In Diego (maybe DEA also) why is $HOME /home/vcap/app and not /home/vcap?

Thanks for doing that research Eric. So, it appears to be some requirement

for Heroku compatibility. So, I guess I have 2 issues I'd like to dig further on that might help other from repeating the issue I experienced above: 1. Should ssh home be /home/vcap/app also to match application running environment? 2. Why is Java's "user.home" system property "/home/vcap". I would think that java's user.home should always match the HOME environment variable. Mike On Mon, May 9, 2016 at 2:38 PM, Eric Malm <emalm(a)pivotal.io> wrote:

HOME is also `/home/vcap/app` on the DEAs, and Diego has replicated that execution contract for buildpack apps (the buildpack-app-lifecycle's launcher sets HOME to that value before exec'ing the start command). Spelunking through the DEA codebase, it seems to have been that way since buildpack support was introduced: https://github.com/cloudfoundry/dea_ng/commit/43ea42bcbff09175cafa65c2e84bd36fd505be07 is the earliest reference I could find to it. Since /home/vcap/app is also symlinked to /app, this may be to keep compatibility with Heroku conventions around the HOME env var. Someone who was around in March 2013 (or who knows Heroku better! :) ) might be able to answer that more definitively, though.

directory identified by the java system property "user.home" (which is /home/vcap) instead of the environment variable $HOME which is /var/vcap/app. This is especially confusing because SSH home is "/home/vcap". Anyone have any context into why $HOME for the app is /var/vcap/app and not /var/vcap? Thanks, Mike |
