Environment Preparation

This document describes how to ensure your environment is configured for working with Moodle on Azure.

Prerequisites

In order to configure our deployment and tools we'll set up some environment variables to ensure consistency.

Required software

We'll use a number of tools when working with Moodle on Azure. Let's ensure they are all installed:

sudo apt-get update
sudo apt-get install wget -y
sudo apt-get openssh-client -y

The Azure CLI is also important:

AZ_REPO=$(lsb_release -cs)
echo "deb [arch=amd64] https://packages.microsoft.com/repos/azure-cli/ $AZ_REPO main" | sudo tee /etc/apt/sources.list.d/azure-cli.list
sudo apt-key adv --keyserver packages.microsoft.com --recv-keys 52E16F86FEE04B979B07E28DB02C46DF417A0893
sudo apt-get install apt-transport-https
sudo apt-get update && sudo apt-get install azure-cli

Ensure we have a valid SSH key pair

We use SSH for secure communication with our hosts. The following line will check there is a valid SSH key available and, if not, create one.

if [ ! -f "$MOODLE_SSH_KEY_FILENAME" ]; then ssh-keygen -t rsa -N "" -f $MOODLE_SSH_KEY_FILENAME; fi

Checkout the Moodle ARM Template

The Moodle Azure Resource Manager template is hosted on GitHub. We'll checkout the template into our workspace.

git clone [email protected]:Azure/Moodle.git $MOODLE_AZURE_WORKSPACE/arm_template

Validation

After completing these steps we should have, amonst other things, a complete checkout of the Moodle templates from GitHub:

ls $MOODLE_AZURE_WORKSPACE/arm_template

Results:

azuredeploy.json  azuredeploy.parameters.json  CONTRIBUTE.md  docs  env.json  etc  images  LICENSE  LICENSE-DOCS  metadata.json  nested
README.md

We should also have a number of applications installed, such as the Azure CLI:

if hash az 2>/dev/null; then echo "Azure CLI Installed"; else echo "Missing dependency: Azure CLI"; fi
