docker-list-context -- list files taken by Docker in a build context

docker-list-context lists files which are sent by the docker build command to the Docker daemon as the build context.

You can reduce the build context (better performance, avoid leaking secrets) by ignoring files in a .dockerignore file. The official documentation for .dockerignore files is here: https://docs.docker.com/build/building/context/#dockerignore-files

Tip: you can even ignore Dockerfile and .dockerignore, unless those files are referenced in the Dockerfile.

Usage

List context files for docker build . (using Dockerfile.dockerignore or .dockerignore):

$ docker-list-context

List context files for docker build -f Prj1 . (using Prj1.dockerignore or .dockerignore):

$ docker-list-context -f Prj1 .

Install

$ go install github.com/dolmen-go/docker-list-context@latest
