This branch includes a rollup series of commits from a fork of the
kubernetes repository pre 1.5 release because we didn't make the code freeze.
This additional effort has been fully tested and has results submit into
the gubernator to enhance confidence in this code quality vs. the single
layer, posing as both master/node.
To reference the gubernator results, please see:
https://k8s-gubernator.appspot.com/builds/canonical-kubernetes-tests/logs/kubernetes-gce-e2e-node/
Apologies in advance for the large commit, however we did not want to
submit without having successful upstream automated testing results.
This commit includes:
- Support for CNI networking plugins
- Support for durable storage provided by ceph
- Building from upstream templates (read: kubedns - no more template
drift!)
- An e2e charm-layer to make running validation tests much simpler/repeatable
- Changes to support the 1.5.x series of kubernetes
Additional note: We will be targeting -all- future work against upstream
so large pull requests of this magnitude will not occur again.

Curating Owners: cluster/juju
cc @castrojo @mbruzek @chuckbutler @marcoceppi
In an effort to expand the existing pool of reviewers and establish a
two-tiered review process (first someone lgtms and then someone
experienced in the project approves), we are adding new reviewers to
existing owners files.
If You Care About the Process:
------------------------------
We did this by algorithmically figuring out who’s contributed code to
the project and in what directories. Unfortunately, that doesn’t work
well: people that have made mechanical code changes (e.g change the
copyright header across all directories) end up as reviewers in lots of
places.
Instead of using pure commit data, we generated an excessively large
list of reviewers and pruned based on all time commit data, recent
commit data and review data (number of PRs commented on).
At this point we have a decent list of reviewers, but it needs one last
pass for fine tuning.
Also, see https://github.com/kubernetes/contrib/issues/1389.
TLDR:
-----
As an owner of a sig/directory and a leader of the project, here’s what
we need from you:
1. Use PR https://github.com/kubernetes/kubernetes/pull/35715 as an example.
2. The pull-request is made editable, please edit the `OWNERS` file to
remove the names of people that shouldn't be reviewing code in the
future in the **reviewers** section. You probably do NOT need to modify
the **approvers** section. Names asre sorted by relevance, using some
secret statistics.
3. Notify me if you want some OWNERS file to be removed. Being an
approver or reviewer of a parent directory makes you a reviewer/approver
of the subdirectories too, so not all OWNERS files may be necessary.
4. Please use ALIAS if you want to use the same list of people over and
over again (don't hesitate to ask me for help, or use the pull-request
above as an example)

Renames kube-dns configure files from skydns* to kubedns*
`skydns-` prefix and `-rc` suffix are confusing and misleading. Renaming it to `kubedns` in existing yaml files and scripts.

Juju automated charm testing shouldn't bootstrap
**What this PR does / why we need it**:
**Special notes for your reviewer**: This controls the tooling around our test automation. This is a low impact change to the k8s codebase, that will have a big impact on our CI infrastructure.
**Release note**:
```release-note
release-note-none
```
Juju bootstrapping is an act of cost. This should be an explicit action
by the tooling surrounding bundle-tester when testing a charm. Setting
bootstrap:false will allow us to get faster feedback at lower cost when
running the kubernetes charm under ci.
Inserts @chuckbutler, and @mbruzek as reviewers for the juju cluster directory.
Additional assignee of @marcoceppi and @castrojo to help handle overflow.

Removing the Storage plugin from the juju cluster master.json manifest file
**What this PR does / why we need it**: The Juju cluster fails to bring up the apiserver. Using the docker logs I see the API server complaining about a fatal error.

move '(master)' to end of message for uniformity
**What this PR does / why we need it**: This is a small polish operation on the kubernetes charm wrt juju status output.
**Release note**:
<!-- Steps to write your release note:
1. Use the release-note-* labels to set the release note state (if you have access)
2. Enter your extended release note in the below block; leaving it blank means using the PR title as the release note. If no release note is required, just write `NONE`.

```release-note

This changes the status output from:
```

Kubernetes running.
kubernetes/1 active idle 4 172.27.24.55 6443/tcp

to this:

kubernetes/1 active idle 4 172.27.24.55 6443/tcp

This changes the status output from:

Juju bootstrapping is an act of cost. This should be an explicit action
by the tooling surrounding bundle-tester when testing a charm. Setting
bootstrap:false will allow us to get faster feedback at lower cost when
running the kubernetes charm under ci. Additionally doesn't reset so
no communication attempt is made to the controller
Additionally add tox to test dependency list
The admission controller adds a default class to PVCs that do not require any
specific class. This way, users (=PVC authors) do not need to care about
storage classes, administrator can configure a default one and all these PVCs
that do not care about class will get the default one.

This commit imports the latest development focus from the Charmer team
working to deliver Kubernetes charms with Juju.
Notable Changes:
- The charm is now assembled from layers in $JUJU_ROOT/layers
- Prior, the juju provider would compile and fat-pack the charms, this
new approach delivers the entirety of Kubernetes via hyperkube.
- Adds Kubedns as part of `cluster/kube-up.sh` and verification
- Removes the hard-coded port 8080 for the Kubernetes Master
- Includes TLS validation
- Validates kubernetes config from leader charm
- Targets Juju 2.0 commands
This branch of the charm-store charm is tracking features targeted at
kubernetes based deployments, while the devel focus will continually be
in a state of experimentation and learning.
As all things awesome - deploy in lockstep from a source that has
extensive testing to ensure we aren't handing out experimental code that
hasn't been fully tested e2e w/ the kubernetes project.
- Changed check_for_ppa to be parameterized
- Added bash strictmode
- refactored the package_status method to consume variables and be a bit
nicer to future re-use of the method.
- Cut out extra echo -n statements in favor of tr -d or native awk
- Refactored branching logic paths to leverage double brackets
- normalized local variable annotation
- Updated globals to be all CAPS
- remainder of filbrandens feedback in validate-cluster.sh
This feature adds Juju provisioning to the kube-up script. It currently
parses out the pre-requisits on debian/ubuntu based systems and installs
them if they are missing.
From there we followed the integration path that was found in the
libvirt-coreos path, implementing the methods found in the boilerplate
and calling juju service calls. There are a few "arbitrary sleeps" in
the code to allow the cloud provider to settle and properly deploy.
These are work-around cases from the script executing faster than juju
was able to communicate from the state server to subsequent nodes. I
left comments inline at these points.
To exercise this:
export KUBERNETES_PROVIDER=juju
cluster/kube-up.sh
It will spin up a ref arch with 1 Kubernetes Master, 2 minions, and run
the cluster validation checks against the deployment. Bridging the gap
between the juju specific bits and the upstream recommended guides for
getting started with Juju.
To note, if you do not have a "current environment" set in Juju, it will
spin up the quickstart integration wizard in interactive mode, allowing
you to configure juju, and add the proper provider/use it. Otherwise it
assumes you're in the provider you wish to use, and will deploy there.
