Steps I took to set up my Z shell prompt the way I like

zsh-prompt-setup.sh

# NOTE: These steps assume that zsh is already installed

# Download and install iTerm2, which can be found here:  https://iterm2.com/downloads/

# Install oh-my-zsh (details and alternate installation instructions can be found here: https://github.com/ohmyzsh/ohmyzsh):
sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

# Install the Powerlevel9k theme for zsh (details for using the oh-my-zsh installation can be found here: https://github.com/Powerlevel9k/powerlevel9k/wiki/Install-Instructions#option-2-install-for-oh-my-zsh):
git clone https://github.com/bhilburn/powerlevel9k.git ~/.oh-my-zsh/custom/themes/powerlevel9k

# Update your ~/.zshrc to use the Powerlevel9k theme:
vi ~/.zshrc

# Add this line to use the theme:
ZSH_THEME="powerlevel9k/powerlevel9k"

# Install the nerd fonts via homebrew (details can be found here: https://github.com/ryanoasis/nerd-fonts#option-4-homebrew-fonts):
brew tap homebrew/cask-fonts
brew cask install font-hack-nerd-font
 
# Install a particular font to get the icons (Meslo is chosen here, but there are other fonts):
brew cask install font-meslo-nerd-font

# In iTerm2, go to Preferences > Profiles > Text and make the following changes:
# * For "Font", choose one of the Meslo Nerd fonts (I chose MesloLGLDZ Nerd Font)
# * Check the "Use a different font for Non-ASCII text
# * For the "Non-ASCII Font", choose the same font as the selection in the "Font" dropdown

# Install zsh autosuggest and zsh syntax highlighting plugins (from here: https://gist.github.com/dogrocker/1efb8fd9427779c827058f873b94df95):
# in my case, $ZSH_CUSTOM=/Users/jeff.johnson/.oh-my-zsh/custom/
git clone https://github.com/zsh-users/zsh-autosuggestions.git $ZSH_CUSTOM/plugins/zsh-autosuggestions
git clone https://github.com/zsh-users/zsh-syntax-highlighting.git $ZSH_CUSTOM/plugins/zsh-syntax-highlighting

# Update your ~/.zshrc to include the auto-suggest and syntax highlighting plugins:
vi ~/.zshrc

# Find the plugins array in your ~/.zshrc and add zsh-autosuggestions and zsh-syntax-highlighting to the list.  An example is shown below:
plugins=(
    git
    docker
    jsontools
    zsh-autosuggestions
    zsh-syntax-highlighting
    kube-ps1
)

# Customize how directories will appear by adding these lines into your ~/.zshrc:
POWERLEVEL9K_SHORTEN_DIR_LENGTH=1
POWERLEVEL9K_SHORTEN_DELIMITER=""
POWERLEVEL9K_SHORTEN_STRATEGY='truncate_from_right'

# This makes the directory on the prompt look like this:
/./c/t/powerlevel9k

# Which is this:
pwd
/Users/jeff.johnson/.oh-my-zsh/custom/themes/powerlevel9k

# ---------------------------------------------------------------
# Configure the right-hand prompt to show:
# * command status
# * current kubectl context
# ---------------------------------------------------------------
# Add the kube-ps1 plugin to your ~/.zshrc:
vi ~/.zshrc

# Find the plugins array in your ~/.zshrc and add kube-ps1 to the list.  An example is shown below:
plugins=(
    git
    # other plugins...
    kube-ps1
)

# Configure the prompt (I don't want/need to see the namespace; I just want to see the cluster my current context 
# is pointed at, configuration details can be found here: https://github.com/ohmyzsh/ohmyzsh/tree/master/plugins/kube-ps1):
POWERLEVEL9K_CUSTOM_KUBE_PS1='kube_ps1'
POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS=(status custom_kube_ps1)
KUBE_PS1_SYMBOL_USE_IMG=true
KUBE_PS1_NS_ENABLE=false
KUBE_PS1_DIVIDER=''

# OPTIONAL:  Get some iTerm themes from here: https://iterm2colorschemes.com/
# I like FirefoxDev and Wombat

If everything's wired up right, the prompt should look something like this (I did not include the k8s cluster name, but trust me - it's there):
