I have created 4 services Eureka service, Gateway service, Authentication service and User service. Authentication and User service are routing through gateway service on port 8000 and FeignClient is used to communicate between Auth and User service for creating user and authentication.
My services are running fine on local server but when docker images are created I'm getting a Feign retryable exception error.

I am trying to create a application using Spring boot and MySQL.
The application is running successfully when working on local server, but when try to trying to create docker image the service is throwing Exception during pool initialization error.

Your port mapping for mysqldb is maybe not needed? That is unless you really want to expose MySQL's server to the outside world (outside:inside). In your case on port 3307.
ports:
- 3307:3306
I'm not sure if you really mean to expose your server, but inside of your container you should be using the real port, localhost:3306.
I solved this issue by adding the following lines in the docker-compose.yml files.
- SPRING_DATASOURCE_URL=jdbc:mysql://mysqldb:3306/bank_app?useSSL=false
- SPRING_DATASOURCE_USERNAME=root
- SPRING_DATASOURCE_PASSWORD=123456
- SPRING_JPA_PROPERTIES_HIBERNATE_DIALECT=org.hibernate.dialect.MySQLDialect
- SPRING_JPA_PROPERTIES_DDL_AUTO=update

The "process" container (the consumer) is not working.
When trying using the container CLI, the kafka consumer works fine inside the kafka container, here is the output...

Here is my Kafka Config Java file for the process microservice (the consumer)...

return listener;
}
}
How can I debug this issue? How to resolve this? There is no issue with my code clearly as it works on the IDE, then what is the problem?

I've two services, these are application.yml's:
category-service -> application.yml
spring:
application:
name: category-service
data:
mongodb:
host: categoriesdb
port: 27017
database: categoriesdb
server:
port: 8081
productcatalog-service -> application.yml
spring:
application:
name: productcatalog-service
data:
mongodb:
host: productsdb
port: 27018
database: productsdb
server:
port: 8080
And docker-compose:
version: "3.8"
services:
productcatalog-service:
container_name: productcatalog-service
image: productcatalog-service
build:
./productcatalog-service
ports:
- 8080:8080
links:
- productsdb
category-service:
container_name: category-service
image: category-service
build:
./category-service
ports:
- 8081:8081
links:
- categoriesdb
categoriesdb:
container_name: categoriesdb
image: mongo:latest
volumes:
- ./data/categories-db:/data/db"
ports:
- 27017:27017
productsdb:
container_name: productsdb
image: mongo:latest
volumes:
- ./data/products-db:/data/db
ports:
- 27018:27017
And I've a problem with running, because I get after docker-compose up:

To sum up, I'd like to run these two services using one docker-compose, each service could have one mongodb assigned to it. If my thoughts about architecture are wrong, please correct me.
Thank you for help!
it seems productsdb needs change:
productsdb:
container_name: productsdb
image: mongo:latest
volumes:
- ./data/products-db:/data/db
ports:
- 27018:27018
if you use spring boot 2.4.0 try to downgrade version to 2.3.5
I'm getting the below error while giving docker-compose up.

The error is definitely due to postgres is not running correctly or the app is not able to communicate to postgres. Use below docker-compose file and check.
version: '2'
services:
postgresql:
image: postgres:10.4
volumes:
- ./postgresql/:/var/lib/postgresql/data/

You can always use following command to check if db is accepting connection.
psql -h [HostIP] -U [db_user] -d [db_name]
I had same problem. the solution is simple.
first open docker app,
in Terminal process;
then you have to go to the directory where the docker-compose.yml
file is located.
then write docker-compose up
next, open pgAdmin app and choose db to your spring project,
next, enter the password and username found in docker-compose.yml
(username: image, password: POSTGRES_PASSWORD),
finally run the spring boot project.
