Superset

You can deploy an instance of Superset with your Hydrolix cluster. Superset is an open-source data exploration and visualization platform that allows users to query, visualize, and analyze data ingested into Hydrolix.

Deploy Superset

To deploy Superset into your cluster, add the following to your hydrolixcluster.yaml

data_visualization_tools:
- superset

Hydrolix should deploy two additional pods:

superset-xxxxxxxxxx-xxxxx
superset-init-db-xx-x-x-xxxxx

Superset is exposed at the superset.hostname.hydrolix.live subdomain. Accessing this URL requires a DNS wildcard record (*.hostname.hydrolix.live) and a wildcard certificate for Traefik.

Superset network configuration

Create a DNS record

Set the following environment variable:

export HDX_KUBERNETES_NAMESPACE={your-k8s-namespace}

Run the following command to retrieve the Traefik record:

kubectl get service/traefik --namespace=$HDX_KUBERNETES_NAMESPACE

You should see output similar to the following:

NAME          TYPE           CLUSTER-IP       EXTERNAL-IP                                                                     PORT(S)                                AGE                                                                          8089/TCP                               68m
traefik       LoadBalancer   10.64.14.42    34.66.136.134   80:31708/TCP,9000:32344/TCP            2m50s

Use the DNS provider of your choice. Set up an A record for your hostname that points to the EXTERNAL-IP from the response.

Key	Value
Record name	*.hostname.hydrolix.live
Record type	A
Value	34.66.136.134

Install a wildcard certificate

Use the instructions in Hydrolix ACME Client to for automated wildcard certificate. provisioning This requires the use of AWS Route53 as an authoritative DNS provider.

Use Provision Certificate Manually to install a wildcard certificate procured directly from a Certification Authority.

Use Superset

The Superset instance is now accessible. To visit it in your web browser, go to https://superset.hostname.hydrolix.live.

Login using your standard Hydrolix credentials. You should be redirected automatically to https://superset.hostname.hydrolix.live/superset/welcome/.

Deactivate Superset

Remove Superset from your cluster by deleting the deployment setting from your Hydrolix configuration. Delete these two lines:

data_visualization_tools:
- superset

When the change is applied, your Hydrolix installation will remove the two additional Superset pods. If you like, remove the DNS settings described in Create a DNS record.

Note that even though the Superset service is disabled, the internal configuration for Superset will persist in the Hydrolix database. If you later decide to re-enable Superset, the previous configuration will take effect.
