If you are working on a project, managing its Dockerfiles can be done without too much fuss. Updating them manually is doing it the hard way. If you have 100 or 1,000 servers, though, that’s not fun.

I’d say it’s even fun, but that might just be me. If you have a couple of servers, it’s easy to keep them all up to date. When that’s done, you restart, and while your machine is reloading with its shiny new kernel, you reflect on how you’ve protected your computer from the scourges of the internet for another week. Every so often, you go onto your rig, check to see what is new and apply the updates. Anyone who has run a Linux desktop or server should be familiar with running package updates. That’s where things get hard.įor most of my career, I have been a Linux user.

That’s where you’re forced to invest time in developing and maintaining your Dockerfiles. Sure you can address all these points with Dockerfiles, but that’s where the complexity is introduced.

The unknown: Are you sure that you’re following all the best practices?.

Additional software: What if you need Tomcat to run your application?.

Who doesn’t? That means you need smarter layering, caching and possibly even multistage builds.

Speed: You probably want faster build times.

You can’t do that, at least not without rebuilding your image or totally overriding the command.

Flexibility: Your operations team might want to use the image, but to use it, they’ll need to pass in different arguments to the entry-point command.

Security: Your security team will have a problem with images generated using this Dockerfile because they’ll run as root.

There are some things wrong with this approach, though: Seems simple, right? It is, and on some level, it works to get the job done. Here’s an example to illustrate this point:ĮNTRYPOINT What’s so hard about Dockerfiles? Nuance. If you’re an application developer writing Dockerfiles, you are doing it the hard way, whether you realize it or not. I could tell you about the easy way right now, but, like my elementary school math teacher, I’m going to tell you about the hard way first. I just want to do this with minimal effort.

Despite this, I do absolutely need to get my software packaged into a container image so it’s easy to distribute and easy to use. This might sound like something you’d see on a bumper sticker, but I’d rather be coding. At the end of the day, though, it’s not where I want to spend my time. I’m glad I learned about them I’m glad I have some experience with them and I’m glad I understand how they work. This has been my experience recently with Dockerfiles. At the same time, an accountant isn’t going to perform long division to balance a company’s books they’ll use a computer to ensure the math is correct. Learning things the hard way can bring a greater understanding of your task and a greater appreciation for your tools. However, learning a process isn’t a waste of time. I don’t know how much time we spent on long division, but I do know how much time I’ve spent doing long division since I got a calculator, and that is none. She explained the concept of long division and proceeded to make my classmates and me perform long division on the chalkboard, on homework, on tests, and we always had to show our work. When I was in elementary school, my math teacher played a trick on me.
