Operand images for CloudNativePG containing PostgreSQL with TimescaleDB and PostGIS
Immutable Application Containers for all available PostgreSQL versions (12 to 16) + TimescaleDB + PostGIS to be used as operands with the CloudNativePG operator for Kubernetes.
These images are built on top of the PostGIS image (Debian version), by adding the following software:
- TimescaleDB
- Barman Cloud
- PGAudit
Barman Cloud is distributed by EnterpriseDB under the GNU GPL 3 License.
PGAudit is distributed under the PostgreSQL License.
Images are available via the GitHub Container Registry.
The following example shows how you can easily create a new PostgreSQL 14
cluster with TimescaleDB 2.10 and PostGIS 3.3 in it. All you have to do is set the imageName
accordingly. Please look at the registry for a list of available images
and select the one you need.
Create a YAML manifest. For example, you can put the YAML below into a file
named timescaledb-postgis.yaml (any name is fine). (Please refer to
CloudNativePG for details on the API):
apiVersion: postgresql.cnpg.io/v1
kind: Cluster
metadata:
name: cluster-example
spec:
instances: 1
imageName: ghcr.io/imusmanmalik/timescaledb-postgis:14-3.3
bootstrap:
initdb:
postInitTemplateSQL:
- CREATE EXTENSION timescaledb;
- CREATE EXTENSION postgis;
- CREATE EXTENSION postgis_topology;
- CREATE EXTENSION fuzzystrmatch;
- CREATE EXTENSION postgis_tiger_geocoder;
postgresql:
shared_preload_libraries:
- timescaledb
storage:
size: 1GiThen run kubectl apply -f timescaledb-postgis.yaml.
When the cluster is up, run the following command to verify the version of
PostGIS that is available in the system, by connecting to the app database:
kubectl exec -ti cluster-example-1 -- psql app
Defaulted container "postgres" out of: postgres, bootstrap-controller (init)
psql (14.7 (Debian 14.7-1.pgdg110+1))
Type "help" for help.

(2 rows)The following command shows the extensions installed in the app database,
thanks to the postInitTemplateSQL section in the bootstrap which runs the
selected CREATE EXTENSION commands in the template1 database, which is
inherited by the application database - called app and created by default by
CloudNativePG.
