Summary
In this chapter, we embarked on an enlightening journey, diving deep into the realms of centralized logging, automated alerting, and effective security orchestration for cloud-native applications.
We began with the exploration of the EFK stack – Elasticsearch, Fluentd, and Kibana – in the context of a Kubernetes environment. Elasticsearch serves as the search and analytics engine, Fluentd is for data collection and aggregation, and Kibana is for data visualization. We provided a detailed, step-by-step guide on setting up and securing an EFK stack on a Kubernetes cluster. We discussed the importance of PersistentVolumes to Elasticsearch data and the role of Helm, a package manager for Kubernetes, to ease the installation process. We also covered the critical aspects of securing the EFK stack for a production environment, and its maintenance and monitoring.
Following the EFK stack, we moved on to automated alerting systems, shedding light on the role of tools...
