multizone-app-cluster

A Terraform configuration for deploying a app on multi zone cluster

This configuration template is tested for IBM Cloud Provider version v0.11.2

Usage with Terraform Binary on your local workstation

You will need to setup up IBM Cloud provider credentials on your local machine.

Prerequisite

  1. Download Terraform binary. Unzip it and keep the binary in path ex- /usr/local/bin.
  2. Download IBM Cloud Provider Plugin. Unzip it and keep the binary in path in the same directory where you placed Terraform binary in previous step. You can also build the binary yourself. Please look into documentation.

To run this project locally execute the following steps:

  • You can override default values that are in your variables.tf file.
  • terraform apply: this will create actual infrastructure
  • terraform destroy: this will destroy all infrastructure which has been created

Setting up Provider Credentials

To setup the IBM Cloud provider to work with this example there are a few options for managing credentials safely; here we'll cover the preferred method using environment variables. Other methods can be used, please see the Terraform Getting Started Variable documentation for further details.

Environment Variables using IBMid credentials

You'll need to export the following environment variables:

  • TF_VAR_bluemix_api_key - your Bluemix api key
  • TF_VAR_private_vlan_id - provide private vlan id
  • TF_VAR_public_vlan_id - provide public vlan id

On OS X this is achieved by entering the following into your terminal, replacing the <value> characters with the actual values (remove the <>:

  • export TF_VAR_bluemix_api_key=<value>
  • export TF_VAR_private_vlan_id=<value>
  • export TF_VAR_public_vlan_id=<value>

Variables

Variable Name Description Default Value
region eu-de
datacenter ams03
machine_type u2c.2x4
isolation public
private_vlan_id
public_vlan_id

Output

Upon completion, terraform will output the url of the application, e.g.:

app_url_1 = "<url>"

app_url_2 = "<url>"

Use this url to access your application
