Note how there is no Nginx layer exported.

If I downgrade to Nginx 0.0.195, it works fine.

Now an Nginx layer is exported.

This doesn't seem to be an issue when just using the Nginx buildpack by itself. I can use 0.0.196 and it works fine. It seems to be just in conjunction with Staticfile. Interestingly, when I run the integration tests for staticfile this doesn't happen either. The integration tests run fine and don't reproduce this problem.

I didn't look into it more, but this change seems like it could be what's causing the change in behavior: paketo-buildpacks/nginx@3648f33.

Thanks for reporting. This happened because we fixed a bug in nginx and staticfile, but hadn't released a version of staticfile. Should be fixed with gcr.io/paketo-community/staticfile:0.0.13 that I just released.

@arjun024 Thanks, the container can be started successfully. But the readme.md does not contain a container start command, in fact, a port arguments needs to be added. --env PORT=XX
