./full_start.sh {clusterName} [chaincodeVersion]

Delete a cluster

With the persistent data:

./delete_cluster.sh {clusterName}

Start only the cluster

./start_cluster.sh {clusterName}

Select cluster for kubectl

kubectl config use-context kind-{clusterName}

• uc4-lagom, every service of Lagom
• uc4-support, supporting container like imaginary
• hlf, everything from Hyperledger
