Significant increase in memory usage from v4.18.0 onwards #3713
Description
Describe what happened
pulumi-kubernetes consumes far more memory after the v4.18.0 release.
Sample program
I'm running a kind cluster for testing:
import * as kubernetes from "@pulumi/kubernetes";
const provider = new kubernetes.Provider("kubernetes-provider", {
context: "kind-kind",
enableServerSideApply: true,
});
for (let i = 0; i < 100; i++) {
new kubernetes.batch.v1.Job(
`test-job-${i}`,
{
spec: {
template: {
spec: {
containers: [
{
name: "hello-world",
image: "busybox",
command: ["/bin/sh", "-c", `sleep 10`],
},
],
restartPolicy: "OnFailure",
},
},
backoffLimit: 4,
},
},
{ provider },
);
}Log output
