Failed to execute script docker-compose while setting up Apache Airflow - docker

Question

I'm using Docker Compose to set up Apache Airflow and right when I use
docker-compose up airflow-init
I get this error:

[81] Failed to execute script docker-compose
This is the yaml file I'm using: https://airflow.apache.org/docs/apache-airflow/stable/docker-compose.yaml
And this was the tutorial I was following: https://www.youtube.com/watch?v=aTaytcxy2Ck&t=398s

Maybe you have docker installed but it is not running or your user is not configured to access it.
This is the same error as described here:
https://github.com/docker/compose/issues/7896
You can double-check it by running docker ps. If it shows no processes (but it does not errors out) then your docker is running and is properly configured.
Another thing to check if is your user is properly configured to access docker. On Linux you should make sure your user is added to docker group. See https://docs.docker.com/engine/install/linux-postinstall/
