Azure Infra Components

Using DC/OS Terraform Infrastructure module to spin up a "cluster"-like infrastrcuture with the following components on Azure:

Resource Group
Network
Network SG
Bootstrap Node
Master Node(s)
Private Nodes(s)

You can view all your components under the Resource Group Created (dcos-$VAR.CLUSTER_NAME). You can use this to delete all resources if needed or your TF state gets lost.

All VMs will use the username dcos_admin user name with the specified ssh key.

Prerequisites:

Terraform less than version 0.12, cloud credentials, and SSH keys:

Installing Terraform.

If you're on a Mac environment with homebrew installed, simply run the following command:

brew install terraform

For help installing Terraform on a different OS, please see here:

Install Azure CLI

You have to install the Azure CLI in order to provide credentials for the terraform provider.

Please checkout the Install the Azure CLI guide to get az installed and running

Ensure your logged into azure

To retrieve credentials please issue

$ az login

the output will show the subscriptions your user has permissions in.

You can insure being logged in by listing your accounts subscriptions

$ az account
[
  {
    "cloudName": "AzureCloud",
    "id": "12345678-abcd-efgh-9876-abc123456789",
    "isDefault": true,
    "name": "Blah Blah Subscription",
    "state": "Enabled",
    "tenantId": "987654321-abcd-efgh-9876-abc123456789",
    "user": {
      "name": "myaccount@azuremesosphere.onmicrosoft.com",
      "type": "user"
    }
  }
]

Ensure Azure Default Subscription

We have to provide the Azure subscription ID. This could be done by exporting ARM_SUBSCRIPTION_ID.

If you do not know your subscription id use az account to see a list of your subscriptions and copy the desired subscription id.

export ARM_SUBSCRIPTION_ID="desired-subscriptionid"

Example:

export ARM_SUBSCRIPTION_ID="12345678-abcd-efgh-9876-abc123456789"

Ensure it is set:

> echo $ARM_SUBSCRIPTION_ID
12345678-abcd-efgh-9876-abc123456789

Usage

Create a main.tf from this repo in your current working directory. Modify any Variable you see fit. See this README for defaults and/or additional variables you can use within your main.tf.
Execute the following after you have auth'd to Azure (see above):

ssh-add ~/.ssh/YOUR_PRIVATE_KEY # adds to key to auth agent
terraform init -upgrade=true
terraform plan -out plan.out
terraform apply plan.out

Check out the Azure Console under your Resource Group.

Note: The main.tf also creates a local inventory file you can use with Ansible. You will just need to provide an ansbile.cfg in the same directory or it will use your default one.

ansible -m ping all -i inventory

Destroy

Be sure that you are auth'd to Azure (see above)
Execute following:

terraform destroy
