Multi-client interop scripts

Startup scripts for multiclient interop testnet. Currently only the scripts for nimbus and lighthouse have been kept up-to-date.

Kubernetes any topology cluster

Spin cluster with helm

If you need a kubernetes local cluster use kind - Optional

https://kind.sigs.k8s.io/docs/user/quick-start/

GO111MODULE="on" go get sigs.k8s.io/[email protected]
kind create cluster

Setup helm

kubectl create serviceaccount --namespace kube-system tiller
kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin --serviceaccount=kube-system:tiller
helm init --service-account tiller

Load images (only if you use kind) - Optional

Images are available on dockerhub actually, they are built daily, so this is completely optional

cd scripts

docker build --target multinet-nimbus -t eth2clients/multinet-nimbus .
kind load docker-image multinet-nimbus --name kind

docker build --target multinet-lighthouse -t eth2clients/multinet-lighthouse .
kind load docker-image multinet-lighthouse --name kind

docker build --target multinet-prysm -t eth2clients/multinet-prysm .
kind load docker-image multinet-prysm --name kind

Finally start the cluster

Customize multinet-cluster/values.yaml

helm install ./multinet-cluster  

Using a development slot

Nimbus basic example

NIMBUS_DEV_NODES must be more then 0 in values.yaml

Also set the local persistent path NIMBUS_SOURCE_PATH

  1. kubectl exec --stdin --tty nimbus-dev-0 -- /bin/bash
  2. cd nimbus-src
  3. make update
  4. source env.sh
  5. export NIMFLAGS="-d:insecure -d:metrics -d:libp2p_expensive_metrics -d:chronicles_log_level=TRACE -d:chronicles_colors=off --warnings:off --hints:off --opt:speed -d:const_preset=/root/multinet/repo/data/testnet/config.yaml"
  6. nim c -o:beacon_node $NIMFLAGS beacon_chain/beacon_node
  7. ./beacon_node --finalized-checkpoint-state:/root/multinet/repo/data/testnet/genesis.ssz --bootstrap-file=/root/multinet/repo/data/testnet/bootstrap_nodes.txt --log-file=nimbus.log --data-dir=/root/multinet/repo/deposits/nimbus-dev-0 --log-level="DEBUG;TRACE:switch" --metrics

Running just 3 nodes with docker-compose

cd scripts
docker-compose up

Inspecting the source

Use the respective docker volumes, just simply attach from another container e.g.:

docker run -it --rm -v nimbus-source:/tmp/nimbus ubuntu bash

Using this trick you could even attach via visual studio code and SSH integration.

Known issues

For some reason (due to the build.rs in deposit_contract project) lighthouse will need to build again (we built already in the Dockerfile...) the first time docker-compose up will run.
