Kubernetes the Hard Way uses Google Cloud for its labs. Since we're using Azure in this repository, there will be some differences. These differences are detailed in this delta.

Create a new service principal

You'll need to create a new Azure service principal before you can run the commands below. To do that, run this az command:

az login -t $YOUR_TENANT_ID # Log in through the web browser when prompted.
az ad sp create-for-rbac -n "tthw-sp" --role Owner

NOTE: If your subscription's management group does not allow service principals with Owner roles, try creating a service principal as a contributor instead:

az ad sp create-for-rbac -n "kthw-sp" --role Contributor

You'll get a blob like the one shown below:

{
  "appId": "your_appId",
  "displayName": "khtw-sp",
  "name": "http://kthw-sp",
  "password": "your_password",
  "tenant": "your_tenant"
}

Copy and save into a new file called $HOME/.azure_credentials.

Treat this file like the key to your house (or some other possession you deeply care about). Don't distribute it with anyone!

Once done, you can log into Azure using this service principal with the command below:

az login --service-principal -u $(jq -r .appId ~/.azure_credentials) \
  -p $(jq -r .password ~/.azure_credentials) \
  -t $(jq -r .tenant ~/.azure_credentials)

Create a resource group for our labs

We'll also need a resource group to hold all of the resources we'll be creating for our labs. Run the command below to create that:

az group create --name kubernetes
