• preinstalled attic-client

See docs.md.

How to build the image locally?

On Linux

$ nix build
$ docker load -i result

On macOS

The easiest way to build the image is using a previously built version of the image:

$ echo << EOF >> cmd.txt
nix build
nix-env -iA nixpkgs.docker-client
docker load -i result
EOF
$ docker run -it                                                                   \
  -e PLUGIN_BINARY_CACHE=https://some-binary-cache.example.com                     \
  -e PLUGIN_BINARY_CACHE_PUBLIC_KEY=some-binary-cache.example.com:some-public-keyi \
  -e PLUGIN_BINARY_CACHE_TOKEN=$ACCESS_TOKEN                                       \
  -e PLUGIN_SCRIPT="$(cat cmd.txt)"                                                \
  -v $(pwd):/opt/plugin                                                            \
  -w /opt/plugin                                                                   \
  -v /var/run/docker.sock:/var/run/docker.sock                                     \
