AltostratusCan I run TMSH commands inside an iRule?
I have added: set NODENAME [HTTP::header value test] POOLMEMBER_IP=($(tmsh list ltm node $NODENAME | grep "address" | awk '{print $2}')) 1) I am trying to run tmsh commands using/i...
Hello Mahanth.
I think you are mixing concepts. Take into account this:
- TMSH are management plane scripts
- iRule are dataplane scripts.
So, you cannot access a F5 config using iRule commands.
One idea that you could use is to resolv your server hostname using your DNS.

NimbostratusPlease note that with v15 RESOLV::lookup is deprecated and no longer supported!

deprecated just means it is marked for removal in a future version. As long as it's still available it will be supported.
- Rene_C_
Trust me, with v15 you dont want to use that anymore, unless you are ready for core dumps....
I guess you mean this:

It's a problem with the object name resolution, but it has workaround.
- Rene_C_
Yeah, thats the one we raised. And it has a workaround but its not so easy to implement depending on the environment you have, since we have a complete custom dev cycle for irules. But, well.
- JRahm
Ok fair enough, Rene! 😃
But generally, deprecated doesn't mean immediate death sentence. Test, test, then test some more, and as I recommend with any new release, comb the release notes and if there is a better way forward with any implementation, iterate through those updates as resources allows.
