Hello, is this an open issue? I would be happy to work on it

[bradmccoydev]

Yes i have assigned to you!

[Kalpesh-18]

Hey, thanks for the assigning the issue. It would be great if you could briefly describe what you mean when you mention "optimized and better security."

I guess no one is working, Can I work on it?

[bradmccoydev]

Hey @i-am-yuvi sure no problem

[i-am-yuvi]

Hey @bradmccoydev, I would like to suggest some changes:

1. How about using a more lightweight base image golang:1.16-alpine3.14 which will eventually reduce the size of docker image
2. We can also run the application as the non-root user to reduce the vulnerabilities that could occur if it run as a root user.

# Add a new user
RUN adduser -D myuser
