In order to enable Portainer, the docker-compose.yml and site.conf for Nginx must be modified.
1\. Create a new file `docker-compose.override.yml` in the mailcow-dockerized root folder and insert the following configuration
```
version: '2.1'
services:
portainer-mailcow:
image: portainer/portainer
volumes:
- /var/run/docker.sock:/var/run/docker.sock
- ./data/conf/portainer:/data
restart: always
dns:
- 172.22.1.254
dns_search: mailcow-network
networks:
mailcow-network:
aliases:
- portainer
```
2a\. Create `data/conf/nginx/portainer.conf`:
```
upstream portainer {
server portainer-mailcow:9000;
}
map $http_upgrade $connection_upgrade {
default upgrade;
'' close;
}
```
2b\. Insert a new location to the default mailcow site by creating the file `data/conf/nginx/site.portainer.custom`:
```
location /portainer/ {
proxy_http_version 1.1;
proxy_set_header Host $http_host; # required for docker client's sake
proxy_set_header X-Real-IP $remote_addr; # pass on real client's IP
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_read_timeout 900;
proxy_set_header Connection "";
proxy_buffers 32 4k;
proxy_pass http://portainer/;
}
location /portainer/api/websocket/ {
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $connection_upgrade;
proxy_pass http://portainer/api/websocket/;
}
```
3\. Apply your changes:
```
docker-compose up -d && docker-compose restart nginx-mailcow
```
Now you can simply navigate to https://${MAILCOW_HOSTNAME}/portainer/ to view your Portainer container monitoring page. You’ll then be prompted to specify a new password for the **admin** account. After specifying your password, you’ll then be able to connect to the Portainer UI.
