Composite Actions: Support Env Flow by ethanchewy · Pull Request #557 · actions/runner

ethanchewy · 2020-06-18T20:03:03Z

This is branched off of my previous PR #549

In this PR, I build in support for environment variables for a Composite Action and its steps as described in the ADR: https://github.com/actions/runner/blob/users/ethanchewy/compositeADR/docs/adrs/0549-composite-run-steps.md#environment

action.yml

runs:
    using: "composite"
    steps: 
      - run: echo Composite Action Server ${{ env.SERVER }}
      - run: echo Server changed to ${{ env.SERVER }}

workflow.yml

jobs:
  build:
    runs-on: self-hosted
    steps:
    - uses: actions/checkout@v2
    - id: composite1
      uses: ethanchewy/test-composite@env
      with:
        your_name: "Octocat"
      env:
        NAME3: testasdfasdfads
    - name: test outputs
      run: echo Server: ${{ env.SERVER }}

Demo: https://github.com/ethanchewy/testing-actions/runs/846467581?check_suite_focus=true

This is an experimental feature that can only be turned on via turning the feature flag on:
export TESTING_COMPOSITE_ACTIONS_ALPHA=1
./run.sh

src/Runner.Worker/action_yaml.json

            "mapping": {
                "properties": {
                    "using": "non-empty-string",
+                    "env": "runs-env",


Since, container-runs-env's structure is used by both composite actions and container actions, I decided to change the name so that both types of runs can use it.

Moreover, to support this change, I made sure to look at all files that contained container-runs-env and replace it with `run-env'

~~TODO: We need to add context so that env variables are evaluated when Runner jobs are printed (ex: Run echo Name3 changed to $NAME3 should instead be Run echo Name3 changed to fdasdfadsf~~

Nevermind, in both the composite action and workflow steps, the environment contexts are evaluated correctly: https://github.com/ethanchewy/testing-actions/runs/795652488?check_suite_focus=true

Remove for now since we don't need to supprot outputs in action

+            var compositeEnvData = manifestManager.EvaluateCompositeActionEnvironment(ExecutionContext, Data.Environment, extraExpressionValues);


Remove Data.Environment

ethanchewy · 2020-07-07T16:38:46Z

Removed all of my code that supported the env token in the composite action.

Updated Description above to reflect this.

ericsciple · 2020-07-07T20:34:18Z

lets make sure to test this:

steps:
  - uses: myorg/mycompositeaction@v1
     env: 
      foo: this is foo
  - run: printenv|sort        # prints baz


# my composite action
steps:
  - env: 
      bar: this is bar 
    run: | 
      echo '::set-env name=baz::this is baz'
      printenv|sort        # prints foo and bar

ericsciple · 2020-07-07T21:12:47Z

let's go with this behavior

steps:
  - run: echo ::set-env name=foo::this is foo 1
  - uses: myorg/mycompositeaction@v1
     env: 
      foo: this is foo 2

# my composite action
steps:
  - printenv|sort           # should get foo 2 (more specific)
  - run: echo ::set-env name=foo::this is foo 3
  - printenv|sort           # will get foo 2 also... let's mark it as a bug and figure out how to solve w/ nested step runner

ethanchewy · 2020-07-07T22:16:00Z

First test works as intended:
https://github.com/ethanchewy/testing-actions/runs/847543901?check_suite_focus=true

Second test works as intended as well:
https://github.com/ethanchewy/testing-actions/runs/847558293?check_suite_focus=true

As discussed with Ting and Eric, we will most likely have to refactor this in the future. See above comments by Eric for reference.

Pushing changes soon.

we'll figure out how to simplify w/ nested composite steps runner (when we solve timeout)
