This change corrects two rendering issues in the kube-apiserver anchor
script. The details and impact are mentioned below.
1. The kube-apiserver anchor script fails to clean up some files from
the host, because the path is incomplete. For example, the cleanup()
function of the script includes:
rm -f "/host/acconfig.yaml"
instead of
rm -f "/host/etc/kubernetes/apiserver/acconfig.yaml"
2. A recent change to allow fileless command options [0] caused some
extraneous lines to end up in the script. For example, the rendered
script includes:
snapshot_files() {
cp "/tmp/etc/" "${SNAPSHOT_DIR}/etc/kubernetes/apiserver/"
}
compare_copy_files() {
SRC="${SNAPSHOT_DIR}/etc/kubernetes/apiserver/"
DEST="/host/etc/kubernetes/apiserver/"
if [ ! -e "${DEST}" ] || ! cmp -s "${SRC}" "${DEST}"; then
mkdir -p $(dirname "${DEST}")
cp "${SRC}" "${DEST}"
chmod go-rwx "${DEST}"
fi
}
cleanup() {
rm -f "/host/"
}
Since the 'cp' and 'rm' commands don't include '-r', this is actually
non-impacting, other than some log messages.

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
