Azure PostgreSQL

Create an integration to manage access to Azure-managed PostgreSQL databases

PostgreSQL databases are open-source relational database management systems emphasizing extensibility and SQL compliance. Microsoft enables developers to create cloud-hosted PostgreSQL databases.

Through this integration, Apono helps you securely manage access to your Azure PostgreSQL instances.

To enable Apono to manage Azure PostgreSQL user access, you must create a user and then configure the integration within the Apono UI.

Prerequisites

Item	Description
Apono Connector	On-prem connection serving as a bridge between an Azure MySQL database instance and Apono Minimum Required Version: 1.3.0
PostgreSQL Info	Information for the database instance to be integrated: Hostname Port Number Database Name

Create a PostgreSQL user

You must create a user in your PostgreSQL instance for the Apono connector and grant that user permissions to your databases.

You must use the admin account and password to connect to your database.

Use the following steps to create a user and grant it permissions:

1. In your preferred client tool, create a new user. Use apono_connector for the username. Be sure to set a strong password for the user. You must also grant the azure_pg_admin role to the user in the database instance.

CREATE USER apono_connector WITH ENCRYPTED PASSWORD 'password';
ALTER USER apono_connector WITH CREATEROLE;
GRANT azure_pg_admin TO apono_connector;

2. Grant privileges to the azure_pg_admin role on all databases except template0 and azure_sys. This allows Apono to perform tasks that are not restricted to a single schema or object within the database, such as creating, altering, and dropping database objects.

DO $$
DECLARE
  database_name text;
BEGIN
  FOR database_name IN (SELECT datname FROM pg_database WHERE datname != 'template0' AND datname != 'azure_sys' AND datname != 'azure_maintenance') LOOP
    EXECUTE 'GRANT ALL PRIVILEGES ON DATABASE ' || quote_ident(database_name) || ' TO azure_pg_admin WITH GRANT OPTION';
  END LOOP;
END; $$

3. For each database to be managed through Apono, connect to the database and grant azure_pg_admin privileges on all objects in the schemas. This allows Apono to perform tasks that are restricted to schemas within the database, such as modifying table structures, creating new sequences, or altering functions.\

DO $$
DECLARE
  schema text;
BEGIN
  FOR schema IN (SELECT schema_name FROM information_schema.schemata WHERE schema_name NOT LIKE 'pg_%' AND schema_name != 'information_schema' AND schema_name != 'cron') LOOP
    EXECUTE 'GRANT ALL PRIVILEGES ON SCHEMA ' || quote_ident(schema) || ' TO azure_pg_admin WITH GRANT OPTION';
    EXECUTE 'GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA ' || quote_ident(schema) || ' TO azure_pg_admin WITH GRANT OPTION';
    EXECUTE 'GRANT ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA ' || quote_ident(schema) || ' TO azure_pg_admin WITH GRANT OPTION';
    EXECUTE 'GRANT ALL PRIVILEGES ON ALL FUNCTIONS IN SCHEMA ' || quote_ident(schema) || ' TO azure_pg_admin WITH GRANT OPTION';
  END LOOP;
  EXECUTE 'ALTER DEFAULT PRIVILEGES GRANT ALL PRIVILEGES ON TABLES TO azure_pg_admin WITH GRANT OPTION';
  EXECUTE 'ALTER DEFAULT PRIVILEGES GRANT ALL PRIVILEGES ON SEQUENCES TO azure_pg_admin WITH GRANT OPTION';
  EXECUTE 'ALTER DEFAULT PRIVILEGES GRANT ALL PRIVILEGES ON FUNCTIONS TO azure_pg_admin WITH GRANT OPTION';
  EXECUTE 'ALTER DEFAULT PRIVILEGES GRANT ALL PRIVILEGES ON SCHEMAS TO azure_pg_admin WITH GRANT OPTION';
END; $$

4. Connect to the template1 database and grant azure_pg_admin privileges on all objects in the schemas. For any new databases created in the future, this allows Apono to perform tasks that are restricted to schemas within the database, such as modifying table structures, creating new sequences, or altering functions.

