Docker之jekins的安装

jekins官网地址：Jenkins Plugins  （https://plugins.jenkins.io/）

jekins 的docker 官方地址：https://hub.docker.com/r/jenkins/jenkins

jekins 的docker 允许命令文档地址： docker/README.md at master · jenkinsci/docker · GitHub

（https://github.com/jenkinsci/docker/blob/master/README.md）

docker 拉取jekins镜像：docker pull jenkins/jenkins    （直接拉取最新的，我是最新的jdk17）

wangqinmin@wangqinmindembp ~ % docker pull jenkins/jenkins

docker查看镜像：docker images

wangqinmin@wangqinmindembp ~ % docker images
REPOSITORY            TAG       IMAGE ID       CREATED         SIZE
jenkins/jenkins       latest    fea411dfc883   2 days ago      469MB

先创建jenkins的文件挂载目录，我创建的文件地址是：/Users/wangqinmin/docker/jenkins

wangqinmin@wangqinmindembp docker % pwd
/Users/wangqinmin/docker
wangqinmin@wangqinmindembp docker % mkdir jenkins
wangqinmin@wangqinmindembp docker % ls
jenkins	mysql
wangqinmin@wangqinmindembp docker % cd jenkins 
wangqinmin@wangqinmindembp jenkins % pwd
/Users/wangqinmin/docker/jenkins

docker运行命令，并启动：

docker run --name jenkins17 -d -v jenkins_home:/Users/wangqinmin/docker/jenkins -p 8080:8080 -p 50000:50000 --restart=on-failure jenkins/jenkins

解释：

docker run

 --name jenkins17  自定义启动名称

-d     后台运行容器

-v jenkins_home:/Users/wangqinmin/docker/jenkins    挂载文件到指定的目录

-p 8080:8080      指定访问端口号，前面的8080是访问的端口号可以改，后面的8080是内部的端口号不能改

-p 50000:50000

--restart=on-failure

jenkins/jenkins   这个是 docker images 命令获取到的 REPOSITORY 列下面的数据

访问地址： localhost:8080

查看docker运行 容器列表，看 jenkins  命令：docker ps -a 

wangqinmin@wangqinmindembp jenkins % docker ps -a                                                                                                                                    
CONTAINER ID   IMAGE                       COMMAND                  CREATED         STATUS                      PORTS                                                                                      NAMES
90fca6a924c5   jenkins/jenkins             "/usr/bin/tini -- /u…"   4 seconds ago   Up 3 seconds                0.0.0.0:8080->8080/tcp, :::8080->8080/tcp, 0.0.0.0:50000->50000/tcp, :::50000->50000/tcp   jenkins17

找密码：
查看jenkins 服务器后台： 

docker exec -it jenkins17 /bin/bash

找到密码文件： 

wangqinmin@wangqinmindembp jenkins % docker exec -it jenkins17 /bin/bash
jenkins@90fca6a924c5:/$ ls
Users  bin  boot  dev  etc  home  lib  lib64  media  mnt  opt  proc  root  run	sbin  srv  sys	tmp  usr  var
jenkins@90fca6a924c5:/$ cd /var/jenkins_home/secrets
jenkins@90fca6a924c5:~/secrets$ ls
initialAdminPassword  jenkins.model.Jenkins.crumbSalt  master.key

 查看密码：
 

jenkins@90fca6a924c5:~/secrets$ cat initialAdminPassword 
3a359747885f46c3ab68742a7334df02
jenkins@90fca6a924c5:~/secrets$ 

复制密码：3a359747885f46c3ab68742a7334df02

然后先安装一些推荐插件，后面再根据需要安装插件即可。

部分安装失败，先不管，后面再说，先点继续，去改密码

新建一个用户，点击 保存并完成，就好了

完成：
