# Validator Manager Import ``` Uploads validators to a validator client using the HTTP API. The validators are defined in a JSON file which can be generated using the "create-validators" command. Usage: lighthouse validator_manager import [OPTIONS] Options: --builder-boost-factor When provided, the imported validator will use this percentage multiplier to apply to the builder's payload value when choosing between a builder payload header and payload from the local execution node. --builder-proposals When provided, the imported validator will attempt to create blocks via builder rather than the local EL. [possible values: true, false] -d, --datadir Used to specify a custom root data directory for lighthouse keys and databases. Defaults to $HOME/.lighthouse/{network} where network is the value of the `network` flag Note: Users should specify separate custom datadirs for different networks. --debug-level Specifies the verbosity level used when emitting logs to the terminal. [default: info] [possible values: info, debug, trace, warn, error, crit] --gas-limit When provided, the imported validator will use this gas limit. It is recommended to leave this as the default value by not specifying this flag. --genesis-state-url A URL of a beacon-API compatible server from which to download the genesis state. Checkpoint sync server URLs can generally be used with this flag. If not supplied, a default URL or the --checkpoint-sync-url may be used. If the genesis state is already included in this binary then this value will be ignored. --genesis-state-url-timeout The timeout in seconds for the request to --genesis-state-url. [default: 180] --keystore-file The path to a keystore JSON file to be imported to the validator client. This file is usually created using staking-deposit-cli or ethstaker-deposit-cli --log-format Specifies the log format used when emitting logs to the terminal. [possible values: JSON] --logfile-debug-level The verbosity level used when emitting logs to the log file. [default: debug] [possible values: info, debug, trace, warn, error, crit] --logfile-dir Directory path where the log file will be stored --logfile-format Specifies the log format used when emitting logs to the logfile. [possible values: DEFAULT, JSON] --logfile-max-number The maximum number of log files that will be stored. If set to 0, background file logging is disabled. [default: 10] --logfile-max-size The maximum size (in MB) each log file can grow to before rotating. If set to 0, background file logging is disabled. [default: 200] --network Name of the Eth2 chain Lighthouse will sync and follow. [possible values: mainnet, gnosis, chiado, sepolia, holesky] --password Password of the keystore file. --prefer-builder-proposals When provided, the imported validator will always prefer blocks constructed by builders, regardless of payload value. [possible values: true, false] --suggested-fee-recipient When provided, the imported validator will use the suggested fee recipient. Omit this flag to use the default value from the VC. -t, --testnet-dir Path to directory containing eth2_testnet specs. Defaults to a hard-coded Lighthouse testnet. Only effective if there is no existing database. --validators-file The path to a JSON file containing a list of validators to be imported to the validator client. This file is usually named "validators.json". --vc-token The file containing a token required by the validator client. --vc-url A HTTP(S) address of a validator client using the keymanager-API. [default: http://localhost:5062] Flags: --disable-log-timestamp If present, do not include timestamps in logging output. --disable-malloc-tuning If present, do not configure the system allocator. Providing this flag will generally increase memory usage, it should only be provided when debugging specific memory allocation issues. -h, --help Prints help information --ignore-duplicates If present, ignore any validators which already exist on the VC. Without this flag, the process will terminate without making any changes. This flag should be used with caution, whilst it does not directly cause slashable conditions, it might be an indicator that something is amiss. Users should also be careful to avoid submitting duplicate deposits for validators that already exist on the VC. --log-color [] Enables/Disables colors for logs in terminal. Set it to false to disable colors. [default: true] [possible values: true, false] --log-extra-info If present, show module,file,line in logs --logfile-color Enables colors in logfile. --logfile-compress If present, compress old log files. This can help reduce the space needed to store old logs. --logfile-no-restricted-perms If present, log files will be generated as world-readable meaning they can be read by any user on the machine. Note that logs can often contain sensitive information about your validator and so this flag should be used with caution. For Windows users, the log file permissions will be inherited from the parent folder. --stdin-inputs If present, read all user inputs from stdin instead of tty. ```
