The Bash Script Explained

This shell script appears to automate the installation of Docker and Docker Compose on a Linux system. Here's a breakdown of what each section of the script does:

1. Set Script Options:

set -o errexit
set -o nounset
IFS=$(printf '\n\t')

• set -o errexit: The script will exit if any command exits with a non-zero status.
• set -o nounset: The script will exit if it tries to use an uninitialized variable.
• IFS=$(printf '\n\t'): Internal Field Separator is set to newline and tab.

2. Install Docker

   apt install sudo -y && apt install curl -y
   curl -fsSL https://get.docker.com -o get-docker.sh
   sudo sh get-docker.sh
   printf '\nDocker installed successfully\n\n'

• Installs sudo and curl using the apt package manager.
• Downloads the Docker installation script using curl.
• Executes the Docker installation script using sudo sh.
• Prints a success message.

3. Wait for Docker to Start

   printf 'Waiting for Docker to start...\n\n'
   sleep 5

   • Prints a message indicating that the script is waiting for Docker to start.
   • Sleeps for 5 seconds.

4. Install Docker Compose:

   COMPOSE_VERSION=$(curl -s https://api.github.com/repos/docker/compose/releases/latest | grep 'tag_name' | cut -d\" -f4)
   sudo curl -L https://github.com/docker/compose/releases/download/${COMPOSE_VERSION}/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
   sudo chmod +x /usr/local/bin/docker-compose
   sudo curl -L https://raw.githubusercontent.com/docker/compose/${COMPOSE_VERSION}/contrib/completion/bash/docker-compose > /etc/bash_completion.d/docker-compose
   printf '\nDocker Compose installed successfully\n\n'
   sudo docker-compose -v

• Retrieves the latest Docker Compose version from GitHub API.
• Downloads Docker Compose binary using curl and installs it in /usr/local/bin/.
• Sets executable permissions for Docker Compose.
• Downloads Bash completion script for Docker Compose.
• Prints a success message.
• Displays the installed Docker Compose version.

Please note that this script assumes a Debian-based Linux distribution. If you are using a different distribution, adjustments may be needed. Additionally, it's essential to review and understand scripts before executing them, especially when using sudo commands from the internet.
