Hi @chandan988, which command exactly is throwing the error for you? Would that be one starting with docker compose? This will most likely fail for you because you are using an older version of docker compose. You should probably upgrade as suggested on their website: Install the Compose plugin | Docker Documentation

Alternatively, you can replace docker compose (with a whitespace) with docker-compose (with a dash) to use your currently installed version of compose.

I also noticed we still mention installation instructions for the older version on our docs page, I’ve raised a PR to get this changed. I am very sorry for the confusion here.
