Provider caching and mirrors in Terraform - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to specify the Terraform provider source.

Terraform

terraform {
  required_providers {
    aws = {
      source = "[1]"
      version = "~> 4.0"
    }
  }
}

💡 Hint

Common Mistakes

Using incorrect source format like 'aws/hashicorp' or 'terraform/aws'.

Forgetting to specify the source at all.

The correct source for the AWS provider is hashicorp/aws. This tells Terraform to use the official AWS provider from HashiCorp.

2fill in blank

medium

Complete the code to configure a provider mirror for Terraform.

Terraform

provider_installation {
  filesystem_mirror {
    path    = "[1]"
    include = ["hashicorp/*"]
  }
  direct {
    exclude = ["hashicorp/*"]
  }
}

Drag options to blanks, or click blank then click option'

A/usr/local/providers

B/mnt/terraform-providers

C/etc/terraform/mirrors

D/var/lib/providers

Attempts:

💡 Hint

Common Mistakes

Using relative paths instead of absolute paths.

Choosing a path that does not exist or is not accessible.

The path should point to the directory where the provider mirror is stored. /mnt/terraform-providers is a common example path.

3fill in blank

hard

Fix the error in the provider installation block to correctly enable the mirror.

Terraform

provider_installation {
  [1] {
    path    = "/mnt/terraform-providers"
    include = ["hashicorp/*"]
  }
  direct {
    exclude = ["hashicorp/*"]
  }
}

Drag options to blanks, or click blank then click option'

Afilesystem_mirror

Bfile_mirror

Cmirror_filesystem

Dmirror

Attempts:

3 left

💡 Hint

Common Mistakes

Using incorrect block names like 'file_mirror' or 'mirror_filesystem'.

Misspelling the block name.

The correct block name is filesystem_mirror. Other names will cause Terraform to fail parsing the configuration.

4fill in blank

hard

Fill both blanks to configure Terraform to use a mirror and fallback to direct installation.

Terraform

provider_installation {
  [1] {
    path    = "/opt/terraform/providers"
    include = ["[2]"]
  }
  direct {}
}

Drag options to blanks, or click blank then click option'

Afilesystem_mirror

Bhashicorp/*

Clocal_mirror

Dterraform/*

Attempts:

3 left

💡 Hint

Common Mistakes

Using incorrect block names like 'local_mirror'.

Using wrong provider patterns like 'terraform/*'.

The block filesystem_mirror is used to specify a local mirror path. The include pattern hashicorp/* matches all providers from HashiCorp.

5fill in blank

hard

Fill all three blanks to configure Terraform with a mirror path, include pattern, and exclude pattern.

Terraform

provider_installation {
  [1] {
    path    = "/data/terraform/providers"
    include = ["[2]"]
  }
  direct {
    exclude = ["[3]"]
  }
}

Drag options to blanks, or click blank then click option'

Afilesystem_mirror

Bhashicorp/*

Dcustom/*

Attempts:

3 left

💡 Hint

Common Mistakes

Using the same pattern for include and exclude incorrectly.

Using wrong block names or patterns.

The filesystem_mirror block defines the mirror path. The include pattern hashicorp/* specifies which providers to use from the mirror. The direct block excludes custom/* providers from direct download, forcing them to use the mirror or fail.
