docker-reclaim-disk-space

Reclaim disk space by removing stale and unused Docker data.

This is the bash script, that does the following:

• prints the Docker disk usage information
• interactively prompts you for confirmation
• removes stopped containers
• removes orphan (dangling) images layers
• removes unused volumes
• removes Docker build cache
• shrinks the Docker.raw file on MacOS
• restarts the Docker engine (through launchctl on macOS or systemctl on Linux). Waits until the Docker is up and running after the restart.
• prints Docker disk usage once again

Usage

Using curl:

bash -c "$(curl -fsSL https://raw.githubusercontent.com/samoshkin/docker-reclaim-disk-space/master/script.sh)"

Or using wget:

bash -c "$(wget -qO - https://raw.githubusercontent.com/samoshkin/docker-reclaim-disk-space/master/script.sh)"

Or just clone the repo and execute the script:

git clone https://github.com/samoshkin/docker-reclaim-disk-space
./docker-reclaim-disk-space/script.sh

If you want to suppress interactive prompts, pass -y flag.

If you don't want to restart the Docker engine, pass the --no-restart flag.
