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

Question

I'm trying to run all services from docker-compose.yaml in IntelliJ IDEA, but I get the message inside of the services panel that says

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

and the service is running

$ service docker status

● docker.service - Docker Application Container Engine

              └─2968617 /usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock

and running it from terminal doesn't work as well

$ docker compose -f docker-compose.yaml up -d

permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: 
Get "http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/json?all=1&filters=%7B%22label%22%3A%7B%22com.docker.compose.config-hash%22%3Atrue%2C%22com.docker.compose.project%3Dmongodb%22%3Atrue%7D%7D":

And after installing docker-compose and using that I get the following error:

$ docker-compose -f docker-compose.yaml up -d

I suggest you to follow the Offical linux post installation guide:

sudo groupadd docker
sudo usermod -aG docker $USER

Then log out and log back in so that your group membership is re-evaluated.

PS: if you don't do that, you can use docker only as root.
