Ranch2Git keeps track of your Rancher stacks. It is supposed to be deployed as a Dockerimage. As such, it can be easily deployed with Rancher, making it really easy to use.

Automated builds of the image are available on Dockerhub and is the recommended method of installation.

docker pull gmentsik/ranch2git

Alternatively you can build the image yourself.

docker build -t ranch2git github.com/gmentsik/ranch2git

The recommended way of running ranch2git is to deploy it directly as service in Rancher.

1. Create a new Git-Repository on your host. This can be any Git-Repo on any host. Please note that currently only HTTP(S) is supported, since the main target is Github and GitLab

2. Make sure you have access to your repo with a username + password combination. (HTTP Simple Auth)

3. Add a new Account API Key in Rancher Rancher Web UI -> API -> Add Account API Key

4. You can copy&paste this docker-compose file in a new rancher-stack.

5. Replace the RANCHER_API_USER and RANCHER_API_PASS environmental variables with the generated User and Password.

version: '2'
services:
  ranch2github:
    image: gmentsik/ranch2git:latest
    environment:
      RANCHER_APIV2_URL: http://rancher-url.com/v2-beta
      RANCHER_API_USER: api-user
      RANCHER_API_PASS: api-user-password
      GIT_REPO_URL: https://github.com/username/repo.git
      GIT_REPO_USER: username
      GIT_REPO_PASS: password
      UPDATE_EVERY: 5m
    stdin_open: true
    network_mode: host
    tty: true
    labels:
      io.rancher.container.pull_image: always

*OR you can use the v1 API for older rancher versions

version: '2'
services:
  ranch2github:
    image: gmentsik/ranch2git
    environment:
      GIT_REPO_URL: https://github.com/username/repo.git
      GIT_REPO_USER: git-user
      GIT_REPO_PASS: git-password
      UPDATE_EVERY: 1h
    labels:
      io.rancher.container.create_agent: "true"
      io.rancher.container.agent.role: "environment"
    stdin_open: true
    network_mode: host
    tty: true

Alternatively, you can use the sample docker-compose.yml file to start the container using Docker Compose

You can use the v1 API by adding two labels to your service

  io.rancher.container.create_agent=true
  io.rancher.container.agent.role=environment

This will provide the three environment variables required to access the rancher api.

For debugging and maintenance purposes you may want access the containers shell. If you are using Docker version 1.3.0 or higher you can access a running containers shell by starting bash using docker exec:

docker exec -it ranch2git bash

everything happens inside the /root folder.

If you find this image useful here's how you can help:

• Send a pull request with your awesome features and bug fixes, to the dev branch.
• Help users resolve their issues.

Before reporting your issue please try updating Docker to the latest version and check if it resolves the issue. Refer to the Docker installation guide for instructions.

SELinux users should try disabling SELinux using the command setenforce 0 to see if it resolves the issue.

If the above recommendations do not help then report your issue along with the following information:

• Output of the docker version and docker info commands
• The docker run command or docker-compose.yml used to start the image. Mask out the sensitive bits.
• Please state if you are using Boot2Docker, VirtualBox, etc.
