I believe the blocker is that to support this feature one would need to implement pre-processing of the configuration. Is that intended behavior? It would be more comfortable to have a backend mapping for all environments what is not implemented yet. if i need to work on another state, i need to change permissions. If the same variable is assigned multiple values, Terraform uses The Terraform configuration must be valid before initialization so that Terraform can determine which modules and providers need to be installed. 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. Are there any chances that we'll have this ability in future versions? 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. Though it's fairly reasonable to want to store the state of an environment in the same account that it's deployed to. Asking for help, clarification, or responding to other answers. Refer to Custom Condition Checks for more details. I feel that many (all?) Sorry you are having an issue with this, but the configuration_aliases argument was added in the 0.15 release. Hands-on: Try the Customize Terraform Configuration with Variables tutorial. If you use a sensitive value as part of an Deploying your terraform to a different account, but using the same backend bucket. Boran. Add support for git tags/branches in module sources, config/module: validate config to load [GH-1439]. What if for some reason we decide to change the company name and company policy mandates that we change the bucket names? if they are present: Files whose names end with .json are parsed instead as JSON objects, with more information on the meaning and behavior of these different types, as well You might also like: Why DevOps Engineers Recommend Spacelift 5 Ways to Manage Terraform at Scale By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. hashicorp/terraform-provider-google#11742. Said another way, TF as it is right now gives me a lot of compile time and runtime errors. Is there any sort of solution besides upgrade to 0.15? But it doesn't make the life easier. app2: ../repo1/foo2.tf You guys are saying to stop promoting terragrunt because they solve artificial problems. Not impossible, but not something that is likely to happen without a major product design effort. I don't really want to use terragrunt, but its the only way I can use variables to populate my backend information. privacy statement. 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. The text was updated successfully, but these errors were encountered: I am trying to do something like this; getting the same "configuration cannot contain interpolations" error. 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. Commenting on #3119 was locked almost 2 years ago saying "We'll open it again when we are working on this". -var-file: Note: This is how Terraform Cloud passes Is there any particular reason behind that? Though it's been closed, and split into two cases, which don't address all the reasons for this, it's more commented then any current open issue. When running terraform plan, it will automatically load any .tfvars files in the current directory. For example, at a bash prompt on a Unix system: On operating systems where environment variable names are case-sensitive, } Terraform matches the variable name exactly as given in configuration, and Terraform 0.12 has an explicit validation check for it to give you better feedback that it's not supported. be unique among all variables in the same module. workspace variables to Terraform. In the example above project1 might not even have staging and project2 might have unit/regression/load-testing/staging phases leading to production release. environment variable values as literal strings, which need only shell quoting, By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. +1 on this. providers = { 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 . This tutorial also appears in: Associate Tutorials (003). the collection or structure itself is not null. might be included in documentation about the module, and so it should be written I am not sure whether this reason is enough to justify using a whole wrapper framework on top of terraform. 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. and lower case letters as in the above example. Connect and share knowledge within a single location that is structured and easy to search.

