Oracle Cloud Infrastructure Documentation

Creating an Instance Pool

Instance pools give you the ability to provision and create multiple Compute instances based off of the same configuration, within the same region. For more information about instance pools and instance configurations, see Managing Compute Instances.

Optionally, you can associate a load balancer with an instance pool. If you do this, when you add an instance to the instance pool, the instance is automatically added to the load balancer's A logical entity defined by a list of backend servers, a load balancing policy, and a health check policy. . After the instance reaches a healthy state (the instance is listening on the configured port number), incoming traffic is automatically routed to the new instance. For background information about the Load Balancing service, see Overview of Load Balancing.

Warning

Avoid entering confidential information when assigning descriptions, tags, or friendly names to your cloud resources through the Oracle Cloud Infrastructure Console, API, or CLI.

Required IAM Policy

To use Oracle Cloud Infrastructure, you must be given the required type of access in a An IAM document that specifies who has what type of access to your resources. It is used in different ways: to mean an individual statement written in the policy language; to mean a collection of statements in a single, named "policy" document (which has an Oracle Cloud ID (OCID) assigned to it); and to mean the overall body of policies your organization uses to control access to resources. written by an administrator, whether you're using the Console or the REST API with an SDK, CLI, or other tool. If you try to perform an action and get a message that you don’t have permission or are unauthorized, confirm with your administrator the type of access you've been granted and which A collection of related resources that can be accessed only by certain groups that have been given permission by an administrator in your organization. you should work in.

For administrators: For a typical policy that gives access to instance pools and instance configurations, see Let users manage Compute instance configurations, instance pools, and cluster networks.

Prerequisites

Before you can create an instance pool, you need:

Note

You cannot create an instance pool from an instance configuration where the image source is a boot volume.

Using the Console

You can create an instance pool from the Instance Configuration Details page or from the Instance Pools page.

Using the API

For information about using the API and signing requests, see REST APIs and Security Credentials. For information about SDKs, see Software Development Kits and Command Line Interface.

Use these API operations to create and manage instance pools:
