Docker add network to container

So as I don't have portainer and using the compose plugin its been great ive not missed anything until now

How can I add a network ive created to a container?

Network "ph_network"

There is no options too add it to the container my example "PiHole"

Is there a way?

You have to do it in the yaml file. In the last part of this procedure you have an example. https://wiki.omv-extras.org/do…_the_same_lan_as_the_host

So

    networks:
      mynet:
        ph_network

like this?

    restart: unless-stopped

used to click the button so never done it like this. does this look right?

edit = no check failed

error I get on the check

services.pihole.networks must be a list

I had created a MACVLAN's interface using the terminal (putty, for example)

Simply log in as root e copy & paste this:

IMPORTANT:

1. You need to modify "subnet=", "gateway=" and "ip-range=" to match you LAN.

2. Inside the OMV's web interface, under "Network" -> "Interfaces" you can see the name of the device that is necessary for "parent="

Code

docker network create -d macvlan \
    --subnet=192.168.0.0/24 \
    --gateway=192.168.0.1 \
    --ip-range=192.168.0.0/24 \
    -o parent=eno1 \
    -o macvlan_mode=bridge \
macvlan_home

Then, this is an example of a stack with the MACVLAN above:

Code

version: "3"


services:
  pihole:
    container_name: pihole
    image: pihole/pihole:latest
    hostname: pihole
    ports:
      - "53:53/tcp"
      - "53:53/udp"
      - "443:443/tcp"
      - "67:67/udp"
      - "80:80/tcp"
    environment:
      TZ: 'Europe/Rome'
      WEBPASSWORD: 'MY_PASSWORD' #Insert your password for admin's web page
      ServerIP: PI-HOLE_IP #Insert here the IP of your Pi-hole instance
      VIRTUAL_HOST: pihole.home
      PIHOLE_UID: 0
    volumes:
      - '/srv/dev-disk-by-label-DATI/AppData/Pihole:/etc/pihole/'
      - '/srv/dev-disk-by-label-DATI/AppData/Pihole/DNSmasq:/etc/dnsmasq.d/'
      - '/etc/localtime:/etc/localtime'
    cap_add:
      - NET_ADMIN
    restart: always
    networks:
      macvlan_home:
        ipv4_address: PI-HOLE_IP #Insert here the IP of your Pi-hole instance


networks:
  macvlan_home:
   external: true

Yea I nomrally make it via CLI also

sudo docker network create -d macvlan -o parent=enp2s0 --subnet=10.0.0.0/24 --gateway=10.0.0.1 --ip-range=10.0.0.200/32 ph_network

Just unsure how to add it in the compose. Ive never added the IP like you have ive used the network name.

Zitat von Thormir84

Just take a look at line number 7 in the code for the creation of MACVLAN's adapter: "macvlan_home" is only the name of the adapter.

Now, in the compose, see lines 18, 28, 29, 30, 33, 34, 35


NOTE: Why your "--subnet" and "--ip-range" are different?

Why is yours? ip-range is the IP you want for pihole from what ive read.

Ill check it out thanks

please read my guide, perhaps can help.

[HOWTO] install PIHOLE on OMV using portainer WEBGUI on a MacVlan

Ok, this is my forum.openmediavault.org/wsc/index.php?attachment/15496/ file, that you need to copy and edit acording your needs:


note that yaml file is a bit especial, pleae DO NOT USE TAB, use only SPACES on IT or do not work.

and Thanks to tonylawrence for your reference post

Please read about macvlan on dockers; is like if you create a virtual NIC

Now you need to create a stack like others in you install:

Thanks ive already made the macvlan just unsure how to add it via docker compose with portainer it was two clicks job done

networks:
   ph_network

must be something like the code above. Ill read some more today about it. can't be that hard to tell it use this network ive made.

Zitat von chente

Thormir84 has already explained it to you in post 6.

Look at the indentations.

The code that is indented at the same height as the service the network is generating.

The code that is indented inside the service is setting up that network inside the container.

It used to be like the code live the above I posted. I never added the IP into the compose before.

it just had ph_network in it the name of the macvlan ive made

So you are saying like this?

If so it fails the check.
