But it should not be closed. Go, NodeJS or Python I don't use any runtime features to solve it, but rather I just ignore the location/version of the module given in the dependency list and just install whatever one I want, exploiting the fact that (just like in Terraform) the "get" step is separated from the "compile" and "run" steps, and so we can do manual steps in between to arrange for the versions we want. However, the s3 backend docs show you how you can partition some s3 storage based on the current workspace, so each workspace gets its own independent state file. when its expecting: ["name1","name2","name3"]. terraform apply Error: Variables not allowed on vars.tf line 57, in variable "iam_roles_policies_team": 57: aws_iam_policy.test.arn, Variables may not be used here.
