Run landscape in ruby container, and get error.

Steps to duplicate the problem.

• run terraform plan |tee report to generate the output file

• run landscape in official ruby:alpine container

docker run -ti --rm -v $(pwd):/apps ruby:alpine sh
/ # gem install terraform_landscape

in container_definitions: part, there is empty.

If I directly run landscape < report on my mac, I can show the differences.

    container_definitions:   "Application": "abc",
                                    "Project": "abc"
                                  },
                                  "environment": [
                                    {
                             -        "name": "abc",
                             -        "value": "1000"
                             +        "name": "abc",
                             +        "value": 500"
                                    },

Not sure the error is related or not. I only see this error when run it in ruby container.

/usr/local/bundle/gems/commander-4.4.3/lib/commander/user_interaction.rb:334: warning: constant ::Data is deprecated

UPDATES:

I see the same error constant ::Data is deprecated, also can show the container_definitions differences in container ruby and ruby:slim. So it is only the problem in container ruby:alpine.

[sds]

Seems like this was introduced by Ruby 2.5.0:

$ ruby -e "puts RUBY_VERSION; ::Data"

Output on Ruby 2.4.2

2.4.2

Output on Ruby 2.5.0

2.5.0
-e:1: warning: constant ::Data is deprecated

There is an open issue on the commander gem.

@sds

Thanks.

Yes, I can confirm with container ruby:2.4-alpine, I don't see the error ::Data is deprecated, but the container_definitions is still empty.

Anyway, I use ruby:slim, works fine.
