The source parameter would be: You signed in with another tab or window. 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. FIX: rename variables.tf to variables.tfvars. I'm having problems with this using terratest. [Solved] Ruby on Rails 7 with esbuild generate multiples files .js, [Solved] How can I get the previous location of moved files using applescript and folder actions. 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. You get around that by using terraform init -backend-config so that value is known at the beginning of the lifecycle. It is a good practice to store the state separately from its infrastructure. FIX: rename variables.tf to variables.tfvars within expressions as var., Create a backend yaml file for each and use the one you need, @FernandoMiguel That's exactly what I'm trying to avoid. Cc: Garin Kartes , Comment Can someone please tell me what is written on this score? module configuration blocks, and cannot be Thanks for the save samirshaik. @MichaelDeCorte It's just that it's possible to override the module source parameters with an external file. Yes, there are many ways how to workaround that limitation. Sensitive Resource Attributes. Local Values. I can do this in "provider" blocks as the provider block allows interpolations so I can assume the relevant role for the environment I'm deploying to, however if I also rely on the role being set for the backend state management (e.g. be unique among all variables in the same module. Do you expect some modules to have the same interface, so you can swap these? Tour Start here for a quick overview of the site . } Error: Variables not allowed on <value for var.image_id_map> line 1: (source code not available) Variables may not be used here. It was requested by so many people! imagine if your C code could arbitrarily download new C files during compile/execution. Is it not possible to provide values for bucket and key above through variables file? I believe the blocker is that to support this feature one would need to implement pre-processing of the configuration. A typical tfvars file should contain the variables that you want to pass to Terraform. hashicorp/terraform-provider-google#11742. I believe this answer has become dated and is now incorrect. For convenience, Terraform defaults to interpreting -var and I'd like to do something like (sorry, for the wrapper in Node.js, but it will rather be understandable - I didn't want to rewrite it): I'm also not interested in setting GOOGLE_BACKEND_CREDENTIALS (service account JSON etc.) Link to terraform plan documentation. The value assigned to a variable can only be accessed in expressions within Have you considered fixing your permission setup? Input Variables on the Command Line. Off the top of my head I can think of the following limitations: All of these make writing enterprise-level Terraform code difficult and more dangerous. The same of: #3116 For variables of collection or structural types, such as lists or objects, I know it's been 4 years in the asking - but also a long time now in the replying. It is not compatible with earlier releases of terraform. Why don't objects get brighter when I reflect their light back at them? The type argument in a variable block allows you to restrict the Sci-fi episode where children were actually adults. I am using Terraform snowflake plugins. It looks like: It seems it's not really possible to set nested key/value in the command line argument: backend "s3" { Terraform will still record sensitive values in the state, Also I appreciate this is one resource duplicated, and it would be much worse elsewhere for larger configurations. I expect it would make modules much more maintainable overall. values behave the same way as other variables: the last value found overrides +1 We use terraform modules, the main dev set the default value at "true", that's not my use case :(. 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. Even though the env is set correcty. For more information on quoting and escaping for -var arguments, stackoverflow.com Terraform: "Variables may not be used here" during terraform init Individually, with the -var command line option. This also reduces "noise" in the notification feed for folks following this issue. It may not display this or other websites correctly. I have a git-based module to configure team permissions, and I have ~80 teams. Variables may not be used here. Are variables allowed at all in modules sources? that value. instead attempt to parse its value using the same syntax used within variable Terraform outputs 'Error: Variables not allowed' when doing a plan, https://github.com/hashicorp/terraform/issues/24391, The philosopher who believes in Web Assembly, Improving the copy in the close modal and post notices - 2023 edition, New blog post from our CEO Prashanth: Community is the future of AI. to your account, Variables are used to configure the backend. Feature request. privacy statement. In my case, I wanted to avoid duplicating git::ssh://git@github.com/ across tens or hundreds of files and do something like source = "${var.module_path}//modules/common-vpc". Has Hashicorp given any reasoning as to why they're not fixing this? When nullable is true, null What is the etymology of the term space-time? Reference : https://www.terraform.io/language/settings/backends/configuration. @kokovoj 's use-case, of switching to a different version in a development environment, got me thinking about how that gets solved in other languages. 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. This would let me effectively use modules to run dev & test environments with the same config as prod, while providing deletion protection for prod resources. Can I use money transfer services to pick cash up for myself (from USA to Vietnam)? There is an ongoing issue (#3116) which is currently open but @teamterraform seem to have made that private to contributors only. key = "terraform/state/ops-com" This is not a bad idea but it is very hard to do with the current architecture of how modules work with Terraform. Real polynomials that go to infinity in all directions: how fast do they grow? Find centralized, trusted content and collaborate around the technologies you use most. We conclude the difference as that the variables.tf just declare valid variables and optionally their types, and the tfvars file assigns them values. may assign the value null to the variable. I had something similar , the module was written on version 1.0 and I was