Kubernetes and Docker

13 Oct 2015

It’s been a bit harder getting Kubernetes working with a docker image and docker machine, but here’s a setup using the most recent(1.0.6) docker images.

I’m using my fork of dinghy and the Docker toolbox.

My fork removes the dependency on brew’s docker and docker-machine.

Command to SSH pipe docker-machine. Replace dinghy with your machine’s name.

ssh -i ~/.docker/machine/machines/dinghy/id_rsa [email protected]$(docker-machine ip dinghy) -L 8080:localhost:8080

Copy/paste the docker-compose.yml file below into a directory and run docker-compose up.

Just don’t name the directory k8s since it seems to cause some issues when starting up. Compose names the images like k8s_master_1 and k8s seems to be reserved in Kubernetes.

docker-compose.yml

etcd:
  image: gcr.io/google_containers/etcd:2.0.13
  net: "host"
  command: /usr/local/bin/etcd --addr=127.0.0.1:4001 --bind-addr=0.0.0.0:4001 --data-dir=/var/etcd/data
master:
  image: gcr.io/google_containers/hyperkube:v1.0.6
  name: "master"
  net: "host"
  volumes:
    - /var/run/docker.sock:/var/run/docker.sock
  command: /hyperkube kubelet --api_servers=http://localhost:8080 --v=2 --address=0.0.0.0 --enable_server --hostname_override=127.0.0.1 --config=/etc/kubernetes/manifests
proxy:
  image: gcr.io/google_containers/hyperkube:v1.0.6
  net: "host"
  privileged: true
  command: /hyperkube proxy --master=http://127.0.0.1:8080 --v=2
