DevOps: Puppet, Docker, and Kubernetes

Run your first container in Kubernetes

Congratulations! You've built your own Kubernetes cluster in the previous sections. Now, let's get on with running your very first container nginx (http://nginx.org/), which is an open source reverse proxy server, load balancer, and web server.

Getting ready

Before we start running the first container in Kubernetes, it's better to check whether every component works as expected. Please follow these steps on master to check whether the environment is ready to use:

1. Check whether the Kubernetes components are running:

   # check component status are all healthy
   $ kubectl get cs
   NAME                 STATUS    MESSAGE              ERROR
   controller-manager   Healthy   ok                   nil
   scheduler            Healthy   ok                   nil
   etcd-0               Healthy   {"health": "true"}   nil
