Is --net=host mandatory ? iptables problem

[trompx]

Hello,

As defined here debops/ansible-ferm#63 I use ferm to manage iptables.
As soon as I start a container with the --net=host parameter, I can not update my iptables rules anymore. I get the error :

stderr: iptables v1.4.21: host/network `' not found

Is there a way to start the node_exporter container without --net=host ?

Thanks

This looks like a bug with ferment<->docker, probably happens to all containers started with --net=host..

You can start it without --net=host, but you won't have (host) network metrics. Better to deploy the node-exporter straight to your host, without using docker.
