The Docker CLI has an extensive suite of commands built-in and it can be painful to remember all of them. So as part of our containers roadshow, we will be blogging about useful tips and tricks for working with containers. We all make mistakes and we all need to be able remove containers from time to time. So let's go ahead and start!

Remove one or more specific containers

Use the docker ps command with the -a flag to locate the name/ID of the containers you want to remove:

# list
docker ps -a

# remove
docker rm ID/nameID/name

Remove Container Upon Exit

If you want to cleanup after yourself, then you can automatically delete a container once it exists from runnable operation using the docker run --rm command.

docker run --rm image_name

Remove All Exited Containers

You can locate containers using docker ps -a and filter them by their status: created, restarting, running, paused, or exited. To review the list of exited containers, use the -f flag to filter based on status. When you've verified you want to remove those containers, using -q to pass the IDs to the docker rm command.

docker ps -a -f status=exited
docker rm $(docker ps -a -f status=exited -q)

Remove Containers Using More Than 1 Filter

Docker filters can be combined by repeating the filter flag with an additional value.

docker ps -a -f status=exited -f status=created
docker rm $(docker ps -a -f status=exited -f status=created -q)

Remove Containers According to Patterns

You can find all the containers that match a pattern using a combination of docker ps and grep. When you're satisfied that you have the list you want to delete, you can use awk and xargs to supply the ID to docker rmi. Please note this will only work on unix based systems.

docker ps -a |  grep "pattern”
docker ps -a | grep "pattern" | awk '{print $3}' | xargs docker rmi

Stop and remove all containers

You can review the containers on your system with docker ps. Adding the -a flag will show all containers. Then you can get funky and pass them to the stop or rm commands.

docker ps -a
docker stop $(docker ps -a -q)
docker rm $(docker ps -a -q)

Integrating ColdBox with Existing Code Series 5: Using Wirebox

Integrating ColdBox with Existing Code Series 5: Using Wirebox

Recently, I did a webinar on Refactoring Legacy Code and the question came up about whether or not it was possible to use ColdBox with existing code without converting everything to a ColdBox module or making changes to the existing codebase. In the first installation in this series, we took a tour of the various elements which make up ColdBox. In the second installation, we looked at creating layouts, views, and routes in the main site. In the third, we created a module and did the first integration of our existing code into our ColdBox site. In the fourth, we continued developing our module with a handler and passing variable back to Coldbox. Now we'll use Wirebox with and without ColdBox Modules to see how these approaches differ from a traditional approach.
