kubelife

kubelife

Kubelife is a CLI tool (and kubeadm wrapper) for setting up a single node (and therefore not production ready) kubernetes seed clusters.

Currently it is intended to be used with cloud vm providers such as digitalocean and hetzner (cloud).

how it operates

Kubelife expects a cluster.yaml file, which describes the infrastructure (servers/vm's) and some meta information. See (here)[] for a full example of a cluster.yaml file.

Kubelife expects a working ssh connection via unix ssh agent to all servers described in the cluster.yaml

When everything is configuted kubelife after executing will:

• run commands on all nodes via ssh
• ensures docker installation
• ensures kubeadm, kubelet, kubectl installation
• ensures further needed kubeadm componends
• installs some basic cli tools
• setup k8s master node on the in the cluster.yaml described primary_master node
• waits for primary_master setup
• joins worker nodes (as described in the cluster.yaml)

future

• currently the tool is for my private setups
• in the future this might evolve into a full fledged k8s lifecycle management tool for seed clusters
