RethinkBD cluster with Traefik & Docker Swarm

The main key is to create two network interfaces, one will be used with traefik and the other one will be used for the containers to communicate with each other

In the yml file I called them application and traefik, then you need to tell Traefik via the labels to use one of them.

When you deploy a stack you will have a name for it, which is also used as a prefix for the netwroks .. etc, to make it simple we will use the environment variables, so that we can have a flixable yml file.

1. First export the project name, change my-project to whatever you like.

export PROJECT_NAME=my-project

2. Deploy your stack

docker stack deploy -c old_working.yml --prune $PROJECT_NAME

3. If you are not running ARM64 device, you need to use the official RethinkDB docker image as my image zaherg/rethinkdb:2.3.6 was built for ARM64 devices specifically.

4. Add docker.pi and rethinkdb.docker.pi to your /etc/hosts file so you can access them locally.
