Same behavior if instead of using the toset function in the for_each i change it to a for loop, like for_each = {for k, v in var.group1 : k => (v)}. It applies correctly, but in the second apply it tries to remove the assignations. You can define the group1 variable as a set instead of a list and try with that.Basic Syntax. count is a meta-argument defined by the Terraform language. It can be used with modules and with every resource type. The count meta-argument accepts a whole number, and creates that many instances of the resource or module. Each instance has a distinct infrastructure object associated with it, and each is separately created ...3. Inside a configuration block in Terraform, omitting an optional argument and setting that argument to null are equivalent.

So the instance_count variable would also work using a string ("2") instead of a number (2).We recommend using the most appropriate type in variable definitions to helps users of your configuration know the appropriate data type to …An object is a nice flat structure to build an abstraction. A list of objects provides declarative transforms to organize data into the structure we want for building other resources and modules. Consider these transforms resulting in the same collection types from the map of maps example. locals {. list_of_objects = [.References to Named Values. Hands-on: Try the Create Dynamic Expressions tutorial. Terraform makes several kinds of named values available. Each of these names is an expression that references the associated value. You can use them as standalone expressions, or combine them with other expressions to compute new values.We use cookies and other similar technology to collect data to improve your experience on our site, as described in our Privacy Policy and Cookie Policy.Basic Syntax. count is a meta-argument defined by the Terraform language.

The Terraform state is written to the key path/to/my/key. Note that for the access credentials we recommend using a partial configuration.A dynamic block acts much like a for expression, but produces nested blocks instead of a complex typed value. It iterates over a given complex value, and generates a nested block for each element of that complex value. The label of the dynamic block ( "setting" in the example above) specifies what kind of nested block to generate.values = [random_string.origin_secret[0].result] Right now it just returns a list with 4 maps (the conditions only) rather than the list of two listeners each with two conditions. │ The true and false result expressions must have consistent types. The 'true' tuple has length 4, but the 'false' tuple has length 2.You can't use interpolation in a tfvars file.

Each validation requires a condition argument, an expression that must use the value of the variable to return true if the value is valid, or false if it is invalid. The expression can refer only to the containing variable and must not produce errors.Processing and Planning Consequences. The depends_on meta-argument instructs Terraform to complete all actions on the dependency object (including Read actions) before performing actions on the object declaring the dependency. When the dependency object is an entire module, depends_on affects the order in which Terraform processes all of the resources and data sources associated with that module.2. Yes this is possible, you need to use the for expression in Terraform to achieve this though, the for loop converts the list of objects into a value in which Terraform can loop over using for_each, without the for expression, Terraform cannot loop over the list of objects because there is no key value for Terraform to reference.iterate over the list of ebs_block_devices, tracking the index (like enumerate() in Python, or each.with_index in Ruby) get the corresponding element from the list of mount_points; add these to a resultant map.

We can discard those and fix the value accordingly: for_each = var.rules. The second issue is that your temporary lambda iterator variable in a dynamic block is the ...So I resolved this myself. You can actually manually update a state file to add outputs to a module. Key points are: When using terraform_remote_state, module outputs are only available if they exist in the root module. You can't remotely reference an output in a module nested in the root module. Referencing outputs as vars isn't hugely intuitive.c. apparentlymart October 3, 2022, 3:21pm 3.
