Azure Manage Apps with AKS

Description

Proof of concept to show how to use a private container registry to distribute container images to an Azure Kubernetes Cluster using an Azure Virtual Machine.

Requirements

• Azure Ubuntu 18.04 VM
• Azure Account Subscription

Creation of VM Offer

• Create an Ubuntu VM and log in
• Download the setup script

wget https://raw.githubusercontent.com/code4clouds/amaaks/main/vmoffer-setup.sh
cat ./vmoffer-setup.sh | base64 -w 0 # to use for script for VM custom extension script (optional)
sudo chmod +x ./vmoffer-setup.sh
 ./vmofffer-setup.sh

• Create a Harbor repository entry
• Seed Harbor using the replication feature by using your repository entry
• Make sure the replica reposity is maked as public in Harbor
• Generalize
• Create an image for internal deployments or VM Offer (if targeting the Azure Marketplace) by generalizing the VM

sudo waagent -deprovision+user --force
sudo waagent -force -deprovision+user && export HISTSIZE=0 && sync
logout

• Deallocate the VM

 az vm deallocate --resource-group amaaks --name amaaks
 az vm generalize --resource-group amaaks --name amaaks
 az image create --resource-group amaaks --name amaaks --source amaaks

• Create Snapshot
• Add the image to the image gallery
• Add the image gallery to the IAM of the resource group.
• Reference the new image in the mainTemplate.json. The sample below is for a publicly hidden VM Offer Live in the Azure Marketplace.

        {
            "name": "[parameters('virtualMachineName')]",
            "type": "Microsoft.Compute/virtualMachines",
            "apiVersion": "2020-06-01",
            "location": "[parameters('location')]",
            "plan": {
                "name": "<planId>",
                "publisher": "<publisherid>",
                "product": "amaaks"
            },
            "dependsOn": [
                "[concat('Microsoft.Network/networkInterfaces/', parameters('networkInterfaceName'))]"
            ],
            "properties": {
                "hardwareProfile": {
                    "vmSize": "[parameters('virtualMachineSize')]"
                },
                "storageProfile": {
                    "imageReference": {
                        "publisher": "<publisherId>",
                        "offer": "amaaks",
                        "sku": "<planId>",
                        "version": "latest"
                    },
                    "osDisk": {
                        "createOption": "fromImage",
                        "managedDisk": {
                            "storageAccountType": "[parameters('osDiskType')]"
                        }
                    }
                },

• Deploy the teamplate

./template-deploy.sh

• Or Deploy as a manage app

./ama-deploy/sh <your email>

Plain Ubuntu Image VM

 base64 -w 0 vmoffer-fullscript.sh > vmoffer-fullscript.sh.b64

Add the out put to the template under "vm-script"

Testing

Clicking on the button below, will create the Managed Application definition to a Resource Group in your Azure subscription.

./ama-deploy.sh <your_azure_email>

The output will container the K8s kubeconf copy it to a file (e.g. kubeconfig.b64) then decode it and move it to your home directory.

 cat kubeconfig.b64 | base64 --decode > ~/.kube/config
