I’m not one to blindly follow 1 person’s comments, but once a few people start to mention the same thing it starts to get interesting. If you go through the Reddit comments you’ll find a number of people commenting about how DNS was randomly failing in Alpine and others commented about poor runtime performance for certain types of activities (such as a web app connecting to a database). Discovering 2 Negative Trends about Alpine I’ve been using Docker for a really long time and picked up what I think are some neat patterns over the years, but I really wanted to see what others have been doing so I can improve. To be honest, that’s why I wrote the post. To my surprise it received over 150 upvotes, a 99% upvote rating and a ton of engagement from the Reddit community. What really happened was, I put together an article which went over a few Docker best practices about a month ago and it made its way onto Reddit. I definitely didn’t wake up today thinking “gee willikers, I wonder how Debian stacks up to Alpine as a base Docker image in 2018”. Why Am I Comparing These 2 Base Images Now?
I wrote about how awesome Alpine was over a year ago and have personally been using it all this time without any show stopping issues. It seems like a perfect match to run it as a base image inside of a container. It’s a super minimal distribution of Linux with an extremely small attack surface. Quick Jump: Why Am I Comparing These 2 Base Images Now? | Testing Both Base ImagesĮver since Docker announced they were gravitating towards using Alpine in their official base Docker images, I hopped on board and embraced Alpine. Updated on July 10th, 2018 in #docker Benchmarking Debian vs Alpine as a Base Docker Image Most official Docker images offer both Debian and Alpine based images but there's some surprising performance results between the 2.
