Nginx Proxy Manager volumes (+mailcow)

mf_bpd

I installed mailcow, and immediately afterwards I tried to install Nginx Proxy Manager.
The mailcow images start, but Nginx Proxy Manager keeps restarting. The error message is “ERROR: /etc/letsencrypt is not mounted. Check your docker configuration”
It does not print, but I suspect that the “data” volume is not mounted either.
The contents of docker-compose.override.yml are as follows:
"version: ‘3.8’
services:
nginx-proxy-manager:
depends_on:
nginx-mailcow:
condition: service_started
image: ‘jc21/nginx-proxy-manager:latest’
restart: unless-stopped
ports:
volumes:
npm-data:
driver_opts:
type: none
device: /opt/npm_data/data:Z
o: bind
npm-letsencrypt:
driver_opts:
type: none
device: /opt/npm_data/letsencrypt:Z
o: bind
networks:
default:
external: true
name: mailcowdockerized_mailcow-network
"

What could be the problem?
Thanks in advance for your help.

both NPM and mailcow try to bind port 80 and 443 on the host?

Please follow the instructions, and disable Lets Encrypt on mailcow.

Thanks esackbauer!

On the mailcow.conf the bind is as follows:
HTTP_PORT=8080
HTTP_BIND=127.0.0.1

HTTPS_PORT=8443
HTTPS_BIND=127.0.0.1
and
SKIP_LETS_ENCRYPT=y

The solution was to install the container in a container (/opt/npm).

Here is the content of docker/compose.yml:
version: ‘3.8’
services:
nginx-proxy-manager:
image: ‘jc21/nginx-proxy-manager:latest’
restart: unless-stopped
ports:
- ‘80:80’
- ‘443:443’
volumes:
- ‘./data:/data’
- ‘./letsencrypt:/etc/letsencrypt’
networks:
default:
external: true
name: mailcowdockerized_mailcow-network
