[garloff]

Is something wrong with the network (netplan) config? If I add ip link add link eno1np0 name vlan100 type vlan id 100; netplan apply, this script starts to work.

[garloff]

And ip link add link eno1np0 name vlan101 type vlan id 101 is needed as well. bootstrap.sh && deploy.sh then succeeds.

[garloff]

And this somehow needs to be persisted, so the system survives a reboot.

[garloff]

I wonder if this is a netplan bug. The settings in 01-osism.yaml look correct to me and according to the docs, I would have expected netplan to bring up these vlan ifaces.

[garloff]

I could not find a way how to tell netplan to bring up the vlan links, so I injected a custom systemd unit into the boot process. This is certainly not the intended way to do things.

dragon@manager:~$ cat /etc/rc.network 
#!/bin/bash
if test "$1" = "start" -o "$1" = "restart"; then
        ip link add link eno1np0 name vlan100 type vlan id 100
        ip link add link eno1np0 name vlan101 type vlan id 101
        netplan apply
fi

Please paste /etc/netplan/01-osism.yaml.

Looks correct to me ...

This was probably fixed with https://github.com/osism/ansible-collection-commons/pull/637.
