Recently I was working on a project which includes Terraform and AWS stuff. While working on that I was using my local machine for terraform code testing and luckily everything was going fine. But when we actually want to test it for the production environment we got some issues there. Then, as usual, we started to dig into the issue and finally, we got the issue which was quite a silly one 😜. The production server Terraform version and my local development server Terraform version was not the same.

It's no secret that MariaDB has become a popular database solution for developers over the past decade. Why? Well, one could argue that it's largely because it's open source and relational.

Docker, along with Docker Compose are the most used tools under the DevOps category, according to  The State of Developer Ecosystem 2019 survey by JetBrains. Chances are if you're using Docker/Docker Compose for deployment, you'll most likely be using them for local development as well. If you only use Docker for deployment but a virtual environment for local development, you may want to look into using Docker for development to reduce the parity between dev/prod environments, as suggested in the Twelve-Factor Methodology.

Back-end engineering nowadays may require the integration of multiple services. It is painful for engineers to install many services in their local development environment. Docker has provided an easier way to do this, but it will still require some scripting outside our code. It also has not exactly had a perfect solution if we wanted to test smaller functions or classes instead of the whole service. This problem has been addressed by Testcontainers [1].

Since being forked from MySQL back in 2009, MariaDB has become one of the most popular databases of choice for developers over the past decade. While many technologists have likely gravitated to it as a solution due to its open source roots and that it's rooted in the relational database world, that really only begins to scratch the surface of what MariaDB has to offer.

In many blockchain platforms such as Ethereum and Bitcoin, data confidentiality is a kind of excluded item in their blockchain framework. In these distributed blockchain platform transactions are executed in every participant node in the network. So, every transaction in the network can be visible to all the peers. The ledger update process through all the endorsed peers and has to reach an agreement among all before it committed successfully to the ledger. So, in this scenario creating a private record and comprises within a certain group of participants in the network is a complete “No”.

It's no secret that MariaDB has become a popular database solution for developers over the past decade. Why? Well, one could argue that it's largely because it's open source and relational. So, for developers, that basically means it's free, and we get the gist of it. But that really only begins to scratch the surface.

There are 3 steps that Kubernetes uses to enforce security access and permissions are: Authentication, Authorization and Admission. In this article we are going to consider Authentication first.

In this post my plan is to create open tcp port scanning tool, use GO and worker pool to make it very fast. Expose it via REST resource, containerise and deploy

There is often the need to check whether your production system is working as expected. Playwright is a great way to test if everything is going to plan.

Sysdig is a universal system visibility tool with support for containers. What makes Sysdig special, is that it hooks itself into the machine's kernel and segregates the information on a per-container basis.

![](https://cdn.hackernoon.com/drafts/9j1a3yra.png)
Earlier, developers simply wrote their program, built it and ran it. Today, developers need to also think of the various ways of running it whether it be as a binary on a machine (virtual most likely), by packaging it into a container, by making that container a part of a bigger deployment (K8s) or by deploying it into a serverless environment or a service mesh. However, these deployment options are not part of the programming experience for a developer. The developer has to write code in a certain way to work well in a given execution environment, and removing this from the programming problem isn’t good.

Prometheus is an open-source application monitoring and alerting software solution. It is a web application which can be deployed anywhere — in a PC, virtual machine, or even in a container. It scrapes data from the exporters (small programs convert system data to Prometheus metrics) periodically and records the real-time metrics in a time series database.

Gremlin is a leading software company focusing on chaos-test in the market. It also has a tool similar to Chaos Monkey which belongs to Netflix, but is more customized to test the system with random loads or scheduled shutdowns. In the article below we will be testing a simple Kubernetes cluster running on EKS with Chaos Test.

Python is a versatile programming language that is popular and widely used for various applications, such as data science modeling and REST APIs. However, managing and maintaining a complex Python development environment can be challenging, especially when working on large or multi-faceted projects.

Problem - How many times have we faced this problem of worrying about cleaning up after running test cases. When some of our test cases run, they might add data to our database or add files to our directory which we don’t want to worry about every time.

Podman is the command-line interface tool that lets you interact with Libpod, a library for running and managing OCI-based containers. It is important to note that Podman doesn't depend on a daemon, and it doesn't require root privileges.
