I have created Microservices using Spring Boot and Eureka . I have used API Gateway for the microservices .
All the microservices ( eureka clients ) are visible on eureka server but giving an error like the below
api-Gateway port : 8999
product-service : 9001
product-detail-service : 9002
eureka-server : 8761

my docker images are created successfully and are running fine without docker-compose .
I have used networks and much more but still not resolved
Please help I am trying to solve the issue from 3 days

I have searched over stackoverflow & tried alot of solutions but with no result.
I have 2 containers one is for eureka server and another one for spring cloud gateway.
I'm running these 2 containers with docker-compose but spring-cloud-gateway didn't register to eureka server.
I'm using https. On localhost everything is working as expected but when I jumped to containers this is the problem of unregistered clients.

I'd like to use Traefik as a reverse proxy behind a Ratchet WebSocket server (3rd option suggested in deploy section).
The goal is to manage HTTPS and wss with the reverse proxy while keeping a simple HTTP and ws on the Ratchet server.
My WebSocket server exposes on port 8080, like in this example:
public function run()
{
$loop = React\EventLoop\Factory::create();
$pusher = new Pusher();
// Listen for the web server to make a ZeroMQ push after an AJAX request
$context = new React\ZMQ\Context($loop);
$pull = $context->getSocket(ZMQ::SOCKET_PULL);
$pull->bind('tcp://0.0.0.0:5555');
$pull->on('message', array($pusher, 'onEntry'));
// Set up our WebSocket server for clients wanting real-time updates
$webSock = new React\Socket\Server('0.0.0.0:8443', $loop);
$webServer = new IoServer(
new HttpServer(
new WsServer(
new WampServer(
$pusher
)
)
),
$webSock
);
$loop->run();
}
Following this post, I have been able to configure HTTPS via Traefik.
Here is my simplified docker-compose.yml:
nginx:

However, how can I now forward HTTPS/wss to HTTP/ws to the php service?
I am working on a Laravel project. I started writing browser tests using Dusk. I am using docker as my development environment. When I run the tests, I am getting the "Connection refused" error.

The following is the driver function in DuskTestCase.php class

I run the tests running the following command.
docker-compose exec php-fpm php artisan dusk
Then I get the following error.

What is wrong with my configuration and how can I fix it?
I could not find any up to date and / or working documentation and / or example on how to set this up so what I did is researching and try and error. Yet I have not been able to get it running.
Im having a config-server with the following dependencies:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-config-server</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-bus-amqp</artifactId>
<version>2.2.1.RELEASE</version>
</dependency>
The config-server has the following bootstrap.yml:
spring:
application:
name: config-server
rabbitmq:
host: ${RABBIT_MQ_HOST:localhost}
port: ${RABBIT_MQ_PORT:5672}
username: ${RABBIT_MQ_URSER_NAME:guest}
password: ${RABBIT_MQ_URSER_PASSWORD:guest}
And the following application.yml
spring:
cloud:
config:
server:
git:
uri: https://github.com/MyGit/config-repository.git
cloneOnStart: true
management:
endpoints:
web:
exposure:
include: "*"
server:
port: 8888
All my clients are having the following dependencies:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-bus-amqp</artifactId>
<version>2.2.1.RELEASE</version>
</dependency>
Their bootstrap.yml for example looks like this:
spring:
application:
name: user-service
cloud:
config:
uri: http://${CONFIG_HOST:localhost}:${CONFIG_PORT:8888}
rabbitmq:
host: ${RABBIT_MQ_HOST:localhost}
port: ${RABBIT_MQ_PORT:5672}
username: ${RABBIT_MQ_URSER_NAME:guest}
password: ${RABBIT_MQ_URSER_PASSWORD:guest}
And their application.yml like this:
management:
endpoints:
web:
exposure:
include: "*"
server:
port: 8000
eureka:
client:
registerWithEureka: true
fetchRegistry: true
serviceUrl:
defaultZone: http://${EUREKA_HOST:localhost}:${EUREKA_PORT:8761}/eureka
Im using springs #ConfigurationProperties, for example:
#Component
#ConfigurationProperties("user")
#Getter
#Setter
public class UserConfiguration {
private String role;
}

When all my services are started, at first everything seems to be fine. All services are registered with eureka, all services are callable on localhost and they can talk to each other.
But the config refresh is not working.
When I change something in my config repository and commit and push it it has no effect on my services. The configuration they have stays the same. When I manually call the bus refresh on my config-server:
http://localhost:8888/bus/refresh
with POST, like it is described in nearly every guide I could find so far, I get the response:
{
"timestamp": "2020-03-30T09:33:57.818+0000",
"status": 405,
"error": "Method Not Allowed",
"message": "Request method 'POST' not supported",
"path": "/bus/refresh"
}
When I use GET instead, I get:
{
"name": "bus",
"profiles": [
"refresh"
],
"label": null,
"version": "03759e798f3516da6a18fc8b61a265d37ddeff4e",
"state": null,
"propertySources": []
}
and it also has no effect on the confiuration of my services.
And when I call the bus refresh on any of my services I get:
{
"timestamp": "2020-03-30T09:35:39.643+0000",
"status": 404,
"error": "Not Found",
"message": "No message available",
"path": "/bus/refresh"
}
What do I need to do to get the auto configuration refresh working?
Manually calling the /actuator/refresh endpoints on the services works. They are then pulling the new config. So it seems like the rabbit mq simply is not working.
I found the solution.
Acutally my setup and configuration files are totally fine, I just called the wrong endpoint. Instead of calling:
http://localhost:8888/bus/refresh
I have to call:
http://localhost:8888/actuator/bus-refresh
This works on any service I started. It will automatically send a message to rabbitmq which will then publish the refresh to all consumers. All configurations are then updating.
Though I still dont know why bus/refresh is not working. It is used in many examples / tutorials.
I have a Spring project and use an application.yml file to run configure it. When using placeholders in the configuration file and run it as a built docker image it will not evaluate the placeholder, whereas this works fine when running the jar without docker. What could be wrong here?
