Matt McEuen fcaacf94a3 Add -e to pre_stop hooks 
This adds -e to the pre_stop scripts, so that they fail out if
any of their commands fail.  This is required, since it's the only
way to communicate whether there is an issue during pre_hook
execution.

"The logs for a Hook handler are not exposed in Pod events.
If a handler fails for some reason, it broadcasts an event."
https://kubernetes.io/docs/concepts/containers/container-lifecycle-hooks/#container-hooks

As an example, this issue was discovered when "touch /tmp/stop"
was failing silently due to a readOnlyRootFilesystem setting,
resulting in pods that would not successfully Terminate until
the grace period was exhausted.

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
