How can I find what options I can set with a `helm install` that the chart provides?

Question

Let's say I want to install an arbitrary helm chart like mysql-operator/mysql-innodbcluster how can I find what options I set with --set?

Answer 1

You can use show values to see what options the chart provides,

helm show values mysql-operator/mysql-innodbcluster

What you'll get is a YAML file, here is a part of the above YAML output,

tls:
  useSelfSigned: false
#  caSecretName:
#  serverCertAndPKsecretName:
#  routerCertAndPKsecretName:

You an set the option for useSelfSigned as tls.useSelfSigned like this:

helm install mycluster mysql-operator/mysql-innodbcluster --set tls.useSelfSigned=true
