MySQL Automatically Restarting
<p><strong>Problem</strong>: </p>

<p>MySQL is shutting down after startup - even after mysqld reports "ready for connections". I'm simply using the publicly available mysql image.</p>

<p>Does anyone know if there is some kind of setting or error that would cause a restart? </p>

<p>The logs don't include any errors that would indicate a restart would happen. After the one restart, the database appears to work fine, but I'd REALLY like to avoid this initial restart, as it screws up automation pretty bad.</p>

<p><strong>Environment</strong>:</p>

<p>MySQL Version: 5.6.33 Docker Image</p>

<p>Platform: Ubuntu Trusty</p>

<p>Docker-Compose Entry:</p>

<pre><code>  myDatabase:
    image: mysql:5.6
    environment:
      - MYSQL_DATABASE=myDatabase
      - MYSQL_ROOT_PASSWORD=FakeyMcFakeFace
    command:
      - --port=3307
      - --sql-mode=NO_ENGINE_SUBSTITUTION
      - --max_allowed_packet=16M
</code></pre>

<p>After this normal shutdown, it starts up again and will report "ready for connections" again, after which it appears to stay up.</p>
