    Thank you, man! Nice perfect demo! 👏 Also, yes, there might be labels if volumes were created on-demand when using Docker Compose. I simulate that behavior and add labels by myself on the creation of the volume. `docker volume create --label com.docker.compose.project=demodb1 --label com.docker.compose.version=2.27.1 --label com.docker.compose.volume=db_data demodb_copy`

    8:13 at this point the docker container is run with entrypoint and cmd arguments in the dockerfile. 8:20 at this point the docker container is run with cmd replaced with the command line argument, which is whoiam.

    • @ManuelCastellin
      @ManuelCastellin 9 หลายเดือนก่อน

      Hi @atexnik, thank you for your feedback. Indeed you’re right there’s the implicit entrypoint defined in the Dockerfile that will always execute unless otherwise specified. I’ll keep this in mind and be more explicit about it next time 🙏

      Hello Andres, I think indeed you can use socks5 proxies with Docker desktop. I have never done it myself, but you should be able to specify it using the *socks5h://* prefix

    • @ManuelCastellin
      @ManuelCastellin 8 หลายเดือนก่อน

      @@andres0546231 I've been reading about this issue and it is, indeed, not supported at the moment. I can offer two solutions: 1. Use an HTTP 2 Socks proxy like pproxy pypi.org/project/pproxy/ to spawn a local HTTP proxy that will then fulfill the connection by proxying once more to the configured socks5. 2. There should be a flag in the Docker Desktop "Edge" version to enable socks proxy support. This feature is still an MVP so I would not pick this if you need something stable Hope this helps

    If you create a volume with docker-compose, it will set metadata (labels) for the named volume(s). You should also set these labels on the copied volume to be able to use it with a duplicated docker-compose environment.
