With that docker will run the container using my local user if it exist or not into the container. Vault. The above command will create a new container with the specified name from the specified docker image. Those would normally reside on the host disk, and they would be mounted as a volume.

Import the base image: Run a simple cat inside the docker image: Let's run a basic command: You can also run an interactive shell: There seems to be an issue with /var subdirs not created: Next, pull a base image that’s compatible with the evaluation build, re-tag it and to a test-run: docker pull microsoft/windowsservercore docker run microsoft/windowsservercore hostname 69c7de26ea48 Building and pushing Windows container images. The thing is that I created a user named jonas523 which I want to execute a shell command. $ $ docker run --user 1234:5678 --rm -ti busybox / $ id uid=1234 gid=5678 / $ So unless you f*cked up somewhere else I find it pretty safe to run a single process container under any uid:gid except root:root , just tell everyone the appropriate uid:gid (not the username:groupname !) to use for the mounted volumes.

Docker provides application isolation and thus eliminates many issues caused by library and environment differences. sh` as a Docker `ENTRYPOINT` add a non-root user to the image; set a Docker `WORKDIR` to this user’s home directory; set a newly create user as a user to use when running this Docker image; Full `Dockerfile` is here: docker run --rm -it -v `pwd`:/developer ubuntu:sahil When you run this command, you effectively start the container and mount the current working directory in the /developer folder.