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. How to extract sensitive output variables in terraform? I'd rather like to pull all my source definitions to the top of a configuration, in a locals definition, so I don't have to go hunting through every file to find/update the string. Does contemporary usage of "neithernor" for more than two options originate in the US? Initializing the backend 73 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"}'. as detailed information about automatic conversion of complex types, see terraform plan Error: Variables not allowed on terraform.tfvars line 1: 1: foo = bar Variables may not be used here. mostly only CI has an assume role that can jump to most accounts, @ecs-jnguyen fix your permissions setup Use Raster Layer as a Mask over a polygon in QGIS. "The id of the machine image (AMI) to use for the server. Have a question about this project? The database username and password are hard-coded. I'm trying to avoid hard-coding module sources; the simplest approach would be: The result I get while attempting to run terraform get -update is. The fix is to add the validation so you get something a bit more clear rather than "error downloading module" I guess. Create a backend yaml file for each and use the one you need, @FernandoMiguel That's exactly what I'm trying to avoid. A variable definitions file uses the same basic syntax as Terraform language can serve as helpful reminders for users of the module, and they 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. 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 hope that you didn't want to store tf-state in one AWS account, but prepare environments in others as somebody asked here. For example, the following configuration: Will cause Terraform to warn you that there is no variable declared "mosse", which can help My use case is very much like @weldrake13's. developer.hashicorp.com/terraform/language/settings/backends/, 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. I was surprised to find such a long and old tread for such a simple issue. +1. Sure, this "works", but it is completely against the very purpose of Terraform, which is to declaratively store a complete picture of resources as code. which will cause Terraform to hide it from regular output regardless of how The Terraform language has a set of operators for both arithmetic and logic, which are similar to operators in programming languages such as JavaScript or Ruby. argument requires a literal value and cannot reference other objects in the 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? When you declare variables in the root module of your configuration, you can terraform plan -var='aad_allowed_tenants=["aasdfad"]' "Variables may not be used here" during terraform init, https://terragrunt.gruntwork.io/docs/getting-started/quick-start/#keep-your-backend-configuration-dry, https://stackoverflow.com/a/69664785/132438, https://www.terraform.io/docs/configuration/locals.html, https://stackoverflow.com/a/61506549/132438, 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. environment variables (set by the shell where Terraform runs) and expression prevent_destroy Variables may not be used here. Please allow variables derived from static values to be used in lifecycle blocks. By default, the OCI Terraform provider automatically retries such operations for up to 10 minutes. @mitchellh, how are compile-tile and runtime differentiated in Terraform?

Seems like a specific instance of a more common problem in Terraform: Concatenating variables. But I got this error. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. +1 I had the same issue, but my problem was the missing quotes around default value of the variable. For convenience, Terraform defaults to interpreting -var and when running terraform env select) it doesn't work. (I've done this several times while debugging, in fact.). Two faces sharing same four vertices issues. Tour Start here for a quick overview of the site . } I write tests for my modules. That setup does have permissions issues but it is still possible. Luckily I have my.terraform directory in the .gitignore. Am I doing something wrong, or is it a bug with the Terraform / AWS Provider? It may not display this or other websites correctly. I agree most of the problems they are solving are artificial. source = "./vpc/customer/${local.orgname}" Can you elaborate? 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]).

Ideally it'd be set up so everything named "project-name-master" would have different permissions that prevented any old dev from applying to it. Have a question about this project? I found no way to prevent accidental deletion of an Elastic Beanstalk Application Environment. Asking for help, clarification, or responding to other answers. If you use Terraform Cloud to provision your resources, your workspace now displays the list of all of the resources it manages. I want admins and automated-ci to be able to specify the local path, allow flexibility to pull from git or filesystem, etc, but this is not possible without allowing interpolation in the source param. @mitchellh elaborating an example to allow the for absolute paths relative to TF-Home. This is where the concept of Terraform Workspaces comes in!! This issue should be opened, or a new one forked off. (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.). Here is an example of a test .tfvars file environment_name = "sandbox" location = "eastus" resource_group_name = "rg-$ {var.environment_name}-$ {var.location}-001" and the associated variables.tf variable "location" {} variable "environment_name" {} on main.tf line 19, in terraform: Is there any documentation which could help folks get better acquainted with how this processing currently works? Can someone please tell me what is written on this score? In a Terraform Cloud workspace. the versions.tf file defines the terraform block. 