docker运行映像404. Tomcat – 请求的资源不可用

我需要在Docker容器中的Tomcat上收集一个简单的Java应用程序，但启动后我们有错误：

HTTP Status 404 - /docker-test-02-1.0-SNAPSHOT type Status report message /docker-test-02-1.0-SNAPSHOT description The requested resource is not available. Apache Tomcat/8.0.41

3. 然后我在浏览器中打开链接

http://192.168.99.100:8080/docker-test-02-1.0-SNAPSHOT

我看到一个错误The requested resource is not available.

我该如何解决这个问题？

PS：如果打开192.168.99.100:8080会有样本TomCat页面，所以一切正常TomCat .png

Answer 1

你正在复制你的战争文件作为根。 当你在docker文件中复制它时会发生战争。 将其复制为/ usr / local / tomcat / webapps /。 或者尝试使用上下文ROOT。
