Docker Tips

Docker

1. Remove all exited containers

   docker rm `docker ps -aq`
   

2. Update restart policy

   docker update --restart=always <container>
   

3. Before deployment, ensure that Docker's configuration file /etc/docker/daemon.json is ready, including mirror site, log rotation and many other useful settings.
