Listen for webhooks and execute a deployment script

By v-braun - www.dev-things.net.

Description

Express based HTTP Endpoint that listens to webhooks. Downloads a file named deploy.crane from the repository and executes it.

I use it with Gogs to deploy my Docker container to a production environment.

Installation

Standalone installation

Install it globally:

npm install container-crane -g

and then start it:

container-crane

As a Docker container

# (optional )Create a network for Gogs and container-crane (not port mappings required)
docker network create deployment-net

# Pull image from Docker Hub.
docker pull devthings/container-crane

# Use `docker run` for the first time.
# map the docker.sock from host within the container
# if you want to use docker commands in your deploy scripts 
# (to deploy "neighbor" containers).
docker run --name="container-crane" --net="deployment-net" --restart=always -d -v /var/run/docker.sock:/var/run/docker.sock -v $(which docker):/bin/docker devthings/container-crane

# Use `docker start` if you have stopped it.
docker start container-crane

# (optional) Restart your Gogs container within the deployment-net network
# docker run --name="gogs" --net=deployment-net // other params

Usage

Setup a webhook in your Gogs repository that points to the /gogs/ endpoint of the container-crane container:

Now you need a deployment script for your app. You can write it in bash or node (both is installed on the container-crane Docker image)

Create a file named deploy.crane within your repository.

Here is an example as a bash script:

#! /bin/bash
echo "stop the container"
docker stop my-app
echo "remove container"
docker rm my-app
echo "build image"
docker build -t my-app --force-rm=true http://gogs:3000/my-gogs-user/my-app.git
echo "run the container"
docker run --name=my-app --restart=always -d -p 3000:3000 my-app

NOTE: container-crane depends not on docker! The deploy.crane script depends on your hosting environment.

Now you can simply:

git push your-gogs-origin

After container-crane receive a POST request from Gogs, it parses the webhook request body and downloads a script named deploy.crane. When the file is downloaded it will be executed.
