2. 拉取Tomcat镜像

2.1 下载

# 1. 下载再启动
docker pull tomcat

# 2. 启动运行
docker run -d -p 3355:8080 --name tomcat01 tomcat

2.2 查看浏览器

notion image
  • 部署成功，测试访问没问题
 

2.3分析

# 进入容器
root@docker:/home/henggao/Desktop# docker exec -it tomcat01 /bin/bash
# 1. Linux命令少了
# 2. 没有webapps。阿里云镜像的原因。默认是最小的镜像，所有不必要的都剔除掉了
# 保证最小的可运行环境
 

2.4 修改

# 将webapps.dist中文件拷贝到webapps
root@525fcd4bc627:/usr/local/tomcat# cp -r webapps.dist/* webapps
root@525fcd4bc627:/usr/local/tomcat# cd webapps
root@525fcd4bc627:/usr/local/tomcat/webapps# ls
root@525fcd4bc627:/usr/local/tomcat/webapps# cd ..
root@525fcd4bc627:/usr/local/tomcat# cd webapps.dist/
root@525fcd4bc627:/usr/local/tomcat/webapps.dist# ls