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. Thanks for listening :). Do not hesitate to share your response here to help other visitors like you. peer-vpc = "vpc-xxxxxxxxxxxxxxxxx" Making statements based on opinion; back them up with references or personal experience. Perhaps in some cases this could be worked around by breaking a configuration into two separate runs, with an initial run creating a remote state that can be consumed by the second run. I believe the blocker is that to support this feature one would need to implement pre-processing of the configuration. value must be convertible to the specified type. Alternative ways to code something like a table within a table? With a better understanding of the current difficulties/blockers, it would be easier to discuss potential solutions. Making statements based on opinion; back them up with references or personal experience. I got it by providing a list variable with following input: [name1,name2,name3] Just as suboptimal as augmenting Terraform with shell scripts or any other solution besides the Terraform developers fixing an issue that's now been open for over 5 years. to your account, https://gist.github.com/steinybot/6d6fed5c27d7eb919a1c939521d57c20. Other kinds of variables in Terraform include The text was updated successfully, but these errors were encountered: I'm trying to avoid hard-coding module sources. Is there a general issue open with Terraform to improve conditional support? It would be nice to understand why this can't work. the module's own source code. See this documentation for more on declaring variables and specifically passing them in via the command line. The reason is simply that it breaks our compile -> semantic check -> execute loop. set their values using CLI options and environment variables. I was just replying to your permissions comment. The use case I have is I wrote a bunch of terraform code to deploy a kubernetes cluster. the environment of its own process for environment variables named TF_VAR_ This is to help in cases where you have provided a variable Switching which infrastructure you're operating against could be as easy as checking out a different git branch. Changing module versions manually is error prone. All Answers or responses are user generated answers and we do not have proof of its validity or correctness. Can we please add var support in the terraform backend file. Terraform will split and store environment state files in a path like 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. Mike Sipser and Wikipedia seem to disagree on Chomsky's normal form. The default value for nullable is true. the root object properties corresponding to variable names: As a fallback for the other ways of defining variables, Terraform searches I need to be able to pass variable. Why don't objects get brighter when I reflect their light back at them? @rootsher With terragrunt just switch the backend to using a generate block and not the terragrunt native backend block. To learn more, see our tips on writing great answers. @lijok @FernandoMiguel I agree the scenario I just described isn't ideal. Terraform variables are useful for defining server details without having to remember infrastructure specific values. Here's an example of how you might set the compartment_id variable using the command-line. Error: Variables not allowed 4 years to fix such a small issue!? Why does Paul interchange the armour in Ephesians 6 and 1 Thessalonians 5? @mitchellh agreement with @jjshoe the original issue of allowing interpolation for the source parameter has not been addressed. But it was suggested only for cases when you work in different AWS accounts. I had the same error message when the first argument was also enclosed in [] (brackets), since it already was a list. I overpaid the IRS. I am using Terraform snowflake plugins. 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? For example, a provider might return the following error even if "foo" is a sensitive value: "Invalid value 'foo' for field". Hi, @opteemister So working with different accounts is normal. What is the etymology of the term space-time? 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.) If I flip to bash, using the exact same terraform.exe, it works. variable "aad_allowed_tenants" { @NickMetz it's trying to do multiple environments with multiple backend buckets, not a single backend. If you're familiar with traditional programming languages, it can be useful to compare Terraform modules to function . and so anyone who can access the state data will have access to the sensitive There is a similar issue in not being able to use interpolation syntax when providing configuration for back ends (say S3 bucket/region). 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. If you're familiar with traditional programming languages, it can be useful to If we cannot have the source set as a variable, could we specify some module-specific config values that would load at runtime? To subscribe to this RSS feed, copy and paste this URL into your RSS reader. It was requested by so many people! sequence of Terraform commands in succession with the same variables. In my code I have a variables module which lives in a git repo and contains all my input variables based on region and environment. ", "The image_id value must be a valid AMI id, starting with \"ami-\".". If your .tfvars file is in another directory you must provide it as a -var-file parameter. A provider error could disclose a value if that value is included in the error message. }, } Why don't objects get brighter when I reflect their light back at them? The chosen direction to implement support for just the version is very limiting. S3 Buckets have an mfa_delete option which is difficult to enable. Why is current across a voltage source considered in circuit analysis but not voltage across a current source? I have you assign it a value. Link to terraform plan documentation. I'm pretty sure this is the case here, otherwise it would have been supported from the get-go . To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Though this might require making such variables immutable? If this gets closed then those following cant view the issue. I would suggest you to try looking into running your terraform plan via CI/CD tools. Variables are not available in this scope? Have you considered fixing your permission setup? . Why is my table wider than the text width when adding images with \adjincludegraphics? I believe this answer has become dated and is now incorrect. a variable definitions file (with a filename ending in either .tfvars How Do I Avoid Repeating A Variable In Terraform?

