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.
| Platform | Number of Instance | Reading Time |
|---|---|---|
| Play with Docker | 5 | 5 min |
- 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
docker network ls
docker network inspect collabnet
