PostgreSQL Primary

PostgreSQL Container Example

This example starts a single PostgreSQL container and service, the most simple of examples.

The container creates a default database called userdb, a default user called testuser and a default password of password.

For all environments, the script additionally creates:

• A persistent volume claim
• A crunchy-postgres container named primary
• The database using predefined environment variables

And specifically for the Kubernetes and OpenShift environments:

• A pod named primary
• A service named primary
• A PVC named primary-pgdata
• The database using predefined environment variables

To shutdown the instance and remove the container for each example, run the following:

./cleanup.sh

Docker

To create the example and run the container:

cd $CCPROOT/examples/docker/primary
./run.sh

Connect from your local host as follows:

psql -h localhost -U testuser -W userdb

Kubernetes and OpenShift

To create the example:

cd $CCPROOT/examples/kube/primary
./run.sh

Connect from your local host as follows:

psql -h primary -U postgres postgres
