I am a beginner with Prefect, so I searched the internet and followed tutorials to see UI and server, during installation and configuration I ran the command "prefect server start" but I got a message of error, have you please on that? I have docker and docker compose install

Looks like your Docker doesnt have necessary permissions?

I got this message: " docker: Got permission denied while trying to connect to the Docker daemon socket at unix///var/run/docker.sock Post "http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/create": dial unix /var/run/docker.sock: connect: permission denied. See 'docker run --help' "

Uhh yeah it seems like you can’t even download/run the hello-world. I think you need to add appropriate permissions. Getting
docker run hello-world
working is a good test. Don’t use sudo cuz you will run into other issues

Ah ok sounds good! Just you let you know also that Prefect Cloud has 20k task runs for free every month, and is a lot easier to get started with

It’s a lot harder to start with local than to start with Cloud. Looks like you already have a process at port 8080 so the UI can’t start there
You can change the UI port in the CLI or turn off that process

I think I succeeded, just a question on the tutorials I see the frame in blue and I have it in gray is this normal or something is bugging me?

I think it’s really gray for server and blue on cloud
