运行bundle exec时，如何使bundler在“ ps aux”中显示完整命令？

Question

I have a couple of rake tasks that I need to run in background. I'm using rbenv to manage my ruby versions, supervisord to run the tasks, and bundle to make sure I use the correct gems versions. My supervisord config for each task looks like this:

[program:data-importer]
command=/home/ubuntu/.rbenv/bin/rbenv exec bundle exec rake import:data
environment=RAILS_ENV=production,PATH=/home/ubuntu/.rbenv/shims:%(ENV_PATH)s,PRODUCTION=true
directory=/home/ubuntu/app/current
user=ubuntu
stdout_logfile=/var/log/app/%(program_name)s-out.log
stderr_logfile=/var/log/app/%(program_name)s-err.log
autostart=true

I'm also using consul to monitor my infrastructure, and I'm using a consul check to make sure that these scripts are running. The check calls a very simple bash script, shown below:

#!/bin/bash

if ps -ef | grep [i]mport:data | grep -v running; then
  echo "data importer running"
  exit 0
else
  echo "data importer not running"
  exit 2
fi

These scripts were running just fine until a couple of days ago, when these checks started to fail. The problem is that when I run ps -ef , the process listed doesn't contain import:data anymore. It now shows this:

ubuntu 30450 ... /home/ubuntu/.rbenv/versions/2.3.1/bin/rake

Nothing really changed on the machine, only the Ruby version. We used 2.2.2, and we upgraded to 2.3.1 last Friday. That's why I think it's a bundler issue, as we installed a newer version after the ruby upgrade.

We didn't see the problem until Sunday, but it could be that we just didn't see it before.

Can anyone help me with this? I've been stuck for a while now :(

要在ps -ef中获得所需的输出，您必须在rake调用周围加上引号：

bundle exec 'rake import:data'
