Docker-Compose mount volume overwrites host files

问题

I am mounting a directory from a CMS with content files inside a docker container.

The mounting works absolutely. The CMS got some basic files, which are copied into the mounted folder in the container during build. Then it will be mounted to a directory on the host. Now the files from the Container are also on the host. I can change them and they will be kept in sync.

If i restart my container docker-compose stop && docker-compose up -d the files on the host will be overwritten by the default ones from the container build.

Is there a possibility to force the local state of the file to overwrite the file in the container?

Kind regards

回答1:

maybe try configuring it as read only

docker run -v volume-name:/path/in/container:ro my/image

回答2:

You can set it as read only as gCoh answer. See the following for docker-compose:

volumes:
  - type: bind
    source: ./host-source-folder
    target: /container-folder
    read_only: true
