PostgreSQL

Usage example¶

Example

apiVersion: aiven.io/v1alpha1
kind: PostgreSQL
metadata:
  name: my-postgresql
spec:
  authSecretRef:
    name: aiven-token
    key: token

  connInfoSecretTarget:
    name: postgresql-secret
    prefix: MY_SECRET_PREFIX_
    annotations:
      foo: bar
    labels:
      baz: egg

  project: aiven-project-name
  cloudName: google-europe-west1
  plan: startup-4

  maintenanceWindowDow: sunday
  maintenanceWindowTime: 11:00:00

  userConfig:
    pg_version: "15"

Info

To create this resource, a Secret containing Aiven token must be created first.

Apply the resource with:

kubectl apply -f example.yaml

Verify the newly created PostgreSQL:

kubectl get postgresqls my-postgresql

The output is similar to the following:

Name             Project               Region                 Plan         State      
my-postgresql    aiven-project-name    google-europe-west1    startup-4    RUNNING

To view the details of the Secret, use the following command:

kubectl describe secret postgresql-secret

You can use the jq to quickly decode the Secret:

kubectl get secret postgresql-secret -o json | jq '.data | map_values(@base64d)'

The output is similar to the following:

{
    "POSTGRESQL_HOST": "<secret>",
    "POSTGRESQL_PORT": "<secret>",
    "POSTGRESQL_DATABASE": "<secret>",
    "POSTGRESQL_USER": "<secret>",
    "POSTGRESQL_PASSWORD": "<secret>",
    "POSTGRESQL_SSLMODE": "<secret>",
    "POSTGRESQL_DATABASE_URI": "<secret>",
    "POSTGRESQL_CA_CERT": "<secret>",
}
