Hi Kyle,
The fundamental issue with not using Nginx is that all uploads/downloads
block the cloud controller instance. A long blocking request to the CC can
be a serious issue in any CF environment. As such, all instances of the CC
should be deployed with Nginx enabled and activated.
Best,
Zachary Auerbach, CF Runtime Team.

Hi Kyle,
This component is specifically designed to work with Nginx. Despite the
fact that you can successfully upload a buildpack by making a small change
with Nginx disabled there are many other areas where not having Nginx will
severely cripple the functionality of the Cloud Controller.
Why are you trying to deploy a CC without Nginx?

I know it's recommended, but uploading buildpacks seems to just be plain
broken without it (though I fixed it by changing 1 line of code in the
cloud controller). The question is, is this supposed to work or is this
something broken that I should make a PR for?

Hi Kyle,
We highly recommend using Nginx as a proxy for uploads and downloads
to/from the cloud controller. Without it all long-running data transfers to
the CC will block that instance of the cloud controller.
It's possible, but may have unintended and unsupported side-effects.

The thing is, I got it to work with use_nginx set to false just by
modifying one line of code in buildpack_bits_controller.rb. Couldn't the

For buildpacks, nginx handles most of the heavy lifting and then
passes modified parameters to the cc for processing. The upload processor
then uses the modified params to do the right thing...
Are you running a non-standard configuration that doesn't use nginx
to frontend cc?

After some more digging I found that it seems to be a problem in
https://github.com/cloudfoundry/cloud_controller_ng/blob/master/app/controllers/runtime/buildpack_bits_controller.rb#L21
.
The 'params' object here is being referenced incorrectly; it
contains a key called 'buildpack' that maps to an object which has a
:filename field which contains the correct buildpack filename, but the code
is trying to reference params['buildpack_name'], which doesn't exist, so it
throws an exception. Changing that above line to say uploaded_filename
= params['buildpack'][:filename] fixed the issue for me. Could this be
caused by my CLI and the cloud controller having out of sync versions? The
api version on the CC is 2.23.0, and tI've been using the 6.11 CLI.

If you want to create a gist with the log (with secrets
redacted) from running `cf` with CF_TRACE=true, we could certainly take a
look.

I'm having an issue where I can't upload any buildpack to
cloudfoundry; it says "The buildpack upload is invalid: a filename must be
specified" and the cf_trace confirms it's sending a null value for
filename. The thing is, I have specified a file name every time and get
this error. I've used a few different CLI versions and uploaded different
buildpacks as both zip files/directories, and nothing works. Is this a bug
in the CLI/cloud controller, or am I doing something wrong?
