Configuring a logging, monitoring, and alerting stack using the EFK toolset

In cases where we need to analyze massive volumes of log data collected by Pods running many services and applications on a Kubernetes cluster, a centralized, cluster-level logging stack could be useful. EFK is the most popular centralized logging solution. Elasticsearch is a real-time search engine that supports full-text and structured searches, as well as analytics, and is distributed and scalable. It's most commonly used for indexing and searching large amounts of log data. Elasticsearch is widely used in conjunction with Kibana, a powerful data visualization frontend and dashboard for Elasticsearch. Kibana is a web-based tool that allows you to quickly query and get insight into Kubernetes applications by viewing Elasticsearch log data and creating dashboards and queries. To gather, transform, and transfer log data to the Elasticsearch backend, we'll use Fluentd, a popular open source data collector...
