How do I deploy a PostgreSQL role?

Setting up PostgreSQL Role

In this guide, we will walk through deploying a PostgreSQL role using Pulumi. We will define the necessary resources including the PostgreSQL provider, database, and the role itself. This example assumes you have an existing PostgreSQL instance running and are familiar with connection details required for database operations.

Overview of Resources

• Provider: This specifies connection details to a PostgreSQL instance.
• Database: Ensures the desired PostgreSQL database is available.
• Role: Creates a new role with specified privileges in the PostgreSQL database.

Here’s the complete program for setting up a PostgreSQL role:

import * as pulumi from "@pulumi/pulumi";
import * as postgresql from "@pulumi/postgresql";

const myDatabase = new postgresql.Database("my_database", {name: "exampledb"});
const myRole = new postgresql.Role("my_role", {
    name: "example_role",
    password: "examplepassword",
    login: true,
});
export const databaseName = myDatabase.name;
export const roleName = myRole.name;

Key Points

• The provider block configures the connection to your PostgreSQL instance.
• The postgresql_database resource ensures the database exampledb is created.
• The postgresql_role resource creates a new role example_role with login capability.
• Outputs are provided to easily reference the database and role names elsewhere.

Summary

We have defined a complete setup for deploying a PostgreSQL role using Pulumi. This includes configuration for the provider, the necessary database, and the role with appropriate permissions. Use these constructs to manage PostgreSQL roles efficiently in your environments.
