DataRoaster

DataRoaster is open source data platform running on Kubernetes.

DataRoaster Architecture

DataRoaster has a simple architecture. There are several operators in DataRoaster to install data platform components easily.

• DataRoaster Operator handles REST requests to create custom resources.
• After creating custom resources, DataRoaster Helm Operator and other operators like DataRoaster Trino Operator and DataRoaster Spark Operator will be notified and create data platform components.

Data Platform Components supported by DataRoaster

Components supported by DataRoaster:

• Hive Metastore: standard data catalog in data lakehouses.
• Spark Thrift Server: hive server compatible interface through which hive queries will be executed on spark.
• Trino: popular query engine in data lakehouses.
• Redash: popular BI tool.
• Jupyterhub: multi-user version of jupyter notebook.
• Kafka: popular event streaming platform.
• Airflow: popular workflow.

Install DataRoaster

helm repo add dataroaster-operator https://cloudcheflabs.github.io/dataroaster-operator-helm-repo/
helm repo update;

helm install \
dataroaster-operator \
--create-namespace \
--namespace dataroaster-operator \
--version v3.0.8 \
--set image=cloudcheflabs/dataroaster-operator:4.3.0 \
--set dataroastermysql.storage.storageClass=oci \
dataroaster-operator/dataroaster-operator;

dataroastermysql.storage.storageClass is mysql storage class which needs to be replaced with one of your kubernetes cluster.

You need to copy the randomly generated admin password which will be used to access dataroaster api.

kubectl logs -f $(kubectl get pod -l app=dataroaster-operator -o jsonpath="{.items[0].metadata.name}" -n dataroaster-operator) -n dataroaster-operator | grep "randomly generated password for user";

Output looks like this.

...
randomly generated password for user 'admin': 9a87f65688a64e999e62c8c308509708
...

9a87f65688a64e999e62c8c308509708 is the temporary admin password which can be used for the first time and should be changed in the future.

To access DataRoaster from local, port-forward the service of dataroaster-operator-service.

kubectl port-forward svc/dataroaster-operator-service 8089 -n dataroaster-operator;
