The aim of this page📝 is to explain count looping constructs in Terraform. Being new to HCL and its declarative nature, this looping construct/meta-argument is initially weird (there is also for_each and dynamic blocks). So, you iterate, but you also assign a value (use =) simultaneously. …

The aim of this page📝 is to explain how to manage file handles in Windows using the handle utility, based on the particular example of freeing a handle for a specific file. This happens when for example I cannot delete a git repository that I need to quickly re-clone because some program (sometimes VLC player) is having the handle open and the folder will not get deleted. The easiest is to use the handle utility from Sysinternals Suite

The aim of this page📝 is to explain how to manage monitoring policies and notification channels in the Google Cloud Platform (GCP) Console. I am learning this since the alerts we put into our applications are consumed also by the client in whose account the various Snowplow apps are running. Therefore if there are changes to alerting policies, sometimes we get follow-up questions that need to be answered even if we are managing the account autonomously via Terraform.

The aim of this page📝 is to explain AWS Identity and Access Management (IAM) based on the particular example of instance profiles. I need to learn this as I am looking at the facilitation of access between customer’s Databricks cluster and S3 buckets we are managing. — Instance profiles are a feature of IAM that allows you to pass an IAM role to an EC2 instance. When you create an IAM role from the AWS console, an instance profile is automatically created with the same name.

The aim of this page📝 is to explain the usage and functionality of the eval command in Bash scripting, based on the particular example of the expression `eval “$(/home/linuxbrew/.linuxbrew/bin/brew shellenv)”` from Homebrew for Linux installer — For terminology, see Eval Apply evaluate means get the meaning/value of the given symbol apply means execute an operation, do, things with the values, execute

USE CASE — The purpose of this page 📝 is to describe four options for performing additional configuration sometimes required after deployment that one would do with Terraform. This could be for example: Loading an app onto a Virtual Machine (VM) Configuring a Database (DB) cluster Generating files on a Network File System…

The aim of this page📝 is to explain package management and the use of package managers in different contexts, based on the particular example of installing Homebrew in a Docker container which I need to do due to the fact that I am running Windows and need to run Homebrew at work. Wrapping my head around package managers just out of curiosity. — Package managers are software tools that automate the process of installing, upgrading, configuring, and removing software packages in a consistent manner.

The aim of this page📝 is to explain the diff between the view of Cluster and Workload as encountered in GCP Console → Kubernetes Engine — Cluster offers you to configure nodes, i.e. machines that pods are running on
