This PS resolves a recent issue with Deckhand in which missing
substitution sources cause Promenade to fail during genesis,
while using Deckhand to render documents. The fix involves
introducing a new flag called fail_on_missing_sub_src which
if False logs a warning rather than raises an exception
in the event that a substitution source document is missing.
Also adds better exception handling and logging around
Deckhand.
Example error:

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 LCOO JIRA.
- 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 LCOO JIRA. If you find a bug, feel free to create a GitHub issue and it will be synced to JIRA.
