When you connect to a Git repository from your Git client for the first time, the credential manager prompts for credentials. Provide your Microsoft account or Azure AD credentials.

Note: Git Credential Managers simplify authentication with your Azure Repos Git repositories. Credential managers let you use the same credentials that you use for the Azure DevOps Services web portal. Credential managers support multi-factor authentication through Microsoft account or Azure Active Directory (Azure AD). Besides supporting multi-factor authentication with Azure Repos, credential managers also support two-factor authentication with GitHub repositories.

WhiteSource is the leader in continuous open source software security and compliance management. WhiteSource integrates into your build process, irrespective of your programming languages, build tools, or development environments. It works automatically, continuously, and silently in the background, checking the security, licensing, and quality of your open source components against WhiteSource constantly-updated definitive database of open source repositories.

Azure DevOps integration with WhiteSource Bolt will enable you to:

Detect and remedy vulnerable open source components.

Generate comprehensive open source inventory reports per project or build.

Enforce open source license compliance, including dependencies’ licenses.

Identify outdated open source libraries with recommendations to update.

Instead implement Continuous Assurance for the project.

To configure your Azure Functionaz400-38443478-functto automatically update whenever new code is committed to the main branch of the specified GitHub repository, you can use GitHub Actions for continuous deployment. Here’s how to set it up:

Create a GitHub Actions Workflow:

In your GitHub repository, navigate to the.github/workflows/directory.

Create a new file for your workflow (e.g.,azure-function-cd.yml).

Define the Workflow:

In the workflow file, define the steps for the build and deployment process.

Use theAzure/functions-actionto deploy to your Azure Function App.

Set up triggers for themainbranch to initiate the workflow on every commit.

Generate Deployment Credentials:

In the Azure Portal, navigate to your Function Appaz400-38443478-funct.

Download the publish profile from theOverviewsection by clicking onGet publish profile.

Store the Publish Profile as a GitHub Secret:

In your GitHub repository, go toSettings > Secrets and variables > Actions.

Create a new secret (e.g.,AZURE_FUNCTIONAPP_PUBLISH_PROFILE) and paste the content of the publish profile.

Configure the Workflow to Use the Secret:

In the workflow file, reference the secret to authenticate the deployment to Azure.

Here’s a sample GitHub Actions workflow snippet:

name: Deploy Azure Function

on:

push:

branches:

- main

jobs:

build-and-deploy:

runs-on: ubuntu-latest

steps:

- uses: actions/checkout@v2

- name: Set up Python version

uses: actions/setup-python@v2

with:

python-version: ' 3.x '

- name: Install dependencies

run: |

pip install -r requirements.txt

- name: Deploy to Azure Functions

uses: Azure/functions-action@v1

with:

app-name: az400-38443478-funct

publish-profile: ${{ secrets.AZURE_FUNCTIONAPP_PUBLISH_PROFILE }}

package: .

Replace theapp-namewith the name of your Azure Function App and ensure the Python version and dependencies match your application’s requirements.

By following these steps, yourAzure Function will automatically update whenever new code is pushed to the main branch of the GitHub repository. This setup minimizes manual effort and ensures that your function app is always running the latest code.

To ensure that your Azure Web App namedaz400-38443478-mainsupports rolling upgrades and only 10 percent of users connect to the updated version of the app, you can use deployment slots with the followingsteps:

Create a Deployment Slot:

Navigate to the Azure Portal.

Go to your Web Appaz400-38443478-main.

SelectDeployment slotsin the menu.

Click onAdd Slot.

Name the slot (e.g.,staging) and if needed, clone settings from the production slot.

Configure the Traffic Percentage:

In the Deployment Slots menu, you will see a column forTraffic %.

Set the traffic percentage to10%for thestagingslot1.

This will route only 10% of the traffic to the updated version of the app in thestagingslot.

Deploy the Updated App to the Staging Slot:

Deploy yourupdated application to thestagingslot.

Test the application in thestagingslot to ensure it’s working as expected.

Complete the Rolling Upgrade:

Once you’re satisfied with the performance and stability of the app in thestagingslot, you can graduallyincrease the percentage of traffic until you’re ready to swap with the production slot.

To swap slots, go to theDeployment slotsmenu and click onSwapwith the production slot.

By using deployment slots, you can achieve rolling upgrades with minimal administrative effort, as it allows you to test the new version on a subset of users before fully releasing it. Remember to adjust the traffic percentage and monitor the application’s performance throughout the process.

Step 1: Kubectl create

You can add a service account to Tiller using the --service-account < NAME > flag while you’re configuring Helm (step 2 below). As a prerequisite, you’ll have to create a role binding which specifies a role and a service account name that have been set up in advance.

Example: Service account with cluster-admin role

$ kubectl create -f rbac-config.yaml

serviceaccount " tiller " created

clusterrolebinding " tiller " created

$ helm init --service-account tiller

Step 2: helm init

To deploy a basic Tiller into an AKS cluster, use the helm init command.

Step 3: helm install

To install charts with Helm, use the helm install command and specify the name of the chart to install.
