Several years ago I discovered how useful Docker might be for CI/CD using Jenkins. Now, time arrived to share that with you. You may say that it’s old news because there are a lot of new tools and technologies enabling CI/CD other than Jenkins. Nevertheless, many companies still do CI/CD using Jenkins. Additionally, they might use Docker for packaging the applications. Do their Jenkins instances run in Docker as well? Preferably, they do. If you feel it’s too much, don’t worry 🙂 I’ll showcase CI/CD of web app using Docker and Jenkins. Keep reading to find out more details 🙂
Have you ever been frustrated by the fact thatPrometheus exporters don’t export the metrics you want? I was. So I wondered how easy it is to create a custom Prometheus exporter in Python. In fact, it’s very easy to build a new Prometheus exporter using Prometheus python client.
Therefore, we’ll develop custom Prometheus exporter in Python and show how to debug it fast. For this purpose, we’ll raise a fully functional Jenkins monitoring stack using docker.
