![]() ![]() Version : "3.2" services : app : image : traefik:v2.4 env_file : /var/data/config/traefikv2/traefikv2.env # Note below that we use host mode to avoid source nat being applied to our ingress HTTP/HTTPS sessions # Without host mode, all inbound sessions would have the source IP of the swarm nodes, rather than the # original source IP, which would impact logging. To deal with these gaps, we need a front-end load-balancer, and in this design, that role is provided by Traefik. We may not want to expose every interface on every container to the world, especially if we are playing with tools or containers whose quality and origin are unknown. No mechanism is provided for authentication outside of that which the container providers.Implementation would have to be done manually, per-container. There are some gaps to this approach though: We could stop there, just exposing a series of ports on our hosts, and making them HA using keepalived. So we get a rudimentary load balancer built into swarm. ( Docker calls this the swarm " routing mesh") ![]() When a container in a swarm exposes a port, then connecting to any swarm member on that port will result in your request being forwarded to the appropriate host running the container. If you want to try it right now, you can check this very simple project generator with a minimal Flask backend and Vue.js frontend.The platforms we plan to run on our cloud are generally web-based, and each listening on their own unique TCP port. It's actually very simple, as you can use Docker Compose for local development and then use the same files for deployment in the Docker Swarm mode cluster. The next thing would be to deploy a stack (a complete web application, with backend, frontend, database, etc) using this Docker Swarm mode cluster. mount type =volume,source =traefik-public-certificates,target =/certificates \ mount type =bind,source =/var/run/docker.sock,target =/var/run/docker.sock \ constraint =-public-certificates = true \ ![]()
