DESCRIPTION

Adds a backend server to a backend set.

USAGE

oci lb backend create [OPTIONS]

REQUIRED PARAMETERS

--backend-set-name [text]

    The name of the backend set to add the backend server to.

    Example:

    example_backend_set

--ip-address [text]

    The IP address of the backend server.

    Example:

    10.0.0.3

--load-balancer-id [text]

    The OCID <https://docs.cloud.oracle.com/Content/General/Concepts/identifiers.htm> of the load balancer associated with the backend set and servers.

--port [integer]

    The communication port for the backend server.

    Example:

    8080

OPTIONAL PARAMETERS

--backup [boolean]

    Whether the load balancer should treat this server as a backup unit. If true, the load balancer forwards no ingress traffic to this backend server unless all other backend servers not marked as “backup” fail the health check policy.

    Note: You cannot add a backend server marked as backup to a backend set that uses the IP Hash policy.

    Example:

    false

--drain [boolean]

    Whether the load balancer should drain this server. Servers marked “drain” receive no new incoming traffic.

    Example:

    false

--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

--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.

--offline [boolean]

    Whether the load balancer should treat this server as offline. Offline servers receive no incoming traffic.

    Example:

    false

--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, FAILED, IN_PROGRESS, SUCCEEDED

--wait-interval-seconds [integer]

    Check every --wait-interval-seconds to see whether the work request to see if it has reached the state defined by --wait-for-state. Defaults to 30 seconds.

--weight [integer]

    The load balancing policy weight assigned to the server. Backend servers with a higher weight receive a larger proportion of incoming traffic. For example, a server weighted ‘3’ receives 3 times the number of new connections as a server weighted ‘1’. For more information on load balancing policies, see How Load Balancing Policies Work <https://docs.cloud.oracle.com/Content/Balance/Reference/lbpolicies.htm>.

    Example:

    3

GLOBAL PARAMETERS

Use oci --help for help on global parameters.

--auth-purpose, --auth, --cert-bundle, --cli-rc-file, --config-file, --debug, --defaults-file, --endpoint, --generate-full-command-json-input, --generate-param-json-input, --help, --latest-version, --max-retries, --no-retry, --opc-client-request-id, --opc-request-id, --output, --profile, --query, --raw-output, --region, --release-info, --request-id, --version, -?, -d, -h, -v

EXAMPLES

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

    oci lb load-balancer create --generate-param-json-input subnet-ids > subnet-ids.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 <https://docs.oracle.com/en-us/iaas/Content/API/SDKDocs/cliinstall.htm#configfile> and appropriate security policies <https://docs.oracle.com/en-us/iaas/Content/Identity/Concepts/policygetstarted.htm> before trying the examples.
