Configure your node

Validator accounts with launchpad

Please complete the steps on launchpad and store the generated files of ~/eth2.0-deposit-cli/validator_keys in ./launchpad.

1. Generate your validator(s) using launchpad and complete the process
2. Copy your generated validator(s) from ~/eth2.0-deposit-cli/validator_keys to ./launchpad
3. Create the validator password files in ./launchpad. For each validator keystore-m_123....json key file a corresponding password keystore-m_123....txt file is required. The password file will need to be named to match the correlating keystore file.

Repeat these steps as often as you like, restart your validator to make it notice your new accounts!

Validator accounts voluntary exit

1. Copy exit-account.yaml to the project's root directory (this directory)
2. Run ./teku_validator_exit.sh name-of-keystore-without-extension

For instance: If a keystore file is keystore-m_12381_3600_0_0_0-123456789.json then the command should be ./teku_validator_exit.sh keystore-m_12381_3600_0_0_0-123456789

The "Expect" needs to be installed to execute teku_validator_exit.sh. Run apt-get install expect to install expect

Run your Teku Ethereum 2.0 staking node

Start it up

Run with (as deamon with "-d")

docker-compose up -d

or run only certain services (in this case only beacon)

docker-compose up -d beacon 

Stop it

Stop services (or everything) like this

docker-compose stop beacon

Shut it down for good

Shut down your services (or everything) like this:

docker-compose down

Please note: This will also erase your logs, they are stored with your containers and will be deleted as well.

Monitoring

Logging

Docker takes care of log files and log file rotation as well as limit (set to 10x100mb log files for each service). View logs of a certain service (in this case beacon, only the last 100 lines)

docker-compose logs --tail=100 beacon

Prometheus

Runs on http://localhost:9090, scrapes data of beacon and validator.

Grafana

Grafana listens on http://localhost:3000 and uses the data provided by prometheus service.

Login with username admin and password admin (Grafana defaults), data source to Prometheus is already established and dashboards installed.

FAQ

I want to use a specific Ethereum 1 node!

Edit the line with eth1-endpoint: in ./config/teku/beacon.yaml and set your Ethereum 1 node URL, e. g. use it with Infura.io and make it look like this: eth1-endpoint: https://goerli.infura.io:443/v3/put-your-infura-id-here.
