This relates to the docker-compose repo, current HEAD. docker-compose is version 1.21.0, docker is version 18.09.1, build 4c52b90.
I’m running ttrss on a server where I run multiple services behind a traefik reverse proxy. The default method to connect a service to traefik is to have a external docker network, in my case called traefik_proxy
, to which the web service (in my case web-nginx
from ttrrs) is connected. The actual ttrss services are running in a ttrss_backend
network. web-nginx
is connected to both the proxy and the backend. Also, I have multiple other web servers connected to the traefik_proxy
network.
When running the unchanged docker-compose.yml, nginx would give a cgi fastpath error, indicating a refused connection. I found that web-nginx tries to resolve the name app
(as the service is called in the yml). This name is ambiguous in my setup, since it exists in ttrss_backend as ttrss_app_1, and in traefik_proxy as static_app_1
(serving a static website). In my case, app
was resolved as static_app_1
, not ttrss_app_1
.
I fixed this in the following way:
- gave
app
the attributecontainer_name: ttrss_app
- edited
web-nginx/nginx.conf
and replaced all occurences ofapp
withttrss_app
Since the problem and the workaround is specific to reverse-proxy setups with multiple docker networks, it probably wouldn’t make sense to adopt this as a config. May I suggest to add something about this to the readme?
