Terraform Comment Syntax + When to Use It

Terraform supports a few comment styles, but using them well is more about intent than syntax: capturing why something exists, documenting tradeoffs, and making complex infrastructure choices understandable for the next person (including future you).

In the full guide, we cover:

• The comment syntaxes Terraform supports (single-line and multi-line)
• Where comments add real value (intent, constraints, edge cases) vs where they create clutter
• Practical examples for documenting variables, modules, and non-obvious decisions
• Tips for keeping comments consistent and maintainable across a team
