Change in containers created by docker compose

docker compose

# Using docker subcommand `compose` 

$ docker compose up

$ docker container inspect kafka -f '       Image: {{ .Image }}{{"\n"}}Config.Image: {{.Config.Image}}'
       Image: sha256:d694642b6bef4693082bd6192d923f37af9e27ef15beef9de7d93a51d1a5d74d

docker-compose

# Using standalone `docker-compose`

$ docker-compose up

$ docker container inspect kafka -f '       Image: {{ .Image }}{{"\n"}}Config.Image: {{.Config.Image}}'
       Image: sha256:d694642b6bef4693082bd6192d923f37af9e27ef15beef9de7d93a51d1a5d74d

Sooo, it's apparently in beta?
https://docs.docker.com/compose/cli-command/

Fine, let's install it using this totally non-sketchy script:
https://docs.docker.com/compose/cli-command/#install-on-linux

$ curl -L https://raw.githubusercontent.com/docker/compose-cli/main/scripts/install/install_linux.sh | sh

Okay, now let's see...

$ docker compose
docker: 'compose' is not a docker command.
See 'docker --help'

Okay, maybe it didn't update the PATH correctly, let's manually run the binary that the script downloads:

$ curl -s 'https://api.github.com/repos/docker/compose-cli/releases/latest' | grep "browser_download_url.*docker-linux-amd64" | cut -d : -f 2,3
"https://github.com/docker/compose-cli/releases/download/v1.0.17/docker-linux-amd64"

$ curl -OL https://github.com/docker/compose-cli/releases/download/v1.0.17/docker-linux-amd64
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed

$ ./docker-linux-amd64 compose
docker: 'compose' is not a docker command.
See 'docker --help'

(╯°Д°）╯ ︵🐋

Okay, finally got it working after finding the last paragraph in the docker/compose-cli README

So, the v1.* releases does not include docker compose. So... what are they? Go-versions of docker-compose? Nope, they are patched versions of the Docker CLI, adding another version field labeled Cloud integration...

$ ./docker-linux-amd64 version
Client: Docker Engine - Community
 Cloud integration: 1.0.17

But okay, downloading the latest pre-release v2.0.0-beta.6 and moving it into the cli-plugins folder:

$ curl -L -o ~/.docker/cli-plugins/docker-compose --create-dirs \
  'https://github.com/docker/compose-cli/releases/download/v2.0.0-beta.6/docker-compose-linux-amd64'

$ docker compose

Usage:  docker compose [OPTIONS] COMMAND
...

Finally!

$ docker compose up -d
[+] Running 1/1
 ⠿ Container dc-test_web_1  Started

$ docker ps

No image tag, only ID. Well, at least it's consistent...
