Hallo everyone! Im new in development and I trying to deploy my first app. For example, when I run "fly deploy", I have got an error: INFO Starting init (commit: 0b28cec)...

On my local machine all Users have Full control for this directory. What I doing wrong?

Inside your Dockerfile there should be a line that looks like:

    chown -R rails:rails db log storage tmp /data

If that line is not there, try:

bundle update dockerfile-rails
bin/rails generate dockerfile

Andriy · June 24, 2023, 11:53am

Thanks for your answer! I`ve done all you said and my Dockerfile has a line:

RUN useradd rails --create-home --shell /bin/bash &&
chown -R rails:rails db log storage tmp
USER rails:rails

Then run fly deploy again and have the same error(((

None of this makes any sense, but perhaps the following will give you something to look for. The rails code in question:

github.com

rails/rails/blob/e88857bbb9d4e1dd64555c34541301870de4a45b/railties/lib/rails/commands/server/server_command.rb#L69-L73C10


      
          def create_tmp_directories
            %w(cache pids sockets).each do |dir_to_make|
              FileUtils.mkdir_p(File.join(Rails.root, "tmp", dir_to_make))
            end
          end

Note that it tries to create three directories, and you are failing on the third one, so presumably it must have been able to create the first two. The error you are getting is a permission failure which doesn’t make sense as the dockerfile chown’s the parent directory.

If the tmp/sockets directory exists on your local machine, delete it. Your source is uploaded minus the files listed in .dockerignore, which should contain:

# Ignore all logfiles and tempfiles.
/log/*
/tmp/*
!/log/.keep
!/tmp/.keep

Hi, I deleted tmp/sockets directory but problem still exist.
When I run fly deploy
