Description
===========

Update the specified instance pool.

The OCID of the instance pool remains the same.


Usage
=====

   oci compute-management instance-pool update [OPTIONS]


Required Parameters
===================

--instance-pool-id [text]

The OCID of the instance pool.


Optional Parameters
===================

--defined-tags [complex type]

Defined tags for this resource. Each key is predefined and scoped to a
namespace. For more information, see Resource Tags.

Example:

   {"Operations": {"CostCenter": "42"}}

This is a complex type whose value must be valid JSON. The value can
be provided as a string on the command line or passed in as a file
using the file://path/to/file syntax.

The "--generate-param-json-input" option can be used to generate an
example of the JSON which must be provided. We recommend storing this
example in a file, modifying it as needed and then passing it back in
via the file:// syntax.

--display-name [text]

A user-friendly name. Does not have to be unique, and it’s changeable.
Avoid entering confidential information.

--force

Perform update without prompting for confirmation.

--freeform-tags [complex type]

Free-form tags for this resource. Each tag is a simple key-value pair
with no predefined name, type, or namespace. For more information, see
Resource Tags.

Example:

   {"Department": "Finance"}

This is a complex type whose value must be valid JSON. The value can
be provided as a string on the command line or passed in as a file
using the file://path/to/file syntax.

The "--generate-param-json-input" option can be used to generate an
example of the JSON which must be provided. We recommend storing this
example in a file, modifying it as needed and then passing it back in
via the file:// syntax.

--from-json [text]

Provide input to this command as a JSON document from a file using the
file://path-to/file syntax.

The "--generate-full-command-json-input" option can be used to
generate a sample json file to be used with this command option. The
key names are pre-populated and match the command option names
(converted to camelCase format, e.g. compartment-id –> compartmentId),
while the values of the keys need to be populated by the user before
using the sample file as an input to this command. For any command
option that accepts multiple values, the value of the key can be a
JSON array.

Options can still be provided on the command line. If an option exists
in both the JSON document and the command line then the command line
specified value will be used.

For examples on usage of this option, please see our “using CLI with
advanced JSON options” link: https://docs.cloud.oracle.com/iaas/Conte
nt/API/SDKDocs/cliusing.htm#AdvancedJSONOptions

--if-match [text]

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.

--instance-configuration-id [text]

The OCID of the instance configuration associated with the instance
pool.

--instance-display-name-formatter [text]

A user-friendly formatter for the instance pool’s instances. Instance
displaynames follow the format. The formatter does not retroactively
change instance’s displaynames, only instance displaynames in the
future follow the format

--instance-hostname-formatter [text]

A user-friendly formatter for the instance pool’s instances. Instance
hostnames follow the format. The formatter does not retroactively
change instance’s hostnames, only instance hostnames in the future
follow the format

--max-wait-seconds [integer]

The maximum time to wait for the resource to reach the lifecycle state
defined by "--wait-for-state". Defaults to 1200 seconds.

--placement-configurations [complex type]

The placement configurations for the instance pool. Provide one
placement configuration for each availability domain.

To use the instance pool with a regional subnet, provide a placement
configuration for each availability domain, and include the regional
subnet in each placement configuration.

This option is a JSON list with items of type
UpdateInstancePoolPlacementConfigurationDetails.  For documentation on
UpdateInstancePoolPlacementConfigurationDetails please see our API
reference: https://docs.cloud.oracle.com/api/#/en/iaas/20160918/datat
ypes/UpdateInstancePoolPlacementConfigurationDetails. This is a
complex type whose value must be valid JSON. The value can be provided
as a string on the command line or passed in as a file using the
file://path/to/file syntax.

The "--generate-param-json-input" option can be used to generate an
example of the JSON which must be provided. We recommend storing this
example in a file, modifying it as needed and then passing it back in
via the file:// syntax.

--size [integer]

The number of instances that should be in the instance pool.

To determine whether capacity is available for a specific shape before
you resize an instance pool, use the CreateComputeCapacityReport
operation.

--wait-for-state [text]

This operation creates, modifies or deletes a resource that has a
defined lifecycle state. Specify this option to perform the action and
then wait until the resource reaches a given lifecycle state. Multiple
states can be specified, returning on the first state. For example, "
--wait-for-state" SUCCEEDED "--wait-for-state" FAILED would return on
whichever lifecycle state is reached first. If timeout is reached, a
return code of 2 is returned. For any other error, a return code of 1
is returned.

Accepted values are:

   PROVISIONING, RUNNING, SCALING, STARTING, STOPPED, STOPPING, TERMINATED, TERMINATING

--wait-interval-seconds [integer]

Check every "--wait-interval-seconds" to see whether the resource has
reached the lifecycle state defined by "--wait-for-state". Defaults to
30 seconds.

Example using required parameter
================================

Copy and paste the following example into a JSON file, replacing the
example parameters with your own.

       oci compute-management instance-configuration create --generate-param-json-input instance-details > instance-details.json

       oci compute-management instance-pool create --generate-param-json-input placement-configurations > placement-configurations.json

Copy the following CLI commands into a file named example.sh. Run the
command by typing “bash example.sh” and replacing the example
parameters with your own.

Please note this sample will only work in the POSIX-compliant bash-
like shell. You need to set up the OCI configuration and appropriate
security policies before trying the examples.
