Good practices regarding keeping disk usage to a minimum

Let's take a look at the most common ones: docker pull and docker build create new docker images. Each layer is cached and uses aufs, so it decreases disk usage by itself, but it's also leaving previous versions / layers dangling.

Where are Docker containers stored?

Docker volumes are stored by default in the /var/lib/docker directory, which can become a capacity and performance bottleneck. However, it is possible to change this location using a switch at startup of the Docker daemon.

How do I stop all containers?

Where are Docker images stored?

How do I run a docker image?

Do the following steps:

1. $ docker images. You will get a list of all local Docker images with the tags specified.
2. $ docker run image_name:tag_name. If you didn't specify tag_name it will automatically run an image with the 'latest' tag. Instead of image_name , you can also specify an image ID (no tag_name).

Is it safe to delete Docker volumes?

Docker is an open-source containerization platform that allows you to quickly build, test, and deploy applications as portable containers that can run virtually anywhere. ... Docker doesn't remove unused objects such as containers, images, volumes, and networks unless you explicitly tell it to do so.

What happens when you delete a docker volume?

The deletion of the container is needed since it is a named container and you will get a name conflict if you start a new container with the same name (i.e. the container is started with the --name option for docker run ). If the container had not been named, removing the old container could have been skipped.

Does Docker system prune remove volumes?

The basic usage of the command docker system prune is Remove unused data. Removes all unused containers, networks, images (both dangling and unreferenced), and optionally, volumes.
