Phil Sphicas d161528ae8 Avoid calico-etcd crashloop 
Sometimes the calico-etcd pod crashloops when it is being bootstrapped.
This occurs intermittently in the gates.

Best guess .. when the etcd-anchor pod initially creates the etcd static
manifest, it waits for the anchor period (15 seconds) for the etcd pod
to become ready. If it is not ready, the next iteration through the loop
recreates an identical manifest. The fact that it is a new file causes
kubelet to terminate the original container and start up a new one.

Kubelet and the container runtime get out of sync, and kubelet can't
figure out the correct container id, so the pod ends up crashlooping
forever.  Manually removing and readding the manifest file doesn't
resolve the condition, although a kubelet restart actually does.

This "fix" will only write the updated manifest if it is different, and
hopefully will prevent the condition from occurring.

README.md

Promenade

Promenade is a tool for bootstrapping a resilient Kubernetes cluster and managing its life-cycle via Helm charts.

Documentation can be found here.

Roadmap

The detailed Roadmap can be viewed on the OpenStack StoryBoard.

  • Cluster bootstrapping
    • Initial Genesis process results in a single node Kubernetes cluster with Under-cloud components deployed using Armada.
    • Joining sufficient master nodes results in a resilient Kubernetes cluster.
    • Destroy Genesis node after bootstrapping and re-provision as a normal node to ensure consistency.
  • Life-cycle management
    • Decommissioning of nodes.
    • Updating Kubernetes version.

Getting Started

To get started, see getting started.

Configuration is documented here.

Bugs
