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:
- 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_
- 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
- Boosts your career. According to a recent Indeed report, in the last year, job postings listing Docker as a preferred skill have increased almost 50%. And the share of job searches per million including Docker has increased 9,538% since 2014.
- Makes cool tech accessible. Whether you’re building your robot, experimenting with AI, or programming a Raspberry Pi, Docker makes it easy to work with interesting new technologies.
“I really find Docker an amazing piece of open platform which lets me to convert my Raspberry Pi’s into CCTV camera using Docker containers, pushing the live streaming data to Amazon Rekognition Service for Deep Learning & Facial Recognition using a single Docker Compose file.” @ajeetsraina (Docker Captain)
- Raises productivity. It’s easier to ramp up quickly and there’s less busy-work with Docker.
“With containerized environments, my time from zero to contribution is almost non-existent. Same thing applies when switching to another project with completely different requirements. I can finally spend more time writing code and less time getting to the point of writing code. Oh! And I know it’ll work the same way in my build pipelines and prod!” @mikesir87 (Docker Captain)
- Standardize Development + Deployments. Containers drive repeatability across processes, making it easier for both dev and ops, and ultimately driving business value.
“Docker enables us to standardize our application deployment and development across On-Prem and Cloud platforms. We can now bring more value to our customers faster and standardized.” @idomyowntricks (Docker Captain)
- Makes cloud migration easy. Docker runs on all the major cloud providers and operating systems, so apps containterized with Docker are portable across datacenters and clouds.
“Currently Docker is a key piece for migration to the cloud, for that reason is the most wanted and loved platform for the architects and developers 🐋” @herrera_luis10
- Application upgrades are a lot easier. That’s true even for complex applications.
“I switched from Oracle 11g to 12c to 18c using Docker containers a few days ago. It worked absolutely painless on my Windows 10 workstation for testing purposes. I love working this way so much! Thanks Docker!” @dthater
- And, if an app breaks, it’s easy to fix. Rolling back to a known good state is simple with Docker.
“Love it because I broke my local PostgreSQL installation and decided that was the reason to switch to using a Docker compose file. Was up and running again in an hour, haven’t looked back” @J_Kreutzbender
- It’s easy to try out new apps. Testing new applications is much easier when you don’t have to build out infrastructure each time.
“I like @Docker because it allows for lightweight test drives of applications and services.” @burgwyn
Docker Captain Don Bauer said it best:
“Docker has allowed us to fail fearlessly. We can test new things easily and quickly and if they work, awesome. But if they don’t, we didn’t spend weeks or months on it. We might have spent a couple of hours or days.”
