Terraform Example

Terraform example #

Deploy with CloudShell

Description #

Stack to demostraite capabilities of terraform on simple examples

Setup #

NOTE: If you want to undeploy or update an existing sandbox please proceed directly to Step 3 - Recover

First you need initialize the sandbox configuration. To do this please run the initialization command:

hub stack init

The command will prompt you to enter the GCP project ID and will create initial configuration files and download required components.

Next, to configure sandbox manually run the following command:

hub stack configure

The [Hub CLI] produces a state file after provisioning of sandbox, same as its components, and it must be uploaded to the cloud. For simplicity, we pre-create Cloud DNS Zone and GCS bucket in your GCP project with pre-generated names. This is done during configure command.

Deploy Sandbox #

Once you are done with the configuration, use the following command to deploy the sandbox:

hub stack deploy

To deploy a specific component on the sandbox:

hub stack deploy -c <name-of-the-component>

Parameters #

Each component has a set of parameters (key-value pairs) such as GKE cluster name or number of nodes in a node pool, etc.

Please explore parameters section of the hub.yaml to see what parameters are available. Any default value can be overridden. To get more information on how components are implemented refer to their README files.

To view parameters for the current sandbox run this command:

hub show

Undeploy Sandbox #

To delete the sandbox run this command:

hub stack undeploy

To undeploy a specific component on the sandbox:

hub stack undeploy -c <name-of-the-component>

Recover #

Google Cloud Shell environments are ephemeral, which means any files stored locally on the Cloud Shell machine will be lost when the machine restarts. Luckily, we store sandbox state files in the Cloud, which means, if we lose a local state, we can always recover it from the Cloud.

To recover your sandbox please follow the steps below.

Switch to your current project:

gcloud config set project <project-id>

List all recent sandboxes deployed to your project and find ID of the sandbox you would like to recover:

hub state ls

Initialize your sandbox:

hub stack init <id>

[Hub CLI] will find the location of the state file, download it and prepare configuration files.

After stack recovery undeploy or update your existing stack using corresponding commands.
