This is necessary as Traefik doesn't support php-fpm.
This docker-compose.yml doesn't work:
version: '3'
services:
#php
...
#Nginx Service
webserver:
image: nginx:alpine
container_name: webserver
restart: unless-stopped
tty: true
volumes:

- traefik.http.routers.webserver.tls=true
- traefik.http.routers.webserver.tls.certresolver=lets-encrypt
- traefik.port=80
#Docker Networks
networks:

driver: bridge
traefik:
external: true
However, if I make an innocuous edit like change the version number to 3.7 (or change back to 3, from 3.7) it suddenly works, but isn't consistent.
How do I successfully route Traefik to an Nginx container?
#1. Docker compose file version is related to the engine, so please make sure you match that:
https://docs.docker.com/compose/compose-file/
#2. You could try to run the basic example from Traefik:
https://doc.traefik.io/traefik/user-guides/docker-compose/basic-example/
I'm assuming this is traefik latest (2.4)

I'm trying to set up 2 docker containers with docker-compose, 1 is a Traefik proxy and the other is a Vikunja kanban board container.
They both have their own docker-compose file. I can start the containers and the Traefik dashboard doesn't show any issues but when I open the URL in a browser I only get a Gateway Timeout error.
I have been looking at similar questions on here and different platforms and in nearly all other cases the issue was that they were placed on 2 different networks. However, I added a networks directive to the Traefik docker-compose.yml and still have this problem, unless I'm using them wrong.

I've tried adding the Traefik service to the Vikunja docker-compose.yml in one file but that didn't have any effect either.
I'm thankful for any pointers.
For debugging you could try to configure all container to use the host network to enusre they are realy on the same netwok.
i had a similar issue trying to run two different dockers and getting a
"Gateway Timeout". My issue was solved after changing the mapping in the second docker for traefik and accessing the site with :84 at the end (http://sitename:84)

Could you please suggest the solution for this issue why didn't get any response on the browser, and how to fix this issue?
So, I've setup several container apps that use MariaDB as their db backend, using docker-compose.
Containers are setup as needed and therefore MariaDB gets installed each time on every container that uses the db.
For example, I have some containers (PHPMyAdmin, NGiNX-PM, etc.) that use MariaDB, and they, in turn, have a version of it installed within their container. I also have a separate container (MariaDB) that I would rather have shared amongst the other containered apps and, thereby, I'd only have to maintain one version of the db.
I've searched for a solution, but no luck. Needless to say, I'm a noob at docker.
The only thing I can come up with is that all the apps need to be installed through the same docker-compose.yaml file to use the same db? That would make for a very long file if I had many containers running, and I'd prefer to have a directory per app and all the app's contents available in this one location.
I'm sure there is a way, I just haven't been able to figure it out.
So this is what I've tried:
The following setup is what I've tried but I am unable to get it to work:

Any help in this matter is greatly appreciated.
Ok, so after some more reading and testing, I've found the answer to my issue. I was assuming that "depends_on" was supposed to connect the containers, somehow. Not true!
I found that "external_links" is the correct way of connecting them.
So, my final docker-compose file looks like this:
(/docker/apps/nginxpm/nginxpm.yml)
version: '3.9'
networks:
NET:
external: true
services:
#############################################################################################
# NGiNX Proxy Manager (docker-compose -f nginxpm.yml up -d) #

nginxpm:
container_name: NGiNX_Proxy_Manager

- '443:443'

- ./data:/data

I have a docker compose container that runs Nginx. The site hosted is just a .test domain, like example.test.
Also in the container Nginx runs a location proxy and redirects it to example.test:8000. But it's not able to connect to that because that's actually being hosted from a different container on the same system (all bridged networks).
How can I let the containers communicate using example.test domain?
Or if I can't get them to communicate via example.test then how can I link them so they can use their docker-compose service name such as api or frontend?

With these current settings I get an error when I run it
ERROR: for 92b89f848637_opensrd_hosting_1 Cannot start service hosting: Cannot link to /opensrd_django_1, as it does not belong to the default network
Edit: Altered docker-compose.prod.yml:
networks:
app_net:
driver: bridge
ipam:
driver: default
config:
-
subnet: 172.16.238.0/24
services:
django:
environment:
- MODE=PROD
networks:
app_net:
ipv4_address: 172.16.238.10
But this gives me an error.
ERROR: The Compose file './docker-compose.prod.yml' is invalid because:
networks.app_net value Additional properties are not allowed ('config' was unexpected)
networks.app_net.ipam contains an invalid type, it should be an object
So I tried the options given by #trust512 and #DimaL, and those didn't work.
However after deleting the network and links from my compose files, and removing the existing default network and built containers, it worked, and I can not refer between container using db, django, and hosting.
The only thing different is I changed the composer version from 3 to 3.5.
These are the final files for anyone interested:
version: '3.5'

You can use external_links (https://docs.docker.com/compose/compose-file/#external_links) or try to put all containers on the same virtual network.
As far as I understand you just want them (django and nginx) to be linked across composes?
Then a native solution would be to use external_links exampled here
And use it like this:
services:
[...]
hosting:
[...]
external_links:
- django_1:example
[...]
Where django_1 stands for the container name created by the compose you provided and example is the alias that the container will be visible inside Django container.
Other way round you can just point a example.test domain to a specific address by editing your /etc/hosts (provided you work on linux/mac)
for example by adding a record like
172.16.238.10 example.test
Where the address above would point to your django application (container).
The above can be achieved without altering your /etc/hosts by using native solution from compose (extra_hosts) documented here
Additionally if you prefer a static ip address for your django/nginx containers in case you stick to the /etc/hosts od extra_hosts solution you can utilize another native solution provided by compose that sets up a static ip for a chosen services, properly exampled here
A adjusted listing from the linked documentation:
services:
[...]
django:
[...]
networks:
app_net:
ipv4_address: 172.16.238.10
networks:
app_net:
driver: bridge
ipam:
driver: default
config:
-
subnet: 172.16.238.0/24
Hi I'm new to docker containers. I have the following setup:
The docker host is running on a Linux server, it is running 4 apps:
reverse-proxy (nodejs-based)
frontend container
backend container
active mq container
All of them are running in my-network
Here is the problem, I would like to re-route every urls that come into the reverse-proxy to where it suppose to be. And restriction is I can't use re-write the reverse-proxy, because it is not worthy to re-write
The following are the docker-compose.yml files
version: '3'
services:
backend:
image: tomcat/test:first
ports:
- "8080:8080"
networks:
- my-network
volumes:

depends_on:

ports:

services:
reverse_proxy:
container_name: proxy_container

- "3000:3000"
networks:
- my-network
volumes:
- "/home/lluo/config.json:/app/dist/config.json"
networks:
my-network:
external: true
And I bind the network ipv4_address to be 0.0.0.0
Please help me resolve this issue, it's been days.
Thank you very much!
