Could someone explain why tip#9 is a good idea? To me it makes more sense to build the application in the CI pipeline and use Dockerfile only to package the app.
The post is focused on Java apps but, for example, there is a distinction on runtime and SDK images in .NET Core. If you want to build in Docker, you have to pull the heavier SDK image. If you copy the built binaries to image, you can use the runtime image. I guess there could be similar situations in other platforms too.
Other than that, it looks like a decent guide. Thanks to the author.
Hi @aphyr. I'm a great fan of your work with Jepsen although I know very little about the fault tolerance of distributed systems. Are there any resources you would recommend on the subject? I am an application developer so I don't see myself writing a database in the future. Still it would be great to learn about the concepts.
Recently I have been thinking about if any of our units makes sense in cosmic perspective. Let's take speed of light for example. It's approximately 300000 km/s. But then what is a second? It's 1/60 of a minute which is 1/60 of an hour which is 1/24 of a day(and so it goes) and all those numbers are arbitrary. A day doesn't make any sense outside our planet anyway, I doubt that there is another celestial body in the universe that takes the same time to complete a rotation. Period of some natural phenomena (like atomic electron transition) sounds better as a unit but it's a really tiny period of time so we have to scale it to make it practical for us. We will use decimal numeral system to do that, another arbitrary choice. What if we had 12 fingers or 8? This can be extended to all kinds of measurements so I wonder if any of this would make sense to another civilization. What would a cosmic system of units would like? Any reading about this would be greatly appreciated.
