How to Implement CICD using Azure DevOps | CICD process flow diagram using Azure DevOps | How to migrate applications into Azure Cloud using Azure DevOps Pipelines

 

Azure DevOps is a set of development tools and services offered by Microsoft to facilitate the entire software development lifecycle (SDLC). Azure DevOps is designed to support collaboration among development and operations teams, automate various aspects of the software development process, and enable continuous integration and continuous delivery (CI/CD) pipelines.

What is Continuous Integration?

Continuous integration is a DevOps software development practice where developers regularly merge their code changes into a central repository, after which automated builds and tests are run.

The key goals of continuous integration are to find and address bugs quicker, improve software quality, and reduce the time it takes to validate and release new software updates.

Azure DevOps is widely used for implementing CICD. Azure DevOps can integrate with other tools using Add-ons.

How does Continuous Integration Work?

Developers frequently commit to a shared repository using a version control system such as Git. Prior to each commit, developers may choose to run local unit tests on their code as an extra verification layer before integrating. A continuous integration service automatically builds and runs unit tests on the new code changes to immediately surface any errors.

Benefits of Continuous Integration

• Improve Developers productivity 
• Find bugs early in the software development stage
• Deliver products into market place sooner
• Improve the feedback loop

What is Continuous Delivery?

Continuous delivery is a software development practice where code changes are automatically prepared for a release to production. Continuous delivery is the next extension of continuous integration. The delivery phase is responsible for packaging an artifact together to be delivered to end-users. This phase runs automated building tools to generate this artifact.

Benefits of Continuous Delivery

• Automate the Software Release Process
• Improve Developer Productivity
• Find bugs early in the software development stage
• Deliver updates faster

How to Set Up AquaSec Trivy Scanner | How to install AquaSec Trivy Scanner on Linux OS

What is Trivy?

• open-source security scanner tool developed by Aqua Security. 
• Used for vulnerability scanning in such as 
• container images 
• file systems/folders 
• Git repositories
• Kubernetes clusters
• misconfiguration in files such as Terraform, K8S manifest files
• Trivy helps identify security issues and misconfigurations early in the software development lifecycle.

How to Install Trivy scanner?

Trivy scanner can be installed so many ways. Check here for more information. But we will using APT package manager to install on Ubuntu.

sudo apt-get install wget gnupg -y

wget -qO - https://aquasecurity.github.io/trivy-repo/deb/public.key | gpg --dearmor | sudo tee /usr/share/keyrings/trivy.gpg > /dev/null 

echo "deb [signed-by=/usr/share/keyrings/trivy.gpg] https://aquasecurity.github.io/trivy-repo/deb generic main" | sudo tee -a /etc/apt/sources.list.d/trivy.list 

sudo apt-get update 

sudo apt-get install trivy -y

Check Trivy got installed

trivy --version

This confirm that Trivy got installed successfully.
