Examples
========

In this section, you can find some examples of configuration files to
set up your PostgreSQL Cluster.

..  Important::
   These examples are here for demonstration and experimentation purposes, and can be executed on a personal Kubernetes cluster with Minikube or Kind as described in the  :ref:`Quickstart <Quickstart>`  .

..  Seealso::
   For a list of available options, please refer to the  :ref:`API Reference <Resource Types>`  .

Basics
------

-  \*Basic cluster*\* :

::

   apiVersion: postgresql.cnpg.io/v1
   kind: Cluster
   metadata:
     name: cluster-example
   spec:
     instances: 3

     storage:
       size: 1Gi

a basic example of a cluster.

-  \*Custom cluster*\* :

::

   apiVersion: postgresql.cnpg.io/v1
   kind: Cluster
   metadata:
     name: cluster-example-custom
   spec:
     instances: 3

     # Parameters and pg_hba configuration will be append
     # to the default ones to make the cluster work
     postgresql:
       parameters:
         max_worker_processes: "60"
       pg_hba:
         # To access through TCP/IP you will need to get username
         # and password from the secret cluster-example-custom-app
         - host all all all md5

     # Example of rolling update strategy:
     # - unsupervised: automated update of the primary once all
     #                 replicas have been upgraded (default)
     # - supervised: requires manual supervision to perform
     #               the switchover of the primary
     primaryUpdateStrategy: unsupervised

     # Require 1Gi of space per instance using default storage class
     storage:
       size: 1Gi

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*\* :

::

   apiVersion: postgresql.cnpg.io/v1
   kind: Cluster
   metadata:
     name: postgresql-storage-class
   spec:
     instances: 3

     # Example of rolling update strategy:
     # - unsupervised: automated update of the primary once all
     #                 replicas have been upgraded (default)
     # - supervised: requires manual supervision to perform
     #               the switchover of the primary
     primaryUpdateStrategy: unsupervised

     # Persistent storage configuration
     storage:
       storageClass: standard
       size: 1Gi

: a basic cluster that uses a specified storage class of ``standard`` .

-  \*Cluster with PVC Template (Persistent Volume Claim) configured*\* :

::

   apiVersion: postgresql.cnpg.io/v1
   kind: Cluster
   metadata:
     name: postgresql-pvc-template
   spec:
     instances: 3

     # Example of rolling update strategy:
     # - unsupervised: automated update of the primary once all
     #                 replicas have been upgraded (default)
     # - supervised: requires manual supervision to perform
     #               the switchover of the primary
     primaryUpdateStrategy: unsupervised

     # Persistent storage configuration
     storage:
       size: 1Gi
       pvcTemplate:
         accessModes:
           - ReadWriteOnce
         resources:
           requests:
             storage: 1Gi
         storageClassName: standard
         volumeMode: Filesystem

: a basic cluster that with an explicit persistent volume claim
template.

-  \*Extended configuration example*\* :

::

   #  Example of definition of a test cluster using all the elements available
   #  in the CRD. Please change values appropriately for your environment.
   #  Remember that you can take advantage of convention over configuration
   #  and normally you dont need to use all these definitions.
