Make terminal great again – Oh-my-zsh + WSL + Ubuntu

Have you ever wondered how to go from this:

to this:

so you can do this:

Checkout following 8 steps.

Prerequisities:

• kubectl installed
• Windows 10 version 22000.0 or higher
• windows terminal and Ubuntu (I use 20.04) installed from MS store
• apt-get update

1. Install Zsh

sudo apt install zsh -y

2. Install oh-my-zsh

sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

3. Install kubectx and kubens

kubectx and kubens are tools that allow you to quickly switch between k8s context (kubectx) and namespaces (kubens). They however do not give you this cool up-down arrow search you saw on the clip. This is done with Fzf (see step 6).

sudo git clone https://github.com/ahmetb/kubectx /opt/kubectx
sudo ln -s /opt/kubectx/kubectx /usr/local/bin/kubectx
sudo ln -s /opt/kubectx/kubens /usr/local/bin/kubens

4. Install kube-ps1

kube-ps1 shows current context and namespace in terminal prompt, no more wondering whether you’re on right cluster or namespace ! 🦾

sudo git clone https://github.com/jonmosco/kube-ps1.git

5. Install zsh-autosuggestions

Cool plugin which suggest you commands as you type them.

sudo git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions

6. Install Fzf

Tool for filtering command-line, allows to jump through kubectx and kubens results. Checkout that tool as it has much more features.

sudo apt-get install fzf

7. Modify .zshrc file

Open your .zshrc file vim ~/.zshrc and paste following lines there:

you can also find ‘plugins’ section, source $ZSH/oh-my-zsh.sh should already be there either.

plugins=(git kubectl kube-ps1 kubectx zsh-autosuggestions)

source $ZSH/oh-my-zsh.sh
source ~/kube-ps1/kube-ps1.sh
PROMPT='$(kube_ps1)'$PROMPT
KUBE_PS1_SYMBOL_USE_IMG=false
KUBE_PS1_SYMBOL_ENABLE=false
KUBE_PS1_PREFIX=
KUBE_PS1_SUFFIX=

if you’re happy with your changes quit vim :x

if you’re not:
