There was a problem hiding this comment.
I like the idea of using hostname. However, should we just pick the first host
HOST_IP=${HOST_IP:$(hostname -I | awk '{print $1}')} ?
The only case I could see multiple IP address is when we use --net=host. Even in that case, we might just pick the first IP in the list by default. Thoughts ?
