docker - 为什么在运行docker tomcat之后看不到Tomcat？

Question

我对Docker非常陌生。我遵循本教程:https://stackjava.com/docker/huong-dan-cai-apache-tomcat-bang-docker-sua-port-username-password.html
我的命令

docker pull tomcat
docker run -it tomcat
docker ps -a
docker inspect -f '{{json .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' 5e55df1c76bb

docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' 5e55df1c76bb

docker inspect 5e55df1c76bb

docker inspect --format="{{json .NetworkSettings.Networks}}"  5e55df1c76bb

172.17.0.2

但我访问: http://172.17.0.2:8080什么都看不到

如何在Web浏览器上查看Tomcat的结果？

Answer 1

我认为您所指的教程有些过时了。您可以使用以下命令运行tomcat docker容器

docker run --rm --name tomcat-server -p 8080:8080 tomcat:latest

在http:// localhost:8080上访问tomcat
进一步的信息是 here。由于 webapp文件夹为空，因此最初会得到404。您可以引用 this文档，该文档应有助于运行基本的Tomcat安装。然后，您可以从所引用的原始教程的第3步中进行操作。

docker exec -it tomcat-server /bin/bash
mv webapps webapps2
mv webapps.dist/ webapps
exit
