Container with all the dependencies required to run kubespray. To be able to ssh into the VMs from inside the container mount your ssh keys into /root/.ssh/

Step 1: Run docker container with local ssh keys (v1.0)

docker run -v ~/.ssh:/root/.ssh -it darumatic/kubespray:1.0

Dockerfile: https://github.com/darumatic/docker/blob/master/kubespray/Dockerfile⁠

For more information about kubespray: see http://kubespray.io⁠

Example for creating the ansible inventory file for a cluster with 2 VMs (One master / one node) from a VPS provider (Replace xx.yy.zz.vv with the ip address of a server):

Step 2: Create ansible inventory

kubespray prepare --nodes k8-poc-node1[ansible_ssh_host=xx.yy.zz.vv] --masters k8-poc-master[ansible_ssh_host=xx.yy.zz.vv] cat /root/.kubespray/inventory/inventory.cfg

NOTE: Ensure firewalls are disabled on the VMs otherwise the installation will fail, due to connectivity issues between cluster components. See https://coreos.com/kubernetes/docs/latest/kubernetes-networking.html⁠ for more information about which ports are required. Also your current user must be able to ssh into the VMs for ansible to work correctly

Step 3: Run the deploy task

kubespray deploy

Access cluster

kubectl is available in this container, use basic auth or certificates to connect to your new cluster.
