Giving developers speed, security, and choice

While we’re pleased with this recognition, for us it means we cannot slow down: We need to go even faster in our effort to serve developers. In what ways? Well, our developer community tells us they value speed, security, and choice:

• Speed: Developers want to maximize their time writing code for their app — and minimize set-up and overhead — so they can ship early and often.
• Security: Specifically, non-intrusive, informative, and actionable security. Developers want to catch and fix vulnerabilities right now when coding in their “inner loop,” not 30 minutes later in CI or seven days later in production.
• Choice: Developers want the freedom to explore new technologies and select the right tool for the right job and not be constrained to use lowest-common-denominator technologies in “everything-but-the-kitchen-sink” monolithic tools.

And indeed, these are the “North Stars” that inform our roadmap and prioritize our product development efforts. Recent examples include:

Speed

• Docker Init: Automatically generates Dockerfiles and docker-compose.yml files for Python, Node, and Go apps.
• VirtioFS support: 98% reduction in database import time.
• Docker Compose file watch: Automatically detects and syncs local host code changes with the container.
• vpnkit => gVisor: 5X faster container-to-host networking performance.

Security

• Docker Scout: Automatically detects vulnerabilities and recommends fixes while devs are coding in their “inner loop.”
• Attestations: Docker Build automatically generates SBOMs and SLSA Provenance and attaches them to the image.

Choice

• Docker Extensions: Launched just over a year ago, and since then, partners and community members have created and published to Docker Hub more than 700 Docker Extensions for a wide range of developer tools covering Kubernetes app development, security, observability, and more.
• Docker-Sponsored Open Source Projects: Available 100% for free on Docker Hub, this sponsorship program supports more than 600 open source community projects.
• Multiple architectures: A single docker build command can produce an image that runs on multiple architectures, including x86, ARM, RISC-V, and even IBM mainframes.

What’s next?

While we’re pleased that our efforts have been well-received by our developer community, we’re not slowing down. So many exciting changes in our industry today present us with new opportunities to serve developers.

For example, the lines between the local developer laptop and the cloud are becoming increasingly blurred. This offers opportunities to combine the power of the cloud with the convenience and low latency of local development. Another example is AI/ML. Specifically, LLMs in feedback loops with users offer opportunities to automate more tasks to further reduce the toil on developers.

Watch these spaces — we’re looking forward to sharing more with you soon.

Thank you!

Docker only exists because of our community of developers, Docker Captains and Community Leaders, customers, and partners, and we’re grateful for your on-going support as reflected in this year’s Stack Overflow survey results. On behalf of everyone here at Team Docker: THANK YOU. And we look forward to continuing to build the future together with you.

While a lot of the players in the top 10 spots have remained consistent from last year, some trends spoke volumes. It’s clear that application development demands flexibility, agility, and tools that let you bring your own tech stack. Here’s why.

No Single Language Rules Them All

Nothing is certain but death, taxes…and JavaScript. The language has claimed the top spot among popular programming, scripting, and markup languages for the 10th year running. There’s also similar stability near the top of the rankings — where the usual suspects like HTML/CSS, SQL, and Python reign supreme. We’ve discussed the leaders, but what about the remaining languages?

Overall, the sheer variety of languages used has grown substantially in the past five years. While Stack Overflow tracked the popularity of 25 different technologies in 2017, this year’s most popular technologies list featured 42!

Given that hundreds of programming languages alone exist today — with roughly 50 considered “most popular” overall — it’s interesting to see such representation. There’s truly something out there for every imaginable use case. We love variety because it encourages innovation. However, it’s also worth noting that variety can represent added complexity for developers.

Diversity in Databases and Frameworks

Similar things can be said for databases and web frameworks, where no single technology claims 50% or greater usage. Developers demand flexible tools that let them innovate, since so many technologies are highly popular:

Stack’s findings also underscore a key element of current development. Developers are using innumerable combinations of languages, frameworks, tools — and even OSes — during the development lifecycle. There’s no widespread consensus across these categories. Tech stacks are also increasingly use case driven, and not the other way around. Developers are also trying to reach even wider audiences.

The growing complexities stemming from these trends are major pain points. Therefore, having a consistent environment where you can universally build and deploy with any of your preferred technologies is incredibly valuable.

Cross-Platform Development Is Essential

Even if Windows holds the majority in personal use, there’s no clear OS winner. Developers are creating applications across a wide variety of platforms, which means that a consistent environment must be able to build and package cross-platform applications.

Our users have shared that tools like Docker Desktop, Docker Hub, and others have noticeably simplified and accelerated their cross platform development projects. It’s much easier to package all application code, dependencies, and essential components together when deploying atop varied operating systems and CPU architectures.

For experienced developers and even container newcomers, Docker CLI commands are both plentiful and usable. Alternatively, you can start, stop, and manage your containers using Docker Desktop’s Dashboard UI. Volume management and image management options are also included. Our goal is to equip all developers with the tools they need to get more done, faster — while enjoying themselves in the process.

Containers Are Going Strong

Gartner believes that 70% of organizations will be running multiple containerized apps by 2023. Momentum has definitely grown, and it’s led us to some very humbling discoveries in 2022: Docker is the #1 most loved development tool, and remains the #1 most-wanted tool.

Over 75% of devs who’ve regularly used Docker in the past year want to keep using it. More developers (37% vs. 30% in 2021) who haven’t yet used Docker are now interested. Additionally, professional developers currently view Docker as the most fundamental tool, jumping 14 percentage points since last year.

First and foremost, this couldn’t have been possible without countless contributions from our developer community. Your continual feedback across all of our products and tools has helped drive development forward — and improve developer experiences. Most new features have stemmed directly from community engagement and contributions to our public roadmap. Your collective input has been so impactful.

We also know how increasingly saturated the tooling market is becoming every day, which makes us feel even luckier to have a strong following. Thank you so much for your support, and for letting us streamline your critical daily workflows!

Developers Value Flexibility, Ease, and Stability

We’ve noticed some main themes from Stack Overflow’s 2022 Developer Survey. Firstly, there’s a massive variety of technologies currently used across the industry. Second, developers are using these technologies both because they’re essential and because they love them so much. Third, containers are becoming even more popular as teams better understand their benefits.

Docker maintains a number of tools that make development easier. Beyond our container technology, each tool supports rapid development and deployment across highly-diverse environments. You can harness your favorite tech stack without encountering hiccups.

We think this can benefit millions upon millions of developers, and we couldn’t be happier that you agree. And if you haven’t given Docker a try, remember to download Docker Desktop. Here’s looking forward to another successful year!
