Minimal base image for hosting Django websites with Automatic Git Deployment functionalities including Webhooks
This image will pull your Django application code from a git repository with the goal to be displayed by a webserver (gunicorn). As soon as a new code is pushed to that repository, your Django application will be updated.
This image is based on "baseimage:0.9.19" which is very lightweight: it only consumes 6 MB of memory.
This tutorial will explain how to setup this docker-django-git with a Github repository but it can work with other git platforms such as Bitbucket.
Let's generate a SSH key with ssh-keygen -t rsa. This will produce a public key and a private key. Do not set any password.
The public key id_rsa.pub will be used as is. Open your Github repository, go to Settings, and then to Deploy keys. Add a new deploy key, set a title and copy/paste the public key.
The private key id_rsa will be converted to base64 by running base64 /path_to_your_key. This key will be used in the docker run command line.
Note: Copy the output be careful not to copy your prompt.
At the root of your git repository, you should see the following :
<NAME_OF_YOUR_DJANGO_PROJECT>/
manage.py
Open your Github repository, go to Settings, and then to Webhooks. Add a new webhook. Set the payload URL with http://your-domain-name.com:8555/<YOUR_GIT_HOOK_TOKEN>. The content type should be application/json.
docker run -d -e 'GIT_REPO=git@github.com:<YOUR-GIT-USERNAME>/<YOUR_GIT_REPOSITORY_NAME>.git' -e 'SSH_KEY=<SSH_KEY=BIG_LONG_BASE64_STRING_GOES_IN_HERE>' -e 'GIT_EMAIL=YOUR_GIT_EMAIL' -e 'GIT_NAME=YOUR_GIT_NAME' -e 'GIT_HOOK_TOKEN=<YOUR_GIT_HOOK_TOKEN>' -e 'DJANGO_PROJECT_NAME=<NAME_OF_YOUR_DJANGO_PROJECT>' bendebled/docker-django-git
You should now be able to access your django application with the following url : http://your-domain-name.com:8000
Alternately, you can pull a repository and specify a branch add the GIT_BRANCH environment variable:
docker run -d -e 'GIT_REPO=git@github.com:<YOUR-GIT-USERNAME>/<YOUR_GIT_REPOSITORY_NAME>.git' -e 'GIT_BRANCH=stage' -e 'SSH_KEY=<SSH_KEY=BIG_LONG_BASE64_STRING_GOES_IN_HERE>' -e 'GIT_EMAIL=YOUR_GIT_EMAIL' -e 'GIT_NAME=YOUR_GIT_NAME' -e 'GIT_HOOK_TOKEN=<YOUR_GIT_HOOK_TOKEN>' -e 'DJANGO_PROJECT_NAME=<NAME_OF_YOUR_DJANGO_PROJECT>' bendebled/docker-django-git
The following flags are a list of all the currently supported options that can be changed by passing in the variables to docker with the -e flag.
- GIT_REPO : URL to the repository containing your source code
- GIT_BRANCH : Select a specific branch (optional)
- GIT_EMAIL : Set your email for code pushing (required for git to work)
- GIT_NAME : Set your name for code pushing (required for git to work)
- SSH_KEY : Private SSH deploy key for your repository base64 encoded (requires write permissions for pushing)
- WEBROOT : Change the default webroot directory from
/var/www/htmlto your own setting - TEMPLATE_NGINX_HTML : Enable by setting to 1 search and replace templating to happen on your code
- DOMAIN : Set domain name for Lets Encrypt scripts
- GIT_HOOK_TOKEN : Auth-Token used for the docker-hook listener
- DJANGO_PROJECT_NAME : The name of your Django project