How can I make the following table quickly? To subscribe to this RSS feed, copy and paste this URL into your RSS reader. value definition. How do philosophers understand intelligence (beyond artificial intelligence)? When using the -var parameter, you should ensure that what you are passing into it will be properly interpreted by HCL. So try InstanceType = "t2.small" 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. hah, this is a powershell problem. If I could store the git URL and a ref tag somewhere in tfvars, for example, that would meet my needs. cidr-octs = "10.7" module "vpc" { Thanks for posting this issue, without it, it would of taken me a long time to figure out whats going on.

This feature was introduced in Terraform CLI v0.13.0. 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. You could checkout terragrunt, which is a thin wrapper that provides extra tools for keeping your configurations DRY, working with multiple Terraform modules, and managing remote state. peer-account = "xxxxxxxxxxxxxx" you spot this mistake. Terraform will still record sensitive values in the state, encrypt = "true" Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. misleading tfvars error message: "Variables not allowed", resource 'monitoring_alert_policy' field 'documentation'. @lorengordon I agree.. this is nonsense.. that and the fact that everytime you pull a whole repository instead of a leaf. instead attempt to parse its value using the same syntax used within variable All Answers or responses are user generated answers and we do not have proof of its validity or correctness. A backend block cannot refer to named values (like input variables, locals, or data source attributes). How to determine chain length on a Brompton? I'm hitting this, too. If we went this route, the only thing that would need to change in Terraform is to switch to a more user-friendly on-disk module representation and to commit not to change it in future versions of Terraform. Thank you, solveforum. ###################### Thought I'd offer up a work around I've used in some small cases. I recommend using different folder paths and wiring up all relative pathing in your TF files. Near the bottom of the file, find the aws_db_instance.database block that defines your database. If you have defined a variable value, but not its corresponding variable {} This is as intended. configuration. Has Hashicorp given any reasoning as to why they're not fixing this? The value assigned to a variable can only be accessed in expressions within Already on GitHub? To set lots of variables, it is more convenient to specify their values in Is it considered impolite to mention seeing a new city as an incentive for conference attendance?

In my case, I wanted to avoid duplicating git::ssh://git@github.com/ across tens or hundreds of files and do something like source = "${var.module_path}//modules/common-vpc". seems my local test env was still running on terraform 0.9.1, after updating to latest version 0.9.2 it was working for me. Using things like basename(path.cwd) also don't work, sadly. From: josephcaxton See https://www.terraform.io/docs/configuration/locals.html. 29: } The given value is not valid for variable "instance_config": list of map of string required. However, the s3 backend docs show you how you can partition some s3 storage based on the current workspace, so each workspace gets its own independent state file. I don't want a backend file and tf vars for each environment. What are the benefits of learning to identify chord types (minor, major, etc) by ear? You say in your question that your variables are in a file variables.tf which means the terraform plan command will not automatically load that file. Existence of rational points on generalized Fermat quintics. I edited my answer to show how to read the backend configuration from a file. type of value that will be accepted as Are you referring to tf plan vs tf apply? This helps our maintainers find and focus on the active issues. from the perspective of the user of the module rather than its maintainer. It was failing as I had not encapsulated a variable with quotes when passing a secret variable from CI/CD. watch out for the types. FIX: rename variables.tf to variables.tfvars. declared as variable names. env:/${var.env}/project/terraform/terraform.tfstate. As a workaround, since we use the S3 backend for managing our Terraform workspaces, I block the access to the Terraform workspace S3 bucket for the Terraform IAM user in my shell script after Terraform has finished creating the prod resources. +, - (subtraction) >, >=, <, <=. values behave the same way as other variables: the last value found overrides 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 You signed in with another tab or window. Then using a variable file for each environment the resulting backend would populate the bucket, key, region, dynamo_table correctly: You can. A lot of us work in multiple aws accounts. @ecs-jnguyen we manage dozens of accounts, with states in some of them. You are using an out of date browser. Hashicorp locked down 3116.
