Phil Sphicas 3e28b0ee2d Fix kube-apiserver anchor script rendering
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

To get started, see getting started.

Configuration is documented here.

Bugs
