A validator can be exited with following command:

lighthouse --network "$chain" account validator exit --keystore /path/to/keystore --password-file "$HOME/exit/keystore-password.txt" --beacon-node http://localhost:5052

Where:

--network is mainnet for Ethereum chain and gnosis for Gnosis chain
--keystore is a path to the keystore file of specific validator
--password-file is a file with exit passowrd placed in
--beacon-node is a beaconnode url

Example request can look as below:

/usr/local/bin/lighthouse --network mainnet account validator exit --keystore /var/lib/lighthouse/vi1/validators/keystore... --beacon-node http://localhost:5052

/usr/local/bin/lighthouse --network gnosis account validator exit --keystore /var/lib/lighthouse/vi1/validators/keystore... --beacon-node http://localhost:5052

For confirmation, place exit phrase Exit my validator

Follow instructions from Exit Lighthouse validators on Github.

Install a script for bulk exit
Create ~/exit/keystore-password.txt file with keystores password. It's the passowrd selected during validator keys generation. The passowrd can be also found at validator_definitions.yml file, see
```
sudo nano /var/lib/lighthouse-validatorInstance/validator_definitions.yml
```

Perform the exit all validators in selected instance request

/usr/local/bin/lighthouse_exit_validators.sh mainnet /var/lib/ethereum/lighthouse/vi1/validators http://localhost:5052

/usr/local/bin/lighthouse_exit_validators.sh gnosis /var/lib/gnosis/lighthouse/vi1/validators http://localhost:5052

Replace chain for ethereum / gnosis
Replace /var/lib/gnosis/lighthouse/vi1/validators/ for a path to your instance keystores

Remove the password from ~/exit/keystore-password.txt
