Description of problem:

We are seeing this when deploying a Dockerfile-based project:

-----> Creating http nginx.conf -----> Running nginx-pre-reload remote: /tmp/bashenv.738885525: line 134: syntax error near unexpected token (' remote: /tmp/bashenv.738885525: line 134: eval "$1() { ’ remote: /home/dokku/.basher/bash: main: command not found

Output of the following commands

How was Dokku installed?:

How reproducible:

100%

Steps to Reproduce:

1. dokku apps:destroy foobar && dokku apps:create foobar
2. git push dokku release/example:master # dokku remote points to foobar

Actual Results:

Successfully built 2ec6f4f7f08e -----> Releasing foobar (dokku/foobar:latest)… -----> Deploying foobar (dokku/foobar:latest)… -----> Attempting to run scripts.dokku.predeploy from app.json (if defined) -----> No Procfile found in app image -----> DOKKU_SCALE file not found in app image.

Expected Results:

I imagine nginx-pre-reload should successfully complete.
