1. Caddy version (`2.4.3):
2. How I run Caddy:
I am using 2 different docker-compose projects. The one I want to call via curl uses this configuration: symfony-docker/docker-compose.yml at main · dunglas/symfony-docker · GitHub
I added networks, extra_hosts… nothing worked.
a. System environment:
Docker-compose, Linux Mint 18.
b. Command:
Inside the different docker-compose project, I tried many variations of:
curl api.localost
curl apitest
d. My complete Caddyfile or JSON config:

3. The problem I’m having:
Docker-compose works perfect when I run it with SERVER_NAME="api.localhost:80" docker-compose up -d --build.
But completely isolated project having its own docker-compose, doesn’t see it at all. The best I got was empty response when I curl-ed to IP address I found via inspect.
4. Error messages and/or full log output:
There are none. The only response I get is this when I curl -i 192.168.112.4:
HTTP/1.1 200 OK
Server: Caddy
Date: Mon, 26 Jul 2021 11:03:23 GMT
Content-Length: 0
5. What I already tried:
I have been trying to solve this problem for last 3-4 days, nothing worked. I am absolute Docker+caddy noob, my first time of using them and so far, probably tried about 100 different combinations.
Most recommendations are to use host.docker.internal:host-gateway but that didn’t work either; although I use latest docker and it should work on Linux.
6. Links to relevant resources:
Most of stackoverflow answers are telling to use network in docker-compose, but none worked.
Just for reference: this is 100% for my local development, not production.
