Graph Protocol Chart Bundle

Helm chart deploying 4 Graph Protocol Charts: - Graph Protocol Agent - Graph Protocol Index Node - Graph Protocol Query Node - Graph Protocol Service


$ helm repo add vulcanlink
$ helm install my-release vulcanlink/graphprotocol


This chart bootstraps a graphprotocol deployment on a Kubernetes cluster using the Helm package manager.

Vulcan Link charts can be used with Kubeapps for deployment and management of Helm Charts in clusters.


  • Kubernetes 1.12+
  • Helm 2.12+ or Helm 3.0-beta3+
  • PV provisioner support in the underlying infrastructure


Before installing the Graph Protocol chart you should setup the necessary secrets. Secrets are used to store sensitive configuration info. Non-sensitive configuration info can be stored in ConfigMaps. The Graph Protocol chart bundle requires 3 secrets: - Docker Secret - Postgres Secret - Mnemonic Secret

Docker Secret

This secret is used to access private docker repos using authentification. See the example file at docker.yaml. Once you have added your credentials to the secret apply it as such:

kubectl apply -f docker.yaml

Postgres Secret

This secret is used to access your Postgres server. See the example file at postgres-credentials.yaml. The Graph Protocol chart assumes that the graph, index-agent, and index-service databases are all hosted on the same Postgres server requiring the same auth info. Once you have added the host and password values to the secret apply it as such:

kubectl apply -f postgres-credentials.yaml

Mnemonic Secret

This secret is used to set your Ethereum Mnemonic from which the indexer-agent and indexer-service derive their signing keys. See the example file at ethereum-accounts.yaml. Once you have added the mnemonic value to the secret apply it as such:

kubectl apply -f ethereum-accounts.yaml

Installing the Chart

To install the chart with the release name my-release:

$ helm install my-release vulcanlink/graphprotocol

The command deploys graphprotocol on the Kubernetes cluster in the default configuration. The Parameters section lists the parameters that can be configured during installation.

Tip: List all releases using helm list

Uninstalling the Chart

To uninstall/delete the my-release deployment:

$ helm delete my-release


The following tables lists the configurable parameters of the graphprotocol-agent chart and their default values. The only parameters listed here are whether to enable each component of the chart. Subchart-specific parameters can found in each subchart’s respective To configure subchart parameters, prefix the parameter with the subchart name. For example, to change the indexnode replica count, update graphprotocol-indexnode.replicaCount. See the example-values.yaml files for an example of configuring the subcharts.

Parameter Description Default
graphprotocol-agent.enabled Enable Graph Protocol Agent subchart true
graphprotocol-indexnode.enabled Enable Graph Protocol Index Node subchart true
graphprotocol-querynode.enabled Enable Graph Protocol Query Node subchart true
graphprotocol-service.enabled Enable Graph Protocol Service Node subchart true

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

$ helm install my-release vulcanlink/graphprotocol-agent --set graphprotocol-indexnode.enabled=false

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

$ helm install my-release -f values.yaml vulcanlink/graphprotocol-agent

Tip: You will need to update the missing subchart placeholder parameters (eg graphprotocol-indexnode.config.ethereum) for the values.yaml file. See example-values.yaml for an example.
