Every request made against a storage service must be authorized, unless the request is for a blob or container resource that has been made available for public or signed access. One option for authorizing a request is by using Shared Key.

Scenario: The mobile applications must be able to call the share pricing service of the existing retirement fund management system. Until the system is upgraded, the service will only support basic authentication over HTTPS.

The investment planning applications suite will include one multi-tier web application and two iOS mobile application. One mobile application will be used by employees; the other will be used by customers.

Box 1: A source control system

A source control system, also called a version control system, allows developers to collaborate on code and track changes. Source control is an essential tool for multi-developer projects.

Box 2: A hosted service

To build and deploy Xcode apps or Xamarin.iOS projects, you'll need at least one macOS agent. If your pipelines are in Azure Pipelines and a Microsoft-hosted agent meets your needs, you can skip setting up a self-hosted macOS agent.

Batching CI runs

If you have many team members uploading changes often, you may want to reduce the number of runs you start. If you set batch to true, when a pipeline is running, the system waits until the run is completed, then starts another run with all changes that have not yet been built.

Example:

# specific branch build with batching

trigger:

batch: true

branches:

include:

- master

To clarify this example, let us say that a push A to master caused the above pipeline to run. While that pipeline is running, additional pushes B and C occur into the repository. These updates do not start new independent runs immediately. But after the first run is completed, all pushes until that point of time are batched together and a new run is started.

Box 1: rwx

The Log Analytics agent for Linux runs as the omsagent user. To grant >write permission to the omsagent user, run the command setfacl -m u:omsagent:rwx /tmp.

Box 2: /tmp

Deploying DSC to a Linux node uses the /tmp folder.

Step 1: Initialize the Default Main Branch

Navigate to Azure DevOps:

Go to Azure DevOps and sign in with your credentials.

Select Your Project:

Choose Project1 from your list of projects.

Initialize the Main Branch:

Go to Repos > Files.

If the main branch does not exist, you will see an option to initialize it. Click on Initialize and follow the prompts to create the main branch.

Step 2: Implement an Approval Process for the Main Branch

Navigate to Branch Policies:

Go to Repos > Branches.

Find the main branch and click on the … (ellipsis) next to it.

Select Branch policies.

Enable Required Reviewers:

Under Policies, enable Minimum number of reviewers.

Set the minimum number of reviewers to 2 to enforce the four-eyes principle.

Add Required Reviewers:

Add the users who should review the changes. Ensure that at least one approval is required on every iteration.

Enable Reset Code Reviewer Votes:

Enable the Reset code reviewer votes when there are new changes option to ensure that any new changes require re-approval.

Save Changes:

Click on Save changes to apply the policies.

Step 3: Verify the Approval Process

Create a Pull Request:

Make a change in a branch and create a pull request to merge it into the main branch.

Review and Approve:

Ensure that the pull request requires at least two reviewers to approve it before it can be merged.

By following these steps, you will have successfully initialized the main branch and implemented an approval process that adheres to the four-eyes principle, ensuring that every iteration has at least one approval
