This script is used to generate token for a given pulsar role.
|
|
Options:
|
|
-h,--help prints the usage message
|
|
-n,--namespace the k8s namespace to install the pulsar helm chart
|
|
-k,--release the pulsar helm release name
|
|
-r,--role the pulsar role
|
|
-s,--symmetric use symmetric secret key for generating the token. If not provided, the private key of an asymmetric pair of keys is used.
|
|
-l,--local read and write output from local filesystem, do not install secret to kubernetes
|

Usage:
|

$0 --namespace pulsar --release pulsar-dev -c <pulsar-role>
