Basic Chef Workstation Project
This document provides a comprehensive guide for installing and setting up Chef on Amazon Linux 2023. Follow these instructions to ensure proper installation and configuration.
- Launch an Amazon EC2 instance running Amazon Linux 2023.
- Connect to the instance using SSH.
Ensure that all system packages are up-to-date with the latest updates and security patches:
sudo yum update -y
To clone the repository from GitHub, follow these instructions:
-
Ensure Git is installed on your system. If not, install it using the following command:
For Amazon Linux 2023:
sudo yum install git -y
-
Clone the repository using Git. Open your terminal and run the following command:
git clone https://github.com/atulkamble/chef-project.git
-
Navigate into the cloned repository directory:
cd chef-project
Chef Workstation is a suite of tools for managing infrastructure and executing Chef recipes.
-
Download the Chef Workstation package:
wget https://packages.chef.io/files/stable/chef-workstation/24.4.1064/el/8/chef-workstation-24.4.1064-1.el8.x86_64.rpm
-
Install the downloaded package:
sudo rpm -Uvh chef-workstation-24.4.1064-1.el8.x86_64.rpm
Confirm that Chef Workstation is installed correctly by checking the version:
chef --version
If you encounter the error /opt/chef-workstation/embedded/bin/ruby: error while loading shared libraries: libcrypt.so.1: cannot open shared object file: No such file or directory
, resolve it by installing the necessary compatibility library:
sudo yum install libxcrypt-compat -y
-
Create a Chef repository:
chef generate repo chef-repo cd chef-repo
-
Create a Cookbook:
chef generate cookbook cookbooks/my_cookbook cd cookbooks/my_cookbook
-
Write a Recipe:
Edit the
recipes/default.rb
file in your cookbook:nano recipes/default.rb
Add the following content:
file '/tmp/greeting.txt' do content 'Hello, Chef!' end
Test your cookbook by executing Chef in local mode:
sudo chef-client --local-mode --runlist recipe[my_cookbook::default]
cat /tmp/greeting.txt
Here's a shell script to automate the setup and configuration process for your Chef project on Amazon Linux 2023:
