Add Z Shell to any container

zsh-to-container.sh

#!/bin/bash
# Add Z Shell to any container

## 1. Ensure your container has git
## 2. Ensure your container has openssh and wget
  ## (checking os is not necessarily, fails will be failed 😉)
apt-get install openssh-client wget # apline
apk --update add openssh-client wget # debian
brew install openssh-client wget # mac 😂

## 3. Install zsh-in-docker with configs
sh -c "$(wget -O- https://github.com/deluan/zsh-in-docker/releases/download/v1.1.5/zsh-in-docker.sh)" -- \
    -t https://github.com/denysdovhan/spaceship-prompt \
    -a 'SPACESHIP_PROMPT_SEPARATE_LINE="false"' \
    -p git \
    -p ssh-agent \
    -p 'history-substring-search' \
    -p https://github.com/zsh-users/zsh-autosuggestions \
    -p https://github.com/zsh-users/zsh-completions
## Finally, run zsh:
zsh 
  ## (Again, some OSs do not support the `source` command (like "source ~/.zshrc"),
  ## so we just run a new one to make things simple 😉)
