LibreNMS Docker Static Address with ipvlan driver

Help
1

Hi All

Just wonder if anyone got the librenms docker working with a static address while using the ipvlan driver while using a single static ip address for services that get spawned during the docker-compose up.

The goal of this post is to configure the docker-compose.override.yml or nano docker-compose.yml file to assign a SINGLE static address to the container and for all the services that get spawn during the docker-compose up to use this same static address.

I have already created a network called ipvlan-net-librenms which in the same subnet as the attached interface on the VM that is hosting the container.

docker network create -d ipvlan
–subnet 192.168.2.0/24
–gateway 192.168.2.21
–ip-range=192.168.2.150/29
-o ipvlan=l2
-o parent=ens160 ipvlan-net-librenms

Thanks

When i configure the following in the docker-compose.yml

networks:
default:
external:
name: ipvlan-net-librenms

And I issue the docker-compose up command and inspect the network for ipvlan-net-librenms

I can see IP’s been assigned to each service from the ip-range above

I would like to use only one IP for the above.
