delete

Description

Removes a backend server from a given network load balancer and backend set.

Usage

oci nlb backend delete [OPTIONS]

Required Parameters

--backend-name [text]

The name of the backend server to remove. If the backend was created with an explicitly specified name, that name should be used here. If the backend was created without explicitly specifying the name, but was created using ipAddress, this is specified as <ipAddress>:<port>. If the backend was created without explicitly specifying the name, but was created using targetId, this is specified as <targetId>:<port>.

Example:

10.0.0.3:8080` or `ocid1.privateip..oc1.<var>&lt;unique_ID&gt;</var>:8080
--backend-set-name [text]

The name of the backend set associated with the backend server.

Example:

example_backend_set
--network-load-balancer-id [text]

The OCID of the network load balancer to update.

Optional Parameters

--force

Perform deletion without prompting for confirmation.

--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

--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 current etag value of the resource.

--max-wait-seconds [integer]

The maximum time to wait for the work request to reach the state defined by --wait-for-state. Defaults to 1200 seconds.

--wait-for-state [text]

This operation asynchronously creates, modifies or deletes a resource and uses a work request to track the progress of the operation. Specify this option to perform the action and then wait until the work request reaches a certain 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:

ACCEPTED, CANCELED, CANCELING, FAILED, IN_PROGRESS, SUCCEEDED
--wait-interval-seconds [integer]

Check every --wait-interval-seconds to see whether the work request has reached the 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.
