Replace all usages of the hyperkube image with standalone container
images for apiserver, controller, scheduler, and proxy.
Change-Id: I44392c7900a72edd35bc5afa1c50bec8e04f927f
gcr.io/google_containers/ no longer contains some of the image
versions we require, use the new location.
Change-Id: I8f9a976a35ca632d785dd4d05f2a55713bde8c3e
The /hyperkube prefix isn't required and causes problems when using
non-hyperkube images elsewhere.

This ps makes following changes to upgrade kubernetes from v1.17.3
to v1.18.6.
- Updated all references to k8s images to 1.18.6
- Updated command options and api object and versions based on
k8s 1.18 release notes:
https://kubernetes.io/docs/setup/release/notes/
- Uplifted uwsgi to 2.0.19.1 to align with other airship
components, and to bring in fixes and improvements.
- Added build-essentials and python3-dev packages to pass the zull
gate, which was looking for a c compiler.

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.

This updates the proxy chart to include the pod
security context on the pod template.
This also adds the container security context to set
readOnlyRootFilesystem flag to false

This PS includes changes to support k8s 1.16, these
changes would work with existing kubernetes version
as well. A seperate change would be done to uplift
kubernetes to 1.16.
Hyperkube short aliases are removed in k8s 1.15
https://github.com/kubernetes/kubernetes/pull/76953
- Rename binaries of kubernetes components in promenade and
corresponding anchor helm charts
- Kubelet flag --allow-priveleged is deprecated in k8s 1.15 and
removed in 1.16. Remove the flag from kubelet template. This
fix will be backward compatible as long as psp are defined.

This change updates the following components in the Promenade charts,
docs, and example bootstrap configuration:
Kubernetes 1.10.11 -> 1.11.6
CoreDNS 1.1.2 -> 1.1.3 (per k8s 1.11 recommendations)
Etcd 3.2.14 -> 3.2.18 (per k8s 1.11 recommendations)
Tiller 2.10.0 -> 2.12.1 (per Helm k8s support)
This change has been tested by the Promenade resiliency gate.

In K8S version 1.10, the proxy can sometimes get stuck believing that
some services do not have any endpoints. This seems to be triggered by
network instability, though the proxy doesn't seem to recover on its
own, while bouncing the pod fixes the issue.
This change adds a naive means of detecting and recoverying from this
(`iptables-save | grep 'has no endpoints'` in the liveness probe) that
may occasionally have false positives. As such, the liveness probe is
configured very conservatively to avoid triggering CrashLoopBackoff in
the event of a false positive.
Finally, there is a whitelist feature to help avoid false positives for
services that are known to legitimately have empty endpoints during the
course of normal operation (e.g. Patroni might manage such an endpoint
list).

* Updates version references
* Increase memory of test VMs due to higher usage with bump
* Move etcd chart scripts from /tmp to /tmp/bin
* Remove certificate signing options for controller manager
* Remove -a from `kubectl get pods`, since that is deprecated in 1.10
* Shorten liveness/readiness probe times for CoreDNS
Change-Id: I16db0370f1c619e16002dd58e29025eb1538691f
This PS bumps the version of K8s used to 1.8.6 which adds:
* prometheus metrics for the PodSecurityPolicy admission controller
* Numerious scheduler fixes
* fixes for overlay2 metrics
* fixes for podSecurityPolicy
Change-Id: Ib46ea1a68c9f34f83b04976f49230ae67f811e66
This change includes several interconnected features:
* Migration to Deckhand-based configuration. This is integrated here,
because new configuration data were needed, so it would have been
wasted effort to either implement it in the old format or to update
the old configuration data to Dechkand format.
* Failing faster with stronger validation. Migration to Deckhand
configuration was a good opportunity to add schema validation, which
is a requirement in the near term anyway. Additionally, rendering
all templates up front adds an additional layer of "fail-fast".
* Separation of certificate generation and configuration assembly into
different commands. Combined with Deckhand substitution, this creates
a much clearer distinction between Promenade configuration and
deployable secrets.
* Migration of components to charts. This is a key step that will
enable support for dynamic node management. Additionally, this paves
the way for significant configurability in component deployment.
* Version of kubelet is configurable & controlled via download url.
* Restructuring templates to be more intuitive. Many of the templates
require changes or deletion due to the migration to charts.
* Installation of pre-configured useful tools on hosts, including calicoctl.
* DNS is now provided by coredns, which is highly configurable.
