Hi, I do have docker volume called /usr/local/tomcat/webapps and it’s having sub folder inside of it. I would like to mount /usr/local/tomcat/webapps on host volume (/usr/share/tomcat/webapps) so that application team can check directly on host instead of logging into docker volume. I got many ex…

docker run -d \ -it \ --name devtest \ -v /path/on/host:/path/on/container\ nginx:latest or docker run -d \ -it \ --name devtest \ --mount type=bind,source=/path/on/host,target=/path/on/container \ nginx:latest Taken from: Use bind mounts | Docker Documentation

Hi Whats wrong with that way? If you need to provide data from the container on your host system, to mount it (using -v) into a container sounds like the perfect solution?

I’m not sure we 100% understand what you’re saying but I believe what you want to achieve is to give your application team access a specific folder in the container without them having to launch an interactive shell on the conainer. Personally I would achieve this using a bind mount: version: "3.8…

But you said: “I would like to mount /usr/local/tomcat/webapps on host volume (/usr/share/tomcat/webapps) so that application team can check directly on host instead of logging into docker volume.” and now you’re saying: “Nobody should be logging in to the host unless they are managing containers…

Haha good catch :sweat_smile: didnt see that

No problem. The fact that you didn’t disagree with my proposed solution makes me feel like maybe I’m actually starting to understand all this :wink:

If I get it right, the OP wants a container folder, with preexisting data from the image, to be available on the host. sikotic’s approach to use a named volume backed by a bind is already the best option there is, but it still has caveats. Named volumes provide a copy-on-first-use mechanism, where…

Thanks for the clear information. Yes, I ma able to view the container content on host by using named volume. Can you able to provide an example how to use in cli instead of docker compose? I have used below command and able to see container data in /var/lib/docker/volumes. May I know what comman…

Interesting. I was under the impression that bind mounts didn’t copy data. Are you saying that, if you create a volume which is a bind mount, and then reference it by name in your compose file, it still copies the data? The Docker run reference | Docker Documentation states the following: The `n…

Just to be clear, part 2: This one is not a volume backed by bind. It is a mount-bind. This will not copy the files from the image path back to a named volume, as there is no named volume involved.
