Ich versuche Cassandra auf kubernetes laufen zu lassen.Ich kann Cassandra auf Kubernetes nicht ausführen
Eine Sache, die ich verstanden habe, ist Cassandra versucht, auf kubernetes api-Server auf port 443 (Secure Connection) zugreifen, aber ich bin api Server auf non secure connection port 8080 ausgeführt.
Auch ist es Has no permission to create /cassandra_data/data directory Fehler
Error (Cassandra pod log):
