tomcat部署web項目非常方便，把war包放到webapps目錄就可以了。本篇使用docker快速搭建一個tomcat環(huán)境
拉取官方最新版tomcat鏡像

—name yoyotomcat 容器重命名yoyotomcat
-p 8090:8080 容器的8080端口映射到主機的8090端口
-v ~/yoyo/tomcat/webapps/jenkins:/usr/local/tomcat/webapps/jenkins 容器的/usr/local/tomcat/webapps/jenkins 目錄掛載到本機~/yoyo/tomcat/webapps/jenkins
-d 掛后臺運行
docker run —name yoyotomcat -p 8090:8080 -v ~/yoyo/tomcat/webapps/jenkins:/usr/local/tomcat/webapps/jenkins -d tomcat
運行成功后 docker ps查看已運行容器
[root@yoyo jenkins]# docker run --name yoyotomcat -p 8090:8080 -v ~/yoyo/tomcat/webapps/jenkins:/usr/local/tomcat/webapps/jenkins -d tomcat
[root@yoyo jenkins]# docker ps

[root@yoyo jenkins]#如果用的是阿里云服務器，需在后臺開放8090端口，這樣在瀏覽器輸入http://主機ip:8090就能訪問到tomcat首頁了
tomcat環(huán)境已經(jīng)部署完成，接下來把war包放到tomcat下的webapps目錄就可以了，也就是/usr/local/tomcat/webapps。
前面啟動的時候，/usr/local/tomcat/webapps/jenkins目錄是掛載到本機的~/yoyo/tomcat/webapps/jenkins目錄。
只需下載jenkins.war放到jenkins目錄就可以了
cd 到~/yoyo/tomcat/webapps/jenkins/目錄
wget 下載jenkins.war
jar -xvf 解壓jenkins.war
[root@yoyo jenkins]# cd ~/yoyo/tomcat/webapps/jenkins/
[root@yoyo jenkins]# wget http://mirrors.jenkins-ci.org/war/latest/jenkins.war

[root@yoyo jenkins]#接著重啟tomcat容器就可以生效了
docker restart yoyotomcat
瀏覽器輸入訪問地址:http://主機ip:8090/jenkins就能訪問到主頁面了
上面是通過掛載tomcat下的webapps目錄，在本機上把war包放進去的方式。如果不掛載容器的目錄，試了下也是可以把war包放進去的
一個tomca鏡像可以啟動多個容器實例，可以再啟動一個yytomcat的容器實例,映射到主機的8091端口
[root@yoyo jenkins]# docker run --name yytomcat -p 8091:8080 -d tomcat

[root@yoyo jenkins]#啟動完成后在瀏覽器輸入http://主機ip:8091就可以訪問到tomcat首頁了，接著用docker cp 把本機的war包復制到y(tǒng)ytomcat容器里面
接著前面下載jenkins.war并解壓到~/yoyo/tomcat/webapps/jenkins/目錄步驟
docker cp 復制 jenkins整個目錄到 容器的/usr/local/tomcat/webapps/jenkins目錄
docker exec -it yytomcat /bin/bash 進入運行容器的交互環(huán)境
cd 到tomcat容器的webapps/jenkins目錄，查看到已經(jīng)復制成功
exit 退出容器
docker restart 重啟容器
[root@yoyo ~]# docker cp ~/yoyo/tomcat/webapps/jenkins/ yytomcat:/usr/local/tomcat/webapps/jenkins
[root@yoyo ~]# docker exec -it yytomcat /bin/bash
