Currently, to update Kubernetes resources, we use kubectl version 1.20, hardcoded in a lambda layer. For now, this works fine, but eventually, as new Kubernetes versions are released, they won't be compatible with the client anymore. Also, it's not an option to always use the latest version of the client, as we know that kubectl version 1.21.0 is not compatible with version 1.20 (and lower) of the server.
