docker制作tomcat镜像方法
【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】
- 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
- 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

- 在当前目录下创建一个Dockerfile文件
# vim Dockfile

【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。
