Swarm mode DNS

[JonDum]

Hello, I'm trying out dinghy because regular ol' docker for mac is slow as molasses with large bind mounts.

My stack consists of several docker stack deploy on a docker swarm running just the host machine in single node.

Dinghy comes up fine and all my containers seem much faster! 👍

Where I'm stuck is the dns resolving. With vanilla d4m Traefik was bound to localhost:80 so it could automatically proxy to my containers. That doesn't seem to work anymore since I can't figure out what the dns names are supposed to be.

I've tried: <service_name>, <service_name.docker>, <container_name> <container_name.docker> and I've tried manually connecting to the ip:port that dingy ip reports.

Still nothing connects. Does dinghy not support swarm mode?

[codekitchen]

I've never used swarm mode and I'm not familiar with how it configures the containers, so it's likely that Dinghy doesn't fully support it. Currently, the DNS names are based on the com.docker.compose.project and com.docker.compose.service labels that docker-compose sets on containers, or alternatively you can explicitly set a hostname by setting the VIRTUAL_HOST env var on a container. You can see the logic at the bottom of the nginx template: https://github.com/codekitchen/dinghy-http-proxy/blob/master/nginx.tmpl#L238

If swarm sets similar labels on containers, it may be as easy as just extending the logic in that template. But I'm not positive that's all that would be required, for instance I'm not sure if swarm sets up the virtual networks in a similar way to what compose does.

But are you saying you also can't connect to just http://$(dinghy ip)? That should respond with a "Welcome to the Dinghy HTTP Proxy" placeholder page, if it doesn't do that then something more might be going on.

But are you saying you also can't connect to just http://$(dinghy ip)?

Yea that's what's super weird. Nothing is connecting, but I can confirm they are running like normal through docker service log <stack>_<service>

ArangoDB is fairly straight forward so maybe that's a good one to look at — arangodb/arangodb:latest starts up the db and binds to :8529 (from its logs api_arango.1.t3z9rj3nlvle@dinghy | INFO using endpoint 'http+tcp://0.0.0.0:8529' for non-encrypted requests)

stacks/api.yml:

    arango:
        image: arangodb/arangodb:latest
        ports:
           - 8529:8529
        networks:
            - backend
        volumes:
            - arango_data:/var/lib/arangodb3
            - /var/run/docker.sock:/var/run/docker.sock

Could it be the attachable networks feature of docker swarm that is preventing them from communicating?

Inspecting some of the networks now:

All of my swarm containers appear to be under the ingress network. dinghy ip shows up as a "Peer" in this network.

$ docker network inspect ingress

Whereas dinghy-http-proxy shows up in the bridge network

$ docker network inspect bridge

Trying all the IPs I find in these, still don't get anything connected 😤
