Options:
|
|
-h,--help prints the usage message
|
|
-n,--namespace the k8s namespace to install the pulsar helm chart. Defaut to ${namespace}.
|
|
-k,--release the pulsar helm release name. Default to ${release}.
|
|
-d,--dir the dir for storing tls certs. Default to ${tlsdir}.
|
|
-c,--client-components the client components of pulsar cluster. a comma separated list of components. Default to ${clientComponents}.
|
|
-s,--server-components the server components of pulsar cluster. a comma separated list of components. Default to ${serverComponents}.
|
|
-l,--local read and write output from local filesystem, do not install secret to kubernetes
