Lab #2: Create an Overlay network
In this lab we are going to create a user defined Overlay network.
Pre-requisite:
Tested Infrastructure
| Platform | Number of Instance | Reading Time |
|---|---|---|
| Play with Docker | 2 | 5 min |
Pre-requisite
- Create an account with DockerHub
- Open PWD Platform on your browser
- Click on Add New Instance on the left side of the screen to bring up Alpine OS instance on the right side
- Create a swarm cluster
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
NETWORK ID NAME DRIVER SCOPE
7bbea9e2f1c4 bridge bridge local
99e0866a81c5 docker_gwbridge bridge local
180292624b34 host host local
pp47xrb8x4da ingress overlay swarm
1o0u8kqharpe myoverlay0 overlay swarm
e7e3f13ebea6 none null local
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
