Windows Docker swarm overlay networking
Docker Swarm provides overlay networking which allows containers running on different nodes to communicate with each other seamlessly. Here are some general steps to set up Windows Docker Swarm overlay networking:
- Initialize a Docker Swarm: On the primary node, initialize a Docker Swarm with the following command:
csharpdocker swarm init
- Join nodes to the Docker Swarm: On each additional node that you want to join the Swarm, run the following command:
phpdocker swarm join --token <TOKEN> <IP_ADDRESS>:<PORT>
Replace <TOKEN>
with the token provided when you initialized the Swarm, and <IP_ADDRESS>
and <PORT>
with the IP address and port number of the primary node.
- Create an overlay network: To create an overlay network, run the following command on the primary node:
luadocker network create --driver overlay <NETWORK_NAME>
Replace <NETWORK_NAME>
with a name for your overlay network.
- Deploy services: Deploy services to the Swarm using the
--network
flag to specify the overlay network. For example, to deploy a service on the overlay network, run the following command:
cssdocker service create --network <NETWORK_NAME> --replicas 3 <IMAGE_NAME>
Replace <NETWORK_NAME>
with the name of your overlay network, <IMAGE_NAME>
with the name of the Docker image you want to use for your service, and --replicas
with the desired number of replicas.
- Verify network communication: Verify that containers running on different nodes can communicate with each other on the overlay network using the following command:
phpdocker service ps <SERVICE_NAME>
Replace <SERVICE_NAME>
with the name of your service. The command should show that each replica of the service is running on a different node.
By following these general steps, you can set up Windows Docker Swarm overlay networking and deploy services that can communicate with each other across different nodes.
