Class 2, Lab 3.2 - 400 Bad Request when creating pool member

[justingrantit]

Hi,

I'm having trouble getting through Class 2, Lab 3.2.

The first build script 'f5-newman-build-1' runs fine and the virtual server is built on bigip-a with no pool member.

The second build script 'f5-newman-build-2', I get a 400 Bad Request when trying to create the pool members with PATCH. I'm not sure how all these newman scripts piece together just yet so it might be user (me) error. Unfortunately, I'm not a DevOps guy (thus the training) and I'm a bit out of my depth here troubleshooting.

[justingrantit]

Should the method be POST here?

[jmcalalang]

Hey @justingrantit

This just adds the pool member into the pool, which should already be defined, the method is correct since were just modifying. Have you modified the workflows in anyway?

The Newman script calls the the Postman collection looking for step 2, which pulls you in a new token for Auth and then reuses that for added the pool members in

[justingrantit]

Yes. I can confirm that the pool is there, so PATCH isn't the issue then. Not sure why I'm getting the 400 though.

I haven't modified any of the workflows. Just following the lab guide as best I can.

[jmcalalang]

yeah you shouldnt have to modify anything past workflow 1 ( to add the other collection). you should be getting a console type output of the runner, can you copy that in here? how does it compare to the example in the guide?

[justingrantit]

Here's the bit gone wrong:

[justingrantit]

So I checked the JSON in f5-programmability-class-2.postman_collection.json and it seems to me to be escaped properly. Confusing.

[jmcalalang]

that destination is perfect, the pool exists on the BIGIP already? all this does is add the pool member. i would expect the 400 if the pool isnt there

[jmcalalang]

when you ran newman-1 you should had got another output for the created objects, tcp, pool, vip ect, did those all pass?

[justingrantit]

Here's the pool...

root@(bigip-a)(cfg-sync In Sync)(Active)(/Common)(tmos)# list ltm pool
ltm pool module_3_pool {
    monitor module_3_http_monitor 
}

[justingrantit]

Yes. From memory everything passed. I don't have the screen output but here's what I can get from the JSON output file:

Nothing matches 4xx return code for build-1

[jmcalalang]

yeah you have the pool, thats whats important, can you try running newman-5 and then re-run 1?
5 will have some errors cause not everything has been created yet

5 is the cleanup preparing you for the next section

[justingrantit]

Same result :(

Build-5 cleans up
Build-1 works okay
Build-2 fails on new member
