docker制作tomcat镜像方法及异常处理

作者：风逸柏

在Docker中创建一个Tomcat镜像是一个常见的需求,尤其是在开发、测试和部署Java Web应用程序时,这篇文章主要介绍了docker制作tomcat镜像方法及异常处理的相关资料,需要的朋友可以参考下

【说明】

制作tomcat镜像，需要在官网下载tomcat binary压缩包。

tomcat官网：https://tomcat.apache.org/download-90.cgi

【配置方法】

  1. 新建一个/opt/tomcat/目录，将下载tomcat与jdk安装包上传并解压缩：
# mkdir -p  /opt/tomcat;   cd  /opt/tomcat
#ls 
apache-tomcat-9.0.93.tar.gz     jdk-8u144-linux-x64.tar.gz   Kylin-Server-V10-SP3-2403-Release-Docker-init-20240426-X86_64.tar.xz
# tar -zxvf  apache-tomcat-9.0.93.tar.gz
# tar -zxvf  jdk-8u144-linux-x64.tar.gz
  1. 提供制作镜像的base镜像，此次使用Kylin-Server-V10-SP3-2403-Release-Docker-init-20240426-X86_64.tar.xz
# docker load  -i  Kylin-Server-V10-SP3-2403-Release-Docker-init-20240426-X86_64.tar.xz
# docker images
[root@localhost tomcat]# docker images
REPOSITORY                                                                        TAG                 IMAGE ID            CREATED             SIZE
cr.kylinos.cn/v10sp3-2403/kylin-server-v10-sp3-2403-general-alpha20-x86_64-init   202405              6bd24f9f88c3        3 months ago        246MB
  1. 在当前目录下创建一个Dockerfile文件
# vim Dockfile
FROM cr.kylinos.cn/v10sp3-2403/kylin-server-v10-sp3-2403-general-alpha20-x86_64-init:202405

【异常处理】

问题1：/opt/apache-tomact-9.0.50/bin/catalina.sh: permission denied.

解决方案：程序没权限执行catalina.sh脚本。在Dockerfile中新增一行：RUN chmod +x /opt/apache-tomcat-9.0.93/bin/catalina.sh

问题2：Error: Could not find or load main class org.apache.catalina.startup.Bootstrap

解决方案：构建镜像用的tomcat.tar.gz是src源码包，需要使用binary包。
