Create a PostgreSQL service

Apply the following object on your namespace, as specified by its YAML description.

Example to create a PostgreSQL instance

apiVersion: vshn.appcat.vshn.io/v1
kind: VSHNPostgreSQL
metadata:
  name: pgsql-app1-prod (1)
  namespace: prod-app (2)
spec:
  parameters:
    service:
      majorVersion: "16" (3)
      pgBouncerSettings: (4)
        pgbouncer:
          admin_users: postgres
      pgSettings:
        timezone: Europe/Zurich (5)
    size: (6)
      plan: plus-4
    backup: (7)
      schedule: "30 23 * * *"
      retention: 12
  writeConnectionSecretToRef:
    name: postgres-creds (8)

1	Instance name
2	The namespace where the object will be created
3	PostgreSQL version. For supported versions, see our product docs
4	Specify additional configuration to the pgBouncer instance [optional]. See documentation
5	Specify custom PostgreSQL settings [optional]
6	Size of the PostgreSQL instance. See Plans and Sizing for more information.
7	Backup configuration, `schedule` standard cron: en.wikipedia.org/wiki/Cron, `retention` field specify how many backups should be kept
8	Secret where the connection details are provisioned. This secret shouldn’t exist before creation.

To get more information about all available configuration options, please see the API Reference

Inspect your new PostgreSQL service

$  kubectl get vshnpostgresqls.vshn.appcat.vshn.io
NAME              SYNCED   READY   CONNECTION-SECRET   AGE
pgsql-app1-prod   True     True    postgres-creds      6m14s

When you see True in the READY column, it means the instance is provisioned and ready to use.

Find the connection details

The connection details are stored in a secret. You can retrieve them with the following command:

$ oc get secrets postgres-creds -o yaml

The output of the command above is a secret specification with the following structure:

apiVersion: v1
kind: Secret
metadata:
  name: postgres-creds
stringData:
  POSTGRESQL_DB: postgres (1)
  POSTGRESQL_HOST: my-postgres-example.my-cloud.com (2)
  POSTGRESQL_PASSWORD: my-secret (3)
  POSTGRESQL_PORT: 21699 (4)
  POSTGRESQL_URL: postgres://postgres:my-secret@my-postgres-example.my-cloud.com:21699/postgresql?sslmode=require (5)
  POSTGRESQL_USER: postgres (6)
  ca.crt: base64encoded(data) (7)
  tls.crt: base64encoded(data) (8)
  tls.key: base64encoded(data) (9)

1	Database name
2	Host to connect to
3	Password
4	Port
5	URL containing all necessary information to connect to the instance
6	Username
7	ca.crt to use when using `sslmode=verify-full`
8	tls.crt to use when connecting to instance
9	tls.key to use when connecting to instance
