Today, we are going to talk about the EFK stack: Elasticsearch, Fluent, and Kibana. You will learn about the stack and how to configure it to centralize logging for applications deployed on Kubernetes. We will focus on Fluentbit, as it is the lightweight version of Fluentd and more suitable for Kubernetes. Additionally, we will talk about how we reached the final solution and the hurdles we had to overcome. Last but not least, we’ll show you how we handled application logs without actually installing 3rd party clients.
In the DevOps era, where very much emphasis is placed on automation, having reliable, predictable and fast pipelines is a must. Fortunately, there are many options for you to try, like Jenkins, Buildbot, Drone, Concourse and so on. If you are trying to run jobs on Kubernetes there is also the new Jenkins X available. This brings major changes to Jenkins, like running jobs in the cluster. Yet, if you host your code on GitLab, you should use their CI/CD tool because it can save you a lot of time and money when done right. In this article, we will showcase the main steps behind running GitLab-Runners on Kubernetes.
