在hub.docker发布自己的image

---

前言：创建自己的docker image并上传到hub.docker仓库

⚠️先注册hub账户 https://hub.docker.com/
1.创建Dockerfile
2.构建Image
3.打标签Image
4.登录hub.docker
4.上传Image

1.创建Dockerfile

这里以swoole环境为例子，创建一个自己的docker开发环境

#  基础镜像
FROM php:7.1

# 作者信息
MAINTAINER degree757 

# 环境变量
ENV SWOOLE_VERSION 1.10.3

# Timezone
RUN /bin/cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \
    && echo 'Asia/Shanghai' > /etc/timezone

# 依赖
RUN apt-get update \
    && apt-get install -y \
        curl \
        wget \
        git \
        zip \
        libz-dev \
        libssl-dev \
        libnghttp2-dev \
        libpcre3-dev \
    && apt-get clean \
    && apt-get autoremove

# PDO extension
RUN docker-php-ext-install pdo_mysql

# Bcmath extension
RUN docker-php-ext-install bcmath

# Swoole extension
RUN wget https://github.com/swoole/swoole-src/archive/v${SWOOLE_VERSION}.tar.gz -O swoole.tar.gz \
    && mkdir -p swoole \
    && tar -xf swoole.tar.gz -C swoole --strip-components=1 \
    && rm swoole.tar.gz \
    && ( \
        cd swoole \
        && phpize \
        && ./configure --enable-mysqlnd --enable-openssl --enable-http2 \
        && make -j$(nproc) \
        && make install \
    ) \
    && rm -r swoole \
    && docker-php-ext-enable swoole

2.构建Image

在Dockerfile目录下，运行构建Image命令

➜  docker build -t swoole . 

3.打标签Image

docker image ls查看当前本地镜像

➜  docker image ls
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
swoole              1.10                dbee969e838c        2 hours ago         425MB
php                 7.1                 8bbf0726af2d        3 weeks ago         358MB   
➜  docker tag dbee969e838c degree757/swoole:1.10

给swoole镜像打个标签 docker tag dbee969e838c degree757/swoole:1.10

• degree757 是你们自己在hub.docker的ID
• swoole:1.10 镜像以及版本

⚠️dbee969e838c是你们自己的IMAGE ID

4.登录hub.docker

通过login命令登录

➜  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: degree757
Password: 
Login Succeeded

4.上传Image

推送本地镜像到hub.docker，至此完毕

➜  docker push degree757/swoole

总结

发布镜像成功，开启持续集成
