基于上一章 基于Jenkins自动打包并部署Tomcat环境_学习新鲜事物的博客-CSDN博客
1、安装docker-ce
在tomcat上创建远程命令
[root@tomcat ~]# mkdir /data
在tomcat上构建 tomcat基础镜像。在构建基础镜像之前需要先安装 Docker 与 JDK。
[root@tomcat ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
[root@tomcat ~]# yum -y install yum-utils device-mapper-persistent-data lvm2
[root@tomcat ~]# yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
已加载插件：fastestmirror
adding repo from: http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
grabbing file http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo to /etc/yum.repos.d/docker-ce.repo
安装dockers启动并查看
[root@tomcat ~]# yum -y install docker-ce
[root@tomcat ~]# systemctl start docker
[root@tomcat ~]# systemctl enable docker
[root@tomcat ~]# docker version

2、阿里云镜像加速器
[root@tomcat ~]# cat << END > /etc/docker/daemon.json
> {
> "registry-mirrors":[ "https://nyakyfun.mirror.aliyuncs.com" ]
> }
> END
[root@tomcat ~]# systemctl daemon-reload
[root@tomcat ~]# systemctl restart docker
[root@tomcat ~]# cat centos-7-x86_64.tar.gz | docker import - centos:7
sha256:a94721bf20e6e706ea0ab02bb4283bcd992e760542620aa908143dcf52012e39
[root@tomcat ~]# docker images

3、构建tomcat 基础镜像
[root@tomcat ~]# mkdir docker-tomcat
[root@tomcat ~]# cd docker-tomcat/
[root@tomcat docker-tomcat]# ls
[root@tomcat docker-tomcat]# rz
[root@tomcat docker-tomcat]# ll

[root@tomcat docker-tomcat]# vim Dockerfile
[root@tomcat docker-tomcat]# cat Dockerfile

4、构建一个Maven项目
在以上配置完成后，回到 Jenkins 首页，选择“新建任务”，然后输入一个任务名称 “probe-docker”，并选择“Maven project”配置项，点击当前页面下方的“确定”按钮。
probe-docker
在点击“确定”按钮，选择“源码管理”并选中“Git”,设置“Repository URL”地址。
git@192.168.50.51:/home/git/probe.git
选择“Build”-> clean package -Dmaven.test.skip=true
在上一步后面选择“构建后操作”中的“Send build artfacts over SSH”选项并进行。
scp 192.168.50.53:/root/.jenkins/workspace/probe-docker/psi-probe-web/target/probe.war /data/
docker run -itd --name tomcat-test -p 8090:8080 -v /data:/usr/local/apache-tomcat-8.5.40/webapps tomcat:v1
以上全部配置完成后，点击保存即可。然后点击刚才创建的工程任务“probe-docker“->” Build new”直至任务构建完成。开始构建过程中可以点击进度条查看
可以看到此工程任务已构建成功，并且在构建后，创建用于docker项目的 Docker Web 环境命令也执行成功。

浏览器访问http://192.168.50.54:8090/probe/
登陆进容器
[root@tomcat docker-tomcat]# docker exec -it 0 /bin/bash
[root@0ed51e281414 /]# vim /usr/local/apache-tomcat-8.5.40/conf/tomcat-users.xml
44 <role rolename="manager-gui"/>
45 <role rolename="admin-gui"/>
46 <user username="tomcat" password="tomcat" roles="manager-gui,admin-gui"/>
47 </tomcat-users> 在这一行上面加三行
重载启动
[root@tomcat data]# systemctl daemon-reload
[root@tomcat docker-tomcat]# systemctl restart docker
会挂掉从新启动就好了
[root@tomcat docker-tomcat]# docker ps -a

用户 tomcat
密码 tomcat
看到这里就成功了
可能错误
把容器删除从新创建
