基于Jenkins自动打包并部署docker环境

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

REPOSITORY TAG IMAGE ID CREATED SIZE

centos 7 a94721bf20e6 3 seconds ago 589MB

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。

root@tomcat data# ll

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

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

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
