A declarative framework for resilient Kubernetes deployment.
354deab382
The existing liveness and readiness probes for kube-proxy are in need of adjustment. The current implementation is exec-based, which can be a resource concern, and is tied heavily to iptables, so is incompatible with ipvs. This change removes the exec-based liveness and readiness probes from the kube-proxy daemonset, and replaces them with HTTP probes of the healthz endpoint, following the direction that kubernetes seems to be taking.[0][1] The values.yaml interface to enable and disable the probes and set various parameters is also modified to use the helm-toolkit standard snippet.[2] Notably, the settings previously configurable under livenessProbe.config are now under pod.probes.proxy.proxy.liveness.params. 0: https://github.com/kubernetes/kubernetes/issues/81630 1: https://github.com/kubernetes/kubernetes/pull/75323 2: https://opendev.org/openstack/openstack-helm-infra/src/branch/master/helm-toolkit/templates/snippets/_kubernetes_probes.tpl Change-Id: I99ccbc2270a1f8a204417aa410868d04788dc60f |

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
Bugs are tracked in OpenStack StoryBoard.
