This uses docker-compose to create a small network of containers:
|--> chat-node-1 (UDP Chat)
|
|--> chat-node-2 (UDP Chat)
.
.
.
|--> chat-node-X (UDP Chat)
Each container runs a UDP chat application.
To launch, just open a terminal, go to the same level with 'docker-compose.yml', and execute:
docker-compose up -d --scale node=X
Where 'X' is the number of chat nodes wanted - 2 is recommended at least.
This will spin up the Docker architecture.
Login to each container:
docker exec -it chat-node-X /bin/sh
And run in each container:
./chatapp.py
You will be prompted for the remote to chat with. In a 2-node exmample, the nodes will be named:
chat-node-1
chat-node-2
Enter "chat-node-2" in the prompt on 'chat-node-1' and vice versa. Begin chatting.
To quit (CTRL+C in the terminal if not called with -d option)
docker-compose down
