1 - 官网信息
- 操作步骤：https://jenkins.io/zh/doc/book/installing/#docker
- Docker映像地址：https://hub.docker.com/r/jenkins/jenkins
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。

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

3.1 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

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

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

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。
