stevenaldinger/docker-gpg repository overview

⁠GPG Docker Image

This allows you to run GPG commands using your host machine's ~/.ssh and ~/.gnupg directories.

⁠Building docker image

In the Makefile⁠ there are commands for both building and pushing the image to DockerHub⁠.

# Builds an image named 'stevenaldinger/docker-gpg:latest'
make build \
  dockerhub_user='stevenaldinger' \
  version="latest"

# Pushes an image to 'stevenaldinger/docker-gpg:latest'
make push \
  dockerhub_user='stevenaldinger' \
  version="latest"

⁠Usage

In general, when you run this docker image it will make sure the GPG agent is running and then it will run any command you pass in.

⁠Run the gpg daemon container

⁠Example Docker Run

1. cd into the directory you want to export keys to.
2. Then run the container as a daemon:

docker run --rm --name gpg \
  -v "$HOME/.ssh":/root/.ssh \
  -v "$(pwd)/gnupg":/gnupg/USBDrive/gnupg \
  -d stevenaldinger/docker-gpg:latest \
  tail -f /dev/null

⁠Example Docker-Compose

The docker-compose.yml⁠ configuration runs tail -f /dev/null inside the container to keep it running and then the example files can be used to execute gpg commands inside the container.

Run make run to run a stevenaldinger/docker-gpg:latest container named gpg.
