Jenkins - 以Docker方式启动Jenkins

1 - 官网信息

官网建议

  • 建议使用的Docker映像是jenkinsci/blueocean image(来自 the Docker Hub repository)
  • jenkinsci/blueocean：https://hub.docker.com/r/jenkinsci/blueocean/
  • 该镜像包含当前的长期支持 (LTS) 的Jenkins版本 （可以投入使用） ，捆绑了所有Blue Ocean插件和功能。这意味着你不需要单独安装Blue Ocean插件。

2 - 在64位的CentOS7.5中安装Docker

[root@test102 ~]# cat /etc/system-release
CentOS Linux release 7.5.1804 (Core) 
[root@test102 ~]# 
[root@test102 ~]# uname -a
Linux test102 3.10.0-957.el7.x86_64 #1 SMP Thu Nov 8 23:39:32 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
[root@test102 ~]#

2.1 准备工作

sudo yum remove docker docker-common docker-selinux docker-engine  # 卸载旧版本的Docker 
sudo yum install -y yum-utils device-mapper-persistent-data lvm2  # 安装必要的包
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo  # 设置稳定的仓库
sudo yum makecache fast  # 更新yum安装包索引

2.2 安装Docker CE

[root@test102 ~]# yum -y install docker-ce

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

3 - 在Docker中下载并运行Jenkins

3.1 命令解释

docker run \
  -u root \
  --rm \  # 关闭时自动删此容器
  -d \  # 在后台运行容器（即“分离”模式）并输出容器ID，否则在终端窗口中输出正在运行的此容器的Docker日志
  -p 8080:8080 \  # 映射主机端口（第一个数字8080）和容器端口（后一个数字8080），用于HTTP访问
  -p 50000:50000 \  # 映射主机端口（第一个数字50000）和容器端口（后一个数字50000），用于连接Agent
  -v jenkins-data:/var/jenkins_home \  # 将Jenkins的Home目录映射到本地
  -v /var/run/docker.sock:/var/run/docker.sock \  # 允许容器与Docker守护进程通信
  jenkinsci/blueocean

官方解释

3.2 实例日志

docker run \
   --name myjenkins \
   -u root \
   --rm \
   -p 8080:8080 \
   -p 50000:50000 \
   -v /tmp/jenkins-data:/var/jenkins_home \
   -v /var/run/docker.sock:/var/run/docker.sock \
   jenkinsci/blueocean

注意：

  • 这里未使用"-d"参数（“分离”模式），在终端窗口中输出正在运行容器的日志
  • 使用了“--rm”参数，容器关闭时自动删除此容器
[root@test102 ~]# docker run \
>   --name myjenkins \
>   -u root \
>   --rm \
>   -p 8080:8080 \
>   -p 50000:50000 \
>   -v /tmp/jenkins-data:/var/jenkins_home \

启动日志的“Jenkins is fully up and running”信息表明Jenkins启动成功。
在浏览器中，打开“http://192.168.16.102:8080”，可以看到Jenkins初始界面，根据提示逐步操作即可。

启动容器时对容器做了存储卷的映射，因此容器中“/var/jenkins_home/secrets/initialAdminPassword”文件，对应在主机中的位置为：/tmp/jenkins-data/secrets/initialAdminPassword

4.3 访问容器

通过docker exec命令

[root@test102 ~]# docker exec -it myjenkins bash
bash-4.4# 
bash-4.4# ps 
PID   USER     TIME  COMMAND
    1 root      0:00 /sbin/tini -- /usr/local/bin/jenkins.sh
    6 root      1:43 java -Duser.home=/var/jenkins_home -Djenkins.model.Jenkins.slaveAgentPort=50000 -jar /usr/sh
 1362 root      0:00 bash
 1371 root      0:00 ps
bash-4.4# uname -a
Linux 78036934ad20 3.10.0-957.el7.x86_64 #1 SMP Thu Nov 8 23:39:32 UTC 2018 x86_64 GNU/Linux
bash-4.4# 
bash-4.4# exit
exit
[root@test102 ~]#

4.4 访问Jenkins控制台日志

如果没有指定分离模式选项 -d 来执行docker run 命令， 那么将不在终端窗口中输出正在运行容器的日志
可以通过docker logs命令来访问

[root@test102 ~]# docker logs myjenkins
Running from: /usr/share/jenkins/jenkins.war
webroot: EnvVars.masterEnvVars.get("JENKINS_HOME")
2019-12-03 08:00:17.523+0000 [id=1]	INFO	org.eclipse.jetty.util.log.Log#initialized: Logging initialized @535ms to org.eclipse.jetty.util.log.JavaUtilLog

4.5 访问Jenkins主目录

如果在执行docker run命令时，指定了-v参数，那么Jenkins主目录（/var/jenkins_home）将映射到本地主机上的指定目录。
可以通过在本地主机直接访问此目录的内容。
例如，容器中/var/jenkins_home/secrets/initialAdminPassword文件对应的是在主机中的/tmp/jenkins-data/secrets/initialAdminPassword文件。
