Display the contents of the build context.
docker showcontext DIR
Docker does not show the contents of the build context it archives and sends to the Docker Engine during a build process. This plugin allows you to list all the files that would be archived by a docker build command pointing the same build context directory in DIR. All patterns stored in the .dockerignore, if present, file are also properly handled.
$ docker clip add lukaszlach/clips:showcontextIf you are in the project directory you can call docker showcontext to list all the files:
$ docker showcontext .
