dbaas/v0.1.0
33e3874

dbaas/v0.1.0 is the first release: managed PostgreSQL on Harvester, with each database in its own virtual machine. It has two parts:

  • Operator: runs on the Harvester cluster as an Addon and manages DBInstance, DBSnapshot and DBRestore resources. The API is dbaas.opencloud.wso2.com/v1alpha1 and may change in later releases.
  • Rancher UI extension: create and run databases from Rancher, including snapshots, restores, OS updates and database images.

Requirements

  • Harvester 1.9.0 (the tested version), with Rancher Monitoring enabled. The operator creates a ServiceMonitor for every database.
  • A VLAN network that gives database VMs internet access on first boot.
  • The database VM images below.
  • For the UI extension: Rancher 2.15 or later (tested on 2.15.2).

Database VM images

The operator does not download images. Build them with Packer (database/images/packer) and upload them to the Harvester default namespace with exactly these names. Admins can also upload them from the UI's Database Images page.

Image Ubuntu PostgreSQL
ubuntu-2204-postgres-v20260515 22.04 (default) 15, 16, 17
ubuntu-2404-postgres-v20260701 24.04 15, 16, 17, 18

Install

  1. Upload the database VM images.
  2. On the Harvester cluster, apply the attached Addon manifest: kubectl apply -f dbaas-operator-addon.yaml. Check it with kubectl get addon dbaas-operator -n dbaas-system.
  3. In Rancher, as an admin: Extensions → ⋮ → Manage Extension Catalogs → Import Extension Catalog, using the UI extension image listed under Artifacts. Then install DBaaS from the Available tab.

For details, upgrades and uninstalling, see database/INSTALL.md.

Known limitations

  • VLAN networks only. Overlay (Kube-OVN) networks are not supported.
  • After an instance class change, max_connections keeps its old value until the next OS update (repave).
  • Prometheus can scrape PostgreSQL metrics only if the cluster's pod network can reach the database VLAN.
  • The UI offers only the operator's default instance classes and PostgreSQL versions.
