Cluster

The DataWorkbench consists of services and background jobs in containers on a Kubernetes cluster.

The current version uses the Google Kubernetes Engine to host and manage the cluster, and Google Cloud products to provide storage, access and management.

Each component executes one or more services or tasks. The cluster configuration binds the components to the right deployment environment.

Container configuration in Docker and Kubernetes

Services and tasks will connect to resources outside the container image. We use Kubernetes' kustomize feature to pass information about the location of these resources to running containers using ConfigMaps and Secrets in Kubernetes.

The result is that the running configuration of the cluster is completely contained in a git repository. The initial setup of the cluster and backend resources still needs manual steps.
