[系统运维]如何把镜像上传到DockerHub

Docker 官方维护了一个Docker Hub公共仓库 ，其中已经包括了数量超过 15,000 的镜像。日常大部分需求都可以通过在 Docker Hub 中直接下载镜像来实现，但是有时需要根据自己的需要传自己制作的镜像上去，以供使用。

以下为如何把镜像上传到DockerHub操作过程：

1 DockerHub账号

1.1 注册账号

首先去https://hub.docker.com注册一个hub的帐号；通过执行 docker login 命令交互式的输入用户名及密码来完成在命令行界面登录 Docker Hub。

说明：hub.docker.com有时国内连的会比较慢。

1.2 docker login

[root@centos64-master ~]# docker login

Login with your Docker ID to push and pull images from Docker Hub. If you don't have a Docker ID, head over to https://hub.docker.com to create one.

Username: XXX

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-store

Login Succeeded

[root@centos64-master ~]#

1.3 docker logout

通过 docker logout 退出登录。

[root@centos64-master ~]# docker logout

Removing login credentials for https://index.docker.io/v1/

创建后在dockers服务器上使用docker login进行登陆，登陆后即可进行仓库的上传下载动作。

1.4 创建仓库Repositories

在hub.docker.com的Repositories进行Create Repository，例如：

https://hub.docker.com/repository/create?namespace=XXX

Create Repository创建完成

可以看到推送命令：docker push XXX/jmeter:tagname

2 制作docker image

2.1 制作镜像/build image

参考：https://www.cnblogs.com/majestyking/p/10745264.html

做一个简单的包含jdk、Jmeter的docker镜像，jmeter工具包需要自行下载：apache-jmeter-5.4.1.tgz。

##Dockerfile的内容：

FROM java:8

ENV http_proxy ""
ENV https_proxy ""

RUN mkdir /jmeterdocker
RUN mkdir -p /jmeterdocker/test
RUN mkdir -p /jmeterdocker/test/input/jmx
RUN mkdir -p /jmeterdocker/test/input/testdata
RUN mkdir -p /jmeterdocker/test/report/html
RUN mkdir -p /jmeterdocker/test/report/jtl
RUN mkdir -p /jmeterdocker/test/report/outputdata
RUN chmod -R 777 /jmeterdocker

ENV JMETER_VERSION=5.4.1
ENV JMETER_HOME=/jmeterdocker/apache-jmeter-${JMETER_VERSION}
ENV JMETER_PATH=${JMETER_HOME}/bin:${PATH}
ENV PATH=${JMETER_HOME}/bin:${PATH}

COPY apache-jmeter-5.4.1.tgz /jmeterdocker

RUN cd /jmeterdocker \
? ? && tar xvf apache-jmeter-5.4.1.tgz \
? ? && rm apache-jmeter-5.4.1.tgz

##制作镜像命令：

docker build -t jmeterdocker:5.4.1 .

##创建的过程操作：

[root@centos64-master jmeterDocker]# docker build -t jmeterdocker:5.4.1 .
...
apache-jmeter-5.4.1/docs/api/org/apache/log/package-frame.html
apache-jmeter-5.4.1/docs/api/org/apache/log/package-summary.html
apache-jmeter-5.4.1/docs/api/org/apache/log/package-tree.html

?---> 0f7b46e5322f
Successfully built 0f7b46e5322f
Successfully tagged a007zheng/jmeterdocker:5.4.1

##创建完成以后查询：

[root@centos64-master jmeterDocker]# docker images
REPOSITORY                                                        TAG        IMAGE ID       CREATED          SIZE
XXX/jmeterdocker                                            5.4.1      0f7b46e5322f   29 minutes ago   843MB

2.2 推送镜像/push image

将制作好的镜像 push 到docker hub中，?命令:docker push XXX/jmeterdocker:5.4.1??这个5.4.1其实是一个tag name 会在dcoker?hub的Tags那里显示。

至此镜像推送完成。

2.3 下载镜像/pull image

[root@centos64-master jmeterDocker]# docker login
Login with your Docker ID to push and pull images from Docker Hub. If you don't have a Docker ID, head over to https://hub.docker.com to create one.
Username: XXX
Password:

https://docs.docker.com/engine/reference/commandline/login/#credentials-store

Login Succeeded


[root@centos64-master jmeterDocker]# docker push a007zheng/jmeterdocker:5.4.1
