Lightweight shell script for daily kubernetes jobs

Usage:

./kubex.sh <arg1> <optional arg2>

You may need to change the permissions for the script to run

chmod 700 kubex.sh

• reduces the hassle of getting a login token, copying to clipboard and opening a proxy session
• easily switching between contexts without needing to remember complex context name (e.g. in AWS EKS)

arguments

l or --list-contexts         list all kubernetes contexts
                             use the index numbers to switch conexts with --context command

t or --token                 generates a login token and copies to clipboard

c=<context index>
or --context=<context index> switches to a context from the list
                             use l or --list to see the list

p or --proxy                 gets a token and copies to clipboard
                             opens Mac Chrome app with the login page
                             starts a proxy session
s [--profile=profile_name]
or or --setup [--profile=profile_name]
							 Configures aws to the given profile or to the global credentials if --profile is missing,
							 downloads aws-iam-authenticator into /usr/local/bin, and runs 'aws eks' commands for all the environments

note about the --proxy method

This opens Mac Chrome browser. If you prefer another browser or use Linux, just change the app path from /Applications/Google Chrome.app to your favorite app.

example

list contexts and switch to production:

$ ./kubex.sh --list-contexts
1 - arn:aws:eks:us-east-1:123123123123:cluster/staging
2 - arn:aws:eks:us-east-1:123123123123:cluster/production

$ ./kubex.sh --context 2
Switched to context "arn:aws:eks:us-east-1:123123123123:cluster/production".

tip - use zsh alias or create a symbolic link in /usr/local/bin/

Instead of going to the directory or copying this script all around - use zsh alias or create a symboly link for it in /usr/local/bin/

zsh - add this line to .zshrc (replace the path to your kubex.sh path): alias kubex="~/Documents/kubex/kubex.sh"

Alternatively - manually create a symbolic link

For example if the script is downloaded to ~/Documents/kubex/kubex.sh

ln -s ~/Documents/kubex/kubex.sh /usr/local/bin/kubex

Then, from anywhere you can always

$ kubex l
1 - arn:aws:eks:us-east-1:123123123123:cluster/staging
2 - arn:aws:eks:us-east-1:123123123123:cluster/production

Easier!
