Migrate vaultwarden docker compose to kubernetes

[KeyPerformanceGroup]

Hi team,

I actualy have an up to date vaultwarden installed with docker compose.

I have sevreal users, and a liscence for an organisation.

Is their any easy solution to migrate this installation to this helm chart version ?

Thank you for your help.

I have sevreal users, and a liscence for an organisation.

I don't believe that Vaultwarden has any licensing mechanism, from anything that I've seen. It just exists.

I'm going to assume that since you're using Docker Compose, you're using SQLite as the database backend. In my Kubernetes environment, I'm using Postgres. I followed this guide from the Vaultwarden app wiki to migrate my database over, used the Helm chart and used my values file to point towards the new database, using a temporary value for domain and ingress.hostname until I performed a full checkout of the application and ensure that the data appears to be intact.

A redacted version of my values.yaml file is below:

bump: 0
image:
  pullPolicy: Always
domain: "https://vault.[REDACTED]/"
websocket:
  enabled: true
  address: "0.0.0.0"
  port: 3012
rocket:
  port: 8080
  workers: 10
webVaultEnabled: true
adminToken:
  existingSecret: "awssm-vaultwarden-prod"
  existingSecretKey: "vaultwarden-admin-token"
hibpApiKey: "[REDACTED]"
signupDomains: "[REDACTED]"
signupsVerify: true
showPassHint: true
ingress:
  enabled: true
  class: "nginx"
  tlsSecret: vaultwarden-tls
  hostname: vaultwarden.[REDACTED]
  nginxIngressAnnotations: false
  additionalHostnames:
    - vault.[REDACTED]
  additionalAnnotations:
    cert-manager.io/cluster-issuer: "letsencrypt"
database:
  type: postgresql
  existingSecret: "awssm-vaultwarden-prod"
  existingSecretKey: "VAULTWARDEN_DB_URL_DIRECT"
smtp:
  existingSecret: "awssm-vaultwarden-prod"
  from: "vaultwarden@[REDACTED]"
  host: "smtp.[REDACTED]"
  security: "starttls"
  port: 587
  fromName: "Vaultwarden"
  authMechanism: "Login"
  username:
    existingSecretKey: "smtp-api-username"
  password:
    existingSecretKey: "smtp-api-token"

Hope this helps!
