Github Concurrency Group

[rlinstorres]

Hi, I would like to know if it is possible to configure a concurrency workflow run checking for another workflow, for example:

Let's assume I have two workflows: concurrency-1.yml and concurrency-2.yml and concurrency-1 should only run when itself is not running and concurrency-2 is not running.

I tried the options below, but none of them worked as I need:

name: concurrency-1

on:
  push:
    branches:
      - master
  workflow_dispatch:

concurrency:
#group: ${{ github.workflow }}-${{ github.ref }} || concurrency-2-${{ github.ref }}
#group: ${{ github.workflow }} || concurrency-2
#group: ${{ github.workflow || startsWith(github.workflow, 'concurrency-2') }}

jobs:

I didn't find anything related to it in https://docs.github.com/en/actions/using-jobs/using-concurrency.

Does anyone know if it is possible?
Thank you!

What concurrency group do you set in the other workflow?

While the docs state that you use an arbitrary expression, I believe that it always needs to return a string to define the concurrency group and using a logical or (||) only lets you define a fallback value, like shown in the docs example. Therefore, I think what you need to do is to set the same string in both of the workflows. If you want the second workflow to run concurrently to the first workflow, however, then I'm not sure how you would set the concurrency group using some expression.

Hi @Simran-B, let me share the workflows trying to clarify them, to be honest, I am not sure if I am trying something impossible 😄
Note: I also tried to configure a concurrency group only checking for the second workflow and it doesn't work, my example, below:

name: concurrency-1

on:
  push:
    branches:
      - master
  workflow_dispatch:

concurrency:
  group: concurrency-2
#  group: concurrency-2 || concurrency-1 || ${{ github.workflow }}-${{ github.ref }}
#  group: ${{ github.ref }} || concurrency-2
#  group: ${{ github.workflow || startsWith(github.workflow, 'concurrency-2') }}

and

name: concurrency-2

on:
  workflow_run:
    workflows: [concurrency-1]
    types: [completed]
    branches:
      - master
  workflow_dispatch:

concurrency:
  group: ${{ github.workflow }}-${{ github.ref }}
