Docker network best practice

[Kopernikus]

Hi,

 

Recently started with Unraid and already running some docker containers, but I was wondering about the docker networks?

I now I can run them as host, bridge, custom bridge and macvlan/ipvlan (optional on seperate interface/VLAN)

 

Ideal I would create a seperate VLAN for all my dockers, so they all have their own IP and because of the VLAN they can also talk to the host if needed, but I read on the forum this can cause crashes, is this true?

 

So what would be the best practice?

...that is exactly how I do that.

Custom Bridge and VLANs.

Just remember, that when talking to the host (on an another VLAN) traffic goes via your Router...so your Router needs some extra ressources to spare.

I*ve heard the same (can*t find the reference right now)...but AFAIR this is when a VM is attached to the same bridge.

I don*t use VMs or if so, like for my PBX, I pass through a real, dedicated NIC,
