Delete Github Actions Workflows

deleteRuns.sh

#!/bin/bash

# This script uses the gh cli to delete all workflows in a repo
# Useful if you want to regularly clean up your workflows (e.g. to free up some shared storage)
# based on https://github.com/orgs/community/discussions/77039#discussioncomment-7685341

# the gh cli only allows to delete 20 workflows at a time, so we wrap it in a loop
# and set the exit condition to when no more workflows are available
while true; do
    # Fetch the list of workflow runs and extract the databaseId using jq
    database_ids=$(gh run list --json databaseId --jq '.[].databaseId')

    # Check if there are any databaseIds
    if [ -z "$database_ids" ]; then
        echo "No more databaseIds found. Exiting."
        break
    fi

    # Loop over each databaseId and delete the corresponding workflow run
    echo "Starting to delete workflow runs..."
    echo "$database_ids" | xargs -n 1 gh run delete

    # Sleep for a while to avoid hitting rate limits
    sleep 1
