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.
