act-and-github

Environment variable use in github workflows and act.

Run with act -e <( echo '{"push": { "ref": "refs/tags/prerelease" } }' ) locally.

Result with github

Note the pattern which tests did run and which didn't run:

Result with act

[CI/build]   ✅  Success - Dump Environment
[CI/build] ⭐  Run Test1
[CI/build]   🐳  docker exec cmd=[bash --noprofile --norc -e -o pipefail /Volumes/Source/srcM/act-and-github/workflow/1] user=

[CI/build]   ✅  Success - Test1

[CI/build]   ✅  Success - Test2

[CI/build]   ✅  Success - Test3.1

The pattern of tests that ran and that did not run, is the same.

Define environment variable in container

Create a docker container that defines ENV2.

act/Dockerfile:

FROM catthehacker/ubuntu:act-20.04

ENV ENV2=true

docker build -t act-and-github:act ./act

Run act with runner image:

act -P ubuntu-latest=act-and-github:act -e <( echo '{"push": { "ref": "refs/tags/prerelease" } }' )

Check env output to see that ENV2 is defined now:

Still same output though as if ENV2 was undefined.
