Change log since v1.2.0

New CRD and Controller: PodProbeMarker

Kubernetes provides three Pod lifecycle management:

• Readiness Probe Used to determine whether the business container is ready to respond to user requests. If the probe fails, the Pod will be removed from Service Endpoints.
• Liveness Probe Used to determine the health status of the container. If the probe fails, the kubelet will restart the container.
• Startup Probe Used to know when a container application has started. If such a probe is configured, it disables liveness and readiness checks until it succeeds.

So the Probe capabilities provided in Kubernetes have defined specific semantics and related behaviors. In addition, there is actually a need to customize Probe semantics and related behaviors, such as:

• GameServer defines Idle Probe to determine whether the Pod currently has a game match, if not, from the perspective of cost optimization, the Pod can be scaled down.
• K8S Operator defines the main-secondary probe to determine the role of the current Pod (main or secondary). When upgrading, the secondary can be upgraded first, so as to achieve the behavior of selecting the main only once during the upgrade process, reducing the service interruption time during the upgrade process.

So we provides the ability to customize the Probe and return the result to the Pod yaml.

For more detail, please refer to its documentation and proposal.
