Terraform, apart from being an incredible tool overall, is very good for managing IAM policies: it's straightforward, easy to maintain, and very flexible. I've seen a lot of guides on using Terraform for managing infrastructure in general and IAM specifically, but I haven't seen any implementing an important but not very common feature -- validating IAM policy length. So I decided to create one.
Yet another reason why I love Linux is the ability to shoot myself in the leg and still be able to do something about it (or not). This approach allows very deep configuration and understanding of the system, but at the same time, it teaches users to be cautious of their actions. Today, I would like to tell a story about how I locked myself out of root access (easy) and fixed it afterward (not easy).
We all use git. We all are familiar with pull, push and commit commands and we don't give them too much thought apart from that. Like, what can possibly be complicated about a commit? But is it actually this simple and straightforward?
Let's find out!
Yet another reason why I love Linux: everything is a file. Today I would like to talk about the files that help us to understand the health of our accumulator batteries.
To certify or not to certify? That is a complicated question. In this post, I will speculate on the topic and share my personal thoughts on certifications in general, specifically focusing on the CKA.
Git hooks are a very handy feature in development. However, because of their local nature, configuring them from a centralized repository perspective can be challenging. In this note, I aim to find a convenient solution to this problem.
There are a lot of posts in the internet regarding which program or tool does what in Linux systems. Usually it's a brief overview of the program's functionality, a few examples, and that's it. All from the objective point of view: what we want to achieve. But there aren't so many posts discussing the algorithms in which these programs can be used. So I decided to write a quick guide you can follow to determine whether there's a problem with a server and where it is.
I love bash. A tool as trivial as command line interface (CLI, or just console) holds so many secrets, that even after 9 years of experience I still sometime find something wonderful. But today I want to talk a bit about one of my favourite tricks — aliases.
A short story about why I decided to create a personal website and blog and how I set them up and got them running. (Which turned into a manual on how to create a static website with S3 + HTTPS + custom domain name and blog for it using GitHub Pages).
How often you find yourself in the situation, when you're too bored to write a commit message? Personally, quite often. For this specific reason I finally managed to create a quick way to write commit messages.
