Jenkins的Docker容器添加dotnet-sdk和git

前言

　　此文章仅仅是自己想弄一套自己构建程序

第一步

　　　　当前是自己写Dockerfile了。docker的仓库里面虽然有Jenkins的镜像。但是那镜像里面没有我们.netcore的构建环境。所以了，我需要做一个自己的镜像

　　　　在https://hub.docker.com中找Jenkins的基础镜像。好像没几个版本直接用最新的版本。

　　　　然后开始编写Dockerfile

#此镜像从jenkin中构建，添加dotnetcore build环境和git
#VERSION 1
#Author: txb
#

#基础镜像
FROM jenkins


#使用root管理员
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.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

#https://dotnet.microsoft.com/download/linux-package-manager/debian9/sdk-current
#官方操作
RUN wget -qO- https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.asc.gpg \
&& mv microsoft.asc.gpg /etc/apt/trusted.gpg.d/ \
&& wget -q https://packages.microsoft.com/config/debian/9/prod.list \
&& mv prod.list /etc/apt/sources.list.d/microsoft-prod.list \
&& chown root:root /etc/apt/trusted.gpg.d/microsoft.asc.gpg \
&& chown root:root /etc/apt/sources.list.d/microsoft-prod.list

#更新源，安装dotnet-sdk
RUN apt-get update && apt-get install -y dotnet-sdk-2.2

　　没写完，先保存一下build一下看看会不会报错

#后面有个点.
docker build -t txb-jenkins .

　　执行完了，还真报了一个错

E: The method driver /usr/lib/apt/methods/https could not be found.
E: Failed to fetch https://packages.microsoft.com/debian/9/prod/dists/stretch/InRelease
E: Some index files failed to download. They have been ignored, or old ones used instead.
The command '/bin/sh -c apt-get update && apt-get install -y dotnet-sdk-2.2' returned a non-zero code: 100

　　看着像是应该缺少什么东西来访问https的地址，百度了一下，还是真是缺少 apt-transport-https，没有，那么我先装上呗，修改Dockerfile

　　在安装dotnet-sdk前面增加一句再重新build（最好不要这么去干，我试过了，总共下来的镜像有2G多。。等待时间有点久，有耐性就试试）

RUN apt-get install -y apt-transport-https #这个也是会报错的
RUN apt-get update && apt-get install -y apt-transport-https

　　然后就是有点漫长的等待。不着急

　　接下来，我们添加git进去，Debian嘛，安装套一样

开始构建容器

docker run -d -p 8000:8080 -v /home/jenkins_home:/var/jenkins_home --name csit-dotnet-jenkins dotnet-jenkins

docker run -d -p 4040:8080 -v /home/jenkins/jenkins_home:/var/jenkins_home -v /home/jenkins/jenkins_publish:/home/jenkins_publish --name csit-dotnet-jenkins --privileged=true dotnet-jenkins

docker run -d -p 4040:8080 -v /home/app/:/home/jenkins_publish --name csit-dotnet-jenkins --privileged=true dotnet-jenkins

说明：-d：后台运行

-p：端口映射8000：8080 宿主主机端口8000，容器端口8080

-v：映射目录主机目录/home/jenkins_home ,容器目录/var/jenkins_home

--name：创建出容器的名字

--privileged=true：应该跟权限有关，如果不带此参数的话，在启动容器的时候容器访问/home/jenkins_home会抛出一个permission deny问题

dotnet-jenkins：镜像名称

补充一个问题：

后续在使用容器运行web的时候，Jenkins里面也需要使用宿主主机的docker命令，我不可能再Jenkins容器里面再装一个docker把后面百度了一下好像在容器内部使用docker命令也是可行

贴出一个文章连接https://www.cnblogs.com/leolztang/p/6934694.html

按照作者的思路，我又从新编辑了一下我的Dockerfile

在创建容器的时候指定挂载一下docker目录

创建容器的命令如下：

docker run --name csit-dotnet-jenkins --privileged=true -d -p 4040:8080 -v /home/app:/home/jenkins_publish -v /var/run/docker.sock:/var/run/docker.sock -v $(which docker):/usr/bin/docker dotnet-jenkins

Jenkins的Docker容器添加dotnet-sdk和git
