[DOCKER] all-ruby is now available in ghcr.io/ruby/all-ruby

There is something called all-ruby that is useful for comparing the behavior of all versions of ruby. It is said that the image can now be pulled not only from docker hub but also from ghcr.io.

Execution example with an image from docker hub

Previously, the docker hub rubylang/all-ruby was used as the docker image, and it was used as follows. (The content of the execution example is a library that does not require require.)

$ docker run -it --rm rubylang/all-ruby env ALL_RUBY_SINCE=ruby-2.0 ./all-ruby -e 'p $".reject{|s|s.include?("/")}'
ruby-2.0.0-p0       ["enumerator.so"]
...
ruby-2.0.0-p648     ["enumerator.so"]
ruby-2.1.0-preview1 ["enumerator.so", "thread.rb"]
...
ruby-2.1.10         ["enumerator.so", "thread.rb"]
ruby-2.2.0-preview1 ["enumerator.so", "rational.so", "complex.so", "thread.rb"]
...
ruby-2.2.10         ["enumerator.so", "rational.so", "complex.so", "thread.rb"]
ruby-2.3.0-preview1 ["enumerator.so", "thread.rb", "rational.so", "complex.so"]
...
ruby-2.7.0-preview2 ["enumerator.so", "thread.rb", "rational.so", "complex.so"]
ruby-2.7.0-preview3 ["enumerator.so", "thread.rb", "rational.so", "complex.so", "ruby2_keywords.rb"]
...
ruby-3.0.0-preview1 ["enumerator.so", "thread.rb", "rational.so", "complex.so", "ruby2_keywords.rb"]

Execution example with image from ghcr.io

From this year, due to the stricter restrictions on docker hub, GitHub Container Registry (ghcr.io) will also be docker push, and ghcr.io/ruby/all-ruby You can now use it.

The above execution example was docker pull before the release of 3.0.0-preview1, so it is up to preview1, but the following execution example is the output when it is executed for the first time with 3.0.0-preview2 or later. is.

$ docker run -it --rm ghcr.io/ruby/all-ruby env ALL_RUBY_SINCE=ruby-2.0 ./all-ruby -e 'p $".reject{|s|s.include?("/")}'

Summary

Docker hub has also tightened the restrictions on docker pull, so it's useful to know that you can now also docker pull from ghcr.io.

Digression

As an aside, it seems that https://hub.docker.com/r/rubylang/ruby will also be available at ghcr.io/ruby/ruby. Please wait for the official announcement to actually use this.
