Overview

Terraform code for blog post on deploying the request-baskets application on IBM Cloud Code Engine.

Prerequisites

• IBM Cloud API Key
• Terraform installed locally

Getting started

Clone the repository

First, clone the request-baskets terraform repository to your local machine:

```shell
git clone https://github.com/cloud-design-dev/ibmcloud-tf-ce-request-baskets.git
cd ibmcloud-tf-ce-request-baskets
```

Set Terraform environment variables

Copy the terraform.tfvars.example file to terraform.tfvars, open it in a text editor and set the following variables:

• ibmcloud_api_key: Your IBM Cloud API key.
• ibmcloud_region - The IBM Cloud region where you want to deploy the resources. Default is us-south.
• existing_resource_group - The name of the resource group where you want to deploy the resources.
• existing_postgres_instance - The name of the existing PostgreSQL instance where you want to store the requests.
• project_owner - Owner to associate with the project. Will be used as a tag for the resources.

Initialize Terraform

Run the init command to initialize Terraform in the directory and download the required providers and modules:

```shell
terraform init
```

Generate the Terraform plan

Run the following command to generate a Terraform plan and save it to the file default.tfplan:

```shell
terraform plan -out default.tfplan
```

Apply the Terraform plan

Run the following command to apply the Terraform plan, create our project, and deploy the application:

```shell
terraform apply default.tfplan
```

The Code Engine project will take a few minutes to get created. Once the project is created, Terraform will move on to deploying our application using the request-baskets container image and add our PostgreSQL connection details to the running instance via environmental variables.

Clean up

To clean up the resources created by Terraform, run the following command:

```shell
terraform plan -destroy -out destroy.tfplan
terraform apply destroy.tfplan
```
