无法连接到位于unix:/var/run/docker.sock 的Docker 守护进程。 docker 守护进程是否正在运行？ （详细信息：IntelliJ 中的[13] 权限被拒绝

Question

我尝试在 IntelliJ IDEA 中运行

docker-compose.yaml

中的所有服务，但我在服务面板中收到一条消息：

无法连接到位于 unix:///var/run/docker.sock 的 Docker 守护进程。 docker 守护进程是否正在运行？ （详情：[13] 权限被拒绝）

服务正在运行

$ service docker status

并且从终端运行它也不起作用

$ 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:

安装

docker-compose

并使用它后，出现以下错误：

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

我建议你遵循官方linux安装后指南:

sudo groupadd docker
sudo usermod -aG docker $USER

然后注销并重新登录，以便重新评估您的群组成员身份。
