Container Execution

You may find at some point you need to locally run the container or view the internal contents of the container.

Shell Access

If you are wishing to experiment with the container, it can be useful to start a shell session inside of the container - to shell into a container, run the following:

docker exec -it <container_name> /bin/bash

Or if you would like to mount a directory:

docker exec -v `pwd`:/workspace -it <container_name> /bin/bash

All images have bash installed.

Checking the build version

If you are experiencing issues with a container, it can be useful to determine the image digest. As each image is deterministic, the installed versions will be pinned.

To obtain the build version for the container:

docker inspect -f '{{ index .Config.Labels "org.opencontainers.image.release" }}' <container_name>

Or the image:

docker inspect -f '{{ index .Config.Labels "org.opencontainers.image.release" }}' ghcr.io/cardboardci/<image_name>
