.

  • comment-on-pr - (optional) If true, then the action will add the results of the Pulumi action to the PR

  • github-token - (optional) A GitHub token that has access levels to allow the Action to comment on a PR. Defaults to ${{ github.token }}

  • refresh - (optional) If true, stack is refreshed before running the command.

  • secrets-provider - (optional) The type of the provider that should be used to encrypt and decrypt secrets. Possible choices: default, passphrase, awskms, azurekeyvault, gcpkms, hashivault. e.g. gcpkms://projects//locations/us-west1/keyRings/acmecorpsec/cryptoKeys/payroll

Extra options

  • parallel - (optional) Allow P resource operations to run in parallel at once (1 for no parallelism). Defaults to unbounded.

  • message - (optional) Optional message to associate with the update operation

  • expect-no-changes - (optional) Return an error if any changes occur during this update

  • edit-pr-comment - (optional) Edit previous PR comment instead of posting new one. PLEASE NOTE that as of 3.2.0 of the Action, this now defaults to true. This is in an effort to reduce verbosity - if you want to have a comment per PR run, please ensure that you set this to false.

  • diff - (optional) Display operation as a rich diff showing the overall change

  • replace - (optional) Specify resources to replace. Multiple resources can be specified one per line

  • target - (optional) Specify a single resource URN to update. Other resources will not be updated. Multiple resources can be specified one per line

  • target-dependents - (optional) Allows updating of dependent targets discovered but not specified in target.

  • upsert - (optional) Allows the creation of the specified stack if it currently doesn't exist.
    PLEASE NOTE: This will create a Pulumi..yaml file that you will need to add back to source control as part of the action if you wish to perform any further tasks with that stack.

By default, this action will try to authenticate Pulumi with the Pulumi SaaS. If you have not specified a PULUMI_ACCESS_TOKEN then you will need to specify an alternative backend via the cloud-url argument.

Stack Outputs

Stack outputs are available when using this action. When creating a stack as follows:

package main

import (
	random "github.com/pulumi/pulumi-random/sdk/v2/go/random"
	"github.com/pulumi/pulumi/sdk/v2/go/pulumi"
)

func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		p, err := random.NewRandomPet(ctx, "my-user-name", &random.RandomPetArgs{})
		if err != nil {
			return err
		}
		ctx.Export("pet-name", p)
		return nil
	})
}

We can see that pet-name is an output. To get the value of this output in the action, we would use code similar to the following:

- uses: pulumi/actions@v3
  id: pulumi
  env:
    PULUMI_CONFIG_PASSPHRASE: ${{ secrets.PULUMI_CONFIG_PASSPHRASE }}
  with:
    command: up
    cloud-url: gs://my-bucket
    stack-name: dev
- run: echo "My pet name is ${{ steps.pulumi.outputs.pet-name }}"

the pet-name is available as a named output

Run echo "My pet name is pretty-finch"

Referencing Sensitive Values

We suggest that any sensitive environment variables be referenced using GitHub Secrets, and consuming them using the secrets attribute on your workflow's action.

Example workflows

The Pulumi GitHub action uses the Pulumi Automation API in order to coordinate the Pulumi operations. This means that there is no supporting functionality for npm or pip installs. This functionality should be deferred to the correct GitHub Marketplace actions that support it.

Migrating from GitHub Action v1 (and beyond)?

Here are some pointers when migrating from v1 to v2 of our GitHub Action.

  • The following inputs have changed from environment variables to action inputs:

    • PULUMI_ROOT is now work-dir
    • PULUMI_BACKEND_URL is now cloud-url
    • COMMENT_ON_PR is now comment-on-pr
    • GITHUB_TOKEN is now github-token

  • IS_PR_WORKFLOW is no longer a viable input. The action is able to understand if the workflow is a pull_request due to action type

  • The action now runs natively, so the action workflow needs to have the correct environment configured. There are sample workflows available. For examples, if you are running a NodeJS (for example) app then you need to ensure that your action has NodeJS available to it:

- uses: actions/setup-node@v1
with:
  node-version: 14.x
  • The action will no longer run npm ci | npm install | pip3 install | pipenv install. Please ensure that you are installing your dependencies before Pulumi commands are executed, e.g.:
- run: pip install -r requirements
  working-directory: infra
