Drone Github Comment

Drone is a Continuous Delivery system built on container technology. It uses a simple YAML configuration file, a superset of docker-compose, to define and execute Pipelines inside Docker containers.

Common use cases include:

1. Building Docker Images and pushing to container registry like Docker Hub/ECR
2. Checking & Fixing Lint/PSR4 Coding Standard errors.
3. Creating package builds and deploying to various cloud services.

At GradeUp, we use Drone to check for Lint errors for our projects and then build docker images. Lint step failures are common and thus we needed a way to simplify process of viewing CI errors. So we build a drone plugin in Golang to solve the issue.

When any step in CI process fails it throws error, users have to open Build logs and go to the step which failed to check the errors.

Drone Failed Pipeline

Drone Github Comment simplifies the process by going through the build logs and finding failed step, create a Github Comment on Pull Request with error logs. We can easily go the Pull Request Page and view the error directly on Github.
