Zentral deployment with docker-compose

This is a simple way of testing Zentral. Everything will run on the docker host.

Requirements

  • Docker, with the docker-compose command. Docker Desktop for Mac, for example.

  • the default URL for zentral is https://zentral. The zentral name must resolve to the docker host. With Docker Desktop for Mac, it is 127.0.0.1. Edit your /etc/hosts file.

Setup

Download the source:

git clone https://github.com/zentralopensource/zentral

Build and launch all the containers in the background:

docker-compose up -d

Wait until all the containers are created and started. You watch the web container logs with the following command:

docker-compose logs -f --tail=100 web

You should see something like:

web_1       | Launch known command "runserver"
web_1       | 2019-06-28 15:57:36,383 PID25 autoreload INFO Watching for file changes with StatReloader
web_1       | Performing system checks...
web_1       |
web_1       | System check identified no issues (0 silenced).
web_1       | June 28, 2019 - 15:57:38
web_1       | Django version 2.2.2, using settings 'server.settings'
web_1       | Starting development server at http://0.0.0.0:8000/
web_1       | Quit the server with CONTROL-C.

At this point, the app is up and running.

Note: It is normal to see database migration errors. All the zentral containers are waiting for the database to come up, and try to apply the migrations. Only one need to succeed!

Create a Zentral superuser:

docker-compose run --rm web createuser --superuser henry henry@zentral.pro

You should see something like that:

Launch known command "createuser"
Superuser henry henry@zentral.pro created
Password reset: https://zentral/reset/Mg/57k-ed34961f7af3efe96e8f/

Open the password reset link in a browser, set a password, and log in.

Commands for docker-compose

Start everything:

docker-compose up -d

Create (or promote) a superuser:

docker-compose run --rm web createuser --superuser henry henry@zentral.pro                               

Restart all the Zentral app containers (not the DB, Elasticsearch, …):

docker-compose restart web workers celery

Update Zentral:

git pull && docker-compose up -d web workers celery

List containers:

docker-compose ps

Follow web logs:

docker-compose logs -f web

Follow nginx logs:

docker-compose logs -f nginx

Follow workers logs:

docker-compose logs -f workers
