tailing sidecar is a streaming sidecar container, the cluster-level logging agent for Kubernetes.
It helps when your application inside the Pod cannot write to standard output and/or standard error stream or when it outputs additional logs to a file instead (eg. the gc.log).
It tails the files inside Kubernetes Pods, handling situations like the file not being there when tailing starts, tailing multiple files, rotating files, etc.
It uses Fluent Bit under the hood, benefiting from its performance.
For more information about cluster-level logging architecture please read Kubernetes documentation.
The project consists of two parts:
- tailing sidecar container image which can be used to manually extend Pods by tailing sidecars
- tailing sidecar operator which automatically adds tailing sidecars to Pods based on configuration provided in annotation
