I, on the other hand, need to authenticate myself to GCS. Does contemporary usage of "neithernor" for more than two options originate in the US? Adding required parameters from the command line, in the absence of being able to actually using variables within backend, is simply suboptimal. A local value assigns a name to an expression , so you can use the name multiple times within a module instead of repeating the expression. so while I'm bummed that this doesn't work, I understand that I shouldn't expect it to. <, With workarounds being provided and they intentionally made it this way, not likely we will see parameters in the source line.

In this case, when dealing with review/staging deployment, many people may have admin access to the infra but they will not break the state. be unique among all variables in the same module. Have you considered fixing your permission setup? Perhaps it's better to just give accross account access to the user / role which is being used to deploy your terraform. variable "aad_allowed_tenants" { In this case with above backend definition leads us to this Error: Is there a workaround for this problem at the moment, documentation for backend configuration does not cover working with environments. But otherwise they are very alike, but the first one fails, while the last one doesn't. Is Hashcorp looking to resolve this issue? I agree most of the problems they are solving are artificial. so the required environment variable name will usually have a mix of upper This also reduces "noise" in the notification feed for folks following this issue. Making statements based on opinion; back them up with references or personal experience. It's not pretty but it works, and is hidden away in the module for the most part: Module originated prior to 0.12, so those conditionals could well be shortened using bool now. Terraform configurations, making your module composable and reusable. Did Terraform change Partial Configuration? Is it not possible to provide values for bucket and key above through variables file?

On Sat, Oct 20, 2018, 10:17 AM Matthew Tuusberg ***@***. Please, this is really frustrating. Has Hashicorp given any reasoning as to why they're not fixing this? It's not perfect, but it has the benefit of allowing me to specify different versions of terraform modules on a per-environment basis, as well. Error: No value for required variable on variables.tf line 1: 1: variable " foo " { The root module input variable " foo " is not set, and has no default value.

Thanks for contributing an answer to Stack Overflow! is a valid value for the variable, and the module configuration must always null within the module. variables (used to indirectly represent a value in an The only way for now is to use a wrapper script that provides env variables, unfortunately. Funny thing is when I do it with another variable, that has the same structure, I don't get this error. If present, When Terraform interprets values, either hard-coded or from variables, it will convert them into the correct type if possible. This includes specifying where to find the Terraform configuration files, any extra arguments to pass to the terraform CLI, and any hooks to run before or after calling Terraform. to assign complex-typed values, like lists and maps. sequence of Terraform commands in succession with the same variables.

I've knocked up a bash script which will update TF_VAR_git_branch every time a new command is run from an interactive bash session. privacy statement. Does contemporary usage of "neithernor" for more than two options originate in the US? If you provide values for undeclared variables defined as environment variables source = "./iam/customer/${local.orgname}" bucket = "ops" Works great. Can someone please tell me what is written on this score? 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.By the time plan is running, Terraform is just thinking about the module name and paying no attention to the module source, since the module is assumed to already be . For many features being developed, we want our devs to spin up their own infrastructure that will persist only for the length of time their feature branch exists to me, the best way to do that would be to use the name of the branch to create the key for the path used to store the tfstate (we're using amazon infrastructure, so in our case, the s3 bucket like the examples above). JavaScript is disabled. Function calls not allowed on provider.tf line 9, in terraform: 9: bucket = element(local.BUCKET_NAME, 1) Functions may not be called here.

I'm having problems with this using terratest. Right now we also met the same issue. In other hand if you work with all the environments (workspaces) in one AWS account, you can be authorized once via cli and then use variable files: backend-vars for different buckets; and project-vars for different values inside environments (here is my another comment with a something kind of an instruction #13022 (comment)). @mitchellh - It would be great if hashicorp could re-look at this. The rationale to disallow this so that intelligent people can't download random modules is the same as not having a division operator as somebody may decide to divide by zero one day. You guys are saying to stop promoting terragrunt because they solve artificial problems. In my example you could still use terraform environments to prefix the state file object name, but you get to specify different buckets for the backend. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. of the variable and what kind of value is expected. @rootsher With terragrunt just switch the backend to using a generate block and not the terragrunt native backend block. Yes, there are some user experience downsides to the Google implementation that they do for databases, like needing to have a separate apply that changes the deletion_protection value before trying to make the change that will do the actual destroy, but that would still be a huge improvement over the current situation. Find centralized, trusted content and collaborate around the technologies you use most. ###################### Input variables let you customize aspects of Terraform modules without altering How do philosophers understand intelligence (beyond artificial intelligence)? region = "us-westt-1" Does contemporary usage of "neithernor" for more than two options originate in the US? It is so funny. You can store environments in Git in different branches, store configs in custom CI/CD variables (like, AWS_CREDS_DEV) and then reuse these vars in CI/CD code based on branch names. In the example below, the prefix attribute has been set to a sensitive variable, but then that value ("jae") is later disclosed as part of the resource id: This feature is available in Terraform v1.1.0 and later. What is the etymology of the term space-time? be declared but not used in all configurations that might be run. env = "production" Within the module that declared a variable, its value can be accessed from We notice that terraform raises a warning about assigning a value to an undeclared variable.

I wanted to extract these to variables because i'm using the same values in a few places, including in the provider config where they work fine. compare Terraform modules to function definitions: Note: For brevity, input variables are often referred to as just Same thing for me. The above mechanisms for setting variables can be used together in any I found no way to prevent accidental deletion of an Elastic Beanstalk Application Environment. terraform init -backend-config=backend.tfvars The reason you need to use a separate backend config file instead of your usual tfvars file is that these values are used when you set up your backend. This section does When Tom Bombadil made the One Ring disappear, did he put it into a place that only he had access to? I agree with that statement. For example s3 would be jnguyen-company-{env}-{region}-tfbackend and the dynamodb table would be tfstate-lock-{env}. I was hoping to do the same thing as described in #13603 but the lack of interpolation in the terraform block prevents this. Sensitive Data in State.
