MySQL server has gone away

I get this error from time to time:

SQLSTATE[HY000] [2006] MySQL server has gone away

I just re-run the job multiple times until it works. This is my conf for MySQL setup:

- name: Setup MySQL
        uses: mirromutth/mysql-action@v1.1
        with:
          mysql database: test
          mysql user: test
          mysql password: test

After a lot of time with inconsistent errors, I did this:

(...)
env:
      MYSQL_ROOT_PASSWORD: password
          
    steps:
      (...) first steps, but the sooner you call MySQL, the better
      
      - name: Setup MySQL
        uses: mirromutth/mysql-action@v1.1
        with:
          mysql root password: $MYSQL_ROOT_PASSWORD

      (...) all other things that don't need MySQL

      - name: Wait for MySQL
        run: |
          while ! mysqladmin ping --host=127.0.0.1 --password=$MYSQL_ROOT_PASSWORD --silent; do
            sleep 1
          done

      (...) steps where you need MySQL

If you think it is a good approach, I don’t have a problem adding this note in the README file (and doing a PR) so new users don’t waste time.

Adding a sleep 15 command to wait for the mysql server to become available fixed this issue for me

- name: Wait for MySQL
  run: sleep 15
