Thanks for using PgAdmin4 Helm Chart :)

Image: {{ template "pgadmin4.image" . }}

Credentials:
  Email: {{ .Values.auth.email }}
  Password: {{ printf "kubectl get secret %s -n %s -o jsonpath='{.data.%s}' | base64 -d" (include "pgadmin4.fullname" .) .Release.Namespace .Values.auth.passwordKey }}

Ingress: {{ ternary (tpl .Values.ingress.hostname .) "DISABLED" .Values.ingress.enabled }}

GOOD LUCK!
