hello,
I'm testing docker image v0.9.0, it starts but I have this issue opening the rails console:

Thanks for the report @masterkain . It looks like we may need to upgrade the version of Ruby we use to build these docker images.

I don't understand the cause of this issue, but I have reproduced it. The fix from your stackoverflow of adding require 'uri' to the top of application.rb works, but I still don't understand it. I'm reluctant to make a change without understanding the issue. I'd love to hear an explanation if anyone can come up with one.

yeah that seems weird, however, if it may help at all, I've found the ruby 2.6.x series very stable across a large number of apps I have deployed, might be worth a try.

the only thing I recall when using the 2.6 image is that BUNDLE_PATH has some change: rubygems/bundler#7531 (comment)