DO $$
DECLARE
  schema text;
BEGIN
  FOR schema IN (SELECT schema_name FROM information_schema.schemata WHERE schema_name NOT LIKE 'pg_%' AND schema_name != 'information_schema' AND schema_name != 'cron') LOOP
    EXECUTE 'GRANT ALL PRIVILEGES ON SCHEMA ' || quote_ident(schema) || ' TO azure_pg_admin WITH GRANT OPTION';
    EXECUTE 'GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA ' || quote_ident(schema) || ' TO azure_pg_admin WITH GRANT OPTION';
    EXECUTE 'GRANT ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA ' || quote_ident(schema) || ' TO azure_pg_admin WITH GRANT OPTION';
    EXECUTE 'GRANT ALL PRIVILEGES ON ALL FUNCTIONS IN SCHEMA ' || quote_ident(schema) || ' TO azure_pg_admin WITH GRANT OPTION';
  END LOOP;
  EXECUTE 'ALTER DEFAULT PRIVILEGES GRANT ALL PRIVILEGES ON TABLES TO azure_pg_admin WITH GRANT OPTION';
  EXECUTE 'ALTER DEFAULT PRIVILEGES GRANT ALL PRIVILEGES ON SEQUENCES TO azure_pg_admin WITH GRANT OPTION';
  EXECUTE 'ALTER DEFAULT PRIVILEGES GRANT ALL PRIVILEGES ON FUNCTIONS TO azure_pg_admin WITH GRANT OPTION';
  EXECUTE 'ALTER DEFAULT PRIVILEGES GRANT ALL PRIVILEGES ON SCHEMAS TO azure_pg_admin WITH GRANT OPTION';
END; $$

5. Using the credentials from step 1, create a secret for the database instance and associate it to the Azure connector.

Integrate Azure PostgreSQL

Follow these steps to complete the integration:

1. On the Catalog tab, click Azure PostgreSQL. The Connect Integration page appears.

2. Under Discovery, click one or more resource types to sync with Apono.

Apono automatically discovers and syncs all the instances in the environment. After syncing, you can manage Access Flows to these resources.

3. Click Next. The Apono connector section appears.

4. From the dropdown menu, select the connector that has been granted read access to the secret for the PostgreSQL instance.

If the desired connector is not listed, click + Add new connector and follow the instructions for creating an Azure connector and associate the secret with the connector.

5. Click Next. The Integration Config section expands.

6. Define the Integration Config settings.

   Setting	Description
   Integration Name	Unique, alphanumeric, user-friendly name used to identify this integration when constructing an access flow
   Hostname	Hostname of the PostgreSQL instance to connect
   Port	Port value for the database By default, Apono sets this value to 5432.
   Database Name	Name of the database to integrate By default, Apono sets this value to postgre.
   SSL Mode	(Optionl) Mode of Secure Sockets Layer (SSL) encryption used to secure the connection with the SQL database server Option Description require An SSL-encrypted connection must be used. allow An SSL-encrypted or unencrypted connection is used.

    Custom Access Details	(Optional) Instructions explaining how to access this integration's resources Upon accessing an integration, a message with these instructions will be displayed to end users in the User Portal. The message may include up to 400 characters. To view the message as it appears to end users, click Preview. NOTE: You can also add the custom_access_details parameter to the apono_integration schema using Terraform. For more information, learn how to integrate with Apono in the Terraform Registry.
    Integration Owner	(Optional) Fallback approver if no resource owner is found Follow these steps to define one or several integration owners: From the Attribute dropdown menu, select User or Group under the relevant identity provider (IdP) platform. From the Value dropdown menu, select one or multiple users or groups. NOTE: When Resource Owner is defined, an Integration Owner must be defined.
    Resource Owner	(Optional) Group or role responsible for managing access approvals or rejections for the resource Follow these steps to define one or several resource owners: Enter a Key name. This value is the name of the tag created in your cloud environment. From the Attribute dropdown menu, select an attribute under the IdP platform to which the key name is associated. Apono will use the value associated with the key (tag) to identify the resource owner. When you update the membership of the group or role in your IdP platform, this change is also reflected in Apono. NOTE: When this setting is defined, an Integration Owner must also be defined.
11. Click Confirm.

Now that you have completed this integration, you can create access flows that grant permission to your Azure PostgreSQL instances.
