reth config

Write config to stdout

$ reth config --help

Usage: reth config [OPTIONS]

Options:
      --config <FILE>
          The path to the configuration file to use.

      --default
          Show the default config

      --chain <CHAIN_OR_PATH>
          The chain this node is running.
          
          Possible values are either a built-in chain or the path to a chain specification file.
          
          Built-in chains:
          - mainnet
          - goerli
          - sepolia
          
          [default: mainnet]

      --instance <INSTANCE>
          Add a new instance of a node.
          
          Configures the ports of the node to avoid conflicts with the defaults. This is useful for running multiple nodes on the same machine.
          
          Max number of instances is 200. It is chosen in a way so that it's not possible to have port numbers that conflict with each other.
          
          Changes to the following port numbers: - DISCOVERY_PORT: default + `instance` - 1 - AUTH_PORT: default + `instance` * 100 - 100 - HTTP_RPC_PORT: default - `instance` + 1 - WS_RPC_PORT: default + `instance` * 2 - 2
