Add GlobalManager high availability support #66

Open llhuii opened 3 years ago

llhuii commented 3 years ago

What would you like to be added/modified: Add GlobalManager multi-instance support for high availability and high throughput.

Why is this needed: Currently GlobalManager is deployed as a k8s deployment with replicas=1, and only one instance is supported.

For GlobalManager's high availability and high throughput, we need to deploy GlobalManager with replicas >=2.

Proposal

Leverage the client-go leader-election feature, see the example.

Also see these --leader- options in kube-controller-manager.

--leader-elect:   Start a leader election client and gain leadership before executing the main loop. Enable this when running replicated components for high availability.
