What makes a project successful? For developers building cloud-native applications, successful projects thrive on transparent, consistent, and rigorous collaboration. That collaboration is one of the reasons that many open source projects, like Docker containers and Kubernetes, grow to become standards for how we build, deliver, and operate software. Our Open Source Guides and Introduction to innersourcing are great first steps to setting up and encouraging these best practices in your own projects.

However, a common challenge that application developers face is manually testing against inconsistent environments. Accurately testing Kubernetes applications can differ from one developer’s environment to another, and implementing a rigorous and consistent environment for end-to-end testing isn’t easy. It can also be very time consuming to spin up and down Kubernetes clusters. The inconsistencies between environments and the time required to spin up new Kubernetes clusters can negatively impact the speed and quality of cloud-native applications.

Building a transparent CI process

On GitHub, integration and testing becomes a little easier by combining GitHub Actions with open source tools. You can treat Actions as the native continuous integration and continuous delivery (CI/CD) tool for your project, and customize your Actions workflow to include automation and validation as next steps.

Since Actions can be triggered based on nearly any GitHub event, it’s also possible to build in accountability for updating tests and fixing bugs. For example, when a developer creates a pull request, Actions status checks can automatically block the merge if the test fails.
