Docker with Treafik => 500 Error

[Fabb]

Hi All,

I'm trying to setup a working environment using Docker and I'm able to access the webpage but directly get a Jquery 500 Error on top of the page. I think this has something todo with Websocket but I'm not sure. Has anyone running this with Docker and what about this example ?

Hi Fabb,

Please use the following instruction: https://github.com/espocrm/documenta...ker/traefik.md.

Thanks a lot lazovic

It seems there it not that much wrong with my docker-compose file but what seems be an issue is the following:

websocket on network "traefik" and "internal"
app on network "traefik" and "internal"
mysql on network "internal"
daemon on network "internal"

In this case the websocket cannot connect to the mysql server. When I put all containers in the same network it's all fine.

I like to keep some traffic on an internal network only and only have the webcontainers in the traefik network but routing seems to go wrong then.

OK I got iy fixed by re-adding - traefik.docker.network= to the labels.
