System requirements

Software

Requirement	Version
Juju	3.4 or later
Kubernetes	A cluster supported by Juju, with a default storage class
Superset workload	Selected by the charm track, for example 6/stable for the Superset 6 series (packaged as a rock and attached as the superset-image resource)

Superset and its backing services all run on Kubernetes, so a single Kubernetes cloud is enough.

Resource sizing

For a single-host evaluation deployment (the tutorial setup, with PostgreSQL and Redis co-located):

Resource	Minimum
CPU	2 threads, 4 recommended
RAM	8 GB
Disk	40 GB

Production sizing depends on the number of concurrent users and the query mix. Scale the UI and worker applications horizontally rather than growing a single pod, and size PostgreSQL for the metadata database and Redis for the results cache accordingly. See Scale and tune performance.

Supported dependency channels

The deployment flows in this documentation are tested with:

Charm	Channel	Required
postgresql-k8s	14/stable	Yes
redis-k8s	latest/edge	Yes
traefik-k8s or nginx-ingress-integrator	latest/stable	For ingress and TLS, over the ingress interface
self-signed-certificates	1/stable	For an HTTPS ingress URL in testing
oauth-external-idp-integrator	latest/edge	For single sign-on with an external identity provider
smtp-integrator	latest/stable	For alerts and reports
trino-k8s	latest/edge	For the Trino integration
cos-lite	latest/stable	For observability

Ports

Port	Protocol	Purpose
8088	TCP	Superset web server and API (UI)
9102	TCP	Prometheus metrics from the StatsD exporter (UI and worker)
9103	TCP	Prometheus metrics from the Celery exporter (worker)
9125	UDP	StatsD metrics ingest, in-pod (UI)
