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

Creates a new load balancer in the specified compartment. For general
information about load balancers, see Overview of the Load Balancing
Service.

For the purposes of access control, you must provide the OCID of the
compartment where you want the load balancer to reside. Notice that
the load balancer doesn’t have to be in the same compartment as the
VCN or backend set. If you’re not sure which compartment to use, put
the load balancer in the same compartment as the VCN. For information
about access control and compartments, see Overview of the IAM
Service.

You must specify a display name for the load balancer. It does not
have to be unique, and you can change it.

For information about Availability Domains, see Regions and
Availability Domains. To get a list of Availability Domains, use the
*ListAvailabilityDomains* operation in the Identity and Access
Management Service API.

All Oracle Cloud Infrastructure resources, including load balancers,
get an Oracle-assigned, unique ID called an Oracle Cloud Identifier
(OCID). When you create a resource, you can find its OCID in the
response. You can also retrieve a resource’s OCID by using a List API
operation on that resource type, or by viewing the resource in the
Console. Fore more information, see Resource Identifiers.

After you send your request, the new object’s state will temporarily
be PROVISIONING. Before using the object, first make sure its state
has changed to RUNNING.

When you create a load balancer, the system assigns an IP address. To
get the IP address, use the GetLoadBalancer operation.


Usage
=====

   oci lb load-balancer create [OPTIONS]


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

--compartment-id, -c [text]

The OCID of the compartment in which to create the load balancer.

--display-name [text]

changeable. Avoid entering confidential information.

Example:

   example_load_balancer

--shape-name [text]

A template that determines the total pre-provisioned bandwidth
(ingress plus egress). To get a list of available shapes, use the
ListShapes operation.

Example:

--subnet-ids [complex type]

An array of subnet OCIDs. 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.

(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.

   Examples

======================================================================

When creating a load balancer, there are two main options:

* Providing all information when calling the "create" command

* Providing minimal information to the "create" command then then
  using individual commands to “assemble” the load balancer post-
  creation

Working samples for both approaches can be found here.


Providing all information at create time
----------------------------------------

Under this option, you would call the "create" command and specify the
"--certificates", "--backend-sets", "--listener" and "--path-route-
sets" options in order to also create these items when creating the
load balancer. Since those options are complex types, it is
recommended that you place their input in JSON files and then specify
these files as input to the command using the file:// syntax. For
example:

   oci lb load-balancer create --backend-sets file://path/to/backend/set/file.json

You can discover the format of the input you need to provide by using
the "--generate-param-json-input" option. For example:

   oci lb load-balancer create --generate-param-json-input certificates
   oci lb load-balancer create --generate-param-json-input backend-sets
   oci lb load-balancer create --generate-param-json-input listeners
   oci lb load-balancer create --generate-param-json-input path-route-sets

As an alternative to providing those individal options, you can
specify all the input to the command in a single file using the "--
from-json" option. For example:

   oci lb load-balancer create --from-json file://path/to/file/of/input.json

You can discover the format of the input you need to provide by using
the "--generate-full-command-json-input" option. For example:

   oci lb load-balancer create --generate-full-command-json-input


Providing minimal information and then assembling via other commands
--------------------------------------------------------------------

Under this option, you would only supply the mandatory arguments to
the "create" command (and not any of the input marked as "COMPLEX
TYPE") and then use other operations to add certificates, backend
sets, listeners and path route sets. This approach is more applicable
if you do not wish to prepare JSON input files.

The key commands you’ll need to be aware of are:

* This command

* Create certificate

* Create backend set

* Create backend

* List protocols

* Create listener

* Create path route set

You would tie these together in sequence by:

   # Create load balancer with minimal attributes
   oci lb load-balancer create

   # Create a certificate bundle associated with the load balancer (call command multiple times if needed)
   oci lb certificate create

   # Create a backend set associated with the load balancer (call command multiple times if needed)
   # You may need the details of the certificate you previously created
   oci lb backend-set create

   # Add multiple backends to the backend set
   oci lb backend create
   oci lb backend create

   # Create a path route set for a particular listener of the load balancer to route traffic to appropriate back-end set
   oci lb path-route-set create

   # Add a listener to the load balancer (call command multiple times if needed)
   # This will take a --protocol option, whose valid values you can discover by oci lb protocol lists
   # You may also need the details of the certificate you previously created
   oci lb listener create

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 and appropriate
security policies before trying the examples.
