is it possible to check with pulumi when a pod is ready? I have a deployments that depends on another pod's endpoint to be ready before it starts. We use Typescript to configure our pulumi deployments.

Assuming that Pod is not managed by Pulumi, this is related to https://github.com/pulumi/pulumi-kubernetes/issues/1656 Probably your best bet for now would be using a k8s client in TS, or shelling out to kubectl. https://www.pulumi.com/blog/dynamic-providers/ is relevant reading for that.
