Hi. I wanted to give you an update concerning the loss of network adapters in containers. As it turns out, the problem isn't limited to strongswan specific containers. It also happened with a barebone alpine container today. Hence I changed the title of the issue.
Alpine container data:
image: alpine:latest
Network adapter config file
auto eth0
iface eth0 inet static
address 192.168.221.10
netmask 255.255.255.0
gateway 192.168.221.254
The VM uptime was 2 days and 6 hours.
Here is the docker inspect result from the VM:
docker inspect
gns3@gns3vm:~$ docker inspect cranky_allen
