前言#

目前环境为centos7 64位

1
[root@diudiu ~]# cat /proc/version
2
Linux version 3.10.0-514.26.2.el7.x86_64 (builder@kbuilder.dev.centos.org) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-11) (GCC) ) #1 SMP Tue Jul 4 15:04:05 UTC 2017

Docker版本为主要参考W3C的相关课程 w3cschool

Docker 的使用#

Docker容器的使用#

暂时没看明白

Docker镜像使用#

列出镜像表

1
[root@diudiu ~]# docker images
2
REPOSITORY（镜像仓库源）  TAG（镜像标签）IMAGE ID（镜像ID）   CREATED（镜像创建时间） SIZE（大小）
3
docker.io/ubuntu        18.04               ccc6e87d482b        12 days ago         64.2 MB
4
docker.io/hello-world   latest              fce289e99eb9        13 months ago       1.84 kB

同一仓库源可以有多个 TAG，代表这个仓库源的不同个版本 REPOSTITORY 来定义不同的镜像,如ubuntu:18.04

获取镜像

docker pull ubuntu:18.04

-搜索镜像

1
docker search mysql

创建镜像资料不详，后续再补充
镜像更新

可以查看到副本 diudiu/ubuntu

构建镜像创建Dockerfile文件，具体介绍可参考这篇文章

[root@diudiu ~]# vim Dockerfile [root@diudiu ~]# cat Dockerfile FROM centos:6.7 MAINTAINER Fisher “fisher@sudops.com”

RUN /bin/echo ‘root:123456’ |chpasswd RUN useradd youj RUN /bin/echo ‘youj:123456’ |chpasswd RUN /bin/echo -e “LANG=“en_US.UTF-8"" > /etc/default/local EXPOSE 22 EXPOSE 80 CMD /usr/sbin/sshd -D

docker bulid -t 自定义镜像名目录可以使用绝对目录

1
[root@diudiu ~]# docker build -t diudiu/centos:6.7 /root/
2
LANG="en_US.UTF-8"
3
The command '/bin/sh -c /bin/echo -e "LANG=\"en_US.UTF-8\"" &gt; /etc/default/local' returned a non-zero code: 127
