Women in Tech Week Profile: Renee Mascarinas

We’re continuing our celebration of Women in Tech Week into this week with another profile of one of many of the amazing women who make a tremendous impact at Docker – this week, and every week – helping developers build modern apps.

Renee Mascarinas is a Product Designer at Docker. You can follow her on Twitter @renee_ners.

What is your job?

Product Designer. 

How long have you worked at Docker?

11 months.

Is your current role one that you always intended on your career path? 

The designer part, yes. But the software product part, not necessarily. My background is in architecture and industrial design and I imagined I would do physical product design. But I enjoy UX; the speed at which you can iterate is great for design.

What is your advice for someone entering the field?

To embrace discomfort. I don’t mean that in a bad way. A mentor once told me that the only time your brain is actually growing is when you’re uncomfortable. It has something to do with the dendrites being forced to grow because you’re forced to learn new things.

Tell us about a favorite moment or memory at Docker or from your Continue reading

Women in Tech Week Profile: Clara McKenzie

We’re continuing our celebration of Women in Tech Week with another profile of one of many of the amazing women who make a tremendous impact at Docker – this week, and every week – helping developers build modern apps.

Clara McKenzie (center) is a Support Escalation Engineer.

What is your job?

SEG Engineer (Support Escalation Engineer).

How long have you worked at Docker?

4 months.

Is your current role one that you always intended on your career path? 

The SEG role is a combination that probably doesn’t exist as a general rule. I’ve always liked to support other engineers and work cross-functionally, as well as unravel hard problems, so it’s a great fit for me.

What is your advice for someone entering the field?

The only thing constant about a career in tech is change. When in doubt, keep moving. By that, I mean keep learning, keep weighing new ideas, keep trying new things.  

Tell us about a favorite moment or memory at Docker or from your career? 

In my first month at Docker, we hosted a summer cohort of students from Historical Black Colleges who were participating in a summer internship. As part of their visit Continue reading

Women in Tech Week Profile: Amn Rahman

We’re continuing our celebration of Women in Tech Week with another profile of one of many of the amazing women who make a tremendous impact at Docker – this week, and every week – helping developers build modern apps. 

Amn Rahman is a Data Engineer. You can follow her on Twitter @amnrahman.

What is your job?

I work as a data engineer – building and maintaining data pipelines and delivery tools for the entire company. 

How long have you worked at Docker?

2 years. 

Is your current role one that you always intended on your career path? 

Not quite! As a teenager, I wanted to become a cryptographer and spent most of my time in undergrad and grad school on research in privacy and security. I eventually realized I liked working with data and was pretty good at dealing with databases, which pushed me into my current role. 

What is your advice for someone entering the field?

Become acquainted with the entire data journey and try to pick up one tool or language for each phase. For example, you may choose to use Python to fetch and transform data from an API and load it Continue reading

Women in Tech Week Profile: Jenny Fong

We’re continuing our celebration of Women in Tech Week with another profile of one of many of the amazing women who make a tremendous impact at Docker – this week, and every week – helping developers build modern apps. 

Jenny Fong is a Senior Director of Product Marketing at Docker. Follow her on Twitter @TechGalJenny.

What is your job? 

Senior Director of Product Marketing.

How long have you worked at Docker? 

2 ½ years.

Is your current role one that you always intended on your career path? 

Nope! I studied engineering and started in a technical role at a semiconductor company. I realized there that I really enjoyed helping others understand how technology works, and that led me to Product Marketing! What I love about the role is that it’s extremely cross-functional. You work closely with engineering, product management, sales and marketing, and it requires both left brain and right brain skills. My technical background helps me to understand our products, while my creative side helps me communicate our products’ core value propositions. 

What is your advice for someone entering the field?

It’s always good to be self-aware. Know your strengths and weaknesses, and look Continue reading

It’s Women in Tech Week, and we want to take the opportunity to celebrate some of the amazing women who make a tremendous impact at Docker – this week, and every week – helping developers build modern apps.

Anusha Ragunathan is a Software Engineer at Docker. You can follow her on Twitter @AnushaRagunatha.

What is your job?

Software Engineer. I build systems, write and review code, test and analyze software. I’ve always worked on infrastructure software both at and before Docker. I participate in Moby and Kubernetes OSS projects. My current work is on persistent storage for Kubernetes workloads and integrating it with Docker’s Universal Control Plane. I also enjoy speaking at technical conferences and writing blogs about my work. 

How long have you worked at Docker?

 4 years and 1 month!

Is your current role one that you always intended on your career path? 

