• Options to deploy the package to servers
  • Manual
  • Scripting
  • Configuration Management
    
• Scripting:
  • This is as good as the knowledge of person writing it
  • This is procedural in nature
• Scripting vs CM
  

Configuration Management (CM)

• This a practice of configuring servers or hardware with a declarative approach.
• CM tools generally are idempotent
• CM architecture and choices
  • pull based CM:
    • Node will communicate with CM Server
    • Agents needs to be installed
    • Examples:
      • Chef
      • Puppet
  • push based CM
    • CM Server will communicate with node
    • node details and credentials will be stored, no agent installation required.
    • Examples:
      • Ansible
• Ansible job roles
  • DevOps
  • Network Infrastructure

Softwares to be installed in your system

• List:
  • git
  • visual studio code
  • aws cli
  • azure cli
• Mac

Step 1: Review the Script:

• First, open the URL in your web browser or use a command-line tool like curl to download the script content to review. This is important to ensure that the script is safe to execute.

curl https://raw.githubusercontent.com/ClassroomTraining/Setups/main/mac/setup.sh

Step 2: Download the Script

• Once you’ve reviewed the script and confirmed it’s safe, you can download it using curl with the -o option to specify the output filename, or you can directly execute it in the terminal (shown in Step 3).

curl https://raw.githubusercontent.com/ClassroomTraining/Setups/main/mac/setup.sh -o setup.sh

Step 3: Make the Script Executable

• Change the permissions of the downloaded script to make it executable.

chmod +x setup.sh

Step 4: Execute the Script

• Now, you can execute the script. Since it involves installing software, you might need to run it with sudo to provide the necessary permissions, depending on what the script does.

sudo ./setup.sh

Steps to install on windows

• Launch your Powershell or Windows Terminal as administrator
• Now copy the following script and run in powershell

cd ~/Downloads
Invoke-WebRequest -Uri "https://raw.githubusercontent.com/ClassroomTraining/Setups/main/Windows11/setup.ps1" -OutFile "setup.ps1"
./setup.ps1

• This script will install chocolatey, git, visual studio code, aws cli and azure cli into your system
