usage: $0 [OPTIONS] [cluster entry point hostname]
Start a validator with no stake
OPTIONS:
--ledger PATH - store ledger under this PATH
--init-complete-file FILE - create this file, if it doesn't already exist, once node initialization is complete
--label LABEL - Append the given label to the configuration files, useful when running
multiple validators in the same workspace
--node-sol SOL - Number of SOL this node has been funded from the genesis config (default: $node_sol)
--no-voting - start node without vote signer
--rpc-port port - custom RPC port for this node
--no-restart - do not restart the node if it exits
--no-airdrop - The genesis config has an account for the node. Airdrops are not required.
