Setting Up Secure SSH Connections Between GitLab and AWS<\/p>\n\n\n\n

Here’s a step-by-step guide to configure GitLab CI\/CD pipelines for deploying to AWS EC2 instances using SSH key authentication:<\/p>\n\n\n\n

1. Key Preparation<\/strong><\/h3>\n\n\n\n
    \n
  1. Convert PPK to PEM<\/strong> (using PuttyGen):\n
      \n
    • Open your existing PPK private key in PuttyGen<\/li>\n\n\n\n
    • Navigate to Conversions \u2192 Export OpenSSH key<\/li>\n\n\n\n
    • Save as a PEM file (e.g., my-key.pem<\/code>)<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Add the PEM file content to GitLab:\n
        \n
      • Go to your project \u2192 Settings \u2192 CI\/CD \u2192 Variables<\/li>\n\n\n\n
      • Add a new variable:\n
          \n
        • Key: SSH_PRIVATE_KEY<\/code><\/li>\n\n\n\n
        • Value: Content of your PEM file<\/li>\n\n\n\n
        • Check “Mask variable” and “Protect variable” options<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n\n\n\n
        • Generate public key from pem file and append that to AWS user .ssh\/authorized_keys\n
            \n
          • Run the following command in your terminal (Linux\/macOS\/WSL)<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n
            ssh-keygen -y -f \/path\/to\/your-key.pem > \/path\/to\/your-key.pub<\/pre>\n\n\n\n
              \n