Yes, I’ve always been on this path. In my high school, we had the option to take biological sciences or Computer Sciences (CS). I chose CS and since then that has been my path. I earned both my bachelors’ and master’s degrees in CS.

Docker + Arm Virtual Meetup Recap: Building Multi-arch Apps with Buildx

Docker support for cross-platform applications is better than ever. At this month’s Docker Virtual Meetup, we featured Docker Architect Elton Stoneman showing how to build and run truly cross-platform apps using Docker’s buildx functionality. 

With Docker Desktop, you can now describe all the compilation and packaging steps for your app in a single Dockerfile, and use it to build an image that will run on Linux, Windows, Intel and Arm – 32-bit and 64-bit. In the video, Elton covers the Docker runtime and its understanding of OS and CPU architecture, together with the concept of multi-architecture images and manifests.

The key takeaways from the meetup on using buildx:

  • Everything should be multi-platform
  • Always use multi-stage Dockerfiles 
  • buildx is experimental but solid (based on BuildKit)
  • Alternatively use docker manifest — also experimental

Not a Docker Desktop user? Jason Andrews, a Solutions Director at Arm, posted this great article on how to setup buildx using Docker Community Engine on Linux

Check out the full meetup on Docker’s YouTube Channel:

You can also access the demo repo here. The sample code for this meetup is from Elton’s latest book, Learn Docker in a Month of Lunches, an accessible task-focused Continue reading

Docker Release Party Recap

We Celebrated the Launch of Docker Enterprise 3.0 and Docker 19.03 Last Week

Last week, Docker Captain Bret Fisher hosted a 3-day Release Party for Docker 19.03 and Docker Enterprise 3.0. Captains and the Docker team demonstrated some of their favorite new features and answered live audience questions. Here are the highlights (You can check out the full release party here).

Docker Desktop Enterprise

To kick things off, Docker Product Manager Ben De St Paer-Gotch shared Docker Desktop Enterprise. Docker Desktop Enterprise ships with the Enterprise Engine and includes a number of features that makes enterprise development easier and more productive. For example, version packs allow developers to switch between Docker Engine versions and Kubernetes versions, all from the desktop.

For admins, Docker Desktop Enterprise includes the ability to lock down the settings of Docker Desktop, so developers’ machines stay aligned with corporate requirements. Ben also demonstrated Docker Application Designer, a feature that allows users to create new Docker applications by using a library of templates, making it easier for developers in the enterprise to get updated app templates – or “gold standard” versions like the right environment variable settings, custom code, custom editor settings, Continue reading

10 Reasons Developers Love Docker

Developers ranked Docker as the #1 most wanted platform, #2 most loved platform, and #3 most broadly used platform in the 2019 Stack Overflow Developer Survey. Nearly 90,000 developers from around the world responded to the survey. So we asked the community why they love Docker, and here are 10 of the reasons they shared:

ROSIE the Robot at DockerCon. Her software runs on Docker containers.


  1. It works on everyone’s machine. Docker eliminates the “but it worked on my laptop” problem.

“I love docker because it takes environment specific issues out of the equation – making the developer’s life easier and improving productivity by reducing time wasted debugging issues that ultimately don’t add value to the application.” @pamstr_

  1. Takes the pain out of CI/CD. If there is one thing developers hate, it is doing the same thing over and over.

“Docker completely changed my life as a developer! I can spin up my project dependencies like databases for my application in a second in a clean state on any machine on our team! I can‘t not imagine the whole ci/cd-approach without docker. Automate all the stuff? Dockerize it!” @Dennis65560555 

  1. Boosts your career. According to a recent Continue reading

2018 Docker Community Awards



The Docker community has been at the heart of Docker’s success from the start. We are constantly in awe of the dedication and passion of the practitioners – users, customers, partners, contributors and maintainers – who make up our community. Early in December at DockerCon Barcelona we were humbled to honor a Docker Captain and a few very special Community Leaders whose activities over the past year have made a tremendous difference to us all. Together, the Docker Community has achieved so much, we can’t wait to see what 2019 has in store.

Tip of the Captains Hat Award

Bret Fisher


Docker Captain (and Community Leader) Bret Fisher was nominated to receive this inaugural award by his fellow Captains because his contribution and leadership serve as an example of what it means to be a Docker Captain. Bret teaches Docker to thousands of people through his Docker Mastery online course, conference workshops, and ask-me-anythings on YouTube Live. He is accessible and constantly sharing knowledge with the community and the Captains, and he helps drive improvements up and down the software stack of both Docker open source and Docker commercial products. In Bret’s own words:

“I’m so proud Continue reading
