delete-workflow-runs v2

The GitHub action to delete workflow runs in a repository. This action (written in JavaScript) wraps two Workflow Runs API:

• List repository workflows -- Lists the workflows in a repository.

• List workflow runs -- List all workflow runs for a workflow.

• Delete a workflow run -- Delete a specific workflow run.

The action will calculate the number of days that each workflow run has been retained so far, then use this number to compare with the number you specify for the input parameter "retain_days". If the retention days of the workflow run has reached (equal to or greater than) the specified number, the workflow run will be deleted.

What's new?

• Add the input parameter "delete_run_by_conclusion_pattern" - useful for skipped workflow runs.
• Add the input parameter "delete_workflow_by_state_pattern" and "dry_run".
• Add ability to filter workflows by workflow filename (in addition to the name)
• Add ability to filter workflows by state
• Add ability to perform a 'dry run' which logs the changes but doesn't perform the actual deletion.

Inputs

1. token

Required: YES

Default: ${{ github.token }}

The token used to authenticate.

• If the workflow runs are in the current repository where the action is running, using github.token is OK. More details, see the GITHUB_TOKEN.
• If the workflow runs are in another repository, you need to use a personal access token (PAT) that must have the repo scope. More details, see "Creating a personal access token".

2. repository

Required: YES

Default: ${{ github.repository }}

The name of the repository where the workflow runs are on.

3. retain_days

Required: YES

Default: 30

The number of days that is used to compare with the retention days of each workflow.

4. keep_minimum_runs

Required: YES

Default: 6

The minimum runs to keep for each workflow.

5. delete_workflow_pattern

Required: NO

Default: 'all'

The name or filename of the workflow. if not set then it will target all workflows.

6. delete_workflow_by_state_pattern

Required: NO

Default: 'all'

Remove workflow by state: active, deleted, disabled_fork, disabled_inactivity, disabled_manually

7. delete_run_by_conclusion_pattern

Required: NO

Default: 'all'

Remove workflow by conclusion: action_required, cancelled, failure, skipped, success

8. dry_run

Required: NO

Only log actions, do not perform any delete operations.

Examples

In scheduled workflow, see schedule event.

Tip: Using scheduled workflow is the recommended way that can periodically, automatically delete old workflow runs.

name: Delete old workflow runs
on:
  schedule:
    - cron: '0 0 1 * *'
# Run monthly, at 00:00 on the 1st day of month.

jobs:
  del_runs:
    runs-on: ubuntu-latest
    steps:
      - name: Delete workflow runs
        uses: Mattraks/delete-workflow-runs@v2
        with:
          token: ${{ github.token }}
          repository: ${{ github.repository }}
          retain_days: 30
          keep_minimum_runs: 6

In manual triggered workflow, see workflow_dispatch event.

In this way, you can manually trigger the workflow at any time to delete old workflow runs.
