Facing issue in loading spring-petclinic microservices with Docker Swarm multi-node configuration

[odidev]

@arey, I have set up the multi-node deployment. I have created the docker swarm cluster by using the docker swarm init --advertise-addr <Manager node IP> command.

Next, I used the docker swarm join --token <TOKEN> <Manager Node IP>:2377 command to add the worker nodes to cluster.

I have created seven worker nodes for seven services. Then I verified the nodes by using Sudo docker node ls command.

I have created an overlay network on with docker container are going to communicate from different nodes. So, I have used docker network create -d overlay testservice command to create an overlay network.

After creating the network, I have created a docker-swarm file, which is mentioned below:

Docker-swarm file: docker-swarm.txt

Deployed the container over the docker swarm cluster using this Sudo docker stack deploy -c docker-compose-swarm.yml springpetclinic. I have checked all the container in which state by using sudo docker stack ps springpetclinic

Now, when I check the UI on local browser with https://<Any worker node IP>:<port number>. It can communicate only with the main page; The other web service is not able to communicate to other services.

Could you please share some pointers for the same? Let me know if you need any other information.

Hi @odidev
I hope you found a solution to this communication issue. I don't know Docker Swarm and unfortunately cannot help you.
