Docker Image Size


Recommended Posts

Unraid notified me my docker image size is very large. When I looked my docker image is 21.5 GB. I'm not really sure what causes a docker image to grow that large. I've seen a few things about how to reduce your docker image but all of them state to try and figure out why it's that large. Can anyone help me figure out what I need to do to figure out the why and then reduce the docker image size?

Make sure anything writing to disk in your docker container is mapped correctly to an actual disk/share or it'll write to the docker image instead
