Examples

The examples show configuration files for setting up your PostgreSQL cluster.

Basics

Basic cluster

cluster-example.yaml A basic example of a cluster.

Custom cluster

cluster-example-custom.yaml A basic cluster that uses the default storage class and custom parameters for the postgresql.conf and pg_hba.conf files.

Cluster with customized storage class

cluster-storage-class.yaml: A basic cluster that uses a specified storage class of standard.

Cluster with persistent volume claim (PVC) template configured

cluster-pvc-template.yaml: A basic cluster with an explicit persistent volume claim template.

Extended configuration example

cluster-example-full.yaml: A cluster that sets most of the available options.

Bootstrap cluster with SQL files

cluster-example-initdb-sql-refs.yaml: A cluster example that executes a set of queries defined in a secret and a ConfigMap right after the database is created.

Sample cluster with customized pg_hba configuration

cluster-example-pg-hba.yaml: A basic cluster that enables the user app to authenticate using certificates.

Sample cluster with Secret and ConfigMap mounted using projected volume template

cluster-example-projected-volume.yaml A basic cluster with the existing Secret and ConfigMap mounted into Postgres pod using projected volume mount.

Backups

Customized storage class and backups

Prerequisites: Bucket storage must be available. The sample config is for AWS. Change it to suit your setup.

cluster-storage-class-with-backup.yaml A cluster with backups configured.

Backup

Prerequisites: cluster-storage-class-with-backup.yaml applied and healthy.

backup-example.yaml: An example of a backup that runs against the previous sample.

Simple cluster with backup configured

Prerequisites: The configuration assumes minio is running and working. Update backup.barmanObjectStore with your minio parameters or your cloud solution.

cluster-example-with-backup.yaml A basic cluster with backups configured.

Replica clusters

Replica cluster by way of backup from an object store

Prerequisites: cluster-storage-class-with-backup.yaml applied and healthy, and a backup cluster-example-trigger-backup.yaml applied and completed.

cluster-example-replica-from-backup-simple.yaml: A replica cluster following a cluster with backup configured.

Replica cluster by way of volume snapshot

Prerequisites: cluster-example-with-volume-snapshot.yaml applied and healthy, and a volume snapshot backup-with-volume-snapshot.yaml applied and completed.

cluster-example-replica-from-volume-snapshot.yaml: A replica cluster following a cluster with volume snapshot configured.

Replica cluster by way of streaming (pg_basebackup)

Prerequisites: cluster-example.yaml applied and healthy.

cluster-example-replica-streaming.yaml: A replica cluster following cluster-example with streaming replication.

PostGIS

PostGIS example

postgis-example.yaml: An example of a PostGIS cluster. See PostGIS for details.

Managed roles

Cluster with declarative role management

cluster-example-with-roles.yaml: Declares a role with the managed stanza. Includes password management with Kubernetes secrets.

Managed services

Cluster with managed services

cluster-example-managed-services.yaml: Declares a service with the managed stanza. Includes default service disabled and new rw service template of LoadBalancer type defined.

Declarative tablespaces

Cluster with declarative tablespaces

cluster-example-with-tablespaces.yaml

Cluster with declarative tablespaces and backup

Prerequisites: The configuration assumes minio is running and working. Update backup.barmanObjectStore with your minio parameters or your cloud solution.

cluster-example-with-tablespaces-backup.yaml

Restored cluster with tablespaces from object store

Prerequisites: The previous cluster applied and a base backup completed. Remember to update bootstrap.recovery.backup.name with the backup name.

cluster-restore-with-tablespaces.yaml

For a list of available options, see API reference.

Pooler configuration

Pooler with custom service config

pooler-external.yaml
