运行映像404之后的docker.Tomcat - 请求的资源不可用

Question

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

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

项目：

Dockerfile ：

FROM tomcat:8.0.41-jre8
MAINTAINER Sergii D

# fixed path for copying
COPY docker-test-02-1.0-SNAPSHOT.war /usr/local/tomcat/webapps/ROOT.war

# Routine for me - optional for your case
EXPOSE 8080

# And run tomcat
CMD ["/usr/local/tomcat/bin/catalina.sh", "run"]

1. docker build -t yourname .
2. docker run --rm -it -p 8080:8080 yourname

1. 然后我在浏览器中打开链接

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

我看到错误The requested resource is not available.

我该如何解决？

PS：如果打开192.168.99.100:8080会有样本TomCat页面，所以TomCat都可以 .PNG

Answer 1

您正在将war文件复制为Root。在docker文件中复制它时发生战争。将其复制为/ usr / local / tomcat / webapps /。或者尝试上下文ROOT。
