Docker Permissions for Docker-Group pls

Hi,
I belong to docker-group but cannot do with anything on containers without sudo…is this expected?

truenas% getent group docker
docker:x:999:andur

truenas% docker images
permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Head “http://%2Fvar%2Frun%2Fdocker.sock/_ping”: dial unix /var/run/docker.sock: connect: permission denied

I have migrated TrueNAS from earlier Kubernetes to Docker and changed the ix-Applications Dataset to another drive…is this another problem with aclmode?
