docker-get

Like go get, but for docker.

Features

  • Pull* docker images from git repositories.
  • Repository URL + path in repo is mapped to the docker image name.
  • Git tags / branches / commit ids are mapped to docker image tags.
  • Supports any repository your git can pull.
  • Git cache in $DOCKERPATH (by default ~/.docker-get).
  • Portable: written in 100% POSIX sh

*(git pull and docker build)

Get it

  • Download the latest version and make it executable:

    curl -LO https://raw.githubusercontent.com/32b/docker-get/latest/docker-get
chmod +x ./docker-get

  • A pre-built docker image is also available:

    docker pull quay.io/sergey_grebenshchikov/docker-get:latest

  • If you already have docker-get and just want to update the image:

    docker-get https://github.com/32b/docker-get

Use it

docker-get URL[:TAG]

Any further arguments/flags are passed to docker build.
