Nimbus

Note

Nimbus includes both nimbus (base install) and nimbus_beacon inventory groups. The base role installs the binary and creates the JWT secret; the beacon role deploys the systemd service. The beacon role depends on the base role having run first.

Warning

The nimbus_jwt_secret in .credentials.yml is required and must match the secret used by the paired execution client.

Nimbus is a lightweight Ethereum consensus client (beacon node) developed by Status.

For additional information see Nimbus official docs

Deployment Vars

Secrets

nimbus_jwt_secret:

• Required

• Must match the JWT secret used by the execution layer (Geth, Nethermind, etc.)

• Generate with: openssl rand -hex 32 | tr -d "\n"

Host variables

None required.

Configuration File

The beacon.service systemd unit in /host_vars/files controls the beacon node flags, including --network, --data-dir, --web3-url, --jwt-secret, and --suggested-fee-recipient. Edit that file before deploying to set the correct execution client URL and fee recipient address.
