#Docker remove container unused how to#
We have already covered a series on Docker, that explains how to install Docker, run applications into containers and automatically build docker images with dockerfile. A container image is a self-contained, executable package of an application that includes everything needed to run it: code, runtime, system tools and libraries, as well as configurations. It is being widely adopted by IT and cloud companies out there, to easily to create, deploy, and run applications.Ī container is a technology for visualizing operating systems, that enables an application to be packaged with everything needed to run it, allowing it to run independently from the operating system. Using CoreOS andĪdd the X-Fleet section to schedule the unit on all cluster nodes.Docker is an open-source, powerful, secure, reliable and efficient container platform that enables realistic independence between applications and infrastructure. In /etc/systemd/system/rvice with contents like below. If the /var/lib/docker directory is mapped into the container this script will also clean up orphaned Docker volumes. For this reason the Docker client and socket is mapped into the container. The image uses the Docker client to to list and remove containers and images. Use a bare * as this will be taken as a filename match. Part of the cleanup, then you should use *:* to match all images. If you want to keep ALL images or containers, effectively disabling this Therefore, the image foo/bar:tag will be matched by ANY of the following:īy default, both are set to **None** which is the same as the blank string. Note that KEEP_IMAGES, KEEP_CONTAINERS, and KEEP_CONTAINERS_NAMED are left-anchored bash shell pattern matching lists (NOT regexps).

WARNING: This script will remove all exited containers, data-only containers and unused images unless youĬarefully exclude them. Based on tutumcloud/image-cleanup andĬhadoe/docker-cleanup-volumes with some small fixes. This image will periodically clean up exited containers and remove images and volumes that aren't in use by a
