Docker images

Docker images are available from Docker Hub .

We have version-specific Docker tags (statusim/nimbus-eth2:amd64-v1.2.3) and a tag for the latest image (statusim/nimbus-eth2:amd64-latest).

These images are simply the contents of release tarballs inside a debian:bullseye-slim image, running under a user imaginatively named user, with UID:GID of 1000:1000.

The unpacked archive is in /home/user/nimbus-eth2 which is also the default WORKDIR. The default ENTRYPOINT is the binary itself: /home/user/nimbus-eth2/build/nimbus_beacon_node

Usage

Before running Nimbus via docker, you need to prepare a data directory and mount it in docker.

It is recommended that you mount the directory at /home/user/nimbus-eth2/build/data and pass --data-dir=build/data/shared_mainnet_0 to all nimbus_beacon_node commands.

The wrapper script outlined below will set the data directory automatically.

mkdir data
docker run -it --rm \
  -v ${PWD}/data:/home/user/nimbus-eth2/build/data \
  statusim/nimbus-eth2:amd64-latest \
  --data-dir=build/data/shared_mainnet_0
  --network=mainnet [other options]

Wrapper script

If you wish, you can choose to use a wrapper script instead:

mkdir data
docker run -it --rm \
  -v ${PWD}/data:/home/user/nimbus-eth2/build/data \
  --entrypoint /home/user/nimbus-eth2/run-mainnet-beacon-node.sh \
  statusim/nimbus-eth2:amd64-latest [other options]

Docker compose

Our preferred setup is using docker-compose. You can use one of our example configuration files as a base for your own custom configuration:

mkdir data
docker-compose -f docker-compose-example1.yml up --quiet-pull --no-color --detach

Note

The rather voluminous logging is done on stdout, so you might want to change the system-wide Docker logging defaults (which dumps everything in /var/lib/docker/containers/CONTAINER_ID/CONTAINER_ID-json.log) to something like syslog. We recommend using a log rotation system with appropriate intervals for logs of this size.
