The pre-install/pre-upgrade hook applies the node pools and the drain
KafkaRebalance with kubectl, and its container has no resources of its
own, so in a tenant with resource quotas it runs under the LimitRange
default of 128Mi. When it applies an object that already exists,
kubectl downloads the cluster's whole OpenAPI v2 document only to
decide that a custom resource takes a JSON merge patch: with the 374
CRDs of an e2e cluster that peaks at about 300Mi, so every upgrade of a
Kafka in such a tenant OOM-kills the hook and fails with "pre-upgrade
hooks failed".
--openapi-patch=false skips that lookup and builds the same three-way
merge patch from the last-applied annotation, peaking at about 35Mi on
the same cluster. A server-side apply would be as small but changes
what gets removed: the "kafka" pool is created with "kubectl create",
whose manager keeps co-owning every field it set, so a later
server-side apply leaves those fields in place when the chart drops
them. A larger memory limit would charge every upgrade against the
tenant quota instead.

Cozystack
Cozystack is a free and open-source platform and framework for building clouds.
Cozystack is a CNCF Sandbox project that was originally built and sponsored by Ænix.
With Cozystack, you can transform a bunch of servers into an intelligent system with a simple REST API for spawning Kubernetes clusters, Database-as-a-Service, virtual machines, load balancers, HTTP caching services, and other services with ease.
Use Cozystack to build your own cloud or provide a cost-effective development environment.
Use-Cases
-
Using Cozystack to build a public cloud
You can use Cozystack as a backend for a public cloud -
Using Cozystack to build a private cloud
You can use Cozystack as a platform to build a private cloud powered by Infrastructure-as-Code approach -
Using Cozystack to build your own platform
You can install only the Cozystack components you need on an existing Kubernetes cluster
