Azure DevOps Pipeline

This guide will walk you through the process of setting up an Azure DevOps Pipeline to build, push, and deploy app changes to your Azure container repository.

note

Before getting started, you'll need:

• A Massdriver account
• A Massdriver service account
• An Azure DevOps repository with your application code
• The Mass CLI extension for Azure DevOps

Applications

Publish your application

Before you can set up an Azure DevOps Pipeline to deploy your application, first you'll need to publish it to Massdriver and create a package. You can do this by following the Create App guide.

After you publish your application, you'll need to create a package. You can do this by dragging your application out from the bundle bar in the Massdriver canvas. Fill in the fields of your application and click Save.

Set secrets and vars

Once you've published your application, you'll need to set the following variables in your Azure DevOps Pipeline:

Name	Description	Type	Notes
MASSDRIVER_ORG_ID	Your Massdriver organization ID	secret	Copy your Organization ID
MASSDRIVER_API_KEY	Your Massdriver API key	secret	Create a Service Account
MASSDRIVER_ARTIFACT_ID	The ID of the authentication artifact in Massdriver	secret	Copy your Artifact ID
NAMESPACE	The namespace of your build	variable	If it does not exist paired with the IMAGE_NAME, then it will be created for you
IMAGE_NAME	The image name of your build	variable	If it does not exist paired with the NAMESPACE, then it will be created for you
REGION	The region where your cloud container repository is located	variable	Must be a valid cloud region. For example: eastus for Azure, or us-west-1 for AWS.

Workflow file

To set up the pipeline, create a new pipeline and select where your code is, then select your repository. When selecting a template, select Starter Pipeline. You can then use this example below as a starting point:

azure-pipelines.yml

trigger:
  branches:
    include:
    - main

pool:
  vmImage: 'ubuntu-latest'

variables:
  MASSDRIVER_ORG_ID: $(MASSDRIVER_ORG_ID)
  MASSDRIVER_API_KEY: $(MASSDRIVER_API_KEY)

stages:
- stage: DeployToMassdriver
  jobs:
  - job: push_and_deploy
    steps:
    - checkout: self

    - task: mass-cli-install@0
      displayName: 'Install Massdriver CLI'

    - task: mass-image-push@0
      displayName: 'Push Image'
      inputs:
        namespace: $(NAMESPACE)
        imageName: $(IMAGE_NAME)
        artifact: $(MASSDRIVER_ARTIFACT_ID)
        region: $(REGION)
        imageTag: $(Build.SourceVersion) # Sets image tag to git commit sha
        buildContext: './' # Path to Dockerfile

    - task: mass-bundle-publish@0
      displayName: 'Publish Bundle'
      inputs:
        buildDirectory: './massdriver' # Path to massdriver.yaml file

    - task: mass-app-patch@0
      displayName: 'Set Image Version'
      inputs:
        project: <insert-project-name-here>
        env: <insert-environment-name-here>
        manifest: <insert-manifest-name-here>
        set: '.image.tag="$(Build.SourceVersion)"'

    - task: mass-app-deploy@0
      displayName: 'Deploy App'
      inputs:
        project: <insert-project-name-here>
        env: <insert-environment-name-here>
        manifest: <insert-manifest-name-here>

This example is configured to trigger on pushes to the repository's main branch. Be sure to update the trigger to match your branching and git workflow process.

When this DevOps Pipeline runs, it will:

• Build and push your image to your Azure container repository
• Update the tag in your application package
• Redeploy your application in Massdriver with the updated tag

Infrastructure

Publish your bundle

Before you can set up an Azure DevOps Pipeline to automate publishing your bundle, first you'll need to manually publish it to Massdriver and create a package. You can do this by following the Bundle Creation Walkthrough guide.

After you publish your bundle, you'll need to create a package. You can do this by dragging your bundle out from the bundle bar in the Massdriver canvas. Fill in the fields of your bundle and click Save.

Set secrets

Name	Description	Type	Notes
MASSDRIVER_ORG_ID	Your Massdriver organization ID	secret	Copy your Organization ID
MASSDRIVER_API_KEY	Your Massdriver API key	secret	Create a Service Account

FAQs

Where can I find my secrets, project, environment, and manifest names?

• Secrets & vars
• Project, environment, and manifest names are found in the Massdriver package name:

Where can I find my image tag path?

The image tag path is the jq formatted path to the image tag field in the params section of your application's massdriver.yaml file. For example, if your massdriver.yaml file looks like this:

massdriver.yaml

runtime:
  type: object
  title: Runtime Settings
  required:
    - image
  properties:
    image:
      type: object
      title: Container Image
      required:
        - tag
      properties:
        tag:
          title: ACR image tag
          description: Specific version of the container to pull.
          type: string
          default: latest

Then your image tag path would be .runtime.image.tag.

I have subdirectories in my repository. How do I set the build context?

• If your Dockerfile is in a subdirectory, you can update the buildContext to point to that directory. For example, if your Dockerfile is in the ./app directory, you can set the buildContext to ./app.
• If your massdriver.yaml file is in a subdirectory, you can update the buildDirectory to point to that directory. For example, if your massdriver.yaml file is in the ./app/massdriver directory, you can set the buildDirectory to ./app/massdriver.
