Update an Instance Pool
put
/20160918/instancePools/{instance_pool_id}
Update the specified instance pool. You can change the name of the pool, the size of the pool, the instance configuration that is used to create new instances, the fault domains, VCN, and subnet. Configuration changes do not affect existing instances; configuration changes only affect new instances. New instances will be provisioned using the new instance configuration and placement configuration.
To attach or detach an instance, see AttachInstancePoolInstance and DetachInstancePoolInstance.
To attach load balancers or detach load balancer attachments, see AttachLoadBalancer and DetachLoadBalancer.
Request
Supported Media Types
- application/json
Path Parameters
-
instancePoolId(required): string
The OCID of the instance pool.
Header Parameters
-
if-match: string
For optimistic concurrency control. In the PUT or DELETE call for a resource, set the if-match parameter to the value of the etag from a previous GET or POST response for that resource. The resource will be updated or deleted only if the etag you provide matches the resource's current etag value.
-
opc-retry-token: string
Minimum Length:
1
Maximum Length:64
A token that uniquely identifies a request so it can be retried in case of a timeout or server error without risk of executing that same action again. Retry tokens expire after 24 hours, but can be invalidated before then due to conflicting operations (for example, if a resource has been deleted and purged from the system, then a retry of the original creation request may be rejected).
