Docker私有注册表-删除容器后访问注册表映像

Question

I created a private docker registry and successfully pushed and pulled some images.

The thing is, the private registry runs in a container and when I remove the container using

sudo docker rm [container name]

I realize that all my pushed images are lost after a new container has been created.

Is there a way to keep the images in a private registry even when that private registry container is removed and another created?

If you start your registry using the dev or local config (assuming the default sample config ), you can map the storage_path directory to a directory on the host machine using a volume mount -v .

Using a modified version of the quick start example:

docker run \
    -d --name registry \
    -e SETTINGS_FLAVOR=local \
    -e STORAGE_PATH=/registry \
    -v /tmp/registry:/registry \
    -p 5000:5000 \
    registry

This will store the registry's data on the host machine in /tmp/registry , and persist when the container stops.
