Lab 4: Create an Overlay network

Homework Lab : https://labs.play-with-k8s.com/

Create an overlay network called myoverlay0

docker network create --driver=overlay --subnet=192.168.1.0/24 --gateway=192.168.1.100 myoverlay0

Listout the networks in the host

docker network ls

View the details of network myoverlay0

docker network inspect myoverlay0

Create an encrypted overlay network

By default application data is not encrypted, to encrypt application data as well, we need to add –opt encrypted while creating Overlaynetwork.

docker network create -d overlay --opt encrypted encrypted_overlay
