How to determine chain length on a Brompton? @danieldreier given that Hashicorp has acknowledged this issue as a "known limitation" based on your June 12, 2020 comment, is the company able to provide a standard or recommended workaround to address this? In it, the required_providers block specifies the provider and provider version required by the configuration. locals { the last value it finds, overriding any previous values. All Answers or responses are user generated answers and we do not have proof of its validity or correctness. Multiple matching workspaces: Terraform will prompt you to select a workspace from the list. Has Hashicorp given any reasoning as to why they're not fixing this? } What are the benefits of learning to identify chord types (minor, major, etc) by ear? I also would like to be able to use interpolation in my backend config, using v 0.9.4, confirming this frustrating point still exists.

The default value for nullable is true. I overpaid the IRS. key = "terraform/state/ops-com" BR, I have a git-based module to configure team permissions, and I have ~80 teams.

Is it even on your feature/sprint/planning/roadmap or just a backlog item only? or .tfvars.json) and then specify that file on the command line with By default, the OCI Terraform provider automatically retries such operations for up to 10 minutes. Or some sort of cli option --source_overrides=something.yaml The value is saved in the state, and warns if anything is different to the last run. Can someone with the inner knowledge of this "feature" work please step up and give us some definitive answers on simple things like: Thanks for your work - Hashicorp - this tool is awesome! the versions.tf file defines the terraform block. terraform The terraform block is used to configure how Terragrunt will interact with Terraform. For example, the following configuration: Will cause Terraform to warn you that there is no variable declared "mosse", which can help +1. And indeed, if you comment out the variable reference in the snippet above, and replace it with prevent_destroy = false, it works - and if you then change it back it keeps working. The Terraform configuration must be valid before initialization so that Terraform can determine which modules and providers need to be installed. The name of a variable can be any valid identifier and no special quoting for Terraform. #30937. values in cleartext. Reply-To: hashicorp/terraform The problem is that I want to assume an AWS role based on the environment I'm deploying to. Terraform supports many command-line parameters, one of which is the -var parameter which allows you to set the value of a variable when you run Terraform. Can terraform backend fields be accessed as variables? I have the same problem i.e. How to determine chain length on a Brompton? They are similarly handy for reusing shared parameters like public SSH keys that do not change between configurations. It looks like: It seems it's not really possible to set nested key/value in the command line argument: backend "s3" { WHY?? So in addition to giving the backend bucket name and key in tfvars, I should also create an TF_CLI_ARGS_init environment variable? I hope that you didn't want to store tf-state in one AWS account, but prepare environments in others as somebody asked here. value meant for a variable declaration, but perhaps there is a mistake in the Error: Variables not allowed I am asking this question WHY? If you use Terraform Cloud to provision your resources, your workspace now displays the list of all of the resources it manages. Obviously, quoting the value results in provider configuration not been passed properly into the module. A provider can also This is where the concept of Terraform Workspaces comes in!!

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. WHY? Terraform's usual syntax for Variables may not be used here. Having such feature is particularly useful if you want to test new module version which is located in some feature branch in another (shared) repo, you then have to edit all paths to module manually and re-init anyways. Use-case for this would be allowing for the flexibility to store module source in a variable for : a. module source pointing at a corporate source control behind a corporate VPN, OR Yeah, we've been using the Terrafile approach (see my comment above) it works pretty well but it forces us to use a wrapper script, I think that the Terrafile pattern should be supported by Terraform. My use case is very much like @weldrake13's. You cannot use variables in variable files it will cause cyclic dependency. A backend block cannot refer to named values (like input variables, locals, or data source attributes). This name is used to @akvadrako different variables. @ecs-jnguyen we manage dozens of accounts, with states in some of them. module "iam" { It is also important that the resource plans remain clear of personal details for security reasons. Using locals to concatenate should fix it. On that note, @samirshaik thank you for the workaround, worked like a charm. I need to be able to pass variable. cidr-octs = "10.7" You can only declare stuff. If this is the case, I would like to share my experience as a user has never built confidence in tf apply succeeding if tf plan succeeds. The need to set lifecycle properties as variables is required in a lot of production environments. Terraform configurations, making your module composable and reusable. Use pre-installed Terraform plugins instead of downloading them with terraform init. peer-account = "xxxxxxxxxxxxxx" You are using an out of date browser.

Can we please add var support in the terraform backend file. I don't want a backend file and tf vars for each environment. seems my local test env was still running on terraform 0.9.1, after updating to latest version 0.9.2 it was working for me.

If you have found a problem that seems similar to this, please open a new issue and complete the issue template so we can capture all the details necessary to investigate further. How can I detect when a signal becomes noisy? Local Values.

Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide, For some reason, this failed in Powershell with error as. I'm hitting this, too. 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). commentary for module maintainers, use comments. Feature request. If a resource attribute is used as, or part of, the provider-defined resource id, an apply will disclose the value. Not the answer you're looking for?

Some special rules apply to the -var command line option and to environment For example, in a Unix-style shell: However, if a root module variable uses a type constraint I'm getting a similar error. when running terraform env select) it doesn't work. We should add validation that this isn't allowed. Can't we pass the bucket and key names for backend through. This is of course not as convenient as creating everything in one step using directly-referenced modules, but maybe it's a reasonable workaround for some situations in the mean time. The configuration_aliases block was introduced in 0.15. Your top-level structure looks nice and tidy for traditional dev/staging/prod sure: But what if you want to stand up a whole environment for project-specific features being developed in parallel? module "vpc" { Have a question about this project? Though it's fairly reasonable to want to store the state of an environment in the same account that it's deployed to. of the above use cases could be resolved by adding${path.root} to the list of allowed local module source prefixes. If we cannot have the source set as a variable, could we specify some module-specific config values that would load at runtime? You signed in with another tab or window.
