Error

Updating docker-sync from version 0.7.2 to 1.0.4 makes the docker-sync-stack start command to fail with the following error :

Downgrading docker-sync gem to version 1.0.3 workaround this issue.

your docker-sync.yml

version: "2"

options:
  # default: docker-compose.yml if you like, you can set a custom location (path) of your compose file like ~/app/compose.yml
  # HINT: you can also use this as an array to define several compose files to include. Order is important!
  compose-file-path: 'docker-compose.yml'

  # optional, default: docker-compose-dev.yml if you like, you can set a custom location (path) of your compose file. Do not set it, if you do not want to use it at all

  # if its there, it gets used, if you name it explicitly, it HAS to exist
  # HINT: you can also use this as an array to define several compose files to include. Order is important!
  compose-dev-file-path: 'docker-compose-dev.yml'

  # optional, activate this if you need to debug something, default is false
  # IMPORTANT: do not run stable with this, it creates a memory leak, turn off verbose when you are done testing
  verbose: false

  # optional, default auto, can be docker-sync, thor or auto and defines how the sync will be invoked on the cli. Mostly depending if your are using docker-sync solo, scaffolded or in development ( thor )
  cli_mode: 'auto'
  # optional, maximum number of attempts for unison waiting for the success exit status. The default is 5 attempts (1-second sleep for each attempt). Only used in unison.
  max_attempt: 5

    # optional, a list of excludes. These patterns will not be synced
    sync_excludes: ['.git', 'log', 'node_modules', 'public/packs', 'tmp']

    # use this to change the exclude syntax.
    # Path: you match the exact path ( nesting problem )
    # Name: If a file or a folder does match this string ( solves nesting problem )
    # Regex: Define a regular expression

The problem is append is not present in ruby 2.4 - it was introduced in ruby 2.5 (https://ruby-doc.org/core-2.4.0/Array.html / https://ruby-doc.org/core-2.5.0/Array.html ).

I think that was happening unintended, but i'am not really planning to downgrade the implementation - ruby 2.4 is EOL.
I would rather release 1.0.5 and upper the minimum ruby to 2.5 in this case.

I can see you are using RVM, so just install 2.5+ and you should be good to go already.

Cool, I will upgrade my Ruby, it's a very old version anyway.

Having an error about my Ruby version would have help, so yeah, please update the minimum Ruby version 👍

released 1.0.5 to fix this
