Camunda, Wont deploy to Tomcat - spring-boot

Question

I am trying to create a complete instance of Camunda (cockpit, andmin, tasklist, engine-rest, ... ).
I have created a project using their archtype and ran it successfully using maven springboot:run
But when trying to deploy the project to a Tomcat server. I face the issue of the project being inaccessible.
I have the following pom.xml
<?xml version="1.0" encoding="UTF-8"?>

I have the following application class
package com.myapplication.camunda;
import org.camunda.bpm.spring.boot.starter.annotation.EnableProcessApplication;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;
#SpringBootApplication
#EnableProcessApplication("camunda-all")
#ComponentScan("com.myapplication.camunda")
#ComponentScan("com.springboot.camunda")
public class CamundaApplication extends SpringBootServletInitializer {
public static void main(String... args) {
SpringApplication.run(CamundaApplication.class, args);
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(CamundaApplication.class);
}
}
The following application.yaml
spring.datasource:
url: jdbc:postgresql://localhost:5432/camunda_db?autoReconnect=true
username: postgres
password: postgres
driver-class-name: org.postgresql.Driver
spring.h2.console.enabled: true
camunda.bpm:
admin-user:
id: demo
password: demo
firstName: Demo
filter:
create: All tasks
server.port: 8080
server:
servlet:
context-path: /camunda-all
I have the main/resources/webapp directory empty.
I would really appreciate any help.

Answer 1

Created empty maven project
added files you posted above
adjusted db settings to my postgres
cmd: mvn spring-boot:run
Portal is accessible under http://localhost:8080/camunda-all
Then adjusted POM for external tomcat deployment (also upgraded versions and cleanup up).
Updated result here:

Answer 2

there are couple of things to do to deploy you war in camunda application server.
add required dependency in pom.xml file
<dependency>
<groupId>org.camunda.bpm</groupId>
<artifactId>camunda-engine</artifactId>
<version>7.13.0</version>
<scope>provided</scope>
</dependency>
Replace #EnableProcessApplication("camunda-all") with #ProcessApplication("camunda-all")
extend your main class with ServletProcessApplication not with SpringBootServletInitializer.
Added your BPMN file in process.xml file which is inside resources/META-INF folder.
<process-application
xmlns="http://www.camunda.org/schema/1.0/ProcessApplication"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<process-archive>
<process-engine>default</process-engine>
<resource>invoice.v2.bpmn</resource>
<resource>invoiceBusinessDecisions.dmn</resource>
<properties>
<property name="isDeleteUponUndeploy">false</property>
<property name="isScanForProcessDefinitions">false</property>
</properties>
</process-archive>
</process-application>
