Dotenv 3.1.5 breaks kamal deploy

[marciotoshio]

Maybe not a kamal problem but I'd like to let people aware, my latest deploys were broken and seems like the culprit is the new version of dotenv.

ERROR (Kamal::ConfigurationError): Exception while executing on host x.x.x.x: Secret 'DATABASE_URL' not found in .kamal/secrets.staging

I installed the previous gem version 3.1.4 before installing kamal in the CI

An issue is already open in dotenv repo bkeepers/dotenv#518

How did you fix, this completely broke my entire CI/CD workflow

[marciotoshio]

Install dotenv pinned to the previous version before Kamal

gem install dotenv -v '3.1.4' 
gem install kamal

@marciotoshio thanks for pointing this out! I have been debugging my Github Action the whole morning and finally came to the conclusion something in Kamal or it's dependencies was broken. Will lock dotenv for now.

The issue is because https://github.com/bkeepers/dotenv/blob/962641232d379472af77908dfed3f2f0a5c234dc/lib/dotenv/parser.rb#L56 is executed for environment variables that are already set. Seems like Kamal is using it incorrectly somehow as it expected that to be replaced.
