• Features
• Get it
• Use it

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.
