Default ports can be avoided

[akondasif]

Greetings,

We are security researchers and we are looking for insecure coding patterns and configurations in the microservice architecture repositories. In your repository, we have found instances of default port usage.

According to a recent report default port usages must be avoided: https://www.bleepingcomputer.com/news/security/most-cyber-attacks-focus-on-just-three-tcp-ports/#:~:text=According%20to%20the%20report%2C%20the,(Hypertext%20Transfer%20Protocol%20Secure).

Fix: #10

I am interested to know if you agree with the findings. Any feedback is appreciated.
