Rails way to let router to handle all exception

What people tend to do is to handle exception in controller with rescue_from, well it is totally fine. However there is also a different way by delegating the handling to router.

Configure the app to handle exception with Router

# config/application.rb

config.exceptions_app = self.routes

How to get the log of varnish that runs under docker?

Well, you see varnishd does not output any log to STDOUT at all if run on foreground. In order to do so, Varnish provides different daemons for the job, that is varnishlog and its NCSA-format variant varnishncsa. Those logger daemon would pipe all outputs that varnish stores in memory fragments to a file, either /var/log/varnish/varnish.log or /var/log/varnish/varnishncsa.log respectively. Please remember that these log file can be re-configured. This tutorial is for the Varnish that is packaged for Ubuntu Trusty, in which default options of daemon are stored under /etc/default. You can peek into it to see what's the default for varnishlog or varnishncsa

In this quick tutorial, I am going to use varnishncsa instead. In your Dockerfile, you start varnishd first then varnishncsa and run tail -f /var/log/varnish/varnishncsa.log, I created a script:

You can’t perform that action at this time.
