We use different tools and setup for production. We do not fully provide this part with the template. Why?

  1. It requires a lot of server configuration
  2. It heavily depends on your needs: performance, price, technology, etc
  3. It is possible to show some vulnerable parts to possible attackers

So, you will need to deploy your application by yourself. Here, we would like to cover some basic things that are not changed from deployment strategy.

The easiest deployment strategy for small apps is docker-compose and systemd inside a host operating system.

Production configuration

You will need to specify extra configuration to run docker-compose in production. Since production build also uses caddy, which is not required into the development build.

docker-compose -f docker-compose.yml -f docker/ config > docker-compose.deploy.yml

Pulling pre-built images

You will need to pull pre-built images from Gitlab to run them. How to do that?

The first step is to create a personal access token for this service. Then, login into your registry with:

docker login registry.gitlab.your.domain

And now you are ready to pull your images:

docker pull your-image:latest

See official Gitlab docs.

Updating already running service

If you need to update an already running service, them you will have to use docker service update or docker stack deploy.

Updating existing service. Updating existing stack.

Zero-Time Updates

Zero-Time Updates can be tricky. You need to create containers with the new code, update existing services, wait for the working sessions to be completed, and to shut down old containers.
