Obol DVT - Goerli Only
Testnet only!
If you are already running an Execution Client (EC) e.g. Geth and a Beacon Node (BN) e.g. Lighthouse you can connect your Obol DVT node to them. This allows you to reuse existing hardware and continue to run your solo staking validator alongside Obol DVT validators.
On your existing Beacon Node, ensure these flags are added so the Charon client can communicate directly.
Lighthouse Flags
Teku Flags
Nimbus Flags
--http
--http-address=0.0.0.0
--http-port=5052
--rest-api-enabled=true
--rest-api-interface=0.0.0.0
--rest-api-host-allowlist=*
--rest=true
--rest-port=5052
--rest-address=0.0.0.0
--rest-allow-origin=*
# Clone this repo
git clone https://github.com/ObolNetwork/charon-distributed-validator-node.git
# Change directory
cd charon-distributed-validator-node
There are three steps needed to change the configuration:
Copy the sample
.env file.cp .env.sample .env
Uncomment (remove the
#) the line CHARON_BEACON_NODE_ENDPOINTS. Add your existing Beacon Node IP address, for example "http://192.168.1.8:5052". As the Charon Client is running inside a Docker container you can't use localhost, even though might be running on the same physical machine, it requires the IP address of the host machine..env
...
# Connect to one or more external beacon nodes. Use a comma separated list excluding spaces.
CHARON_BEACON_NODE_ENDPOINTS="http://<EXISTING_BEACON_NODE_IP_ADDRESS>:<PORT>"
...
Any uncommented section will automatically override the same section in
docker-compose.yml when run with docker-compose up. This allows you to edit the variables used by Docker without changing the docker-compose.yml which could be modified in future updates.cp docker-compose.override.yml.sample docker-compose.override.yml
Edit the newly copied file
docker-compose.override.yml and uncomment (remove the #) the following lines:services:geth:profiles: [disable]
lighthouse:profiles: [disable]
docker-compose.override.yml
...
services:
geth:
#Disable geth
profiles: [disable]
# Bind geth internal ports to host ports
#ports:
#- 8545:8545 # JSON-RPC
#- 8551:8551 # AUTH-RPC
#- 6060:6060 # Metrics
lighthouse:
#Disable lighthouse
profiles: [disable]
# Bind lighthouse internal ports to host ports
#ports:
#- 5052:5052 # HTTP
#- 5054:5054 # Metrics
...
You are now ready to start the Obol tutorial for creating an ENR and getting your new DVT validator set up!
