Docker compose v2 compat?

[butsjoh]

After a docker update (i am on osx) it turned on Docker compose V2 by default (see https://docs.docker.com/compose/cli-command/). After turning it off stuff started working again. Any idea if this is in the pipeline of being supported?

What error did you get?

I seem to be having the same issue:

Actual behaviour

dip provision hangs. it gets as far as creating networks and volumes and just sits there until I ctrl+c

Expected behaviour

The command successfully builds the images ready to be run by other dip commands

Environment

• OS X 11.2.3
• Docker Desktop 3.5.2
• dip 6.1.0

Notes

Worked fine until I updated Docker Desktop - I don't know what the previous version was, but I tend to update when it tells me there's a new version - so pretty up-to-date

Disabling the Use Docker Compose V2 checkbox under Experimental Features in Docker Desktop resolved the issue for me.

I got the following error "Can't separate key from value". It indeed seems related to docker compose v2 (apache/airflow#16949)

Do you have the env file?

[butsjoh]

Yes we have but all of our defined env variables have a value defined. Not sure if this is a dip problem perse and it is more docker related. I am using the most recent dip version (7.1.4). Will check later today if it is indeed related to my setup.

This also breaks readline in the Rails console; with Use Docker Compose V2 enabled, dip rails c gives a console where cursor keys just insert their escape sequences rather than moving the cursor, and Emacs keys like ⌃A do likewise. Disabling the setting in Docker Desktop restores the expected behaviour.

According to the link given above (https://docs.docker.com/compose/cli-command/) docker-compose is turning into docker subcommand -> docker compose
Hence the error:

Traceback (most recent call last):
        ...
         3: from /home/user/.rvm/gems/ruby-2.7.3/gems/dip-7.1.4/lib/dip/command.rb:30:in `exec_program'
         2: from /home/user/.rvm/gems/ruby-2.7.3/gems/dip-7.1.4/lib/dip/command.rb:48:in `run'
         1: from /home/user/.rvm/gems/ruby-2.7.3/gems/dip-7.1.4/lib/dip/command.rb:16:in `call'
/home/user/.rvm/gems/ruby-2.7.3/gems/dip-7.1.4/lib/dip/command.rb:16:in `exec': No such file or directory - docker-compose (Errno::ENOENT)

I changed docker-compose to docker compose in compose.rb:26 and the commands i ran through dip were successful.
So I believe to solve the issue and to maintain compatibility, the compose version should be defined as an option in dip.yml if it is possible.
Any thoughts?

Very good! I'll prepare DIP to the latest Compose command next week.
