Kubernetes via Docker Compose
So I’ve decided to revisit my Kubernetes development cluster setup. The Mark 2 setup uses Docker Compose to launch the Kubernetes cluster in Docker.
To try it out, clone the GitHub repository:
git clone https://github.com/vyshane/docker-compose-kubernetes.git
The project also comes with:
Starting Kubernetes on Linux
On Linux we’ll run Kubernetes using a local Docker Engine. You will also need Docker Compose as well as the kubectl tool. To launch the cluster:
Starting Kubernetes on OS X
On OS X we’ll launch Kubernetes inside a boot2docker VM via Docker Machine. You will need to have Docker Machine (v0.5.0 or newer), Docker Compose, and the kubectl tool installed locally. First start your boot2docker VM:
docker-machine start <name> eval "$(docker-machine env $(docker-machine active))"
Then, launch the Kubernetes cluster in boot2docker via Docker Machine:
The script will set up port forwarding so that you can use kubectl locally without having to ssh into boot2docker.
Checking if Kubernetes Is Running
kubectl cluster-info Kubernetes master is running at http://localhost:8080 KubeUI is running at http://localhost:8080/api/v1/proxy/namespaces/kube-system/services/kube-ui
Accessing Kube UI
You can access Kube UI at http://localhost:8080/ui.
To destroy the cluster
This will also remove any services, replication controllers and pods that are running in the cluster.
