From Python to Go 012. Processing User Input From CLI Arguments And Standard Input.
Hello my friend,
Whenever we develop any network and IT infrastructure automation applications, we need to have some options to provide user input. In previous blog posts in these series we already covered how to provide user input via environment variables and files. Whilst these two approaches can cover majority of your use cases, especially if you develop containerized applications running in autonomy, there are still two options we would like to talk today about.
Why To Bother Learning Automation?
For many years I was doing network design and operation without automating it (or at least without structured approach to automate it). And there are still loads of such job positions out there. And I see it based on the audience of my blog: majority of people here for networking knowledge, much less are for automation topics. From pure pragmatic standpoint of writing popular blogs, I should stick to network technologies, especially something fancy as SD-WAN and others. However, from the direction of the technologies development, I see that value (including jobs) comes from intersection of domains: networking, compute, storage, software development, data bases, Kubernetes, observability, etc. I’m of a strong opinion that engineers these days must be aware of Continue reading
