Documentation     Verify Helm functionality on multiple Kubernetes versions.
...
...               Fresh new kind-based clusters will be created for each
...               of the Kubernetes versions being tested. An existing
...               kind cluster can be used by specifying it in an env var
...               representing the version, for example:
...
...                  export KIND_CLUSTER_1_16_1="helm-ac-keepalive-1.16.1"
...                  export KIND_CLUSTER_1_15_4="helm-ac-keepalive-1.15.4"
...                  export KIND_CLUSTER_1_14_7="helm-ac-keepalive-1.14.7"
