See Recommended antivirus exclusions for Hyper-V hosts for details. If you’re running antivirus, be sure you’ve excluded VHDX files from real time scans for better performance If you are using a virtual machine, you may be able to increase the disk size or attach an additional one. Another option (if it is an option) is to increase the disk size used by the Docker daemon. Optimize-VHD -Path $ \Docker\wsl\data\ext4.vhdx -Mode Full Side note You should also remove unused Docker images and containers using the docker system prune command. If I build more than one image, it’s increses every time. wsl -shutdown # Optimize the VHDX file to reclaim free space. Before building the image, disk space & /var/lib/docker/overlay2 size. # If you get file in use errors on the next step, not performing this step is the likely culprit. You may wish to exit Docker Desktop gracefully before this step. docker run -rm -privileged -pid = host docker/desktop-reclaim-space docker rmi docker/desktop-reclaim-space # Shutdown Docker and WSL 2. # Perform the TRIM commands and then delete the image we just used. If you’d like to know how to get the best out of your servers, we’d be happy to talk to you.# Run this as an Administrator, not all of these steps work as a regular Windows user. We also give recommendations to server owners on how to manage their server resources effectively. In such cases, we do further actions such as adding more disk space. Our monitoring script alerts us when the disk space goes above 75%, even after all the clean up tasks done. We automate these tasks using routine scripts.īut we do check the container contents and take necessary backups before removing them, to avoid no accidental deletion of data with the automated scripts. Manually clearing the images to create disk space every now and then, would be tiring. In case any container is using that image, it would show a warning message when you try to remove it. It is recommended to have persistent storage because, without it, all data will be lost once the container is shut down. You can do a batch-cleanup of containers by listing the untagged images and deleting them, using this single command: docker rmi $(docker images -f "dangling=true" -q) The command ‘docker images –filter “dangling=true”‘ will display untagged images, that are not used by any containers. Since the dangling images cause wastage of disk space, they need to be deleted periodically to clear up the disk space for efficient functioning of the server. The 'repo:tag' for dangling images would be shown as : or untagged when the command ‘docker images’ is executed. For instance, an Ubuntu Docker image may have ‘Ubuntu’ as the repository name and ‘latest’ as the tag.Īs the name suggest, a dangling image in Docker is something that is inactive and not being used by any other running images. To entirely wipe out all the Docker containers, the command used is: docker rm $(docker ps -a -q) What are dangling images?Įvery Docker image has a repository name and tag associated with it. docker rm $( docker ps -q -f status=exited) ‘docker rm’ command is then used to remove all the containers that are not running (exited).
