A validator is an Ethereum client to validate transactions and generate blocks.

Prerequisites

• StatefulSets support
• Dynamically provisioned persistent volumes

Specify each parameter using the --set key=value[,key=value] argument to helm install.

Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,

helm install \
  --name ${DEPLOYMENT_ENVIRONMENT}-validator-${NAME} \
  -f values.yaml \
  kubernetes/amis/generic/validator

Tip: You can use the default values.yaml
