Jenkins 部署Docker站点

部署

创建Docker镜像

创建Dockerfile文件

注意事项
* 用root用户替换默认的Jenkins用户
* 切换为国内源，加快构建速度
* 在镜像里面安装docker-compose
* curl 命令无法再Dockerfile文件里执行，需要在docker run的镜像里执行，这个后续看怎么解决

FROM jenkins
USER root
#清除了基础镜像设置的源，切换成腾讯云的jessie源
#使用非腾讯云环境的需要将 aliyun 改为 aliyun
RUN echo '' > /etc/apt/sources.list.d/jessie-backports.list \
  && echo "deb http://mirrors.aliyun.com/debian jessie main contrib non-free" > /etc/apt/sources.list \
  && echo "deb http://mirrors.aliyun.com/debian jessie-updates main contrib non-free" >> /etc/apt/sources.list \
  && echo "deb http://mirrors.aliyun.com/debian-security jessie/updates main contrib non-free" >> /etc/apt/sources.list
#更新源并安装缺少的包
RUN apt-get update && apt-get install -y libltdl7 && apt-get update
ARG dockerGid=999
RUN echo "docker:x:${dockerGid}:jenkins" >> /etc/group 
# 安装 docker-compose 因为等下构建环境的需要
curl -L "https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
RUN chmod +x /usr/local/bin/docker-compose
# 测试docker-compose安装是否成功
# docker-compose --version

生成镜像、安装镜像

# 构建
docker build  -t mkm-jenkins .
#创建容器
docker run --name jenkins -p 8085:8080 -p 50000:50000 \ 
-v /var/run/docker.sock:/var/run/docker.sock \
-v /usr/bin/docker:/usr/bin/docker \ 
-v /wdc/docker/jenkins/jenkins_home:/var/jenkins_home \
-d d1cf34ad7a7f

docker构建shell命令

down 命令详解
Usage: down [options]
Options:
    --rmi type          删除镜像，类型必须是:
                        'all': 删除compose文件中定义的所以镜像.
                        'local': 删除镜像名为空的镜像
--volumes       删除卷
                        attached to containers.
    --remove-orphans    Remove containers for services not defined in the
file
停止和删除容器、网络、卷、镜像，这些内容是通过docker-compose up命令创建的.  默认值删除 容器 网络，可以通过指定 rmi volumes参数删除镜像和卷
