How to set up and validate locally (Terraform state)

Requirements:

• GDK with object storage enabled
• Terraform CLI installed

In your GDK:

1. Create an empty project in your GDK
2. Clone the project locally, and add the following Terraform config in a file named main.tf:

    terraform {
      backend "http" {
      }
    }
   
    resource "local_file" "test" {
        content  = timestamp()
        filename = "${path.module}/foo/test.txt"
    }

3. From your project sidebar in GDK, go to Operate -> Terraform states, and click "Copy terraform init command"
4. Execute the copied command from a terminal in the project directory.
5. Execute terraform plan and terraform apply a few times - successful operations mean the (encrypted) state file is being read and re-saved correctly.

How to set up and validate locally (Secure files)

1. Create a new file, for example:

echo "Hello World" >> ~/Desktop/hello.txt

2. Go to any project in your local GDK. Go to project settings, CI/CD, Secure Files. Click expand, and then click Upload File and upload the file you just created.

3. Once that completes, pull up a rails console and run:

secure_file = Ci::SecureFile.last
secure_file.file.file.read # returns the encrypted contents of the file
Digest::SHA256.hexdigest(secure_file.file.read) == secure_file.checksum # checksums should match
secure_file.file.read # returns the decrypted contents of the file
