Ruby 2.3.6

[EricRoos]

How can I get Ruby 2.3.6 installed?

I also have a rails app that requires Bundler 1.10.6 and this seems impossible after 2 days of struggling.

Any guidance?

Is there something wrong with 2.3.7 that makes it insufficient? 2.3.6 isn't supported (by Ruby upstream or by us), so using it isn't a real great plan.

Regardless, we don't delete old tags, so you should be able to pull ruby:2.3.6 and get the older version. To get older bundler, you'll probably have to explicitly remove the bundler included in the image (and/or convince gem install to force overwrite it).

Hard work requirement of 2.3.6. This is a non negotiable.

When I pulled in 2.3.6 ruby --version returned 2.3.7.

And the issue with bundler it seems that the bin file that gets generated keeps trying to call the 1.16.x version.

I can't reproduce the first issue:

$ docker pull ruby:2.3.6

However, it seems like your best bet from here would be to take our Dockerfile and modify it to suit your needs directly (since you have pretty specific requirements) -- that way you can explicitly install 2.3.6 and Bundler 1.10.6 right from the start.

Not sure what i was experiencing earlier. but this is right on. Thank you.

This has been my conclusion as well. Thank you for the prompt reply and help. I'll open another issue if I still have problems with bundler.
