My biggest passions are learning and improving each day, in what I do and why I do it.

A few tricks and ways that we design the Dockerfile that helps us to create efficient layers for building them, pushing or pulling from repositories, but also understand why we actually really need them for preventing possible errors

I think this is one of many posts of mine about Docker and it's for a reason.

I had the opportunity to work on multiple Docker-based projects recently and had many challenges with them, so as usual, I want to share those challenges and the possible solutions to them so it could lead to faster results.

The Dockerfile and the way we…


A short manner way that describes few ideas which will allow building efficient Dockerfiles to deploy, test, and scale

After a big project of mine in Docker, I’ve had from time to time talks with friends who requested few tips regarding building a Dockerfile that will help deploy containers efficiently and would be easy to scale or test in any manner.

Not that I’m an expert or anything but I wanted to share my own personal insights after seeing few things that really gave me headaches sometimes, and from all of that this post was made.

In this post, we’re…


A short description of how to handle RT(WebRTC, RTSP, SIP, etc .. ) applications in Docker containers

Docker is one if not the most spoken tech stack in the tech industry and for several reasons.

Unfortunately in the cases of RT communications some of the information is not that wide in the open as they say, because in RT communications you need to have a deep understanding of how networking works as the basics of it, and when adding to the mix the use of Docker containers, we also need to understand more about OS and how to handle the…


A guide from top to bottom of what is networking and how it works in terms of the TCP/IP and OSI models.

The networking world is quite a fascinating subject if you ask me, it allows connecting every kind of computing device such as smartphones, TVs, computers, IoT, cars, gaming consoles, and many more to each other.

This is actually what the internet is all about, connecting endpoints together and achieving connectivity between each one to give the online experience we have today like watching Netflix, going on a run with Spotify, and again many more…

In the past, I…


In this part of the series, we’re going to see what is the best solution for building an image in a fast and elegant way.

If we go a little back to part 1 of these series, we remember that if we wanted to create an image we needed to download an image, run a container out of it, do a docker commit with all the details, and the result would be an image to use.

Right now we’re going to see how to configure a Dockerfile which is a simple text file.

You can think of Dockerfile as a…


In the previous posts, we’ve seen what are Images & Containers.

This post would discuss how can we connect to our containers, share files with it, make him share files with us, and also limit to read-only permissions.

As we discussed understood so far, Docker is an interface for managing namespaces in our OS.

In addition to local files and configurations, we can also configure network interfaces to the container and also allow files to be accessed from our OS and from the container itself, so it’s basically letting container mount sectors of our file system.

Networking of Containers

A container is usually…


In this docker series we’re going to understand what Docker actually is, what can we do with it, and deployments techniques that can be used along with it.

If you want, there’s a post I’ve done in the past about Docker but I think it wasn’t detailed as much as these series, but I do recommend checking it out for a starter.

Docker today is being used from the smallest and to the biggest scaling for many applications as of today, and I wished to make a series of it that will allow understanding of how to use it well…


From the rise of the Internet itself until today, the entire human race has had this amazing gadget which is our smartphone. The smartphone is one of many great inventions of our time which gives us the ability to play games, see videos on Netflix, write mean tweets on tweeter, and make phone calls to another destination on earth, and many more…

Isn’t that amazing? Well yes kind of, almost everyone has a smartphone today. …


A few months ago if you’ve asked me what GStreamer is I would’ve said that I don’t know anything about it, or maybe knew what it is in a very high level.

I’ve had the opportunity to work on a project which demanded a very deep understanding of GStreamer, and it’s inner parts, and it still something I’m in the progress of learning because it’s like learning a programming language.

Something that I’ve did experienced in using it is that it isn’t that easy to understand GStreamer unless you go deep regarding the thing you’re trying to build, and also…


This part of our Go series will be on the amazing Go concurrency model, and the way we can communicate between the threads.

I remember when I’ve started to learn Go, the first thing that everyone talked about is the concurrency model Go has.

For those who don’t know what concurrency is then here a brief summary for you :)

Concurrency is actually executing multiple execution units in parallel, which could share some states of data together and talk to each other, and today in programming languages in order to achieve concurrency we do that using Threads.

This is at…
