-====== Ubuntu - Docker - Remove a container ======
-===== Remove one or more specific containers =====
-Use the **docker ps** command with the **-a** flag to locate the name or ID of the containers you want to remove:
-To list the containers:
-<code bash>
-docker ps -a
-</code>
-To remove the containers:
-<code bash>
-docker rm ID_or_Name ID_or_Name
-</code>
-----
-===== Remove a container upon exit =====
-If you know when you're creating a container that you won't want to keep it around once you're done, you can run **docker run --rm** to automatically delete it when it exits.
-Run and Remove:
-<code bash>
-docker run --rm image_name
-</code>
-----
-===== 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.
-To list the containers:
-<code bash>
-docker ps -a -f status=exited
-</code>
-To remove the containers:
-<code bash>
-docker rm $(docker ps -a -f status=exited -q)
-</code>
-----
-===== Remove containers using more than one filter =====
-Docker filters can be combined by repeating the filter flag with an additional value.  This results in a list of containers that meet either condition.  For example, if you want to delete all containers marked as either Created (a state which can result when you run a container with an invalid command) or Exited, you can use two filters:
-To list the containers:
-<code bash>
-docker ps -a -f status=exited -f status=created
-</code>
-To remove the containers:
-<code bash>
-docker rm $(docker ps -a -f status=exited -f status=created -q)
-</code>
-----
-===== Remove containers according to a pattern =====
-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**.  Note that these utilities are not supplied by Docker and not necessarily available on all systems:
-To list the containers:
-<code bash>
-docker ps -a |  grep "pattern”
-</code>
-To remove the containers:
-<code bash>
-docker ps -a | grep "pattern" | awk '{print $3}' | xargs docker rmi
-</code>
-----
-===== Stop and remove all containers =====
-You can review the containers on your system with **docker ps**.  Adding the **-a** flag will show all containers.  When you're sure you want to delete them, you can add the **-q** flag to supply the IDs to the **docker stop** and **docker rm** commands:
-To list the containers:
-<code bash>
-docker ps -a
-</code>
-To remove the containers:
-<code bash>
-docker stop $(docker ps -a -q)
-docker rm $(docker ps -a -q)
-</code>
