Docker实战十之上传镜像到阿里云库


阿里云镜像加速配置

#阿里云官网
https://www.aliyun.com/

操作步骤：

  • 注册一个属于自己的阿里云账户(可复用淘宝账号)
  • 获得加速器地址链接
  • 登陆阿里云开发者平台
  • 选择容器镜像服务

使用docker info 查看 加速器配置

什么是镜像？

镜像是一种轻量级、可执行的独立软件包，它包含运行某个软件所需的所有内容，我们把应用程序和配置依赖打包好形成一个可交付的运行环境(包括代码、运行时需要的库、环境变量和配置文件等)，这个打包好的运行环境就是image镜像文件。

镜像commit操作

ubuntu安装vim

# 1 运行 ubuntu
docker run -it ubuntu /bin/bash
# 2 更新软件包
apt-get update
# 3 安装vim
apt-get -y install vim

本地镜像发布到阿里云流程

1、登录阿里云Docker Registry

$ docker login --username=aliyun**** registry.cn-hangzhou.aliyuncs.com

用于登录的用户名为阿里云账号全名，密码为开通服务时设置的密码。

您可以在访问凭证页面修改凭证密码。

2、使用docker images 查看本地镜像

a123456@luludeMacBook-Pro-2 ~ % docker images
REPOSITORY                 TAG       IMAGE ID       CREATED         SIZE
myubuntu                   1.0       cedf9b6574ab   5 minutes ago   77.9MB
ubuntu                     latest    ca2b0f26964c   3 weeks ago     77.9MB
redis                      latest    170a1e90f843   2 months ago    138MB
redis                      5.0       99ee9af2b6b1   16 months ago   110MB

3、将镜像推送到Registry

a123456@luludeMacBook-Pro-2 ~ % docker tag cedf9b6574ab registry.cn-hangzhou.aliyuncs.com/yangyanping0615/myubuntu:1.0         
a123456@luludeMacBook-Pro-2 ~ % docker push registry.cn-hangzhou.aliyuncs.com/yangyanping0615/myubuntu:1.0
