Kubectl output options

Let's look at some basic kubectl output options.

Our intention is to list nodes (with their AWS InstanceId) and Pods (sorted by node).

We can start with:

kubectl get no

I use these ansible scripts (see also) to bring up kubernetes clusters, on centos and fedora. The scripts are awesome, but they put selinux into permissive mode, because, "tokens and selinux don't work together."

That's unfortunate, because one of the main things I'm doing when I turn up a kubernetes cluster is bug-hunting, and selinux can be a source of bugs.

I commented out the bit that put selinux into permissive mode:

#- name: Set selinux permissive because tokens and selinux don't work together
#  selinux: state=permissive policy={{ ansible_selinux.type }}
# when: ansible_selinux is defined and ansible_selinux.status == "enabled"

  Watch out, os.IsExist(err) != !os.IsNotExist(err)

  They are error checkers, so use them only when err != nil, and you want to handle
  specific errors in a different way!
  
  Their main purpose is to wrap around OS error messages for you, so you don't have to test
  for Windows/Unix/Mobile/other OS error messages for "file exists/directory exists" and
  "file does not exist/directory does not exist"

Using Go cgo

cgo has a lot of trap.
but Not "C" pkg also directory in $GOROOT/src. IDE's(vim) Goto command not works.
