Is it possible to restart mysql service without restart container?

[EKwongChum]

While using this reposity's image mysql:5.7 ,we may need to restart mysql some times.
Once we call service mysql restart command ,the container restarts.
But we do not want the container restarts at that time.
Is it possible to restart mysql service without restart container? thx.

Sysvinit and Systemd, aren't running in the container, so mysql is PID 1 and when it dies the container exits. If you wanted that behavior then you'd want to make a derivative Dockerfile to include an init system or another workaround of having a different process be PID 1, but that would also affect signals and logging.

You could also try asking over at the Docker Community Forums, Docker Community Slack, or Stack Overflow. Since these repos aren't really a user-help forum
