Validating a Local Edition Cluster

  1. Run the following command to check if the correct number of containers have been created. If the number of NoSQL containers is greater than 1, then one will be created as the seed node, and the remaining as non seed nodes. 
    docker service ls

    Example output:

  2. You can also see the placement of containers, on a node basis, by running the following command: 
    docker node ps $(docker node ls -q) --filter desired-state=Running | uniq

    Example output:

  3. To examine the current state of the cluster, go to the Cluster Manager container. Make note of the node where Cluster Manager is deployed. You can open another terminal and configure the Docker client to talk to that node. If the tml-cm container is deployed on node-1, open a new terminal and run the following commands in sequence. 
    1. eval "$(docker-machine env node-1)"
    2. docker ps
    3. docker exec -it <cm container id> /bin/bash

      You will see the list of commands you can execute within the container. Here is a common set of commands you may want to use: 

      1. [root@51ffa1197313 builder]# alias cm=clustermanager
 
2. [root@51ffa1197313 builder]# cm ls clusters
