I tried to implement an **example** of **Spring Boot Microservice** examples.
I have a problem in **docker-compose** file.

**Eureka server** and **api gateways** throws an **issue** defined below while there is no issue in config server.

Here is the issue : `com.netflix.discovery.shared.transport.TransportException: Cannot execute request on any known server`

Here is the **code snippets** **for config server**.

configserver: image: configserver container_name: configServer build: context: ./configserver dockerfile: Dockerfile environment: CONFIGSERVER_URI: "http://localhost:9191" CONFIGSERVER_PORT: "9191" ports: - "9191:9191" networks: backend: aliases: - "configserver"


Here is the **code snippets** for **eureka server**

eurekaserver: image: eurekaserver ports: - "8761:8761" build: context: ./discoveryserver dockerfile: Dockerfile environment: CONFIGSERVER_URI: "http://localhost:9191" CONFIGSERVER_PORT: "9191" EUREKASERVER_URI: "http://localhost:8761/eureka/" EUREKASERVER_PORT: "8761" depends_on: configserver: condition: service_started networks: backend: aliases: - "eurekaserver"

Here is the **code snippets** for **api gateway server**.

gatewayserver: image: gatewayserver ports: - "8600:8600" build: context: ./api-gateway dockerfile: Dockerfile environment: PROFILE: "default" SERVER_PORT: "8600" CONFIGSERVER_URI: "http://localhost:9191" EUREKASERVER_URI: "http://localhost:8761/eureka/" EUREKASERVER_PORT: "8761" CONFIGSERVER_PORT: "9191" depends_on: configserver: condition: service_started eurekaserver: condition: service_started networks: backend: aliases: - "gateway"



Here is all docker-compose.yml : Link

Hi there, I have a suspicion that you may have a misconfigured connection, but can't tell due to the lack of error messages. Could you please post the exact error messages you are seeing in your console? I did a quick search for the error
`com.netflix.discovery.shared.transport.TransportException: Cannot execute request on any known server` and several things popped up.

I removed **localhost** in this line and revised it shown below ```spring.config.import=optional:configserver:http://configserver:9191/```

I removed **localhost** in application.properties file under config server and revised mysql connection shown below.

```
spring.datasource.url=jdbc:mysql://database:3306/springbootadvertisement?useSSL=false&allowPublicKeyRetrieval=true&serverTimezone=Turkey

eureka.client.serviceUrl.defaultZone=http://eurekaserver:8761/eureka

```. I changed it but I still got the same issue.

All these are not suitable for here as there are a lot of logs for each service. Is it possible to look through screenshots if you don't mind

@datdatyul IF you do not feel comfortable posting them yourself, feel free to send me a private message with the error logs. Please copy and paste the error messages, no screenshots, or no google drive links please.

I'm trying to implement an example of Spring Cloud running in docker.
I can run all services in local but I cannot do that in docker.

again, can you please post the screenshot of them here rather than providing a link?
Also, did a bit more digging for ya, and found this nice step by step setup. Might wanna take a look to see if everything is configured correctly.

You said can you please post the screenshot of them here rather than providing a link. How can I share nearly 60 images here?
I already shared all information about my issues with you.
I was nearly one week that you cannot answer my questions.
Now, is it possible to look through my docker-compose.yml and Dockerfiles of each services and properties file under configuration folder of config server.
