Welcome to the forum.

Please become accustomed to provide decent context info of your problem.
It is always helpful to support a request with system info like OS and shell, related environment (variables, options), preferred tools, adequate (representative) sample input and desired output data and the logics connecting the two, and, if existent, system (error) messages verbatim, to avoid ambiguities and keep people from guessing.

I'm pretty sure you won't "curl with these variables:", so please provide complete commands so people don't need to guess what you're doing or want to do. To read, expand, and use data from files, try
Code:
while read A B C D E; do echo "{ \"nodename\": \"$A\", \"ipaddress\": \"$B\", \"poolname\": \"$C\", \"port\": \"$D\", \"loadbalancer\" : \"$E\" }"; done < input_file.txt
{ "nodename": "server001", "ipaddress": "10.10.10.01", "poolname": "serverpool1", "port": "80", "loadbalancer" : "loadbalancer01" }
{ "nodename": "server002", "ipaddress": "10.10.10.02", "poolname": "serverpool1", "port": "80", "loadbalancer" : "loadbalancer01" }
{ "nodename": "server003", "ipaddress": "10.10.10.03", "poolname": "serverpool1", "port": "80", "loadbalancer" : "loadbalancer01" }

nodename

nodename(4)							   File Formats 						       nodename(4)

NAME

       nodename - local source for system name

SYNOPSIS

       /etc/nodename

DESCRIPTION

       When  a	machine is standalone or its IP address is configured locally, the /etc/nodename file contains the system name. By convention, the
       system name is the same as the hostname associated with the IP address of the primary network interface, for example, hostname.hme0.

       If the machine's network configuration is delivered by the RPC bootparams protocol, the /etc/nodename file is not used, as the system  name
       is delivered by the remote service.

       Given a system name value, regardless of source, the uname utility invoked with the -S option is used to set the system name of the running
       system.

       If the machine's network configuration is delivered by the DHCP protocol, the /etc/nodename file is used only if the DHCP server  does  not
       provide a value for the Hostname option (DHCP standard option code 12).

       A system name configured in /etc/nodename should be unique within the system's name service domain in order to ensure that any network ser-
       vices provided by the system will operate correctly.

       Given a system name value, regardless of source, the uname utility invoked with the -S option is used to set the system name of the running
       system.

EXAMPLES

       Example 1 Syntax

       The syntax for nodename consists of a single line containing the system's name. For example, for a system named myhost:

	 myhost
