Download this file to your local computer and open it in a text editor. You can use the template yaml file as a starting point to create your own custom PostgreSQL server yaml file. To create a PostgreSQL server, you need to create a Kubernetes secret to store your postgres administrator login and password securely and a PostgreSQL server custom resource based on the postgresqls custom resource definitions. The examples in this article will use kubectl, but similar approaches could be used with other Kubernetes tools such as the Kubernetes dashboard, oc, or helm if you are familiar with those tools and Kubernetes yaml/json. To create a PostgreSQL server using Kubernetes tools, you will need to have the Kubernetes tools installed. You should have already created a data controller. The latest updates are available in the release notes. You can find out more about the postgresclusters custom resource definition through the documentation and through kubectl explain, i.e.As a preview feature, the technology presented in this article is subject to Supplemental Terms of Use for Microsoft Azure Previews.

If you are on the same network as your PostgreSQL cluster, you can connect directly to it using the following command: Connect via psql in the Terminal Connect Directly You can also choose to bring your own PKI / certificate authority this is covered later in the documentation. PGO sets up a public key infrastructure (PKI) for your Postgres clusters.
