运行容器

[root@zengchen ~]# docker run -d -p 8090:8080 --name tomcat -v                               /home/tomcat/test:/usr/local/tomcat/webapps/test tomcat:9.0
920314ff05613f32ccd8167b4aedcc867a0ead219371ec04f708784c51b3f036

可以首先进入容器 docker exec -it 62d770e36ad9a5 /bin/bash

找到tomcat的根目录，你会发现webapps下面什么东西都没有，这时候就要执行一条命令：cp -r webapps.dist/* webapps/

1
2
root@62d770e36ad9:/usr/local/tomcat/webapps# ls
ROOT  docs  examples  host-manager  manager

然后东西就全部进来了。

这个时候就可以curl localhost:8090

[root@zengchen ~]# curl localhost:8090
<!doctype html><html lang="en"><head><title>HTTP Status 404 – Not Found</title><style type="text/css">body {font-family:Tahoma,Arial,sans-serif;} h1, h2, h3, b {color:white;background-color:#525D76;} h1 {font-size:22px;} h2 {font-size:16px;} h3 {font-size:14px;} p {font-size:12px;} a {color:black;} .line {height:1px;background-color:#525D76;border:none;}</style></head><body><h1>HTTP Status 404 – Not Found</h1><hr class="line" /><p><b>Type</b> Status Report</p><p><b>Description</b> The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.</p><hr class="line" /><h3>Apache Tomcat/9.0.55</h3></body></html>

COPY README.txt /usr/local/README.txt

ADD apache-tomcat-9.0.55.tar.gz /usr/local

RUN yum -y install vim

EXPOSE 8080

CMD /usr/local/apache-tomcat-9.0.55/bin/startup.sh && tail -F /usr/local/apache-tomcat-9.0.55/bin/logs/catalina.out

这里的tomcat和jdk就需要自己去下载了。

创建镜像

1
docker build -t zengchen233/dittomcat:1.0 .

运行镜像

1
docker run -d -p 8090:8080 --name diytomcat -v /home/tomcat/webapps/自己项目的路径:/usr/local/apache-tomcat-9.0.55/webapps/自己项目的路径 -v /home/tomcat/webapps/tomcatlogs/:/usr/local/apache-tomcat-9.0.55/logs diytomcat

这个时候就可以curl localhost:8090
