Semantic Versioning

Given a version number MAJOR.MINOR.PATCH, increment the:

• MAJOR version when you make incompatible API changes
• MINOR version when you add functionality in a backward compatible manner
• PATCH version when you make backward compatible bug fixes

Semantic Versioning

MAJOR.MINOR.PATCH eg. 1.0.3

Terraform Refactoring to correct gpg keyring changes and to allow unattended install

Refactoring into Bash scripts

• The new script is considerably longer than the original so we created a bash script to make it easier to debug and install the Terraform CLI
• This provides better portability for use in future projects
• Gitpod Task File is .gitpod.yml
• Shebang tells the bash script what program will interpret the script Shebang
• ChatGPT recommends for more portable script #!/usr/bin/env bash (will search user’s PATH to search for bash executable
• For Debian/Ubuntu: #!/bin/bash will work
• If we are using a script in .gitpod.yml, we would need to point the script to a program to interpret it. eg. 'source ./bin/install_terraform_cli

Linux chmod for changing permissions

• In order for the script to run, we had to add executable permissions for the user to the file
• We did this by running this command: chmod u+x ./bin/install_terraform_cli chmod wikipedia
