文件冲突

Transaction check error:

解决方法: 先安装lvm2

[root@localhost ~]# sudo yum install lvm2 -y
[root@localhost ~]# sudo yum install docker -y
[root@localhost ~]# docker -v
Docker version 1.10.3, build 20f81d

Docker daemon未运行

[root@localhost ~]# docker pull ubuntu
Using default tag: latest
Warning: failed to get default registry endpoint from daemon (Cannot connect to the Docker daemon. Is the docker daemon running on this host?). Using system default: https://index.docker.io/v1/
Cannot connect to the Docker daemon. Is the docker daemon running on this host?
解决方法: 重启docker服务

[root@localhost ~]# service docker restart
Redirecting to /bin/systemctl restart docker.service

Docker被墙

[root@localhost ~]# docker pull centos
Using default tag: latest
Pulling repository docker.io/library/centos
Error while pulling image: Get https://index.docker.io/v1/repositories/library/centos/images: dial tcp: lookup index.docker.io on 10.28.10.166:53: no such host

由于docker镜像站被墙,推荐使用灵雀云镜像
解决方法: pull的时候使用国内镜像地址
