I am using eks and version 1.14 and helm charts are based of 1.14. Have been seen these warnings when performing pulumi up. Am I doing something wrong?

Those warnings are just giving you a heads up that those apiVersions will stop working once the cluster version hits 1.16 so that you have time to fix your deployments before then. If you don’t want to see those warnings, you can disable them with https://www.pulumi.com/docs/reference/pkg/nodejs/pulumi/kubernetes/#ProviderArgs-suppressDeprecationWarnings

Thanks @gorgeous-egg-16927 for pointing out the flag and your explanation. This answers my question.
