Http class to irule conversion?

i have the same issue with pools. The config on the 11.6 is not the same as old version (10.x or 9.x) How can i convert the old config(ver 9.x or 10.x) to new config(bigip version 11.6). Is there a tool to do that?

Hi Mihai,

Thanks! fot the quick reply. But my issue is that i can't upgrade. i have a new device that i need to migrate the old config to. This is how all my http classes look like:

profile httpclass cTest80 {

defaults from httpclass

pool pTest80

paths regex "/test"

}

Hi Mihai,

when HTTP_REQUEST { 
     replace "/test" according to your specific requirements
    if { [string tolower [HTTP::uri]] starts_with "/test" } { 
         replace pool name by pool for specific application
        pool pTest80
    }
} 

Thanks, Stephan

I know how to write a http class to an irule. The problem is that i have 300 http classes . How do i convert them to irules? Is there a tool/script for this or do i have to convert them manually?

I tried search/replace too. It works only to a point. Right now i don'knoe how to move a line above the other (and do the same for 300 lines)

Thanks anyway!

Hi mihaic,

cat ./classes | tr -d "\r\n" | sed -r "s/(\})/\1\n/g" | \
sed -r -e 's/^[[:blank:]]+//g' -e 's/\}$/ }/g' | tr -s '[[:blank:]]' | \
sed -r 's/^profile httpclass ([^ ]+) \{ defaults from httpclass pool ([^ ]+) paths regex ([^ ]+) \}/ltm rule rule_\1 {\n  if { [string tolower [HTTP::uri]] starts_with \3 } {\n     pool \2\n  }\n}\n/g'

The one-liner above should convert the existing classes into iRules.

tmsh list ltm httpclass | tr -d "\r\n" | sed -r "s/(\})/\1\n/g" | \
sed -r -e 's/^[[:blank:]]+//g' -e 's/\}$/ }/g' | tr -s '[[:blank:]]' | \
sed -r 's/^profile httpclass ([^ ]+) \{ defaults from httpclass pool ([^ ]+) paths regex ([^ ]+) \}/ltm rule rule_\1 {\n  if { [string tolower [HTTP::uri]] starts_with \3 } {\n     pool \2\n  }\n}\n/g'

Output can be merged into running configuration.

Thanks! I already did it with find/replace. The only think that i needed to do manually was to move teh pool line below the elseif line.

I tried your cat command and it works. Thanks next time i'll run it and than do a couple of find/replace so i convert all those irules to one irule.

thanks a lot!!!

Hi mihaic,

when HTTP_REQUEST {
    switch -glob [string tolower [HTTP::path]] {
    "/path01*" { pool pool_app_01 }
    "/path02*" { pool pool_app_02 }
    "/path03*" { pool pool_app_03 }
    default    { pool pool_default }
    }
}

This approach is faster than testing through a long list of if/elseif/elseif/.../else conditions.
