Azure VM Scale Sets: Source to Prod

Deploy a DevOps VM with a sample source-to-prod pipeline targeting Virtual Machine Scale Set on Azure.

In this codelab, you will create a source-to-prod continuous delivery pipeline for a simple java based application targeting VM Scale Sets in Azure.

After completing this lab the following workflow will happen:

  1. A developer pushes a commit to Github
  2. Jenkins automatically builds a Debian package and pushes it to an Aptly repository
  3. Spinnaker bakes the new package into an image
  4. Spinnaker deploys to a test environment and disables the previous deployment
  5. Spinnaker waits for a manual judgement of the test environment
  6. Spinnaker deploys the image to the production environment and disables the previous deployment.

This codelab will walk through the following steps to implement this scenario:

1. Deploy Spinnaker and Jenkins on Azure

You need the following resources to perform the codelab:

  • Azure subscription: You can create one for free using the Azure Free trial .
  • Spinnaker and Jenkins VM:

From a shell run the following command that will walk you through all the steps necessary to deploy Jenkins and Spinnaker in Azure.

NOTE: When running the following script, ensure that you type vmss when asked to select the target.

  1. bash <(curl -sL https://aka.ms/DeployDevOps)

In the output of the above script you will find the command to open an SSH tunnel to the DevOps VM that has just been deployed. The command should look like this:

  1. ssh -L 8080:localhost:8080 -L 9000:localhost:9000 -L 8084:localhost:8084 -L 8087:localhost:8087 username@fqdn_of_your_devops_vm

NOTE: You will have to enter the password that you have specified in the previous step.

2. Verify Jenkins

  1. After you have started your ssh tunnel, navigate to http://localhost:8080/ on your local machine.

  2. The instance should already be unlocked and your first account setup. Login with the credentials you specified when deploying the template.

  3. Click Install suggested plugins: Install Jenkins plugins

  4. Your Jenkins instance is now ready to use!

  5. Run the Sample Aptly Job by clicking on the run button for the job. Verify that the job completes successfully.

    Run Jenkins job

3. Prepare your environments

I. Create the “codelab” application

  1. Navigate to your Spinnaker dashboard by using http://localhost:9000 on your local machine.

  2. Click on the Actions menu on the right

    Actions

  3. In the New Application window, enter the following values:

  • Name: codelab

  • Owner Email: Enter your email

    And click Create

    New Application

    You can read more how the Spinnaker application matches to Azure resources in the Azure reference for Spinnaker

II. Create a firewall

  1. Navigate to the FIREWALLS page and click on the Create Firewall button.
  2. Provide the following values in the Create New Firewall dialog:
  • Detail: web

  • Account: my-azure-account (should be selected by default)

  • Region: westus (select the region that is closest to your location)

    Ingress (click Add new Firewall Rule):

  • Protocol: TCP

  • Start Port: 80

  • End Port: 80

    And click Create, if the loadbalancer does not appear in the page once the creation is complete, refresh your browser.

    New Firewall

Note: We are using westus for the region but you can select any other region that is closer to your location. Be careful to match the region in the following steps.

You can read more about the implementation of Network Security Groups in Azure in the Azure reference for Spinnaker

III. Create a load balancer

  1. Navigate to the LOAD BALANCERS page and click the Create Load Balancer button.
  2. Provide the following values in the “Create New Load Balancer” dialog:
  • Account: my-azure-account

  • Region: westus (unless you have selected a different region previously)

  • Virtual Network: devopsVnet

  • Subnet: devopsSubnet1

  • Stack: test

  • Detail: frontend

    Verify that the Listener is configured as follows:

  • Protocol: HTTP

  • External Port: 80

  • Internal Port: 8080

    And click Create.

    Create test load balancer

    The virtual network devopsVnet and the subnets devopsSubnet# were created for you by the script that you ran in the Deploy Spinnaker and Jenkins on Azure step.

    You can learn more about the implementation of the Spinnaler Load Balancer in the Azure reference for Spinnaker .

  1. Repeat the above steps to create a second load balancer for production. Use the same parameters but the following change:
  • Stack: prod

    Create prod load balancer

NOTE: It will take approximately 15 minutes to provision the two loadbalancers.

4. Create the continuous delivery pipeline

In this section you will create a Spinnaker pipeline that will bake the image from a Jenkins build then deploy it to test.

I. Create a new pipeline

  1. Navigate to the PIPELINES page and click on the New button (+ sign) on the right to create a new pipeline.

  2. Name your pipeline: “Deploy codelab” and click Create.
