Terraform NWS module friends

This is a hello-world example for NWS cloud services.

Terraform install

• Download terraform binary for your platform from NWS CDN here
• Install with: sudo mv ./terraform /usr/local/bin/
• Make a symlink to improve user experience: sudo ln -s /usr/local/bin/terraform /usr/local/bin/tf

Deploying the module

• Init module with

cd examples/hello
tf init
tf plan

• Inspect terraform output and apply changes with: tf apply -auto-approve

Update deployment

• Inspect deployed infrastructure with: tf show

• Update infra, for example, set Vasya's age to 25.

• Run plan to obtain an infra diff: tf plan. You should look like below:

Terraform will perform the following actions:

  # module.friends.nws_demo_friends.friends will be updated in-place
  ~ resource "nws_demo_friends" "friends" {
      ~ friends = [
          ~ {
              ~ age  = 23 -> 25
                name = "Vasya"
                # (1 unchanged attribute hidden)
            },
            # (1 unchanged element hidden)
        ]
        id      = "8bd9f27b-8849-43e8-8966-027aba6d4cbe"
        name    = "Ivan"
    }

Plan: 0 to add, 1 to change, 0 to destroy.

• Apply updated changes with: tf apply -auto-approve

• Inspect updated infra with: tf show

# module.friends.nws_demo_friends.friends:
resource "nws_demo_friends" "friends" {
    friends = [
        {
            age  = 19
            name = "Ann"
            sex  = "F"
        },
        {
            age  = 25        <----- the age was updated
            name = "Vasya"
            sex  = "M"
        },
    ]
    id      = "8bd9f27b-8849-43e8-8966-027aba6d4cbe"
    name    = "Ivan"
}


Outputs:

id = "8bd9f27b-8849-43e8-8966-027aba6d4cbe"
name = "Ivan"

Remove deployment

• Destroy deployment with: tf destroy -auto-approve
• Make sure that the infra is empty: tf show
