Create LTM Virtuals

[CodeCentral_194]

Problem this snippet solves:

This example shows how to automate virtual server creation with tmsh scripting.

How to use this snippet:

Note: This was used in conjunction with a simple iRule just to create HTTP responders for another LTM system. The iRule is very simple:

when HTTP_REQUEST {
  HTTP::respond 200 content "

[IP::local_addr]" }

Code :

cli script create_virtuals.tcl {

proc script::run {} {
    if { $tmsh::argc < 4 } {
       puts "Requires three arguments:   "
       exit
   } else {
       set start [lindex $tmsh::argv 1]
       set total [lindex $tmsh::argv 2]
       set rulename [lindex $tmsh::argv 3]
   }
   scan $start "%d.%d.%d.%d:%d" a b c d p
   for {set x 0} {$x < $total} {incr x} {
       tmsh::create ltm virtual testvip_$x destination $a.$b.$c.$d:$p profiles add \{http\} rules \{$rulename\}
       incr d
       if { $d > 255 } {
           set d 0
           incr c
           if { $c > 255 } {
               set c 0
               incr b
               if { $b > 255 } {
                   set b 0
                   incr a
               }
           }
       }
    }
}

proc script::help {} {
    tmsh::add_help "Create contiguous block of virtual servers as HTTP responders\n\
         " 
}
