使用Docker部署Jenkins

安装Jenkins：
首先不直接从Docker Store上直接Pull Jenkins 的 Image 文件，因为待会需要进行dotnet core 的 Docker自动部署，需要对宿主机上的Docker进行直接操作，那么需要挂载 Docker 给 Jenkins Image，所以现在需要自己动手编写 Dockerfile 构建自定义的Jenkins。
1.新建Dockerfile
touch Dockerfile
vim Dockerfile
2.加入以下内容：
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 tencentyun 改为 aliyun
RUN echo '' > /etc/apt/sources.list.d/jessie-backports.list \
&& echo "deb http://mirrors.tencentyun.com/debian jessie main contrib non-free" > /etc/apt/sources.list \
&& echo "deb http://mirrors.tencentyun.com/debian jessie-updates main contrib non-free" >> /etc/apt/sources.list \
&& echo "deb http://mirrors.tencentyun.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
RUN curl -L https://github.com/docker/compose/releases/download/1.16.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
RUN chmod +x /usr/local/bin/docker-compose
3.构建image
docker build . -t auto-jenkins
[[email protected]_0_7_centos ~]# docker build . -t auto-jenkins
Sending build context to Docker daemon 596.5 kB

出现以上 Successfully 内容代表安装Jenkins成功
4.在启动Jenkins时，需要先创建一个Jenkins的配置目录，并且挂载到docker 里的Jenkins目录下
5.修改目录权限（很重要！）
6.运行 Jenkins
出现一串很长的字符串以后，我们的jenkins已经成功启动：
[[email protected]_0_7_centos ~]# mkdir -p /var/jenkins_home
[[email protected]_0_7_centos ~]# chown -R 1000 /var/jenkins_home/
[[email protected]_0_7_centos ~]# docker run --name jenkins -p 8080:8080 -p 50000:50000 \
> -v /var/run/docker.sock:/var/run/docker.sock \
> -v $(which docker):/bin/docker \
> -v /var/jenkins_home:/var/jenkins_home \
> -d auto-jenkins
d74d82661514205d6e1ac56574724277400a26a3095aca4497dad5bf8039816d
通过命令docker ps查看运行的镜像：
[[email protected]_0_7_centos ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
d74d82661514 auto-jenkins "/bin/tini -- /usr..." 13 seconds ago Up 11 seconds 0.0.0.0:8080->8080/tcp, 0.0.0.0:50000->50000/tcp jenkins
配置Jenkins
访问http://<你的ip>:8080访问Jenkins。
可以看到需要我们输入密码。
首选进入容器：
docker exec -it jenkins /bin/bash
然后查看密码：
[[email protected]_0_7_centos ~]# cat /var/jenkins_home/secrets/initialAdminPassword
22e09f367d314ba99838aa080162daba
复制输出的内容，粘贴到Administrator password，输入 exit 退出容器，此时进行下一步你会看到此界面，点击 Install suggested plugins
等待安装完毕：
如果有插件安装失败，不用紧张，安装结束之后会有"Retry”重试选项，点击重试即可。
根据表单填写信息之后就结束了！
进入主界面后如果看到右上角有错误的提示信息，那么请把你的Jenkins升级到最新版本，然后更新一下插件。
如果更新之后出现协议警告：
