-h,--help prints the usage message
|
|
-n,--namespace the k8s namespace to install the pulsar helm chart
|
|
-k,--release the pulsar helm release name
|
|
-s,--symmetric generate symmetric secret key. If not provided, an asymmetric pair of keys are generated.
|
|
-l,--local read and write output from local filesystem, do not install secret to kubernetes
|

$0 --namespace pulsar --release pulsar-dev
