But it doesn't make the life easier. Input variables are like function arguments. Sci-fi episode where children were actually adults. 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 would be called acmecorp.tf, we would just copy this module and renamed it to loonytoons.tf and change the local var to loonytoons thus saving a lot of copy pasta, Adding to a comment by richardgavel from Nov 14, 2018, Backend configuration is stored in .terraform/terraform.tfstate, so store module sources in there and require re-init if those change, i.e something like module.cluster1.app -> source="github.com/example/example".

Because when I try doing the same like this: Create a file named backend.tfvars with content: Specify this file name in a command line option to the terraform command: 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. 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. Our modules need to be capable of having lifecycle as variables. briefly describe the purpose of each variable using the optional 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. If you're familiar with traditional programming languages, it can be useful to compare Terraform modules to function . I thought im fairly resourceful when it comes to terraform, but lately all these new versions popping up every 2 seconds, and the tons of changes are confusing the hell out of me. When I gave backend bucket name and key in .tfvars, I got the error as I explained in my question. Terraform will still record sensitive values in the state, Same thing for me. Works great. 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.

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. We were able to get around this by using backend-config when initializing the Terraform project as shown below. Sure I will post in SO. ###################### At the moment we use multiple environments prod/stage and want to upload tfstate files to S3.

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)). Function calls not allowed on provider.tf line 9, in terraform: 9: bucket = element(local.BUCKET_NAME, 1) Functions may not be called here. The example below checks whether the AMI ID has the correct syntax. Another example as to why this is beneficial: `####################### Global value ####################### I don't find this ideal, but at least I can easily switch between environments and create new environments without having to edit any terraform. My module supports figuring out if the user specified an existing repo or the repo needs to be created. definition, you may get an error or warning depending on how you have provided No, can be done from the inside as well. when running the terraform plan and terraform apply commands: The above examples show appropriate syntax for Unix-style shells, such as on The Terraform configuration must be valid before initialization so that Terraform can determine which modules and providers need to be installed. 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. The configuration_aliases block was introduced in 0.15. The default value for nullable is true. @lorengordon I agree.. this is nonsense.. that and the fact that everytime you pull a whole repository instead of a leaf.

You get around that by using terraform init -backend-config so that value is known at the beginning of the lifecycle. } +1 I also think that the gained flexibility would outweigh the disadvantages. In variable definitions ( .tfvars) files, either specified on the command line or automatically loaded. @mitchellh agreement with @jjshoe the original issue of allowing interpolation for the source parameter has not been addressed. @kolesaev how your suggestions relates to the original request of possibility to use variables in terraform backend? That means they need to be provided when you run terraform init, not later when you use the backend with commands like terraform apply. Not the answer you're looking for? the versions.tf file defines the terraform block. Well occasionally send you account related emails. Ideally I'd want my structure to look like "project/${var.git_branch}/terraform.tfstate", yielding: Now, everything you find for a given project is under its directory so long as the env is hard-coded at the beginning of the remote tfstate path, you lose this flexibility. So why make it so we have to employ workarounds to make something this basic work? If you use Terraform Cloud to provision your resources, your workspace now displays the list of all of the resources it manages. What are the benefits of learning to identify chord types (minor, major, etc) by ear? 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 a resource attribute is used as, or part of, the provider-defined resource id, an apply will disclose the value. which will cause Terraform to hide it from regular output regardless of how So with all of this said, perhaps Terraform could just be a little more transparent about where it looks for modules and embrace the idea that terraform get just installs the default module locations, but it's fine to manually install from other locations, or even to write your own separate tool to install from wherever you want. In a Terraform Cloud workspace. configuration. argument requires a literal value and cannot reference other objects in the By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. But you should also create a variable.tf file also to define the variable type -. I am not sure whether this reason is enough to justify using a whole wrapper framework on top of terraform. hah, this is a powershell problem. Terraform obscures this ability a little by storing the local modules in a directory named after the MD5 hash of the module name under the .terraform directory, so it's harder to recognize which one is which by eye but you can, if you locate the right one, install it from a different source or modify it in-place. Using separate config file during each TF run is not useful at all. This happens for resource types where I have Two faces sharing same four vertices issues. Find centralized, trusted content and collaborate around the technologies you use most. DB Safety feature and GCP opta destroy + config upload. Though it's fairly reasonable to want to store the state of an environment in the same account that it's deployed to.

Agreed, issue has been open since 2017 ? can serve as helpful reminders for users of the module, and they really appreciate your help - Eva. 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. May 13, 2021 at 6:08. (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.). I also posted the same question to stackoverflow. 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. Connect and share knowledge within a single location that is structured and easy to search.
