Deployment is 100% automated for us, and if the dev teams need to make a change to a resource, or remove it then that change would have gone through appropriate testing and peer review before being checked into master and deployed. Initializing the backend 73 It would be nice to understand why this can't work. If you provide values for undeclared variables defined in a file In Terraform 0.10 there will be a new setting workspace_key_prefix on the AWS provider to customize the prefix used for separate environments (now called "workspaces"), overriding this env: convention. Is it still waiting on the proposal mentioned in this comment, #4149 ? (Which is fine for my use case; not sure about others.). I had the same error message when the first argument was also enclosed in [] (brackets), since it already was a list. on line 1: Use a -var or -var-file command line argument to provide a value for this variable. +1 To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Although the sole Terraform documentation prescribe such usage, see Providers Within Modules - Configuration Language - Terraform by HashiCorp (in the end of the section, right before the next section starts). Setting a variable as sensitive prevents Terraform from showing its value in The source parameter would be: Boran. Thanks for your interest in this issue! Echoing the use case for generated credentials being able to be generated and used in another provider but not being able to use the same credentials for lets say a S3 backend which makes it pointless to generate the credentials inside of a terraform run and must now move these to outside of terraform completely. 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. +1 for this. The need to set lifecycle properties as variables is required in a lot of production environments. So instead this worked for me: security_groups_allow_to_msk_on_port_2181 = concat(var.security_groups_allow_to_msk_2181, [data.aws_security_group.client-vpn-sg.id]). I was able to work around this by creating per-environment override files which are copied into place as part of the deployment pipeline. You must log in or register to reply here.

Can you close, please? In the case of production, this will decrease the risk of sensitive data leakage from the state if production access credentials will be compromised. Microservices are better versioned and managed discretely per component, rather than dumped into common prod/staging/dev categories which might be less applicable on a per-microservice basis, each one might have a different workflow with different numbers of staging phases leading to production release. Experiencing this too when I try to pass input a file to plan.

If your .tfvars file is in another directory you must provide it as a -var-file parameter. See the terraform documentation on partial configuration for more details. You say in your question that your variables are in a file variables.tf which means the terraform plan command will not automatically load that file. One very specific complexity with this is that currently modules need to be pre-fetched using terraform get prior to terraform plan, and currently that command does not take any arguments that would allow you to set variables.

This is to help in cases where you have provided a variable Have you considered fixing your permission setup? This is as intended. null value as a module input argument will override any default value. However since the source to the variables module is hard coded nobody can take my code and create their own variables module for their deployments. Example here is a module for gcloud sql instance, where obviously in production I want to protect it, but more ephemeral environments I want to be able to pull the environment down without editing the code temporarily. We do interpolation that way which works just fine. The text was updated successfully, but these errors were encountered: So the underlying issue is that I forgot to quote the value. .

Either way, my vote for unblocking this capability (understanding it isn't simple, given current architecture) stems from wanting the ability (as a user) to choose whether or not a variable in the module source is a good decision for my code.

Our powershell wrapper does so many things to over come terraform restrictions, we cant use terraform without, basically we did something like the guys in terragrunt did, plus many more addons on it, i cant understand how somebody can even use terraform as is out of the box without some interpolation in those missing places.. anyhow, i really hope hashicorp will decide to change some parts of the product, because it is really constricting, some of those things should have been thought of much before. But I got this error. Terraform reads all of your *.tf files (under your working directory) as one giant script during run time, so you only need to declare your variables once. 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.
