Strimzi operator gets OOMKilled in Kind and Minikube. #4547
Description
Describe the bug
After deploying the Kafka cluster using ./hack/run.sh deploy-kafka the Strimzi operator gets OOMKilled after a while and then every few minutes.
The number of nodes not matter and if it is Kind or Minikube. It fails on both.
Here is a kubectl -n kafka describe pod strimzi-cluster-operator-... excerpt:

Readiness: http-get http://:http/ready delay=10s timeout=1s period=30s #success=1 #failure=3Expected behavior
The Strimzi operator is expected to run without being OOMKilled.
To Reproduce
- Create Kind or Minikube cluster with one or multiple nodes.
- Important: Deploy
cert-manager=> either manually from the eventing repositorythird_party/cert-manager/*OR via./hack/run.sh deploy-infra=> it will deploy Eventing, Kafka and publish test images. - If you used
./hack/run.sh deploy-infrayou're done, now just wait and it will start to crash after a while. If you deployed the cert-manager manually run./hack/run.sh deploy-kafkato deploy the Kafka cluster and then wait again a bit.
