Continuous Integration (CI) is the practice of building and testing the application on each update. By working in small increments, errors are detected earlier and promptly resolved.

Once integration is complete and all tests have passed, we can add Continuous Delivery (CD) to automate the release and deployment process. A project that uses CI/CD can make more frequent and reliable releases.

We’ll use Semaphore, a fast, powerful and easy-to-use Continuous Integration and Delivery (CI/CD) platform to automate the whole process:

Install project dependencies.

Run unit tests.

Build a Docker image.

Push the image to Docker Hub.

Provide a one-click Kubernetes deployment.
