About Stern
Stern follows the logs of several Kubernetes pods, and of several containers inside each pod, in a single terminal stream. You pick what to follow with a regular expression or with a Kubernetes resource written as resource/name. Each result is colour coded so you can tell sources apart while debugging.
The project is a community-maintained fork of the discontinued wercker/stern. It suits developers and operators who find reading logs one pod at a time slow.
Strengths
- Follows many pods and containers in one stream
- Colour-coded output per source
- Selects pods by regular expression or resource name
Limitations
- Terminal only, with no graphical interface
- Needs access to a Kubernetes cluster
