redis-client | a simple GUI tool for Redis | Command Line Interface library

I'm trying to install Redis on Kubernetes environment with Bitnami Redis HELM Chart. I want to use a defined password rather than randomly generated one. But i'm getting error below when i want to connect to redis master or replicas with redis-cli.

Recently I have been using spring-boot-starter-data-redis;

I use spring-boot-version:2.3.8.RELEASE;

application.yml

After upgrading the vertx-redis-client to version 3.9.4 according to Vert.x documentation

The connection code was needed to be updated to conform the newer version. The code based on the example from the documentation above and looks like this:

In node.js, my entrypoint segment (app.js) calls another segment after the express session has been set up. The segment called is expecting a session field in the request ('req') object but it isn't there.

This is app.js in full:

I have 2 hosts, a web unit (WU) and a computing unit (CU). On the WU, I have my website. On the CU, I have a redis server and a (C++) app that does some computing.

The user enters input data in the website, and then I want to enqueue a job from the WU to the Redis server on the CU. I have then a worker on the CU which performs a task.

Now, I am able to enqueue a job from the WU (outside of any docker image) to the CU from the terminal (using the python rq module). However, my website is in a docker image, and I can't get it working. From within the docker image, I try to connect to 172.17.0.1:6370 (172.17.0.1 is the IP of the gateway between the image and the docker host). The error I get is connection refused. Then I thought I might have to map the ports in my docker-compose file: 6739:6739. However, then I got an error saying the port is already used. And indeed, it is used by the stunnel4 service which allows me to enqueue jobs from the WU to the redis server on the CU.

Should I run the stunnel4 service in the docker image are something? And if so, how could I do that? Or should I tackle my problem in a different way?

Network structure

WU and CU are 2 (virtual) machines. My redis server is on CU and not in a docker container. I am able to connect to the redis server from WU to CU by means of the python redis module (but not from within a docker container). I had to set up a stunnel4.service for that (redis-client on WU and redis-server on CU).

I'm following this tutorial.

In my case I am operating in a Docker environment, and I have a secured site (i.e. https://localhost). which requires secured ssl communication.

I adjusted the web, and celery containers for secure connection.
But I don't know how to configure the Redis container for secure connection with ssl
Note that when I run without ssl connection in the web and celery containers, the connection is fine.

How do I configure and run redis with ssl?

Thanks

EDIT:

I followed this tutorial to set redis with ssl and this tutorial to set redis with ssl via stunnel in Docker container.

I successfully tested the connection from my localhost to the redis docker container, by invoking redis-cli from localhost (via stunnel) to the redis docker container, using the following call from the localhost:
