tfenv VS terraform-switcher

You'll need the correct version of Terraform (the version of Terraform used for apply can be found in terraform_version at the beginning of the .tfstate file), to switch between versions I recommend tfenv.

For almost four years I'd been using a Macbook as my main work machine. One quality of life tool I'd gotten used to was tfenv, a lovely little tool for managing terraform versions & quickly switching between them.

For example terraform state files often have non backwards compatible changes. You should consider using something like tfenv so everyone on your team has identical versions of terraform.

I'm using the tool tfenv to manage Terraform versions. Other tools can do that. You can use asdf, too. I saw that asdf can do more than manage Terraform versions.

Documentacion TFENV

git clone https://github.com/tfutils/tfenv.git ~/.tfenv export PATH="$HOME/.tfenv/bin:$PATH" # install to appropriate shell startup file, e.g. $HOME/.bashrc echo 'export PATH="$HOME/.tfenv/bin:$PATH"' >> ~/.profile

‍TFSwitch is a CLI tool that allows easy switching between different Terraform versions, simplifying workflows in environments where multiple Terraform versions are used.

tfswitch might help with particular issue of terraform versioning:

Even then some versions of terraform providers are not compatible with M1 macs. Docker would help with that probably, but so can: https://github.com/kreuzwerker/m1-terraform-provider-helper

Perhaps these sort of issues support the benefits of per-module docker images?

My approach is to change the version in the version.tf file, install the new version using tfswitch (https://tfswitch.warrensbox.com/) and execute a plan. If infrastructure matches the configuration I will asume there are no breaking changes...

Also, an excellent tool can help with fast switching between different Terraform versions while you’re experimenting — tfswitch.

It was easy. I didn't use terraform-version files like you, but there are similar ways to automatically switch versions. https://github.com/warrensbox/terraform-switcher
