Ssl with metabase helm chart

HI ,

i was looking to install the metabase as a helm chart and enable ssl on it.
looking at https://github.com/helm/charts/tree/master/stable/metabase - i see in the values.yaml we need to pass in ssl.keyStore in jks format .

ssl:

If you have an ssl certificate and would prefer to have Metabase run over HTTPS

enabled: false

port: 8443

keyStore: |-

<< JKS KEY STORE >>

keyStorePassword: storepass

does the configuration should be a binary or the value of it (keytool -list -v -keystore mykeystore.jks)
i have tried both and it doesnt work
request some help here?
