docker镜像打包
前言
docker打包镜像
简单栗子
使用nginx打包一个静态页面的镜像
测试的代码地址[https://github.com/boilingfrog/daily-test/tree/master/docker-images/test]
1、制作dockerfile
FROM nginx
COPY test /usr/share/nginx/html
2、打包镜像
docker build -t test-static ./test
结果
$ docker build -t test-static ./test
Sending build context to Docker daemon 9.728kB
Step 1/2 : FROM nginx
---> 4bb46517cac3
Step 2/2 : COPY test /usr/share/nginx/html
---> fc981d4aa54c
Successfully built fc981d4aa54c
Successfully tagged test-static:latest
test-static表示打包成的镜像名，./test打包镜像代码地址
3、镜像打上tag
如果我要上传的地址是https://hub.docker.com/,把tag打成你在https://hub.docker.com/注册的用户名加镜像的命名就好了
docker tag test-static:latest liz2019/test-static
当然后面也是可以加上版本，如果不加就是默认的latest
docker tag test-static:latest liz2019/test-static:v1
如果希望上传到自己的搭建的仓库，那么只需加上自己的仓库地址就好了
docker tag test-static:latest hub.xxx.com/xxx/test-static:v1
4、上传到仓库
直接push刚打完tag的镜像就好了,上传到https://hub.docker.com/是需要登录的。
docker push liz2019/test-static
结果
$ docker push liz2019/test-static
The push refers to repository [docker.io/liz2019/test-static]

成功了
最后运行下docker run -p 8000:80 test-static
