1. The problem I’m having:
I run Caddy in Docker as reverse proxy but I can’t access the admin API
2. Error messages and/or full log output:
root@xy:/opt/work/compose/caddy# curl -vL http://localhost:2019
* Host localhost:2019 was resolved.
* IPv6: ::1

3. Caddy version:
Cady Version: v2.10.2 h1:g/gTYjGMD0dec+UgMw8SnfmJ3I9+M2TdvoRL/Ovu6U8=
4. How I installed and ran Caddy:
Caddy runs as container in Docker version 29.2.1, build a5c7197
Deployed with docker compose
a. System environment:
Ubuntu 24.04.4 LTS latest udates with plenty cores and ram
b. Command:
c. Service/unit/compose file:
configs:
caddy-basic-content:
file: ./config/Caddyfile
labels:
caddy: null
services:
caddy:
container_name: caddy
image: homeall/caddy-reverse-proxy-cloudflare:latest
restart: always
environment:
TZ: "Europe/Berlin"
CADDY_INGRESS_NETWORKS: caddy-proxy

volumes:

- ./caddy-data:/data
ports:

d. My complete Caddy config:
{
email xy@xy.de
auto_https disable_redirects
admin : 2019
metrics
log {
output file /data/log/caddy/access.log {
roll_size 10MB
roll_keep 5
}
}
}
*.xy.org, xy.org {
tls {
dns cloudflare token
resolvers 1.1.1.1
}
}
metrics.xy.org {
metrics
}
beacon.xy.org {
reverse_proxy 192.168.1.1
}
monitor.xy.org {
reverse_proxy 10.120.30.117:8080
}
reverse proxies are defined via labels in the according docker compose files, this works like a charm, just the admin API does not work not matter what I do. I would appreciate every hint and help
