The world is multi-arch and you can easily leverage it!
If you need to delete running containers based on their lifetime, this handy combination of commands can help you. It deletes all containers running for more than 2 hours. HOUR=2docker ps –filter “status=running” | grep hours | awk ‘{if ($4 >=$HOUR) print $1,”must be deleted”; system(“docker rm -f ” $1)}’
Or, you can also try our rpm repository: The source code for the build can be found at https://github.com/Unicamp-OpenPower/docker-ce-releases.
One of the great advantages of using containers [1] is that it brings flexibility to you deployments. You can have a container configured with everything you need and move it around to be executed where you want, which is a time saving approach (and reminds me of the Java’s WORA [2]: write once, run anywhere).… Continue reading docker: creating multi-arch images
