I have a module `./modules/monitoring` ```auto / +- modules | +- monitoring | + backend.tf | + main.tf | + variables.tf +- subdir1 | + main.tf | ... +- subdir2 | + main.tf | ... ... ``` It contains the following `backend.tf` ```auto terraform { required_providers { kubectl = { source = "gavinbunney/kubectl" version = "~>1.14.0" } } } ``` which contains a [kubectl\_manifest](https://registry.terraform.io/providers/gavinbunney/kubectl/latest/docs/resources/kubectl_manifest)-resource: ```auto resource "kubectl_manifest" "monitoring_alertmanagerconfig_project" { ... ``` I use the module as follows: ```auto module "monitoring" { source = "../modules/monitoring" clusterid = rancher2_cluster.cluster.id project_namespaces = local.project_namespaces namespaces = local.namespaces } ``` `tf plan`gives me this error ```auto │ Error: failed to read schema for kubectl_manifest.monitoring_alertmanagerconfig_project in registry.terraform.io/hashicorp/kubectl: failed to instantiate provider "registry.terraform.io/hashicorp/kubectl" to obtain schema: unavailable provider "registry.terraform.io/hashicorp/kubectl" ``` ---

Hi @papanito, It sounds like your other modules are missing their declaration that they depend on `gavinbunney/kubectl`. For backward compatibility with modules that were written before Terraform supported third-party providers Terraform assumes that any undeclared dependency is for an official provider (in the `hashicorp/` namespace), but modern Terraform modules should always specify all of the providers they depend on. If I’ve guessed correctly what the problem is then the solution would be to write a similar `required_providers` block in each module. However, shared modules should not typically constrain the upper bound in their version constraints, because that tends to make things complicated if you want to upgrade later (you’ll need to update all of the modules at once) and so I would recommend setting the shared modules to use only `>=`-style constraints (instead of `~>` constraints) and to specify the minimum provider version that you know the provider is compatible with. (Version constraints are intended for specifying provider version compatibility, not for specifying version _selections_.) ---

The affected dependency seems clearly - at least based on the error - the one I explicitly declared. ---

In meanwhile I got it working. I am not entirely sure what fixed the issues, cause the `backend.tf` did not change. Maybe related to my tries to do a `terraform init -reconfigure` and/or `terraform init -upgrade`. I may post more details once I understand what changed ---

In the filesystem tree you shared there are three modules: - `modules/monitoring` - `subdir1` - `subdir2` When I say “all modules” I mean all three of those, and any other directories that have `.tf` files in them. Any directory with at least one `.tf` file is a Terraform module. ---

> [@apparentlymart](#): > > When I say “all modules” I mean all three of those, and any other directories that have `.tf` files in them. Any directory with at least one `.tf` file is a Terraform module. Got it. They all have the providers properly defined. I initially had everything in each module, and then moved “monitoring” to a reusable module.
