How to Manage Different Terraform Versions

Versioning is crucial when using Infrastructure as Code (IaC) tools like Terraform to ensure that there are no breaking changes in the code. Key points related to versioning include: 1. Stick to a specific version for your Terraform code and providers to avoid breaking changes. 2. Use a Version Control System (VCS) like git for collaboration between teams, reducing human errors. 3. Understand the widely accepted standard of defining versions as Major.Minor.Patch. 4. Be aware that patch updates are less likely to cause breaking changes, while minor and major updates may introduce them. 5. Use Terraform commands to check your current version and the latest available versions for both Terraform and its providers. 6. Introduce version constraints in multiple ways, such as equal, not equal, greater/less or equal to, and allowing only the most upright version to increment. 7. Understand breaking changes that may occur during minor version updates and follow upgrade guides provided by Terraform. 8. Upgrade your local Terraform version using different methods like downloading directly, using tfswitch, or tfenv. 9. Develop an upgrade strategy for both Terraform and its providers to ensure a smooth transition between versions. 10. Follow Terraform's GitHub repository and the repository for specific providers to stay updated on new features and changes.
