1. 下载Image

[root@server /]# docker pull jenkins/jenkins

Status: Downloaded newer image for jenkins/jenkins:latest
docker.io/jenkins/jenkins:latest

2. 创建docker的文件影射卷，用户数据存储

[root@server tmp]# docker volume create jenkins_test
[root@server tmp]# docker volume inspect jenkins_test
[
    {
        "CreatedAt": "2020-07-18T10:49:17+08:00",
        "Driver": "local",
        "Labels": {},
        "Mountpoint": "/var/lib/docker/volumes/jenkins_test/_data",
        "Name": "jenkins_test",
        "Options": {},
        "Scope": "local"
    }
]
[root@server tmp]# 

3.创建container

[root@server /]# docker run --name=jenkins -d -p 8080:8080 -p 50000:50000 -v jenkins_test:/var/jenkins_home jenkins/jenkins
c7fb87aec99402febd95edddda5cf1dc7ad15437f674bf71a09692d93369ccb9
[root@server /]# 
[root@server /]# docker ps
CONTAINER ID   IMAGE             COMMAND                  CREATED         STATUS         PORTS                                              NAMES
c7fb87aec994   jenkins/jenkins   "/sbin/tini -- /usr/…"   9 minutes ago   Up 9 minutes   0.0.0.0:8080->8080/tcp, 0.0.0.0:50000->50000/tcp   jenkins

浏览器输入电脑IP地址+端口号：http://192.168.2.188:8080/

查看密码有两种方法：

#方法1：cat
docker exec jenkins cat /var/jenkins_home/secrets/initialAdminPassword

#方法2: 将文件从容器复制到服务器再查看
[root@localhost jenkins_home]# docker  cp jenkins:/jenkins_test/secrets/initialAdminPassword secrets/initialAdminPassword 
invalid output path: directory "/var/jenkins_home/secrets" does not exist

后改为如下命令成功，应该是权限的问题
[root@localhost jenkins_home]# docker cp jenkins:/var/jenkins_home/secrets secrets/
