自定义tomcat镜像上传至DockerHub

Lance1123 2021-07-13 11:24 原文

一）制作属于自己的tomcat镜像

  • 1.准备镜像文件tomcat压缩包、jdk压缩包

  • 2.编写dockerfile文件、官方命名Dockerfile、以官方命名时不需要-f指定、build时会自动寻找这个文件

创建个reademe.txt用来对Dockerfile做解释说明
[root@xiaozhang1999 tomcatfile]# touch readme.txt
创建镜像 ADD会自动解压包

FROM centos
MAINTAINER ztsq<467605642@qq.com>

COPY readme.txt /usr/local/readme.txt

ADD apache-tomcat-8.5.64.tar.gz /usr/local
ADD jdk-8u281-linux-x64.tar.gz /usr/local

RUN yum -y install vim

ENV MYPATH /usr/local

WORKDIR $MYPATH

ENV JAVA_HOME /usr/local/jdk1.8.0_281
ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tool.jar
ENV CATALINA_HOME /usr/local/apache-tomcat-8.5.64
ENV CATALINA_BASH /usr/local/apache-tomcat-8.5.64
ENV PATH $PATH:$JAVA_HOME/bin;$CATALINA_HOME/lib;$CATALINA_HOME/bin

EXPOSE 8080

CMD /usr/local/apache-tomcat-8.5.64/bin/startup.sh && tail -F /usr/local/apache-tomcat-8.5.64/bin/logs/catalina.out

  • 3.构建镜像

docker build -t diytomcat

  • 4.启动tomcat镜像 设置test挂载目录和日志tomcatlogs目录

docker run -d -p9090:8080 --name ztsqtomcat -v /root/tomcatfile/diytomcatcontainer/test:/usr/local/apache-tomcat-8.5.64/webapps/test -v/root/tomcatfile/diytomcatcontainer/tomcatlogs/:/usr/local/apache-tomcat-8.5.64/logs diytomcat

  • 5.进入tomcat、该容器下有tomcat和jdk。配置成功。且访问curl localhost:9090.

docker exec -it 504599f541e8ff21f571684 /bin/bash

  • 6.在浏览器上访问

7.发布项目（由于做了卷挂载、我们直接在本地上编写项目就可以进行发布了）。在test挂载目录上操作。
在test下新建WEB-INF文件夹、webinf下新建web.xml

8.测试页面

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
	<br>傻逼覃玉枭</br>
<%
system.out.println("test logs");
%>
</body>
</html>

二）上传到DockerHub

  • 1.注册https://hub.docker.com/账号并登录、这里我的注册名为lanceee。在下面会用到。

[root@xiaozhang1999 /]# docker login -u lanceee

  • 2.发布镜像到DockerHub、自己发布的镜像尽量带版本号。不带版本号默认最新latest版本

报错信息：denied: requested access to the resource is denied
解决办法：REPOSITORY下创建的镜像名改为:username/images name
报错信息：The push refers to repository [docker.io/lanceee/diytomcat]
An image does not exist locally with the tag: lanceee/diytomcat
解决办法：docker tag image id username/images name:tag
docker push lanceee/diytomcat:666

去dockerhub上查看、验证是否成功
