Kubectl output options

Let's look at some basic kubectl output options.

What / Why

Deploy key is a SSH key set in your repo to grant client read-only (as well as r/w, if you want) access to your repo.

As the name says, its primary function is to be used in the deploy process, where only read access is needed. Therefore keep the repo safe from the attack, in case the server side is fallen.

How to

1. Generate a ssh key

Outdated note: the process is a lot easier now: after you brew install postgresql you can initialize or stop the daemon with these commands: brew services start postgresql or brew services stop postgresql.

new out put may look like

To have launchd start postgresql now and restart at login:
  brew services start postgresql
Or, if you don't want/need a background service you can just run:
  pg_ctl -D /usr/local/var/postgres start

# Inspired by: https://stackoverflow.com/questions/42170380/how-to-add-users-to-kubernetes-kubectl
# this script creates a service account (user1) on a Kubernetes cluster (tested with AWS EKS 1.9)
# prereqs: a kubectl ver 1.10 installed and proper configuration of the heptio authenticator
# this has been tested on Linux in a Cloud9 environment (for MacOS the syntax may be slightly different)
