Atlantis

Can anyone point me at documentation for installing a more recent version of terraform in a given release's docker image?

Is it as easy as adding the version I want to <https://github.com/runatlantis/atlantis/blob/main/Dockerfile#L115|this line> of the Dockerfile?

Atlantis can do that for you without you having to update the docker image. Please check -&gt; <https://www.runatlantis.io/docs/terraform-versions.html>

There’s a caveat, please check in the end of the doc above:
&gt; The Atlantis <https://github.com/runatlantis/atlantis/pkgs/container/atlantis/9854680?tag=latest|latest docker image> tends to have recent versions of Terraform, but there may be a delay as new versions are released. The highest version of Terraform allowed in your code is the version specified by `DEFAULT_TERRAFORM_VERSION` in the image your server is running.
