Updating Instance Placement in an Instance Pool
Update the location where the instances in an instance pool are placed. The placement includes the availability domains, fault domains, and subnets for the instances in the instance pool.
When you remove an availability domain from an instance pool, the pool permanently deletes all of its instances in that availability domain. The pool replaces the instances with new instances in the availability domains that are still associated with the pool.
Use the instance-pool update command to update the placement for an instance pool.
oci compute-management instance-pool update --instance-pool-id <INSTANCE_POOL_OCID> --placement-configurations <file://path/to/file.json>
<file://path/to/file.json> is the path to a JSON file that defines the placement configurations. For information about how to generate an example of the JSON file, see Advanced JSON Options.
For a complete list of flags and variable options for the Compute Service CLI commands, see the command line reference for Compute.
Use the UpdateInstancePool operation to update the placement for an instance pool.
