Introduction

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.

Getting started

Installation

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

Quickstart

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

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
Make sure you have access to your repo with a username + password combination. (HTTP Simple Auth)
Add a new Account API Key in Rancher Rancher Web UI -> API -> Add Account API Key
You can copy&paste this docker-compose file in a new rancher-stack.
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

Environment Variables

Variable	Default Value	Description	Examples
RANCHER_APIV2_URL	""	The full URL to your Rancher API V2	`http://rancher.company1.com/v2-beta`
RANCHER_API_USER	""	The generated rancher API User	`2CE23B40FA3761K91C66`
RANCHER_API_PASS	""	The generated password of your rancher API User	`A2nO8r43jAMrXMQeJd5VpFvEYHKzYgKPSuuTt7ct`
GIT_REPO_URL	""	Full http URL to your Git-Repository	`https://github.com/company1/rancher-conf.git`
GIT_REPO_USER	""	Your Git-Username	`company1`
GIT_REPO_PASS	""	Your Git Password	`soVeryStrongPasswordCannotBeHacked`
UPDATE_EVERY	"5m"	The Frequency of the script execution.	`1m`, `10s`, `2h`

Labels (Rancher API V1)

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.

Shell Access

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.
