Congrats on being featured on daily.dev! Good job there.

Thank You so much Nimrod Kramer :)

Nice article Apoorv! Keep them coming!

Thanks Matt Moll.

I will for sure! I have quite a few ideas in my head that are soon coming on my blog 😊

Apoorv Tyagi Thanks for the great article. Wondering what is the use of this docker run -dp 5000:5000 hello-python. Since we specify that we want to expose the port 5000 in dockerfile.

Apoorv Tyagi Thanks. just another small question why :5000 next to 5500 if port is 5500

Kannan 5500 is the container port that we published. Publishing ports means mapping container ports to the host application(my flask app in this case) so that the ports are available to services outside of Docker container.

In order to do that the syntax is docker run -p <your container port>:<host app exposed port><imageName>

This means anyone connecting to the host(flask app) over port 5000 will be routed to my container via port 5500.

Apoorv Tyagi Got it. Thanks for the detailed explanation.
