Docker结合Jenkins

 [root@docker ~]# mkdir JenkinsDocker

[root@docker ~]#cd JenkinsDocker/

 

 

（yi）也是可以从官方搜索镜像

 [root@dockerJenkinsDocker]# docker search jenkins

（er）编写构建

解决问题：

#下面的wget是我后来更改的，起初用的是curl，总是无法下载gpg这个文件下来，还要研究解决，curl -o gpg这个有时候可以下载下来

#起初使用的apt-get openjdk-6-jdk，因为从网上拉取的jenkins是最新版，所以要更新支持java最新，用java6无法运行，apt-get openjdk-8-jdk也没有这个包，所以修改为使用压缩包形式安装java，注意ADD命令是不会重命名的

首先，他设置了Ubuntu环境，加入了需要的Docker APT仓库，并加入了对应的GPG key。之后更新了包列表，并安装了Docker和Jenkins所需的包，加入了一些Jenkins需要的包

 

创建了/opt/jenkins目录，并把最新稳定版本的Jenkins下载都这个目录。还需要一些Jenkins插件，给Jenkins提供额外的功能

 

使用ENV指令吧JENKINS_HOME和JENKINS_MIRROR环境变量设置为Jenkins的数据目录和镜像站点

 

指定了VOLUME 指令，VOLUME指令从容器运行的宿主机上挂载一个卷，在这里，为了“骗过”Docker，指定/var/lib/docker作为卷，这是因为/var/lib/docker 目录是Docker用来存贮其容器的目录。这个位置必须是真实的文件系统，而不能是像Docker镜像层那种挂载点。

 

使用VOLUME 指令该诉Docker进程，在容器运行内部使用宿主机的文件系统，而不能是像Docker镜像层那种挂载点。

 

那么，我们使用VOLUME指令告诉Docker进程，在容器运行内部使用宿主机的文件系统作为容器的存储，这样，容器内嵌Docker的/var/lib/docker目录将保存在宿主机系统的/var/lib/docker/volumes目录下的某个位置

 

公开jenkins的8080端口

 

#先把启动脚本下载下来

[root@dockerJenkinsDocker]# wget https://dockerbook.com/code/5/jenkins/dockerjenkins.sh

构建

[root@dockerJenkinsDocker]# docker build -t "ubuntu/jenkins:1" .

 

创建容器

 

[root@dockerJenkinsDocker]# docker run -p 8080:8080 -d --name "jenkins"--privileged ubuntu/jenkins:1
