When you run docker push or docker pull, the index determines if you are allowed to access. This is different from Docker on Linux, which. In fact, it might be searching multiple registries that the index is aware of. Docker Desktop stores Linux containers and images in a single, large disk image file in the Mac filesystem. When you run docker search, it's searching the index, not the registry. These two solutions could have worked in the past as you may often find them online, but neither of them worked for me with Ubuntu-based Linux distros in 2018-2019 (Docker version > 17). A registry stores and serves up the actual image assets, and it delegates authentication to the index.
not tagged or not referenced by any container. This will prune all images that have no references, i.e. Do NOT do this to move Docker storage location To clean these up, Docker provides a built-in command to run garbage collection. This happened not to be enough to work with Docker and I had to move the Docker storage location to another larger partition. Kubernetes users can easily deploy pods with images stored in Harbor. I usually have separate root and home partitions, and given that Linux doesn’t take much space, I allocate 15-30G for my root partition. If Harbor is configured for HTTP, you must configure your Docker client so that it. In this post, I wrote down how to do that for my readership and future myself :)ĭocker containers are relatively large (> 1G) and by default Docker stores all containers in /var/lib/docker, which is located in the root partition of your Linux system. It happened to me several times that I didn’t have enough space in my root partition to store Docker containers and I had to move the Docker default storage location to another partition.
