Running TomEE API in Docker container successful, but reverse proxy returns a 404

As shown above it says that the server startup was a success, but as shown below
The browser returns me a 404 error instead.
I have tried several options
- docker compose nginx and tomcat, expose only nginx on internet
- Docker Nginx Reverse Proxy for Protection of Docker Container
- docker after run image 404. Tomcat - requested resource is not available
However none of these solutions have worked so far for me. I personally do not use docker-compose.

I cannot seem to find the solution to this problem and am inexperienced with running a TomEE API inside a Docker container. Has anyone had this problem before and how did you solve it?
EDIT: whenever I send a curl request to the docker container
curl -X GET 0.0.0.0:8080/example/home
I get the following

Solution
I prepared a very simple war file, with an index.html and a web.xml file like this:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
id="WebApp_ID" version="2.5">
<welcome-file-list>
<welcome-file>index.html</welcome-file>
</welcome-file-list>
</web-app>
and packaged it as a war file with name example.war.
Then, I used the Dockerfile you provided in your answer with minimal modifications, basically I changed the COPY line at the end of the file:

With this Dockerfile, I created a docker image and run a container with it:
docker run --rm -p 8080:8080 local/tomee
and everything seems to work properly.
As we review in our conversation, the problem then seems to be related to the application you are trying to deploy.
The problem seems to be related to the connectivity with the database, the application is unable to start properly because it cannot connect to it.
Initially, in this specific use case, the reason was that you were trying to mount a volume in the TomEE container with the database configuration properties in a path that will not actually be available, trying to make it visible to your classpath.
To solve the issue, you can either use environment variables when running your container:
docker run -e DATABASE_PASSWORD=<your password> ...
String password = System.getenv("DATABASE_PASSWORD");
or trying mounting a volume with your properties file, assume example/database.properties:
docker run -v ${PWD}/example:/a/local/path/accesible/by/your/app
and creating your configuration properties from that file:
try (InputStream input = new FileInputStream("/a/local/path/accesible/by/your/app/database.properties")) {
Properties prop = new Properties();
prop.load(input);
// get the property value
String password = prop.getProperty("db.password");
//...
} catch (IOException ex) {
ex.printStackTrace();
}
The second problem, more general, has to do with the ability to connect from a docker container to a database installed in the host that is running the container.
In your setup you run separately nginx and tomee containers, in a network called example.
One option you could try is using the host network when running your containers. You will need to adapt your nginx upstream in consequence, but your database should be accesible as localhost.
Another possibility could be to keep the containers in the mentioned example network and configure the connection url in your app to point to the IP address of the host in the docker network. There are several ways to do that. You are using linux so a simple one could be executing ifconfig and annotating the address corresponding to the docker network, docker0. Typically it will be 172.17.0.1.
You are using Mysql and, by default, it will only listen in the 127.0.0.1 address, so you probably you will need to make the database listen to multiple network interfaces. For that purpose you can use the bind-address configuration property, setting it to 0.0.0.0, which will make the database listening into every existing network interface:
bind-address = 0.0.0.0
Please, consider review the oficial MySQL documentation and this related question or this post to obtain more information regarding this configuration.
