Compartments

Basics

• A compartment is a collection of related resources. It helps you organize, isolate, and control access to your resources.

• To create a compartment:

• OCI Console → Identity → Compartment.

• Compartments can be nested up to six levels deep

• Sub compartments inherit access permission from compartments upper its hierarchy.

• Each resource belongs to a single compartment

• Resources can interact even when they are located in different compartments

• Resources can be moved from one compartment to another.

• Resources from different regions can be in the same compartment

• Can give a group of users access to compartment using policies

• Best practices: Create dedicated compartments when you need to isolate resources.

• 

Root compartment

• The root compartment can hold all the cloud resource

Compartment Quotas

• Compartment Quotas similar to Service Limits; the biggest difference is that service limits are set by Oracle, and compartment quotas are set by administrators using policies.

• Three types of quota policies

• Set: sets the maximum number of a cloud resource that can be used for a compartment.

• Unset: resets quota to the default service limits.

• Zero: removes access to a cloud resource for a compartment.

• Example

• Zero compute quotas /*bm*/ in tenancy

• Set compute quota /*bm*/ to 5 in tenancy where request.region= us-phoenix-1

Compartment Explorer

• OCI Console → Governance → Compartment Explorer.

• Allow you to see all resources created under a specific compartment
