Hkube - cloud-native open source framework to run distributed pipeline of algorithms


$ helm repo add hkube
$ helm repo update
$ helm install hkube hkube/hkube 


This chart deploys on a Kubernetes cluster using the Helm package manager.


Hkube requires a working installation of kubernetes.
There are many options for local k8s installations. e.g Minikube or microk8s.

Hkube is installed using helm. Both helm 2 and the newer helm 3 should work.

Make sure kubectl is configured to your cluster.
For collecting algorithm logs, and to create builds, Hkube requires that certain pods will run in privileged security permissions. Consult your kubernetes installation to see how to do that. “--allow-privileged flag must be set to true for both the API server and the kubelet (or set global.isPrivileged=false)”

  • Kubernetes v1.14+
  • Dynamic storage provisioning (optional)
  • Ingress controller (optional)

Installing the Chart

To install the chart with the release name hkube:

$ helm repo add hkube
$ helm install hkube hkube/hkube

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

Tip: List all releases using helm list

Uninstalling the Chart

To uninstall/delete the hkube:

$ helm delete hkube 

The command removes all the Kubernetes components associated with the chart and deletes the release.


The following table lists the configurable parameters of the hkube chart and their default values.

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

$ helm install hkube hkube/hkube  --set global.clusterName=cluster.local

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

$ helm install hkube hkube/hkube  --values values.yaml
