push到Docker Hub

1.注册DockerHub账号

官方网站：https://www.docker.com/products/docker-hub

2.1 Dockerfile生成镜像

下面我以自己的Dockerfile文件来演示
1.这是我的目录结构

[root@localhost dockerfile]# tree
.
├── apache-tomcat-9.0.52.tar.gz
├── data
│   ├── logs
│   ├── test
│   │   └── index.jsp
│   └── web.xml
├── Dockerfile
├── jdk-8u291-linux-x64.tar.gz
└── readme.txt

2.Dockerfile文件内容

[root@localhost dockerfile]# vim Dockerfile FROM  centos
MAINTAINER  jing_lron<954213209@qq.com>COPY  readme.txt  /usrl/local/readme.txtADD jdk-8u291-linux-x64.tar.gz  /usr/local/
ADD apache-tomcat-9.0.52.tar.gz   /usr/local/RUN yum -y install vimENV MYPATH /usr/local
WORKDIR $MYPATHENV JAVA_HOME /usr/local/jdk1.8.0_291
ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
ENV CATALINA_HOME  /usr/local/apache-tomcat-9.0.52
ENV CATALINA_BASH  /usr/local/apache-tomcat-9.0.52
ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/lib:$CATALINA_HOME/binEXPOSE 8080CMD /usr/local/apache-tomcat-9.0.52/bin/startup.sh && tail -F /url/local/apache-tomcat-9.0.52/bin/logs/catalina.out

3. 运行Dockerfile文件生成镜像

[root@localhost dockerfile]# docker build -f Dockerfile(你的dockerfile名） -t diytomcat(要生成镜像的名） . （注意这里有个点）

[root@localhost dockerfile]# docker build -f Dockerfile  -t diytomcat .
Sending build context to Docker daemon  156.5MB

Successfully built 75d38df6f360
Successfully tagged diytomcat:latest

此时镜像文件已经生成

[root@localhost dockerfile]# docker images
REPOSITORY    TAG       IMAGE ID       CREATED        SIZE
diytomcat   latest    75d38df6f360   10 hours ago     585MB

4. 登陆DockerHub

[root@localhost dockerfile]# docker login -u <你的账户名>

[root@localhost dockerfile]# docker login -u  jing*****
Password:
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-storeLogin Succeeded

4. 打标签

为什么要打标签？
因为当许多人都上传同一个名字的镜像时会导致无法分辨那个镜像是谁上传的，所以要在镜像前面打上上传者账号名和在镜像后面加上版本号
这是未打标签的镜像

[root@localhost dockerfile]# docker images
REPOSITORY          TAG       IMAGE ID       CREATED        SIZE
diytomcat          latest    75d38df6f360   11 hours ago   585MB
.......

为jingcentos1.0打标签

[root@localhost dockerfile]# docker tag diytomcat:latest   jingziyang/diytomcat:v1

打完标签后

[root@localhost dockerfile]# docker images
REPOSITORY              TAG       IMAGE ID       CREATED        SIZE
jingziyang/diytomcat   v1        75d38df6f360   11 hours ago   585MB
......

5. 上传到DockerHub

[root@localhost dockerfile]# docker push jingziyang/diytomcat:v1
The push refers to repository [docker.io/jingziyang/jingcentos]
b7ade542ceba: Pushed
34891d097958: Pushed
2da4ae156620: Pushed
2653d992f4ef: Pushed
v1: digest: sha256:d92c37b17ecd0bf29e214c3ff83c83cde9525b74b2d152efacfcb540f3b37798 size: 5850

退出DockerHub账号

[root@localhost dockerfile]# docker logout
Removing login credentials for https://index.docker.io/v1/

push到阿里云镜像库

1. 创建阿里云账号

阿里云官网：https://www.aliyun.com/
1.创建账号进入容器镜像服务

2.咱们一般为个人实例

3.创建命名空间和仓库

2. 登陆阿里云账号

$ docker login --username=jzy_****(你的账号) registry.cn-hangzhou.aliyuncs.com

[root@localhost dockerfile]# docker login --username=jzy_**** registry.cn-hangzhou.aliyuncs.com
Password:
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-storeLogin Succeeded

3. 给镜像打标签

1.打标签，未打标签镜像

[root@localhost dockerfile]# docker images
REPOSITORY                     TAG       IMAGE ID       CREATED        SIZE
diycentos                      v1      75d38df6f360     11 hours ago      585MB
.........

将要上传的镜像打标签

[root@localhost dockerfile]# docker tag 75d38df6f360 registry.cn-hangzhou.aliyuncs.com/workspace_001/workspace:v2
..........
