ATTACHINSTSTOLOADBALANCER()`¶

About AttachInstancesToLoadBalancer¶

Attaches one or more Lightsail instances to a load balancer.

After some time, the instances are attached to the load balancer and the health check status is available.

The attach instances to load balancer operation supports tag-based access control via resource tags applied to the resource identified by load balancer name. For more information, see the Lightsail Developer Guide.

IMPORTING¶

Required arguments:¶

`iv_loadbalancername` `TYPE /AWS1/LSARESOURCENAME` `/AWS1/LSARESOURCENAME`¶

The name of the load balancer.

`it_instancenames` `TYPE /AWS1/CL_LSARESOURCENAMELIST_W=>TT_RESOURCENAMELIST` `TT_RESOURCENAMELIST`¶

An array of strings representing the instance name(s) you want to attach to your load balancer.

An instance must be running before you can attach it to your load balancer.

There are no additional limits on the number of instances you can attach to your load balancer, aside from the limit of Lightsail instances you can create in your account (20).

RETURNING¶

`oo_output` `TYPE REF TO /aws1/cl_lsaattachinststoloa01` `/AWS1/CL_LSAATTACHINSTSTOLOA01`¶

Domain /AWS1/RT_ACCOUNT_ID

Primitive Type NUMC

Syntax Example¶

This is an example of the syntax for calling the method. It includes every possible argument and initializes every possible value. The data provided is not necessarily semantically accurate (for example the value "string" may be provided for something that is intended to be an instance ID, or in some cases two arguments may be mutually exclusive). The syntax shows the ABAP syntax for creating the various data structures.

DATA(lo_result) = lo_client->attachinststoloadbalancer(
  it_instancenames = VALUE /aws1/cl_lsaresourcenamelist_w=>tt_resourcenamelist(
    ( new /aws1/cl_lsaresourcenamelist_w( |string| ) )
  )
  iv_loadbalancername = |string|
).

This is an example of reading all possible response values

lo_result = lo_result.
IF lo_result IS NOT INITIAL.
  LOOP AT lo_result->get_operations( ) into lo_row.
    lo_row_1 = lo_row.
    IF lo_row_1 IS NOT INITIAL.
      lv_nonemptystring = lo_row_1->get_id( ).
      lv_resourcename = lo_row_1->get_resourcename( ).
      lv_resourcetype = lo_row_1->get_resourcetype( ).
      lv_isodate = lo_row_1->get_createdat( ).
      lo_resourcelocation = lo_row_1->get_location( ).
      IF lo_resourcelocation IS NOT INITIAL.
        lv_string = lo_resourcelocation->get_availabilityzone( ).
        lv_regionname = lo_resourcelocation->get_regionname( ).
      ENDIF.
      lv_boolean = lo_row_1->get_isterminal( ).
      lv_string = lo_row_1->get_operationdetails( ).
      lv_operationtype = lo_row_1->get_operationtype( ).
      lv_operationstatus = lo_row_1->get_status( ).
      lv_isodate = lo_row_1->get_statuschangedat( ).
      lv_string = lo_row_1->get_errorcode( ).
      lv_string = lo_row_1->get_errordetails( ).
    ENDIF.
  ENDLOOP.
ENDIF.
