CI/CD with Docker @ benhall/golang-demo

What is CI/CD with Docker?

Continuous Integration and Continuous Delivery (CI/CD) is a software development practice that automates the building, testing, and deployment of applications. This practice helps to ensure that code changes are integrated and delivered to users quickly and reliably.

Docker is a containerization platform that allows developers to package their applications and dependencies into portable containers. These containers can be run consistently across different environments, such as development, testing, and production.

CI/CD with Docker combines these two technologies to streamline the software development lifecycle. By using Docker to build and package applications, CI/CD pipelines can be created that automate the following steps:

  • Building the application: Docker images are built from the source code and all dependencies.
  • Testing the application: The application is tested within a Docker container to ensure that it works as expected.
  • Deploying the application: The Docker image is deployed to a container orchestration platform, such as Kubernetes, for production.

By using Docker in CI/CD pipelines, developers can achieve the following benefits:

  • Faster deployment times: Docker images are lightweight and portable, which can significantly reduce deployment times.
  • Improved consistency: Docker containers ensure that applications run consistently across different environments.
  • Increased reliability: By automating the deployment process, CI/CD pipelines help to reduce the risk of human error.
  • Reduced costs: Docker containers can help to reduce the costs associated with infrastructure and software licensing.

Why is CI/CD with Docker important?

CI/CD with Docker is essential for modern software development because it enables:

  • Faster time to market: By automating the deployment process, CI/CD pipelines can significantly reduce the time it takes to deliver new features and bug fixes to users.
  • Improved quality: Automated testing within CI/CD pipelines helps to catch bugs early in the development process, which can improve the overall quality of the software.
  • Increased agility: CI/CD pipelines allow development teams to be more agile and responsive to changing requirements.
  • Enhanced collaboration: CI/CD pipelines facilitate collaboration between developers, testers, and operations teams.
