When upgrading controlplane nodes, upgrading the kubelets should be done
as the last step after "kubeadm upgrade" was run on all of the control
plane nodes already.
Also apply consistency related cleanup to sections and section names.
Ubuntu 16.04.5 LTS
apt-mark unhold kubeadm && apt-get update && apt-get install -y kubeadm=1.14.x-00 && apt-mark hold kubeadm gives the below error
The following packages have unmet dependencies:
kubelet : Depends: kubernetes-cni (= 0.6.0) but 0.7.5-00 is to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
Unholding the kubelet with kubeadm fixes the problem.
lose apt-mark unhold kubectl when apt-get install kubectl. If not unhold kubectl, it would return the error follows:
``` shell
root@ecs-k8s-master:~# apt-mark unhold kubelet && apt-get update && apt-get install -y kubelet=1.15.0-00 kubectl=1.15.0-00 && apt-mark hold kubelet
kubelet was already not hold.

1. Replace net.ipv4.route.min_pmtu with net.core.somaxconn in the
example of using unsafe sysctls in containers, since the former is not
accessible within container namespace at all.
2. Not all net.* sysctls are namespaced. Explain the correct way to
identify the namespaced networking sysctls.
* fix path of game.properties file
It has been dowloaded to configure-pod-container/configmap/game.properties
* fix typo: kustomization instead of kusotmization
There's been a number of questions around the difference between the external.metrics.k8s.io and custom.metrics.k8s.io in #sig-autoscaling referring back to the HPA docs recently. Added links out to the design proposals for each and the relevant sections of the existing walkthrough docs.
* Updated IP Address for /etc/hosts
Tested on Minikube for macOS.
When using Minikube, the IP address listed in `kubectl get ingress` is the internal Minikube IP address and is not available on the web browser.
Added advice to the user that when using Minikube, add the Minikube IP address to the Hosts file instead of the IP address displayed in `kubectl get ingress`.
* Update ingress-minikube.md
* Adding alternative command to create namespace
As this is first place user look to find details to create a namespace, added an alternative command to create a namespace. Also, this is mostly used way to create namepsace instead of YAML.
* Correcting Formatting
Correcting formatting for changes
* Update namespaces.md
