у вас локи поднять на k8s?

когда запускал: promtail | level=error ts=2022-05-10T11:37:50.533826714Z caller=refresh.go:98 component=docker_discovery discovery=docker msg="Unable to refresh target groups" err="error while listing containers: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?"

Ну что написано, то и проверяй. Докер запущен, сокет на месте, права у промтейла есть на скрейп?

уже решил но появился новый promtail | level=error caller=target_group.go:95 msg="added Docker target" containerID=blablalala
