Description

This repo defines Nimbus cluster infrastructure.

Endpoints

These are Beacon API endpoints intended for community testing.

Endpoint	Host
http://unstable.mainnet.beacon-api.nimbus.team/	linux-01.ih-eu-mda1.nimbus.mainnet
http://testing.mainnet.beacon-api.nimbus.team/	linux-02.ih-eu-mda1.nimbus.mainnet
http://unstable.sepolia.beacon-api.nimbus.team/	linux-01.ih-eu-mda1.nimbus.sepolia
http://testing.holesky.beacon-api.nimbus.team/	geth-01.ih-eu-mda1.nimbus.holesky
http://unstable.holesky.beacon-api.nimbus.team/	geth-02.ih-eu-mda1.nimbus.holesky

These nodes have no validators attached.

There are also archives of ERA files:

Endpoint	Host
https://mainnet.era.nimbus.team/	linux-03.ih-eu-mda1.nimbus.mainnet
https://sepolia.era.nimbus.team/	linux-01.ih-eu-mda1.nimbus.sepolia
https://holesky.era.nimbus.team/	geth-01.ih-eu-mda1.nimbus.holesky

Dashboards

The fleet catalog can be seen at: https://fleets.nimbus.team/

There's a dedicated Kibana dashboard for Nimbus fleet logs: https://nimbus-logs.infra.status.im/

There are explorers available for various testnets:

• https://mainnet.beaconcha.in/
• https://sepolia.beaconcha.in/
• https://holesky.beaconcha.in/

Fleet Layouts

The fleet layout configuration used by Ansible can be found in ansible/vars/layout.

But for finding which host holds which validator use TSV files in ansible/files/layout.

Bootstrap Nodes

Some nodes in this repo are used as bootstrap nodes for testnets and mainnet.

Currently this includes:

Host	IP
bootstrap-01.aws-eu-central-1a.nimbus.mainnet	3.120.104.18
bootstrap-02.aws-eu-central-1a.nimbus.mainnet	3.64.117.223

They are recorded in the eth2-networks repository.

Repo Usage

Simplest way to run commands on fleets if you have SSH access:

 > ./foreach.sh nimbus-mainnet-small "sudo systemctl --no-block restart 'build-beacon-node-*'"
stable-small-01.aws-eu-central-1a.nimbus.mainnet
stable-small-02.aws-eu-central-1a.nimbus.mainnet
