update

Description

Updates the configuration of the specified steering policy.

Usage

oci dns steering-policy update [OPTIONS]

Required Parameters

--steering-policy-id [text]

The OCID of the target steering policy.

Optional Parameters

--answers [complex type]

The set of all answers that can potentially issue from the steering policy.

This option is a JSON list with items of type SteeringPolicyAnswer. For documentation on SteeringPolicyAnswer please see our API reference: https://docs.cloud.oracle.com/api/#/en/dns/20180115/datatypes/SteeringPolicyAnswer. 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.

--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 for the steering policy. Does not have to be unique and can be changed. 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/Content/API/SDKDocs/cliusing.htm#AdvancedJSONOptions

--health-check-monitor-id [text]

The OCID of the health check monitor providing health data about the answers of the steering policy. A steering policy answer with rdata matching a monitored endpoint will use the health data of that endpoint. A steering policy answer with rdata not matching any monitored endpoint will be assumed healthy.

Note: To use the Health Check monitoring feature in a steering policy, a monitor must be created using the Health Checks service first. For more information on how to create a monitor, please see Managing Health Checks.

--if-match [text]

The If-Match header field makes the request method conditional on the existence of at least one current representation of the target resource, when the field-value is *, or having a current representation of the target resource that has an entity-tag matching a member of the list of entity-tags provided in the field-value.

--if-unmodified-since [text]

The If-Unmodified-Since header field makes the request method conditional on the selected representation’s last modification date being earlier than or equal to the date provided in the field-value. This field accomplishes the same purpose as If-Match for cases where the user agent does not have an entity-tag for the representation.

--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.

--rules [complex type]

The series of rules that will be processed in sequence to reduce the pool of answers to a response for any given request.

The first rule receives a shuffled list of all answers, and every other rule receives the list of answers emitted by the one preceding it. The last rule populates the response.

This option is a JSON list with items of type SteeringPolicyRule. For documentation on SteeringPolicyRule please see our API reference: https://docs.cloud.oracle.com/api/#/en/dns/20180115/datatypes/SteeringPolicyRule. 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.

--scope [text]

Specifies to operate only on resources that have a matching DNS scope.

Accepted values are:

GLOBAL, PRIVATE
--template [text]

A set of predefined rules based on the desired purpose of the steering policy. Each template utilizes Traffic Management’s rules in a different order to produce the desired results when answering DNS queries.

Example: The FAILOVER template determines answers by filtering the policy’s answers using the FILTER rule first, then the following rules in succession: HEALTH, PRIORITY, and LIMIT. This gives the domain dynamic failover capability.

It is strongly recommended to use a template other than CUSTOM when creating a steering policy.

All templates require the rule order to begin with an unconditional FILTER rule that keeps answers contingent upon answer.isDisabled != true, except for CUSTOM. A defined HEALTH rule must follow the FILTER rule if the policy references a healthCheckMonitorId. The last rule of a template must must be a LIMIT rule. For more information about templates and code examples, see Traffic Management API Guide.

Template Types

  • FAILOVER - Uses health check information on your endpoints to determine which DNS answers to serve. If an endpoint fails a health check, the answer for that endpoint will be removed from the list of available answers until the endpoint is detected as healthy.

  • LOAD_BALANCE - Distributes web traffic to specified endpoints based on defined weights.

  • ROUTE_BY_GEO - Answers DNS queries based on the query’s geographic location. For a list of geographic locations to route by, see Traffic Management Geographic Locations.

  • ROUTE_BY_ASN - Answers DNS queries based on the query’s originating ASN.

  • ROUTE_BY_IP - Answers DNS queries based on the query’s IP address.

  • CUSTOM - Allows a customized configuration of rules.

Accepted values are:

CUSTOM, FAILOVER, LOAD_BALANCE, ROUTE_BY_ASN, ROUTE_BY_GEO, ROUTE_BY_IP
--ttl [integer]

The Time To Live (TTL) for responses from the steering policy, in seconds. If not specified during creation, a value of 30 seconds will be used.

--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:

ACTIVE, CREATING, DELETED, DELETING
--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 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.
