Reading Time: 3 minutes Are you a DevOps Engineer or a Site Reliability Engineer? Let us try to tear the question apart 🙂 DevOps is a set of practices that automates the processes between software development and IT teams. This is to enable them to build, test, and release software faster and more reliably. It builds a culture of collaboration between teams that historically functioned in relative silo’s. The Continue Reading
Reading Time: 3 minutes Hey guys, I hope you all are doing well, I am back with another blog on custom docker instances for databases. In my last blog we saw how we can have our custom docker instance for MySQL. Similarly, in this blog we would look how we can do the same with DynamoDB, so let’s get started. So just like the scenario in previous blog, I Continue Reading
Reading Time: 2 minutes Hi folks, I am back with another blog, have you ever been in a situation where you required to set up or mimic the current MySQL instance of any environment. Well recently I have been in such a situation and my use case was to test the overall services so I decided to use minikube for service deployment as a whole, now when I had Continue Reading
Reading Time: 4 minutes In this blog, We are going to learn how Terraform keeps tracks the state of your infrastructure and configuration. With the help of an example, we will learn how can we store state file to a remote location. We can create infrastructure on a cloud in various ways using CLI, directly using UI or any automation tool like terraform etc. Then how terraform would know Continue Reading
Reading Time: 2 minutes A few days back, we got the requirement that we need to parse an HTML table through shell script and generate a report based on the contents of the table. I tried many things and after much brainstorming created a shell script that parses the HTML tables into a CSV file. I will try to explain each and every step of this script.
Reading Time: 3 minutes We have already discussed the creation of Grafana dashboards and alerts in my previous blogs. We were doing that manually. But think of, if we need to do that in more than 10 environments then we need to repeat that manual process again and again and sometimes we get frustrated by doing all these repetitive stuff. We should have some automated process for doing this. So Continue Reading
Reading Time: 3 minutes As we all know, Kafka exposes the JMX metrics whether it is Kafka broker, connectors or Kafka applications. A few days ago, I got the scenario where I needed to determine Kafka broker health with the help of Kafka stream application’s JMX metrics. It looks bit awkward, right? I should use the broker’s JMX metrics to do this, why am I looking to application JMX Continue Reading
Reading Time: 3 minutes HAWK is a Rust based Image Recognition project, which implements a two-factor authentication by using the RFID card for user identification and Image for user validation. In this project, we have used AWS services and the whole AWS infrastructure required by this project is automated using Terraform (a tool for building, changing, and versioning infrastructure safely and efficiently).
Reading Time: 3 minutes In my previous blog, we created the first Grafana dashboard. Now in this blog, we will create our first monitoring Grafana alert. Before creating monitoring alerts, we need to add the notification channel through which we will be notified. Here, we will be adding slack as the notification channel. Slack notification channel: First, open the URL http://localhost:3000 in the browser and log in to the Continue Reading
Reading Time: 4 minutes In my previous blog, we discussed the setup of Grafana-Graphite for JMX monitoring. Now we will create a first Grafana dashboard where we will create Grafana queries to visualize JMX metrics stored in Graphite. As we know, Grafana UI runs on http://localhost:3000/ by default so let’s open the URL in the browser with the default username and password which is admin: admin After login either Continue Reading
Reading Time: 3 minutes Helm is a powerful tool which can help you manage your most complex applications running on Kubernetes. It works as a wrapper on the top of Kubernetes to manage applications. This is the best possible way to find, use and share the application built to run over Kubernetes. Helm is one of the incubating projects in CNCF family The latest version of Helm is maintained by the CNCF – Continue Reading
Reading Time: 2 minutes Hi folks, in this blog I would walk you through how can we seamlessly dockerize a NodeJS app along with redis, So as we know that docker is a pretty decent way of streamlining and making the process of deployment easier, efficient and pluggable, so let’s gets started but before that, the prerequisite for the blog is a basic understanding of docker
