Now I have the following Routes Defined in the camel-context.xml
<beans xmlns="http://www.springframework.org/schema/beans"

<route id="RESTPaymentRoute">

<!-- <throttle> -->
<!-- <constant>40</constant> -->
<to uri="direct-vm:paymentV1Rest"/>
<!-- </throttle> -->
</threads>
</route>
</beans>
I start the application with the following code
#SpringBootApplication
#EnableAutoConfiguration()
public class PaymentServiceRestApplication {
private static ClassPathXmlApplicationContext applicationContext;
public static void main(final String[] args) throws Exception {
applicationContext = new ClassPathXmlApplicationContext("camel-context.xml");
applicationContext.start();
SpringContextHolder.setStaticApplicationContext(applicationContext);
((LoggerContext) LoggerFactory.getILoggerFactory()).getLogger("org.mongodb.driver").setLevel(Level.ERROR);
}
}
The application starts up properly and it services requests normally. Now the problem arises when I package this application with docker. My docker file is as follows
FROM java:8
LABEL maintainer="babajide.apata#interswitchgroup.com"
ENV http_proxy 'http://x.x.x.x:6060/'
ENV https_proxy 'http://x.x.x.x:6060/'
ENV NO_PROXY 'localhost,127.0.0.1,0.0.0.0,192.168.10.0/24,example.com'
RUN apt-get update && apt-get install -y \
telnet
#Change OS time zone
RUN mv -f /etc/localtime /etc/localtime.bak
RUN ln -s /usr/share/zoneinfo/Africa/Lagos /etc/localtime
ADD payment-service-rest/target/service.jar.jar /opt/p-rest/service.jar
WORKDIR /opt/p-rest
EXPOSE 19080
CMD cat /etc/hosts; java -jar payment-service-rest-4.x.team5-dev.jar;
The container starts up properly but surprisingly enough when i try to access the service through the exposed port from outside the container, I can see from the logs that the requests no longer gets to the app. I can telnet from the host into the container using the exposed port successfully but the requests do not get to the app completely behoves me.
