Rails 5.2.1 and Docker?

Question

Ruby on Rails

Hello. Please tell me what could be the problem. I use Rails 5.2.1 Running Docker does not pick up changes in files, I have to restart docker. Although in version Rails 5.2.0 everything works fine. I did not make any settings, I created the project with the command 'rails new my_api --api'
There is a suspicion of the spring gem, I already tried it and removed it, but added it again, but it did not help.

gemfile

source 'https://rubygems.org'
git_source(:github) { |repo| "https://github.com/#{repo}.git" }
ruby '2.5.1'
gem 'rails', '~> 5.2.1'
gem 'pg'
gem 'bootsnap', '>= 1.1.0', require: false
# gem 'passenger', require: "phusion_passenger/rack_handler"
gem 'puma'
group :development, :test do
gem 'listen', '>= 3.0.5', '< 3.2'
gem 'byebug', platforms: [:mri, :mingw, :x64_mingw]
gem 'spring', ' >= 2.0.2'
end
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]
