NOTE! This project has now been integrated with the Onix project and is part of its Kubernetes Bundle. Please go here for the new Sentinel project.
An explanation of how Sentinel fits in Onix can be found here
Sentinel is a Go application, which looks for state changes of kubernetes objects, and publish their associated metadata to specific endpoints for further processing by downstream systems.
The application process can either run inside or outside of a Kubernetes cluster and can publish events to either a webhook or to an instance of the Apache Kafka message broker.
The following image shows how the application works:
| Name | Description |
|---|---|
| Getting Started | Various examples of how to get started using Sentinel. |
| Configuration | How to change Sentinel behaviour using configuration variables. |
| Publishers | A description of the various mechanisms to publish status changes to other systems. |
| Scripts | Various scripts to facilitate development and testing. |
The current version uses the Kubernetes API 1.11.10, compatible with Openshift 3.11.
To build the solution for another api version, the dependencies in the go module file has to be updated, for example, using go get as follows:
# for example, to update to version 1.14.2
$ go get -u k8s.io/[email protected]
$ go get -u k8s.io/[email protected]
$ go get -u k8s.io/[email protected]NOTE: the minimal required go version is 1.12.5
