* Minor fixes to kubeadm 1.8 upgrade guide. (#5678)

- The kubelet upgrade instructions should be done on every host, not
  just worker nodes.
- We should just upgrade all packages, instead of calling out kubelet
  specifically. This will also upgrade kubectl, kubeadm, and
  kubernetes-cni, if installed.
- Draining nodes should also ignore daemonsets, and master errors can be
  ignored.
- Make sure that the new kubeadm download is chmoded correctly.
- Add a step to run `kubeadm version` to verify after downloading.
- Manually approve new kubelet CSRs if rotation is enabled (known issue).

Ahmet Alp Balkan ecf490b756 Document API client libraries
Add concept page about the Kubernetes API client libraries explaining what they
do and list officially-supported & community-maintained client libraries.

The list is obtained from https://github.com/kubernetes/community/blob/master/contributors/devel/client-libraries.md
and I am planning to add a notice there urging people to update the
/docs/reference/client-libraries.md when they add something there.

Alternatively we could remove that page altogether.

Eric Tune 4ff5587583 PodDisruptionBudget documentation Improvements (#4140)
* Changes from #3885

Title: Update PDB documentation to explain new field
Author: foxish

* Added Placeholder Disruptions Concept Guide

New file: docs/concepts/workloads/pods/disruptions.md
Intented contents: concept for Pod Disruption Budget,
 cross reference to Eviction and Preemption docs.
Linked from: concepts > workloads > pods

* Added placeholder Configuring PDB Task

New file: docs/tasks/run-application/configure-pdb.md
Intented contents: task for writing a Pod Disruption Budget.
Linked from: tasks > configuring-applications > configure pdb.

* Add refs to the "drain a node" task.

* Refactor PDB docs.

Move the "Requesting an eviction" section from:
docs/tasks/administer-cluster/configure-pod-disruption-budget.md
-- which is going away -- to:
docs/tasks/administer-cluster/safely-drain-node.md

The move is verbatim, except for an introductory sentence.

Also added assignees.

* Refactor of PDB docs

Moved the section:
Specifying a PodDisruptionBudget
from:
docs/tasks/administer-cluster/configure-pod-disruption-budget.md
to:
docs/tasks/run-application/configure-pdb.md
because that former file is going away.
Move is verbatim.

* Explain how Eviction tools should handle failures

* Refactor PDB docs

Move text from:
docs/tasks/administer-cluster/configure-pod-disruption-budget.md
to:
docs/concepts/workloads/pods/disruptions.md

Delete the now empty:
docs/tasks/administer-cluster/configure-pod-disruption-budget.md

Added a redirects_from section to the new doc, containing the path
of the now-deleted doc, plus all the redirects from the deleted
doc.

* Expand PDB Concept guide

Building on a little content from the old task,
greatly expanded the Disruptions concept
guide, including an abstract example.

* Update creating a pdb Task.

* Address review comments.

* Fixed for all cody-clark's review comments

* Address review comments from mml

* Address review comments from maisem

* Fix missing backtick

  /docs/samples revamp: move examples to /tutorials
  Copy-to-clipboard fix (#4190)
2017-06-26 11:54:33 -07:00
Ahmet Alp Balkan 9ec9c73466 /docs/samples revamp: move examples to /tutorials
Addresses the work described at #4134.

- Remove /docs/samples page: This page mostly had links to examples on
  kubernetes/kubernetes (examples dir) which is now at kubernetes/examples
  repository. It was linking to README.md files for tutorials. Now removing
  this page as we are moving tutorials from kubernetes/examples to here:

  - Create redirects from /docs/samples/ to /docs/tutorials/ (both JS and
    redirect_from).
  - Deprecate "MEAN Stack" tutorial: This tutorial overlaps quite a bit with
    existing "maintained" examples and has been out-of-date for a while.
    Creating an external redirect to its original and more up-to-date location:
    https://medium.com/google-cloud/running-a-mean-stack-on-google-cloud-platform-with-app-engine-and-mongolab-4bbd2040ea75

- Import README.md files of maintained examples (guestbook, wordpress+mysql and
  cassandra) to this repository and serve them under /docs/tutorial.

- Update /docs/tutorials ToC:
  - Link to imported tutorials.
  - Fix missing articles on sidebar (_data/tutorials.yml) and make the tutorials
    listed on tutorials/index.md available on the sidebar (closes #4007).
