Leveraging the potential of automation and collaboration for rapid and consistent application delivery can be achieved by implementing continuous integration/continuous delivery (CI/CD) pipelines in DevOps. The efficiency of these pipelines can be further increased by integrating them with external tools like dependency scanning, security scanning, and code coverage. This article aims to provide an understanding of how one can achieve this integration, particularly in the context of preparing for the Microsoft AZ-400 exam: “Designing and Implementing Microsoft DevOps Solutions”.
Dependency Scanning
Dependency scanning is an important aspect of DevOps that helps identify known vulnerabilities within an application’s dependencies or libraries. When integrated with your CI/CD pipelines, it helps catch potential security threats early on. For instance, WhiteSource Bolt is a tool one can use with Azure DevOps to continuously scan your libraries and dependencies for vulnerabilities.
steps:
– task: whitesource.ws-bolt.Bolt.bolt-task.whitesourceBolt@19
inputs:
cwd: ‘$(System.DefaultWorkingDirectory)’
The above YAML code is an example of how you could integrate WhiteSource Bolt into your pipeline using a simple task.
Security Scanning
Security scanning in CI/CD is a proactive measure to uncover vulnerabilities in the codebase. It allows developers to fix issues before they become a risk. In Azure DevOps, Microsoft has provided built-in tasks for popular security scanning tools such as SonarQube or Fortify. With these tasks, you can automatically run scans whenever the pipeline runs.
steps:
– task: SonarQubePrepare@4
inputs:
SonarQube: ‘sonarCloud’
scannerMode: ‘MSBuild’
projectKey: ‘projectKey’
projectName: ‘projectName’
The YAML script above demonstrates how SonarQube can be plugged into the pipeline to assess code quality and detect vulnerabilities.
Code Coverage
Code coverage helps ensure that the written tests are effective and that they actually cover the code. It is a crucial part of software testing that determines the extent to which the source code of a program has been tested. Azure Pipelines supports multiple testing frameworks and provides built-in tasks for generating and publishing code coverage results. Let’s take an example of how we can use DotCover to generate a code coverage report.
steps:
– task: DotNetCoreCLI@2
inputs:
command: ‘test’
projects: ‘/*Tests/*.csproj’
arguments: ‘–configuration $(buildConfiguration) /p:CollectCoverage=true /p:CoverletOutputFormat=cobertura’
– task: PublishCodeCoverageResults@1
inputs:
codeCoverageTool: ‘cobertura’
summaryFileLocation: ‘$(System.DefaultWorkingDirectory)//coverage.cobertura.xml’
This example shows a simple way to generate a code coverage report using DotCover with the ‘test’ command and then publish the results using the `PublishCodeCoverageResults` task.
By integrating CI/CD pipelines with external tools like dependency scanning, security scanning, and code coverage, teams can garner an array of benefits. Some of these include improving code quality, automating processes, identifying vulnerabilities in advance and providing a comprehensive understanding of the source code structure.
To excel at AZ-400: Designing and Implementing Microsoft DevOps Solutions exam, understanding the concept and implementation of these tools in Azure DevOps is crucial. Continue to explore the Microsoft documentation for more details and examples.
