I am trying to run a springboot application in airflow container but stops saying the http webserver stopped on the port. Can I run an embedded process on airflow container on a different port?

I am using Windows command to run my spring-boot application with emblemed tomcat. Beside, I need to run many console application using CommandlineRunner. Off cource I am facing port in use issue.
***************************
APPLICATION FAILED TO START
***************************
Description:
Web server failed to start. Port 8080 was already in use.
Action:
Identify and stop the process that's listening on port 8080 or configure this application to listen on another port.
I can set port in every console application but I need to run at least 10 console application at the same time.
Do I have any config or solution for application auto-change port?
You can auto generate port number to get rid from Port was already in use. just put server.port= 0 in properties or yml. It is auto generate server port in console.
application.properties
server.port= 0
application.yml
server:
port : 0
console
I have recently started exploring the microservice architecture using jhipster and was trying to install and run the jhipster-registry from docker hub. Docker shows that the registry is running, but I am unable to access it on port 8761.
Pulled the image with docker pull jhipster/jhipster-registry
Started the container with docker run --name jhipster-registry -d jhipster/jhipster-registry
Here's a snapshot of what docker container ls returns:
Am I missing something over here?
You are starting the JHipster Registry container, but you aren't exposing the port.
You can expose a port by passing the port flag -p 8761:8761 which will enable you to connect to it via localhost:8761 or 127.0.0.1:8761 in a browser.
You may need to configure some environment variables for the JHipster Registry to start correctly. These may depend on your generated app's options, such as authentication type. For convenience JHipster apps come with a docker-compose.yml file. You can start it with docker-compose -f src/main/docker/jhipster-registry.yml up, as documented.
I have created a image of spring boot gradle project by using command gradlew jibDockerBuild
I run the image by this command docker run -p 8082:8082 demo:0.0.1-SNAPSHOT.Image is running successfully on port 8082.In project application.properties server.port is 8082 only.
I am not able accesss api so I have checked in my machine whether this process is running on the port or not by command netstat -a -n -o | find "8082".No process is running on that port.
When you install Docker on Windows by Docker Toolbox by default Docker will run on 192.168.99.100 IP (DOCKER_IP).
You can access all your containers running inside docker with DOCKER_IP on your Host machine ie Windows.
Read more on it here
Regarding your mapping query
You have mapped port, which means your container port will be mapped to DOCKER_IP:PORT
If you were using Docker on Linux or Mac it will get mapped to localhost:port as in those cases Docker is running on localhost.
The same is not true for Windows at least with Docker Toolbox.
As per your configuration, you can access your application on HOST machine by hitting
http://192.168.99.100:8082
I have an ActiveMQ instance running on Docker in my local machine, and I also have a Spring Boot app running in another Docker instance. I am not able to connect to the queue from the app. Please let me know what broker URL I should give. I tried the name of Docker container and the IP of container in the following format:
spring.activemq.broker-url=tcp://172.17.0.2:61616
I ran ActiveMQ using following command:
docker run -p 61616:61616 -d webcenter/activemq
I am getting socket timeout.
You need to put the two container in the same docker network and then you can use the container name to connect to MQ.
Spring Boot app is configured (default) to run Tomcat on port 8080. This application gets deployed on AWS via BoxFuse tool and exposed at port 8080 (as expected/configured).
I have tried setting server port to 80 in boot application properties but it causes permission denied issue and the solution seems to be modifying iptables or reverse proxy. ipTables modification is not possible due to boxFuse image/env not being editable.
Question: Is there a way in BoxFuse to setup the spring boot application on port 80 without actually setting up another instance for reverse proxy? It is an overhead to setup an instance just for port correction since can't change the iptables.
Also, Is it possible that this application is run with root privileges on the AWS instance so that I do not need to modify iptables or set up reverse proxy?
There is a -ports.Name option available when deploying the application with BoxFuse.
Docs: https://cloudcaptain.sh/docs/gradle/run
Example:
boxfuse -ports.http=80 -env=test run myapprepo/myapp:0.1
Verified on local dev environment. For Mac, it should be run as a privileged command via sudo
sudo boxfuse -ports.http=80 run myapprepo/myapp:0.1
To add, works for 443 too.