using terraform version 0.12. GThoro 2 yr. ago Put t2.small in double quotes. Hands-on: Try the Simplify Terraform Configuration with Locals tutorial. Though it's fairly reasonable to want to store the state of an environment in the same account that it's deployed to. Reply to this email directly, view it on GitHub For example, a provider might return the following error even if "foo" is a sensitive value: "Invalid value 'foo' for field". Same issue experienced here as well, posting my specific error to help future googlers (my output is slightly different due to me wrapping my config with Terragrunt): The following produced the similar error as @steinybot. Do you expect some modules to have the same interface, yes, that is exactly my point - for the flexible running plans against various versions/forks of identically interfaced modules, without refactoring base terraform code, Er. to require a complex value (list, set, map, object, or tuple), Terraform will When Terraform interprets values, either hard-coded or from variables, it will convert them into the correct type if possible. environment variable values as literal strings, which need only shell quoting, It is so funny. You signed in with another tab or window. you assign it a value. Or even something like source yaml_lookup://../lookupfile.yaml which contains module name and source pairs. If a resource attribute is used as, or part of, the provider-defined resource id, an apply will disclose the value. providers = { The text was updated successfully, but these errors were encountered: So the underlying issue is that I forgot to quote the value. Outlook needs password but dialog box disappears, Known HDD user password not working on new Bios. 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. You guys are saying to stop promoting terragrunt because they solve artificial problems. So why make it so we have to employ workarounds to make something this basic work? Questions labeled as solved may be solved or may not be solved depending on the type of question and the date posted for some posts may be scheduled to be deleted periodically. In the last tutorial, you used modules from the Terraform Registry to create a VPC and an EC2 instance in AWS. definitions files, which requires careful attention to the string escaping rules Is it even on your feature/sprint/planning/roadmap or just a backlog item only? Well occasionally send you account related emails. My use-case was inside a module that uses the Github provider. Am I doing something wrong, or is it a bug with the Terraform / AWS Provider? to your account. It's over 4 years since #3116 was opened, I think we'd all appreciate some indication of where this is? and lower case letters as in the above example. @akvadrako You still cannot put variables in backend.conf, which was the initial question. What if for some reason we decide to change the company name and company policy mandates that we change the bucket names? Experiencing this too when I try to pass input a file to plan. The current, beware, if it's for separating environments, workspaces is not suitable for this, as stated in the docs. You are using an out of date browser. 4 years to fix such a small issue!? I want to use ${terraform.workspace} variable in terraform scope. The default value for nullable is true. workspace variables to Terraform. Near the bottom of the file, find the aws_db_instance.database block that defines your database. Error while configuring Terraform S3 Backend. Multiple matching workspaces: Terraform will prompt you to select a workspace from the list. While using existing Terraform modules correctly is an important skill, every Terraform practitioner will also benefit from learning how to create . And will it, if I do this workaround, keep working? To specify individual variables on the command line, use the -var option If I flip to bash, using the exact same terraform.exe, it works. I would also appreciate if Terraform allows variables for specifying "prevent_destroy" values. Terraform CLI defines the following optional arguments for variable declarations: The variable declaration can also include a default argument. privacy statement. We want to archive something similar than @antonosmond. privacy statement. If both the type and default arguments are specified, the given default Setting nullable to false ensures that the variable value will never be How can I make the following table quickly? A provider error could disclose a value if that value is included in the error message. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide, Thanks much! Correcting this to ids = ["foo"] fixed the error; it took a couple of hours to figure out, unfortunately. But otherwise they are very alike, but the first one fails, while the last one doesn't. but from commandline, I try to overwrite it using Passing a the variable is considered to be optional and the default value will be used +1 Can we get an answer as to why this is not supported? The terraform block supports the following arguments: the module's own source code. While it seems like this is being worked on, I wanted to also ask if this is the right way for me to use access and secret keys? I am reviewing a very bad paper - do I have to be nice? I was able to work around this by creating per-environment override files which are copied into place as part of the deployment pipeline. 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! How can I drop 15 V down to 3.7 V to drive a motor? @lorengordon I agree.. this is nonsense.. that and the fact that everytime you pull a whole repository instead of a leaf. i.e. files, but consists only of variable name assignments: Terraform also automatically loads a number of variable definitions files the value for a variable. would love to see interpolations in the backend config. Error: No value for required variable on main.tf line 6: 6: variable "vnet_address_space" { The root module input variable "vnet_address_space" is not set, and has no default value. I found no way to prevent accidental deletion of an Elastic Beanstalk Application Environment. Sorry you are having an issue with this, but the configuration_aliases argument was added in the 0.15 release. Thought I'd offer up a work around I've used in some small cases. I'm getting a similar error. "variables" or "Terraform variables" when it is clear from context what sort of With a better understanding of the current difficulties/blockers, it would be easier to discuss potential solutions.

