Port 80

[iamagithublearner]

Hey i wanted to ask if i can run this on a pi which is already running as a NAS (OMV) , or do i NEED to have a seperate pi for this? while installing this , i realized this will run on default port 80? but thats also being used by OMV, i am not sure how that will work if i start both at same time, please let me know what i can do about this

You certainly can run this on a pi or other computer running other containers/services.

What you'll need to do is edit one of: /templates/docker-compose.yml.j2 /templates/pi-hole-docker-compose.yml.j2 /templates/docker-compose.yml.j2 /templates/shelly-plug-docker-compose.yml.j2 /templates/starlink-docker-compose.yml.j2

you'll want to find a section like ports:

• "80:80" the first 80 is the port exposed externally, so you'll want to edit it to something like:
• "3080:80"

hey i get this error, i tried rebooting too

[jerzerisz]

are you running this on the pi you're installing to? if so

can you run: docker ps

That will verify if you have docker running and your user has correct permissions to run docker commands, which would lead me to suspect an issue in your inventory.ini file.

[iamagithublearner]

docker ps returns this , seems like its no running?

[jerzerisz]

yep docker is running, do you have to run sudo? that might indicate a permissions issue

edit: Noticed the non default user dead, have you edited the inventory.ini file to use this user instead of the default pi user?

see: https://github.com/geerlingguy/internet-pi/pull/528/files

[iamagithublearner]

oh that worked, thanks! but now i have a new error

[jerzerisz]

Awesome.

Now we've circled back to the original issue.

Important bits are: 0.0.0.0:80: bind: address already in use

double check you updated the port mapping.

[iamagithublearner]

yeah my docker-compose.yml.j2 file looks like this

....
services:
{% if domain_name_enable %}
  nginx-proxy:
    image: nginxproxy/nginx-proxy:latest
    restart: always
    ports:
      - "3080:80"
    networks:
      - back-tier
      - front-tier
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - /var/run/docker.sock:/tmp/docker.sock:ro
{% endif %}
....

[iamagithublearner]

this is the only thing i changed , couldnt find more references of port 80:80

[jerzerisz]

Ok, That section is if you're using the nginxproxy feature, a little more advanced feature, i don't believe you're using. The line we're looking for is little different than i was expecting.

in the file: pi-hole-docker-compose.yml.j2

services: pihole: container_name: pihole image: pihole/pihole:latest restart: unless-stopped hostname: '{{ pihole_hostname }}' ports:

• "53:53/tcp"
• "53:53/udp"
• "67:67/udp" {% if domain_name_enable and domain_name and domain_pihole %}
• "38080:80/tcp" {% else %}
• "80:80/tcp" {% endif %}
• "443:443/tcp"

this - "80:80/tcp" is the line to change, the /tcp or /udp is specifying what protocol to map the port

[iamagithublearner]

oh , thanks! , so i should undo the changed i made earlier? for the nginxproxy ? i am not using it anyways

[iamagithublearner]

do i need to restart ansible or smth?

[iamagithublearner]
