Bulk management of pools...

So this is more of the same questions concerning my tons of apps with the same pool members. I have written a pretty basic tmsh script that creates my applications for me which has become a lifesaver! Now I have to be able to figure out a way to change all my pools easily without the use of the GUI.

 

When I started creating the applications I grouped them together by name so I have TFA Test Fast Application and PFA Prod Fast Application. So when my script creates the monitor it

 

creates TFA-[appname]-port

 

then it creates TFA-[appname]_pool

 

then it creates TFA-[virtualhost]

 

So all the names come together as TFA or PFA. What I need to do is add and remove nodes from all the pools easily. Any ideas on this? I know I can use the modify pool command but how about a way to say modify pool "TFA-*-pool and it will change all the pools at once. Or a way to use the list command to say list all the TFA pools and push them through a modify command. I wrote a quick script that prompts what pool do you want to change and I added the ip changes to the script, but if I try to answer the prompt with TFA-*-pool it says something about not being able to use it. Putting in the name works but once I have 50 - 100 pools this isn't going to be a solution. I need to be able to script this.

 

Any help would be greatly appreciated!

 

Thank you as always!

    How about a shell script that creates the list of desired pool members and lets you loop through them. Something like the following: 

    
! /bin/bash
output=$(tmsh list ltm pool |grep "ltm pool" | awk -F" " '{ print $3 }' |grep TFA-*)
for LINE in ${output}; do
   echo ${LINE}
    process each TFA pool in this loop
done

    Kevin, you rock!

     

    So then just do a while loop that takes the output from that script and runs it through a tmsh modify command?

     

     

    Thanks so much!

    You're already in a for loop, so each iteration through will have the name of one of the TFA-* pools.
