  <p>I have already created the images for all my projects. And push it in the DockerHub. And the Docker-Compose file I also push it in the GitHub. Below is the path.</p>
  
  <p><a href="https://github.com/numery009/DockerCompose/blob/master/docker-compose.yaml" rel="nofollow noreferrer">https://github.com/numery009/DockerCompose/blob/master/docker-compose.yaml</a> </p>
  
  <p>I also deploy it on the Docker Swarm on EC2. 
  But When I try to consume my micro-services through Zuul it's not working at all. And I am getting the same "Filter Error" for my every request.</p>
  
  <p>Please help!!!.</p>
