Running docker compose up gives docker: 'compose' is not a docker command.
But docker-compose up works just fine.
What gives? I thought compose was supposed to be part of the docker cli now.
How can I run docker compose up and get the same/similar behavior as docker-compose up?
docker --version -> Docker version 20.10.10, build b485636f4b
docker-compose --version -> Docker Compose version 2.1.1

Docker (in the cli is docker) and Docker Compose (on the cli is docker-compose) are different things.
Docker is the engine where the containers run
Docker-compose is a manager or orchestrator for those containers
This means that you cannot do docker compose, the correct command is docker-compose
I think you're confused on the commands
the way to start a container using docker (only 1 container) is
docker run -ti ubuntu bash
On the other hand you can do the same with Docker compose but you need a docker-compose.yml file where all the configuration is written, then to start it is
docker-compose up
To sum up
Docker and docker compose are 2 different things. You can find more info here What is the difference between docker and docker-compose

It's because I had docker installed not through docker desktop.
I was using a minikube for my docker daemon, and the basic docker cli. But the basic cli (installed through brew install docker) doesn't have docker compose, that's part of docker desktop.
