- 1 Intro
- 2 What is Kubernetes(k8s)?
- 3 Declarative operation Define the elements/conditions in yaml/json The definition describes the final state, not the procedure Can check the change history by version control such as Git All you have …
- 4 What does k8s cluster consist of? The cluster consists of Control Plane and Nodes Control Plane Apiserver Controller manager
- 5 What is Control Plane doing? Make global decisions about the cluster, as well as detecting and responding to cluster events.
- 6 What is Node doing? Run the application deployed in the cluster Maintaining running pods and providing the Kubernetes runtime environment
- 7 Overview of K8s logging
- 8 The problem want to solve Difficult to investigate logs across components
- 9 Solution idea
- 10 Tracking the cause of operation Fujitsu
- 11 Check the impact of system failure
- 12 Overview of realization
- 13 Issues in implementation There are implementation issues in the following situations: Issue 1: Multiple requests are the cause of processing Issue 2: Multiple components operate in a chain with one r…
- 14 Multiple requests are the cause of processing When multiple requests are processed at the same time, it is necessary to associate multiple IDs with the processing.
- 15 The object to be processed is different from the object of the trigger Ex. Pod update processes replicaset with trigger
- 16 Current status Proposing KEP to enhance the logging function. We are thinking of an implementation and system design that can solve all the implementation issues.
