Hi Pascal, I've some question about your docker-stack-this. I've Docker Swarm with 3 nodes and until the previous week, I used Docker Flow Proxy + Letsencrypt companion for manage different container. Sunday I decided to try Treafik because the Flow solution uses too much container. Using this command

docker service create
--name traefik
--constraint=node.role==manager
--publish 80:80 --publish 443:443 --publish 8080:8080
--mount type=bind,source=/var/run/docker.sock,target=/var/run/docker.sock,readonly
--mount type=bind,source=/var/tmp,target=/etc/traefik/acme
--network traefik-net
traefik
--entryPoints='Name:http Address::80 Redirect.EntryPoint:https'
--entryPoints='Name:https Address::443 TLS'
--defaultEntryPoints=http,https
--acme.entryPoint=https
--acme.email=[email protected]
--acme.storage=/etc/traefik/acme/acme.json
--acme.domains=myawesomesite.com
--acme.onHostRule=true
--docker
--docker.swarmmode
--docker.domain=myawesomesite.com
--docker.watch
--web

I can run traefik successfully. But in this case, I can't protect dashboard. So I decided to use a custom toml file, but I can't mount (with eval docker host mode) it correctly. I use this: https://gist.github.com/tehKapa/cd78c15e3b3655e7a78765595f446a9e

The only error that I have is "invalid mount config for type bind". Have you any suggestion?

Thanks!

I used this to store the pictures outside the repo.

Is it possible to do the same thing you did with the Portainer redirection using Pgadmin4? I'm trying to do this, but it always redirects to http://127.0.0.1/login?next=%2F and I want this: http://127.0.0.1/pgadmin4/login?next=%2F

pgadmin4:

In the repo traefik-manager-noacme,
If I put the container here domain.com/ it works normally. See branch 1.15
When I put the container domain.com/wordpress/, it breaks.

Don't understand why as caddy, nginx, portainer works using PathPrefixStrip.

Hey Folks!

I just finished a Docker Stack 3.1 compose file docker swarm mode. It work perfectly with play-with-docker and on my nodes. It rocks!

It runs:

1 instance of Traefik
3 instance of caddy
3 instance of caddy
3 instance of who by Emile

Now I’m trying to make it works with ACME and I’m stucked. Is there any gents who would enjoy adapting my Docker Stack with ACME and make the TLS magic happen?

Many cheers!
Pascal

P.S. This git project also have a setup where Traefik runs on workers nodes.

Was ask on Slack

Need to try this solution

traefik/traefik#563 (comment)

I need to review this:

toolproxy_socat.1.dog9q51gwkl3@node1    | standard_init_linux.go:211: exec user process caused "cannot allocate memory"

Traefik will not have direct access to docker daemon and haproxy will log suspicious connections.

using caddy:1.0.1

This image is stable in my prod. It should not be hard to make it work in this stack :)

In this case, we need to bypass socat

wip

Per example: traefik/traefik#766 (comment)

I'll test them and see if I should integrate them
