Troubleshooting Lodestar

Using Kubernetes

"Unknown arguments error"

Lodestar reads all environment variables prefixed with LODESTAR and will try to parse them similar to command line arguments, meaning any unknown argument will cause an error.

✖ Unknown arguments: servicePort, servicePortEthConsensusP2p,
port9000Tcp, port9000TcpPort, port9000TcpProto, port9000TcpAddr, serviceHost

The extra arguments are present because Kubernetes automatically adds environment variables to the Pod based on the name (metadata.name) defined in the associated Service. To resolve the issue, this name has to be changed to something that does not start with lodestar.
