Environment for developing Kubernetes (the core project). Useful when developing on non-Linux hosts.
282
This image is for people who want to modify code belonging to the core Kubernetes project and compile and run a cluster locally on a non-Linux host through hack/local-up-cluster.sh. This is not a way to locally run a project that uses Kubernetes (for that use Minikube).
First, make sure you have the Kubernetes source on your host. In this example I will put it in the GOPATH, but its location shouldn't matter:
mkdir $GOPATH/src/k8s.io/
git clone https://github.com/kubernetes/kubernetes.git $GOPATH/src/k8s.io/kubernetes
Then run this image, binding your local docker socket and Kubernetes directory:
docker run -v /var/run/docker.sock:/var/run/docker.sock \
-v $GOPATH/src/k8s.io/kubernetes:/go/src/k8s.io/kubernetes \
--name k8s-dev --rm -it alex-charlton/k8s-dev /bin/bash
You are then free to edit Kubernetes from your host and then compile and run a cluster from your k8s-dev image:
root@bcc2570ffab1:/go/src/k8s.io/kubernetes# ./hack/local-up-cluster.sh
...
Local Kubernetes cluster is running. Press Ctrl-C to shut it down.
Logs:
/tmp/kube-apiserver.log
/tmp/kube-controller-manager.log
/tmp/kube-proxy.log
/tmp/kube-scheduler.log
/tmp/kubelet.log
To start using your cluster, open up another terminal/tab and run:
export KUBERNETES_PROVIDER=local
cluster/kubectl.sh config set-cluster local --server=https://localhost:6443 --certificate-authority=/var/run/kubernetes/apiserver.crt
cluster/kubectl.sh config set-credentials myself --username=admin --password=admin
cluster/kubectl.sh config set-context local --cluster=local --user=myself
cluster/kubectl.sh config use-context local
cluster/kubectl.sh
The local-up-cluster.sh script will output something similar to the above, when successful. To start using your cluster with kubectl, you can ssh into the container with docker exec -it k8s-dev /bin/bash and paste that last part.
