Deploying Java webapp to Tomcat 8 running in Docker container
提问by Chris
I am pretty new to Tomcat and Docker - so I am probably missing a Tomcat fundamental somewhere in this question.
我对 Tomcat 和 Docker 还很陌生——所以我可能在这个问题的某个地方遗漏了一个 Tomcat 基础知识。
What I am trying to do is build a Docker container that runs a SpringBoot Restful web service that just returns some static data. This is all running on OSX so I am using Boot2Docker as well.
我想要做的是构建一个运行 SpringBoot Restful Web 服务的 Docker 容器，该服务仅返回一些静态数据。这一切都在 OSX 上运行，所以我也在使用 Boot2Docker。
I've written my own Dockerfile to build the container that my app runs in:
我已经编写了自己的 Dockerfile 来构建我的应用程序在其中运行的容器：
FROM tomcat:8.0.20-jre8
RUN mkdir /usr/local/tomcat/webapps/myapp
COPY /1.0-SNAPSHOT/my-app-1.0-SNAPSHOT.war /usr/local/tomcat/webapps/myapp/
This Dockerfile works fine and I am able to start the container from the created image.
这个 Dockerfile 工作正常，我可以从创建的映像启动容器。
docker build -t myapp .
docker run -it --rm -p 8888:8080 myapp
This container starts correctly and outputs no errors and displays the message saying my app was deployed.
此容器正确启动，不输出任何错误，并显示消息说我的应用程序已部署。
22-Mar-2015 23:07:21.217 INFO [localhost-startStop-1] org.apache.catalina.startup.HostConfig.deployDirectory
Deploying web application directory /usr/local/tomcat/webapps/myapp
The container also correctly has the myapp.war copied to the path described in the Dockerfile. Moreover I am able to navigate to Tomcat default page to confirm that Tomcat is running, I can also hit all the examples, etc.
容器也正确地将 myapp.war 复制到 Dockerfile 中描述的路径。此外，我可以导航到 Tomcat 默认页面以确认 Tomcat 正在运行，我还可以点击所有示例等。
To the problem, when I navigate to http://192.168.59.103:8888/myapp/getDataI get a 404. I can't quite figure out why. Am I missing something regarding a .war deploy to Tomcat?
对于这个问题，当我导航到http://192.168.59.103:8888/myapp/getData 时，我得到一个 404。我不太明白为什么。我是否遗漏了一些关于 .war 部署到 Tomcat 的内容？

You are trying to copy the warfile to a directory below webapps. The war file should be copied into the webappsdirectory.
您正试图将war文件复制到下面的目录中webapps。应将war 文件复制到该webapps目录中。
Remove the mkdir command, and copy the warfile like this:
删除 mkdir 命令，并war像这样复制文件：
COPY /1.0-SNAPSHOT/my-app-1.0-SNAPSHOT.war /usr/local/tomcat/webapps/myapp.war
Tomcat will extract the war if autodeployis turned on.
如果autodeploy打开，Tomcat 将提取战争。
回答by Saril Sudhakaran
Tomcat will only extract the war which is copied to webappsdirectory.
Change Dockerfileas below:
Tomcat 只会提取复制到webapps目录中的战争。更改Dockerfile如下：
FROM tomcat:8.0.20-jre8
COPY /1.0-SNAPSHOT/my-app-1.0-SNAPSHOT.war /usr/local/tomcat/webapps/myapp.war
You might need to access the url as below unless you have specified the webroot
除非您指定了 webroot，否则您可能需要访问如下 url

There's a oneliner for this one.
这个有一个oneliner。
You can simply run,
你可以简单地运行，
docker run -v /1.0-SNAPSHOT/my-app-1.0-SNAPSHOT.war:/usr/local/tomcat/webapps/myapp.war -it -p 8080:8080 tomcat
This will copy the war file to webapps directory and get your app running in no time.
这会将 war 文件复制到 webapps 目录并立即运行您的应用程序。
