Apigee Edge integration with GitLab

Hi all, we want to create a project where we can integrate Apigee edge with CI/CD pipeline in GitLab. We developed the proxy using maven(pom.xml) and now it needs to be integrated in GitLab CI/CD pipeline for automation. Please suggest how to achieve this whole problem and what steps need to be followed. Also, if any relevant documentation is there please feel free to share it.
