Docker-compose: There is not are not services registered in Eureka Server

I am trying to run all microservices from a docker-compose file and I am facing issues when running the containers due to the issue that have between the Eureka discovery server and api-gateway with the other services. There is a way that can make the discover-server (Eureka) communicate with the other services? Many thanks in advance.

There is nothing wrong with the docker-compose configuration file, the first thing you need to check is that the api-gateway can access the discovery-server properly
You can go into the containers and ping or telnet to test whether the network between the containers is connected.
use docker exec -it name /bin/bash
The startup log shows that your api-gateway configuration is incorrect, as it should be
discover-server:8761//eureka no localhost
api-gateway | 2022-12-28 02:25:27.549 INFO 1 --- [nfoReplicator-0] c.n.d.s.t.d.RedirectingEurekaHttpClient : Request execution error. endpoint=DefaultEndpoint{ serviceUrl='http://localhost:8761/eureka/}, exception=I/O error on POST request for "http://localhost:8761/eureka/apps/API-GATEWAY": Connect to localhost:8761 [localhost/127.0.0.1] failed: Connection refused (Connection refused); nested exception is org.apache.http.conn.HttpHostConnectException: Connect to localhost:8761 [localhost/127.0.0.1] failed: Connection refused (Connection refused) stacktrace=org.springframework.web.client.ResourceAccessException: I/O error on POST request for "http://localhost:8761/eureka/apps/API-GATEWAY": Connect to localhost:8761 [localhost/127.0.0.1] failed: Connection refused (Connection refused); nested exception is org.apache.http.conn.HttpHostConnectException: Connect to localhost:8761 [localhost/127.0.0.1] failed: Connection refused (Connection refused)
edit 1
I pulled your api-gateway image and started
And executed
docker cp api-gateway:/app/resources/application.properties ./
Here is the configuration that went wrong
eureka.client.serviceUrl.defaultZone=http://localhost:8761/eureka
You just have to change it to
eureka.client.serviceUrl.defaultZone=http://discovery-server:8761/eureka
edit 2
Add the following configuration to api-gatway configuration file to see if it works
eureka.client.fetch-registry=true
eureka.client.registry-with-eureka=true
edit 3
I find that most of your problems are configuration file errors in the mirror
This section uses customer-service mirroring as an example
Its port is set to 0
hostname is localhost
defaultZone is localhost:8761/eureka
This is the configuration file of customer-service that I modified
# Server port
server.port = 8083
eureka.instance.hostname = customer-service
spring.application.name = customer-service
# Memory Database for development Environment
spring.h2.console.enabled=true
spring.h2.console.path=/h2-console
spring.datasource.url=jdbc:h2:mem:customerdb;DB_CLOSE_ON_EXIT=FALSE

eureka.client.service-url.defaultZone=http://discovery-server:8761/eureka
eureka.client.fetch-registry= true
eureka.client.register-with-eureka= true
This is my visit 0.0.0.0:8888/api/v1/customer/2 the returned json all working properly

Spring Boot SQL with Docker - Could not connect to adress - Connection refused

I try to implement a SpringBoot Application with a MariaDB Connection running on Docker.
But unfortunately SpringBoot is not able to connect with the DB Container.
This is my docker-compose.yml:
version: "3.4"
services:
db:
image: mariadb:10.6
environment:
MYSQL_ROOT_PASSWORD: 'admin'
MYSQL_DATABASE: 'ghp_board'
MYSQL_USER: 'ghp_board_admin'
MYSQL_PASSWORD: 'ghp_board'
volumes:
- ./data/mariadb:/docker-entrypoint-initdb.d
ports:
- "33006:3306"
frontend:
build:
context: ./frontend
dockerfile: Dockerfile
ports:
- "8081:8080"
container_name: ghp_board_frontend
volumes:
- ./frontend:/usr/src/app/ghp_board_frontend
depends_on:

mailhog:
image: mailhog/mailhog:latest
ports:
- "8025:8025"
- "1025:1025"
And this is my application.properties:
spring.datasource.url=jdbc:mariadb://db:3306/ghp_board
spring.datasource.driverClassName=org.mariadb.jdbc.Driver
spring.datasource.username=ghp_board_admin
spring.datasource.password=ghp_board
logging.level.org.hibernate.SQL=debug
spring.flyway.enabled=false
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect
The DB-Container is running. I can connect to it via docker-compose exec db /bin/bash and then mysql -u ghp_board_admin -p
But if I am running docker-compose up --build or gradlew clean build I will get the following error:
java.sql.SQLNonTransientConnectionException: Socket fail to connect to host:address=(host=db)(port=3306)(type=primary). db
Can anyone tell me what I did wrong?

Unable to connect to mysql in docker container from another docker container

I have two docker containers: mysql and spring boot service.
Service container is not connecting to mysql container(failing on the deploy) with following exception:
CommunicationsException: Communications link failure
So far I have tried using docker --link, docker networks, running everything using/without docker compose.
I am able to connect to DB container outside of docker.
Connection string: jdbc:mysql://db:3306/somedb
docker-compose.yml
version: '3.7'
services:
app:
build: .
restart: unless-stopped
ports:
- "80:8060"
links:
- db
depends_on:
- db
db:
image: "mysql:latest"
command: --default-authentication-plugin=mysql_native_password
environment:
- MYSQL_DATABASE=somedb
- MYSQL_ROOT_PASSWORD=somepassword
ports:
- "3306:3306"
volumes:
- /Users/someuser/someproject/mysql/data:/var/lib/mysql

I had the same problem earlier and i tried with by changing the mysql image version. Here is my compose yaml file where i am able to connect it with.
version: "3.0"
services:
spring-boot-container:
build: .
ports:
- "8086:8086"
links:
- mysql-standalone
mysql-standalone:
image: mysql:5.6
ports:
- "3307:3306"
environment:
MYSQL_ROOT_PASSWORD: password
MYSQL_DATABASE: springsecurity
MYSQL_USER: sa
MYSQL_PASSWORD: password

So in my service dockerfile I say:
ADD target/app-1.0-SNAPSHOT.jar /app-service.jar
RUN sh -c 'touch /app-service.jar'
But I forgot to rebuild jar after making changes in service config files
TL;DR I'm retarded

Zookeeper connection failing cp-rest-proxy with spotify kafka image

I have been using the kafka image provided by spotify to run kafka locally. I'm currently trying to use it with cp-kafka-rest and schema-registry images.
I need help resolving this issue:

You have no zookepeer container - it is actually your "kafka" service image that includes both Zookeeper and Kafka servers, so zookeeper:2181 should rather be kafka:2181
However, I would recommend not using the spotify images, as they are significantly outdated
