Jan Christian Grünhage bc2e7a7366 chore: optimise Dockerfile

So far, the Dockerfile built hydrogen on the server running the image,
instead of building it during the building of the image. This blew up
the image size immensely and caused node+yarn to run in the resulting
image. This new Dockerfile builds hydrogen in a separate build stage and
then moves the target directory into an nginx based container image,
which takes care of serving the target webroot.

The existing Dockerfile has been moved to Dockerfile-dev for usage as a
development environment. The docs have been adjusted accordingly.

Additionally, this switched from a fixed alpine version of the node
image to the latest alpine version, and changed the container image
references in the `FROM` statements to use the fully qualified
references including the registry domain.

Warning

Usage of docker is a third-party contribution and not actively tested, used or supported by the main developer(s).

Having said that, you can also use Docker to create a local dev environment or a production deployment.

Dev environment

In this repository, create a Docker image:

docker build -t hydrogen-dev -f Dockerfile-dev .

Then start up a container from that image:

docker run \
    --name hydrogen-dev \
    --publish 3000:3000 \
    --volume "$PWD":/code \
    --interactive \
    --tty \
    --rm \
    hydrogen-dev

Then point your browser to http://localhost:3000. You can see the server logs in the terminal where you started the container.

To stop the container, simply hit ctrl+c.

Production deployment

Build or pull image

In this repository, create a Docker image:

docker build -t hydrogen .

Or, pull the docker image from GitLab:

docker pull registry.gitlab.com/jcgruenhage/hydrogen-web
docker tag registry.gitlab.com/jcgruenhage/hydrogen-web hydrogen

Start container image

Then, start up a container from that image:

docker run \
    --name hydrogen \
    --publish 80:80 \
    hydrogen
