Superset configurations are lost upon Kubernetes pod start/stop

Question

I'm having a problem with Superset on Kubernetes. After installing Superset when the pod comes down and goes up, the configurations are not saved and I lost the admin user I have created with the command:

docker exec -it superset superset fab create-admin \
           --username admin \
           --firstname Superset \
           --lastname Admin \
           --email [email protected] \
           --password admin

After that command, the only commands I used were:

$ docker exec -it superset superset db upgrade
$ docker exec -it superset superset db upgrade
$ docker exec -it superset superset init

I'm using Rancher to deploy the Superset pod. How can I persist the configurations?

Answer 1

For me I think you have two options:

1. Create a volume for your pod. Your pod definition will looks something like this (PS I didn't test this code)

apiVersion: v1
kind: Pod
metadata:
  name: pv-recycler
  namespace: default
spec:
  restartPolicy: Never
  volumes:
  - name: vol
    hostPath:
      path: /any/path/it/will/be/replaced
  containers:
  - name: pv-recycler
    image: "superset"
    command: ["/bin/sh", "superset fab", "create-admin --username admin --firstname Superset --lastname Admin --email [email protected] --password admin"]
    volumeMounts:
    - name: vol
      mountPath: /scrub

2. Make a dockerfile, add your configuration and build a new image with your configuration