How to create a storage account for a remote state dynamically? For more information, see I had the same error message when the first argument was also enclosed in [] (brackets), since it already was a list. 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. WHY?!? That setup does have permissions issues but it is still possible. For example, at a bash prompt on a Unix system: On operating systems where environment variable names are case-sensitive, I can't see what the difference is, other than the names and the fact that one of the attributes are a boolean. 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. module "vpc" { Error: Variables not allowed on <value for var.image_id_map> line 1: (source code not available) Variables may not be used here. 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. I'd expect this to be a bit more verbose. 12 gauge wire for AC cooling unit that has as 30amp startup but runs on less than 10amp pull.

GitHub Open on Aug 21, 2019 tomasaschan on Aug 21, 2019 Variable defaults / declarations cannot use conditionals Lifecycle rules cannot use conditionals provider = argument cannot use conditionals Modules cannot have count set If this will be done? 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. Now that we have "environments" in terraform, I was hoping to have a single config.tf with the backend configuration and use environments for my states. We should add validation that this isn't allowed. precedence over earlier ones: Important: In Terraform 0.12 and later, variables with map and object } Interpolations in terraform {} configuration block. The chosen direction to implement support for just the version is very limiting. Thanks again for the feedback! Instead of terraform plan -var 'MyAmi=xxxx' I would expect something more like terraform plan -var 'MyAmi={"us-east-1":"ami-123", "us-east-2":"ami-456"}'. is a valid value for the variable, and the module configuration must always By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Thank you, solveforum. 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 retrieved into the .terraform subdirectory. Am not sure I understood the solution. Teams that make extensive use of Terraform for infrastructure management often run Terraform in automation to ensure a consistent operating environment and to limit access to the various secrets and other sensitive information that Terraform configurations tend to require.. pretty ugly :-). b. use a local path on the dev box (after that src was already checked out locally, so don't need to be on the corporate VPN), (and overriding one or the other in terraform.tfvars) and then. terraform plan Error: Variables not allowed on terraform.tfvars line 1: 1: foo = bar Variables may not be used here. Type constraints are created from a mixture of type keywords and type may treat the entire block as redacted.

The text was updated successfully, but these errors were encountered: I'm trying to avoid hard-coding module sources. variables (used to indirectly represent a value in an FWIW, this is something I wanted to do as well and found wasn't supported. @gsirvas @umeat To archive multiple environment with the same backend configuration it is not necessary to use variables/interpolation .It is expected that is not possible to use variables/interpolation in backend configuration see comment from @christofferh. This name is used to These names are reserved for meta-arguments in Note that the same In my case I was passing the wrong thing to the module: security_groups_allow_to_msk_on_port_2181 = concat(var.security_groups_allow_to_msk_2181, [data.aws_security_group.client-vpn-sg]). sequence of Terraform commands in succession with the same variables. where matches the label given in the declaration block: Note: Input variables are created by a variable block, but you foo1: foo2.tf. (It would also be nice to extend terraform get to be able to handle certain overrides itself, but that is made more complex by the fact that there can be nested modules that have their own dependencies, and so such syntax would probably end up quite complicated if it had to happen entirely on the command line.). Alternative ways to code something like a table within a table? declare an attribute as sensitive, The current method allows plenty of room for human error.
