1. For open source edition, we haven't validated the KB with K8s < 1.22, the k8s version constraints is defined in two places:
   1): kubeblocks helm chart: https://github.com/apecloud/kubeblocks/blob/main/deploy/helm/Chart.yaml
   2): preflight check in kbcli: https://github.com/apecloud/kbcli/blob/main/pkg/cmd/kubeblocks/data/kubeblocks_base_preflight.yaml
   Instead, you can install KB without kbcli, only use helm install:
   https://kubeblocks.io/docs/release-0.7/user_docs/installation/install-with-helm/install-kubeblocks-with-helm
   Remember, before the helm installation, you should follow such steps:
   1): helm fetch the KB helm chart tgz file to a local directory
   2): unzip the chart package, modify the k8s version constraint in the Chart.yaml
   3): install it new local charts with helm install
   It may work, it may not...

2. For commercial version, we can conduct a further integration and adaption with k8s 1.21, but it takes time and costs, if you are interested in it, contact with me dullboy@infracreate.com

Try 1.21 again, we have tested kubeblocks on k8s 1.21 and works well
