Bash Booster

Bash Booster is a single file library, which provides various features useful during setup environment and preparing servers. It is inspired by Chef and was developed to be used with Vagrant. When Chef is too heavy, use Bash Booster, because it has been written using Bash only and requires nothing.

See full documentation at the project homepage.

Quick Start

Download ready to use library archive or...

1. Get the source code:

   :::bash
   $ hg clone https://bitbucket.org/kr41/bash-booster bash-booster
   $ cd bash-booster
   

2. Build the library:

   :::bash
   $ ./build.sh
   

3. Get the library at build/bashbooster.sh and use it!

Note for OS X users. OS X is shipped with an old version of Bash, so you need to get a new one using Homebrew.

:::bash
$ brew install bash

A traditional “Hello World” script looks like this (you can find it at examples/helloworld.sh):

#!/usr/bin/env bash

# Remove undesirable side effects of CDPATH variable
unset CDPATH
# Change current working directory to the directory contains this script
cd "$( dirname "${BASH_SOURCE[0]}" )"

# Initialize Bash Booster
source build/bashbooster.sh

# Log message with log level "INFO"
bb-log-info "Hello World"

It just prints a line to stderr:

helloworld.sh [INFO] Hello world

More interesting example, which demonstrates almost all features of Bash Booster you can find at examples/vagrant/bootstrap.sh. This script is used for provisioning virtual machines managed by Vagrant. A Vagrantfile placed at examples/vagrant sets up three virtual machines: ubuntu, centos, and debian. Bootstrap script installs Nginx web-server, builds Bash Booster documentation, and places compiled HTML into web-root directory. Just run:

:::bash
$ cd examples/vagrant
$ vagrant up

...and have some coffee, then visit:

• http://localhost:8081—Ubuntu machine
• http://localhost:8082—CentOS machine
• http://localhost:8083—Debian machine

If you run vagrant provision again, script will finish almost immediately. It happens, because it does not do unnecessary job: all packages installed, web-server configured, HTML compiled.
