unable to start Apache NiFi UI

I have created a container for Apache NiFi using a docker-compose file. When I run the docker-compose up command I get the following error when the nifi container is run:
2022-10-19 14:59:34,234 WARN [main] org.apache.nifi.web.server.JettyServer Failed to start the web server... shutting down.
nifi_container_persistent | java.io.IOException: Function not implemented
What exactly is the java.io.IOexception function? Where can I make the required change to that I can fix this error?
Here is the docker compose file for nifi with custom bridge network "my_network":
nifi:

503 error code for Springboot container connecting to mongo container using docker-compose

I am trying to connect my spring-boot application(REST endpoints) running in a Tomcat container with a mongo container. I am using docker-compose to link both the containers. The application was working perfectly fine. It just stopped working suddenly.
Following is my code:
Dockerfile:
FROM tomcat:9.0.13
WORKDIR /usr/local/tomcat/webapps
#COPY pom.xml .
#RUN ["mvn", "clean", "install"]
COPY /target/TestProfileManager.war .
docker-compose.yml:
version: '3'
services:
app:
container_name: VF-BACKEND
restart: always
build: .
ports:
- "8083:8080" #VF Webservice
depends_on:
- mongo
links:
- mongo
mongo:
container_name: VF-MONGO
image: mongo:4.0.2
ports:
- "27018:27017"
volumes:
- /data/vfdb:/data/db
application.properties
spring.data.mongodb.uri=mongodb://mongo:27018/tsp
If I run the application from the IDE as a standalone application, the endpoints do return the response. Only during container communication, I am getting 503. I could not find any post that answers my question.
Thanks for the help. Since, the code was working before, not pasting the classes. Let me know if I should share them as well.

It should be mongodb://mongo:27017, in service to service communication you do not need to use publish port.
It is important to note the distinction between HOST_PORT and
CONTAINER_PORT. the HOST_PORT is 27018 and the container port is
27017 . Networked service-to-service communication use the
CONTAINER_PORT

Creating docker container for java jersey app

I've been stuck on this for a good bit now and can't find the solution anywhere. I'm writing a java rest service using jersey framework, maven as a package manager hosted on a apache tomcat.
The project works perfectly fine locally. I want to dockerize the application and really struggling. I have the tomcat container up and running and when I go to the root of my application I can see the simple hello text I have. So when I go to http://xxx:8888/npmanager/ at this point I'm seeing what I expect.
Now when I try to hit any of my endpoints i.e https://xxx:8888/npmanager/api/XXX I get a 500 error:
warnings have been detected with resource and/or provider classes:

Why I have exception opening a socket? How to fix this problem?

You are setting mongodb host in property file as localhost. In a container localhost address itself, but your mongodb is not in that container(car-service) which car-service run in. While you are using docker compose, you can address a container with its name. In your case it is mongodb.

to clarify #barbakini's answer, to define it in applications.yaml use:
spring.data.mongodb.host: mongodb

Your mongoDB service is not UP ,
Check the status by following command
sudo service mongodb status
sudo service mongodb start
Hope it should work, there could be several reasons as well ,
like the configuration you defined in your application for mongodb service is incorrect such as port .

Try to add
network_mode: host
and remove
links: ....
for all services, that want to connect with mongo or eureka or postgresql, inside your docker-compose.yml.
By doing so you will connect to docker localhost.

Issue linking containers in Docker using Docker-compose

I'm using Docker to get my micro services architecture ready.
I'm facing some problem trying to link one container with another using docker-compose.
Basically I have a container for a postgressql image, and the a java micro service developed with spring boot that should connect to the database container.
So I'm setting a link in docker-compose.yml and referencing the db container ip as 'db' using :
- "JAVA_OPTS=-Dpostgres.host=db"
However I'm getting the following error starting the microservice with docker:
Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'postgress.host' in value "jdbc:postgresql://${postgress.host}:5432/docker"
So basically this placeholder cannot be resolved, but normally docker-composed should take care of setting this system variable to point to the db container IP address right?
What I'm doing wrong?
Below the files involved:
docker-compose.yml:
version: "2"
services:
microservices:
build: ./microservices
container_name: microservices
links:
- db
- consul
environment:
- "JAVA_OPTS=-Dpostgres.host=db"
consul:
image: consul
container_name: consul
ports:
- "8500:8500"
db:
image: postgres
container_name: local-postgres9.6
ports:
- "5432:5432"
environment:
POSTGRES_PASSWORD: docker
POSTGRES_USER: docker
application.yml of the microservice:
server:
port: 8081
project:
jdbc:
url: jdbc:postgresql://${postgres.host}:5432/docker
driver: org.postgresql.Driver
username: docker
password: docker

Try ${db.host}, according to the documentation:
Containers for the linked service will be reachable at a hostname
identical to the alias, or the service name if no alias was specified.
