docker-compose.yaml cannot work from outside the local environment.

Description

I am following the docker compose cluster tutorial from here - http://tendis.cn/#/Tendisplus/%E8%BF%90%E7%BB%B4/new_cluster_compose?id=docker-compose%e7%89%88

It works as expected. But, i want to access this cluster from outside (i deployed this docker-compose in a vm)
But, when I try to access this from outside the vm through the vm's global ip it does not work because I believe in the docker compose file there are hard coded ip address and also subnet is also 192.168.98.0/24 so when accessing it from out side it gets forwarded to 192.168.98.12 but for a global network this is not possible as 192.168.98.12 is the local ip of the virtual machine.

Expected Behavior

It should be docker host binded so when accessing from outside it should be redirected to host ip of the local machine.

Current Behavior

mentioned in the desciption

Possible Solution

something like this --network: host should be added in networks of compose file.

Steps to Reproduce (for bugs)

just run the docker-compose file on a cloud vm and try to access it from outside where the redis host is the global ip of the vm
eg.
My global ip of the cloud vm is - 40.114.118.11
But when i try to access the cluster:

However from inside the vm:

Context

Trying to deploy the cluster for PROD.

Your Environment

• Operating System and version: ubuntu 18
• Machine Specifications: 2vcpus 8gb ram 500 gb ssd
• Tendis Version:
• Tendis Configuration: docker-compose.yaml
• IO/Network used:
• Link to your project:

docker-compose.yaml is docker compose default config file.

1. if you want cloud vm access cluster. you can use redis-cli -h ip -p 30000 -a tendisplustest -c to access. because docker port 51002 mapping localhost 30000. can use docker ps -a look this.
2. if you want modify subnet. you can modify docker-compose.yaml or use helm to build cluster.
3. --network may have safe problem. and cluster node port all is 51002. cluster will build fail.

Yes, redis-cli -h 40.114.118.11 -p 30000 -a tendisplustest -c will solve the connection problem.
But when i will run the set command it will redirect to 192.168.98.22:51002 which for the global tendis cluster deployment is incorrect what should I do in such condition.
Please see the below screen shot accessing a redis cluster located in a Vm with ip - 40.114.118.11

In my env. it can work success.

you can use cluster nodes and cluster info see cluster state.
@jainal09 What is your build process?

[OMG-By]

And If you've ever failed to build. you should rm tendis tmp data dir /data/tmp/.
This might affect the new cluster env.
