_Docker Captains are select members of the community that are both experts in their field and are passionate about sharing their Docker knowledge with others. “Docker Captains Take 5” is a regular blog series where we get a closer look at our Captains and ask them the same broad set of questions ranging from what their best Docker tip is to whether they prefer cats or dogs (personally, we like whales and turtles over here). Today, we’re interviewing Gianluca Arbezzano who has been a Docker Captain since 2016. He is a Senior Software Staff Engineer at Equinix Metal and is based in Italy. _
How/when did you first discover Docker?
At this point, it is not easy to pick a date. Four years ago I was in Dublin away from my home town near Turin. The Docker Meetup along with many other meetups were a great opportunity for nerds like me looking for new friends and to grab free pizza while having a good time. Back then I was working for a company that helps businesses move to the cloud. I saw that Docker was a powerful tool to master. Not only was Docker a useful tool and led me to meet a lot of cool people, but it also helped me to become a better open source citizen and enabled me to have some awesome experiences.
What is your favorite Docker command?
I am an old-style Docker user. Many of the new cool commands are unknown to me. One of the powerful combos I use from time to time is still “docker rm -fv $(docker ps -aq)”– I know, there are better ways! It clearly shows how powerful a good CLI tool and the UNIX philosophy are. I love buildkit, so buildx is also something I use a lot.

Today, we’re interviewing Elton Stoneman who has been a Docker Captain since 2016. He is a Container Consultant and Trainer and is based in Gloucestershire, United Kingdom.
I was consulting as an API Architect, building out the backend services for a new Android device. My role was all about .NET services running in Azure, but we worked as a single team – and the people working on the operating system were using Docker to simplify their build tools.
I started looking into their setup and I was just stunned at how you could run complex software with a single Docker command – and have it run the same way on any machine. That was way back in 2014, Docker was version 0.7 I think and I created my Docker Hub account in August of that year. Then I started blogging and speaking about Docker, and I’ve never looked back.

Multi-architecture images are hugely powerful. I work with a lot of platforms now but my heart is still in .NET. The latest .NET runtime works on Windows and Linux on Intel and Arm CPUs, and I love how you can target your apps for different infrastructures, using the same source code and a single Dockerfile.

Following the second video about Docker basics, in this video, I explain Docker architecture and explain the different building blocks of the docker engine; docker client, API, Docker Daemon. I also explain what a docker registry is and I finish the video with a demo explaining and illustrating how to use Docker hub
In this video lesson you will learn:

Today, we’re interviewing Nuno do Carmo who has been a Docker Captain since 2019. He is a Sr System Analyst for a pharmaceutical company based in Switzerland and he is based in Montreux.
Back in 2015, I was hanging with friends and we would meet once a week to check on technologies and we found out a training on Pluralsight, given by a certain Nigel Poulton, and we decided to “temporarily” download it, cough.
Both the training method from Nigel and the technology of Docker were an instant hit for us. We started to learn as hobbyists and fast forward, I guess I took it more at heart than my friends, haha.

If you have recently come across the world of containers, it’s probably not a bad idea to understand the underlying elements that work together to offer containerisation benefits. But before that, there’s a question that you may ask. What problem do containers solve?
After building an application in a typical development lifecycle, the developer sends it to the tester for testing purposes. However, since the development and testing environments are different, the code fails to work.
Now, predominantly, there are two solutions to this – either you use a Virtual Machine or a containerised environment such as Docker. In the good old times, organisations used to deploy VMs for running multiple applications.
So, why did they started adopting containerisation over VMs? In this article, we will provide detailed explanations of all such questions.
