I have Ubuntu 22.04,

I have Java Spring-boot project, I run Idea, then run docker-compose.yml and get this message:

Cannot connect to the docker daemon at unix:///var/run/docker.sock. Is the docker daemon running? (Details:[13] Permission denied)

What should I check?

You can take this perfect Tutorial: https://www.digitalocean.com/community/tutorials/how-to-install-and-use-docker-on-ubuntu-22-04

The important section for you is: Step 2 — Executing the Docker Command Without Sudo (Optional)

Your Problem is that you try to use docker without sudo. You have no permission for that.
