Docker’s Top 10 Most Popular Blogs in 2021 – Docker Blog

As 2021 comes to an end, it’s time to look back on our top 10 most-read blogs of the year. They cover a range of topics, from updates to our subscription pricing to product announcements to security threats. Here’s a quick summary, starting with the most popular, then ordered by topic.

Updates and extensions to Docker product subscriptions

It should come as no surprise that changes to our product subscriptions — our biggest news of 2021 — was a major driver in blog readership for the year. In fact, three of the top 10 most popular blogs centered on this topic.

In the number one spot is Docker CEO Scott Johnston’s announcement on August 31, Docker is Updating and Expanding Our Product Subscriptions. Scott laid out the four subscription tiers — Docker Personal, Docker Pro, Docker Team, and Docker Business — and provided a detailed breakdown of what users need to know about each, pricing (where applicable), and the why behind the changes.

The fifth and seventh most popular blogs also deal with aspects of the changes to the subscription tiers. Coming in at number five, Steph Rifai zeroed in on the issue of Volume Management in her September 30 blog, Docker Desktop 4.1 Release: Volume Management Now Included with Docker Personal. And at number seven is a September 29 blog by yours truly examining Docker Captain Bret Fisher’s take on possible alternatives to Docker, Looking for a Docker Alternative? Consider This.

Apple Silicon News

Another big driver of eyeballs to our blog was news around developers being able to run Docker Desktop on Apple’s new M1 chip. The second most-read blog of the year is Dieu Cao’s April 15 blog, Released: Docker Desktop for Mac [Apple Silicon], announcing general availability. And coming in at number four is Stephen Turner’s February 17 blog announcing a preview, titled New Docker Desktop Preview for Apple M1 Released.

Log4j 2 Security Vulnerability

The biggest security threat of the year showed up this month, causing our developer community to scramble and work tirelessly these past few days. #HugOps to you. That’s why the third most-read blog of the year focused on fixes for the Log4j 2 vulnerability CVE-2021-44228. Justin Cormack’s blog and updates on the issue, Apache Log4j 2 CVE-2021-44228.

Responding to Your Feedback

The voice of the Docker developer community is hugely important to us. When you speak, we listen. Which is why two of the most-read blogs in 2021 were about improvements to our products in response to your feedback. 

Coming in at number six is Chris McLellan’s November 9 blog about the new Pause/Resume feature in Docker Desktop and other changes that make it easier to manage updates: Docker Desktop 4.2 Release: Save Your Battery with Pause / Resume, and Say Goodbye to the Update Pop-up. And at number nine is Dieu Cao’s April 8 blog on changes to how updates work in Docker Desktop, Changing How Updates Work with Docker Desktop 3.3. 

Preview: Docker Dev Environments

Our eighth most-read blog of the year is a tech preview that appeared back on June 23. Tech Preview: Docker Dev Environments by Ben De St Paer-Gotch dove into a powerful feature that allows developers to easily share their work-in-progress code for faster, higher-quality collaboration and code reviews.

Hear, Hear for Heredocs!

And the number 10 most-read blog for 2021 details how Docker’s BuildKit tool for building Dockerfiles now supports heredoc syntax, making it easier for developers to do things that were once difficult. The piece, titled Introduction to heredocs in Dockerfiles, was written by Justin Chadell, a member of the Docker community.

So there you have it — the top 10 most popular blogs of 2021. Here’s to an awesome year of growth and expansion in the developer community — and to more must-read blogs — in 2022.
