Ubuntu 14.04

第一次安装Docker，运行hello-world 是可以的，

重启系统之后，运行hello-world 出现如下报错：

Cannot connect to the Docker daemon. Is the docker daemon running on this host?

多方查找，解决如下：

sudo su -                       //切换到root

service docker start      //启动docker service

docker images              //显示所有images

docker run hello-world  //重新运行

恩，是权限问题，当前用户没权限，root用户可以运行

Cannot connect to the Docker daemon. Is the docker daemon running on this host

查看docker version的时候出现Cannot connect to the Docker daemon. Is the docker daemon running on this host 原因:当前登陆的用户权限不够 两个解决方法: 1 使用sudo sudo docker version 2 添加当前用户到docker group sudo usermod -aG docker $USER 学习的时候最好是使用第二种,稍微方便一点,不用多敲sudo

docker: Error response from daemon: OCI runtime create failed 解决办法

错误原因 在新服务器上安装好docker后,发现无法运行,经常一顿搜索后,发现是docker安装的版本过高,最新版本docker-18.06 的核心好像没有经过充分的测试就发布了. 导致一运行,就提示: docker: Error response from daemon: OCI runtime create failed: container_linux.go:348: starting container process caused "process_linux.go:301: runn

Ubuntu-Docker［1］安装Docker，通过Docker部署net core代码，需要结合［.NET Core 18］发布、ASP.NET Core Docker部署

1)通过系统自带包安装 通过自带包安装,可能Docker版本较旧 $ sudo apt-get update Reading package lists... Done $ sudo apt-get install -y docker.io {{{-y表示同意.没有-y也可执行,系统会问是否安装,输入y回车即可 apt-get -y install这个指令则是跳过系统提示,直接安装.}}} Adding group `docker' (GID 121) ... Done. docker star

最近学习Docker，将docker所有命令实验了一番，特整理如下：

【亲测有效】Centos安装完成docker后启动docker报错docker: unrecognized service的两种解决方案

今天在学习Docker的时候 使用yum install docker安装完后启动不了,报错如下: [[email protected] ~]# service docker start docker: unrecognized service 一直停留在以上步骤,如果有遇到和我一样类似问题的小伙伴可以按照如下方法进行安装,即可安装成功~~ 方法一: 先移除docker [[email protected] ~]# yum remove docker 再移除docker-selinux(如果你之
