linux – Docker命令无法连接到Docker守护程序

本站教程收集整理的这篇文章主要介绍了linux – Docker命令无法连接到Docker守护程序，本站教程本站觉得挺不错的，现在分享给大家，也给大家做个参考。

我想转移到Docker,所以我刚刚开始搞乱它.我在VirtualBox Ubuntu 15.10(Wily Werewolf)安装上安装了Docker,然后在suggested here我试着运行一个基本的nginx Docker镜像：

@H_404_5@$docker run --name myNginx1 -P -d Nginx
CAnnot connect to the Docker daemon. Is the docker daemon running on this host?

所以我检查了Docker是否正在运行：

@H_404_5@$sudo service docker status
● docker.service - Docker Application Container ENGIne
   Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)
   Active: active (running) since vr 2015-11-06 08:41:48 CET; 15min ago
     Docs: https://docs.docker.com
 Main PID: 7542 (docker)
   CGroup: /system.slice/docker.service
           └─7542 /usr/bin/docker daemon -H fd://

这表明Docker守护程序实际上已经在运行,但是为了确保我只是手动启动了Docker守护程序：

@H_404_5@$sudo docker daemon
INFO[0000] API listen on /var/run/docker.sock           
INFO[0000] [graphdriver] using prior storage driver "aufs" 
INFO[0000] Firewalld running: false                     
INFO[0000] Default bridge (docker0) is assigned with an IP address XXX.XX.X.X/XX. Daemon option --bip can be used to set a preferred IP address 
WARN[0000] Your kernel does not support swap memory limit. 
INFO[0000] Loading containers: start.                   

INFO[0000] Loading containers: done.                    
INFO[0000] Daemon has completed initialization          
INFO[0000] Docker daemon                                 commit=76d6bc9 execdriver=native-0.2 graphdriver=aufs version=1.9.0

然后我尝试再次运行图像,但结果相同：

@H_404_5@$docker run --name myNginx1 -P -d Nginx
CAnnot connect to the Docker daemon. Is the docker daemon running on this host?

我试过sudo’ing命令,但无济于事.我在这做错了什么？

解决方法:

您需要将当前用户添加到docker组,如下所示：

@H_404_5@sudo usermod -aG docker $(whoami)

注销&再次登录系统或重新启动系统.
通过docker版本测试
