Configure Function Mesh Operator

When you install the Function Mesh Operator through the Helm chart, you can apply its configurations through the command flag. For example, if you want to enable pprof for the Function Mesh Operator, set the controllerManager.pprof.enable to true.

helm install <release_name> function-mesh/function-mesh-operator -n <k8s_namespace> \
  --set controllerManager.pprof.enable=true
