Common Basic Requirements For kOps-Related Labs. Pre-Flight Check: - Kops

Before rushing-in to replicate any of the exercises, please ensure your basic environment is correctly set-up. See KOPS AWS tutorial for more information.

Basic requirements:

Configured AWS cli (aws account set-up with proper permissions/roles needed for kOps). Depending on your distro, you can set-up directly from packages, or if you want the most updated version, use pip (python package manager) to install by running pip install awscli command from your local terminal. Your choice!
Local ssh key ready on ~/.ssh/id_rsa / id_rsa.pub. You can generate it using ssh-keygen command if you don't have one already: ssh-keygen -t rsa -f ~/.ssh/id_rsa -P "".
AWS Region set.
- Throughout most of the exercises, we'll deploy our clusters in us-east-1 region (AZs: us-east-1a, us-east-1b, us-east-1c, us-east-1d, us-east-1e and us-east-1f).
- For real HA at the Kubernetes API level, you need 3 masters.

Using root to set up the utilities for all users on that machine (either ssh directly to root or switch to is by running sudo su -):

bash

cd ~
curl -LO https://dl.k8s.io/release/$(curl -s -L https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl
curl -LO https://github.com/kubernetes/kops/releases/download/$(curl -s https://api.github.com/repos/kubernetes/kops/releases/latest | grep tag_name | cut -d '"' -f 4)/kops-linux-amd64
chmod 755 kubectl kops-linux-amd64
mv kops-linux-amd64 kops
mv kubectl kops  /usr/local/bin

Alternatively, if you don't have root access and/or wish to keep the kops/kubectl utilities in your local profile:

bash

cd ~
curl -LO https://dl.k8s.io/release/$(curl -s -L https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl
curl -LO https://github.com/kubernetes/kops/releases/download/$(curl -s https://api.github.com/repos/kubernetes/kops/releases/latest | grep tag_name | cut -d '"' -f 4)/kops-linux-amd64
chmod 755 kubectl kops-linux-amd64
mv kops-linux-amd64 kops
mkdir ~/bin
export PATH=$PATH:~/bin
mv kubectl kops  ~/bin

Finally, some of our exercises use the jq utility which is available on modern linux distributions. Please ensure to install it as well.
