Restart Router-advertiser service if one of critical processes running in Router-advertiser container exited or crashed abnormally.
Generally I follow the framework created by Joe to implement this feature in Router-advertiser container.
First, add supervisor-proc-exit-listener event listener option in Supervisord configuration file in Router-advertiser docker container. Supervisord will read a list of critical processes for which to monitor the unexpected crashed and exited.
Second, configure router-advertiser.service to always auto-restart the service if it stops, with a delay of 30 seconds. Also set a rate limit of 3 restarts within 20 minutes (1200 seconds).
On your switch device, please use docker ps command to list all running docker containers.
Then use docker exec -it container_id /bin/bash to login target container. Typing top command
on the shell will display all the processes dynamically and you will spot the process id of one
of the critical processes. Finally type the command kill -9 process_id to terminate one process.
After exiting the container, you can use watch -n 1 docker ps to dynamically see the restart
of Router-advertiser container.
