Lab01 - Create Overlay Network under Docker Swarm
The overlay network is used to enable containers on different hosts to communicate. Under this lab exercise, we will see how to create Overlay network.
Pre-requisite:
Tested Infrastructure
| Platform | Number of Instance | Reading Time |
|---|---|---|
| Play with Docker | 5 | 5 min |
Pre-requisite
- Create an account with DockerHub
- Open PWD Platform on your browser
- Create 5 Node Instances by clicking on “hammer” sign on the left side of the UI interface
The following command will create a new overlay network called collabnet. All containers registered to this network can communicate with each other, regardless of which node they are deployed onto.
docker network create -d overlay collabnet
Displaying the overlay network
docker network ls
Inspecting the overlay network
docker network inspect collabnet
