Golang is a widely used language for building scalable and reliable web applications. When it comes to Storing data (relational), MySQL is one of the old and preferred ways as a database for many organisations. This blog post will look at how to use Golang with MySQL by establishing the connection and printing the version using a simple query. In upcoming blog posts, we will see advanced operations. Prerequisites To follow along with this tutorial, you should have the following installed on your machine: ...

Last year, I started exploring and studying terraform for work. While studying, I mostly relied on Terraform plan command to check the output plan. As terraform module I was writing got bigger, the plan got bigger too, and I needed to store the plan in a file and then read & analyse the file later. For example, I want to read the plan for the following resource & store it in a file, ...

If you are Terraform user, you are pretty sure you know what the module is and must have used at least one community Terraform module. For those who don’t know what Terraform module is, Read more here If you are a pro user or part of the platform engineering or DevOps team, you probably must have written one. When you write the module for yourself or other groups, it’s essential to have documentation on how to use the module, input or output parameters, etc. ...

Hello everyone, It’s my pleasure to announce the v0.1.0 release of the Kubectl EKS Plugin. I had this of the kubectl plugin for EKS from the day I started using Amazon EKS. But I finally made it into reality and cut the first release. The mission of the kubectl EKS plugin is to simplify operations and provide easy access to cluster-related information. The first release of kubectl-eks has few but convenient functionalities. I am excited about this project and hope to see more features in the upcoming months. ...

Sometimes, When IAM user tries to register a new Virtual MFA device using Google Authenticator or similar tools, they notice the following error, Entity Already exists This entity already exists. MFADevice entity at the same path and name already exists. Before adding a new virtual MFA device, ask your administrator to delete the existing device using the CLI or API. This happens because the MFA device was created but not enabled for the users. It may happen because of various reasons. If you are a system administrator or platform engineer, this can be little pain to figure out the issue. ...

I regularly use *terraform plan -no-color* command to check the plan in a more readable way. I wrote a blog post regarding the same here. Give it a read if you haven’t already. Running this command every time is quite cumbersome. Hence I was looking for options and came across these terraform environment variables features. I can export TF_CLI_ARGS as shown below with the arg. export TF_CLI_ARGS="-no-color" Now, If I run terraform plan it will be equivalent of terraform plan -no-color ...

A few days ago, I was working on an application which consisted of a multi-container pod where I had to send a signal from container A to a process from container B within the same Pod. We know containers inside the pod already share the network namespace by default which means they technically have the same IP address. Apart from this, most things, such as other namespaces, are isolated. For example, process namespace. Containers within the same pod run their process namespace and don’t share any information with another container. ...

Often we find it difficult to visualize the Kubernetes secrets as they are base64 encoded. You will need to manually copy the encoded data and then decode it or write small custom shell scripts for the same. Fortunately, there’s a kubectl plugin to simplify this process. view-secret The plugin allows users to view the contents of a secret without having to decode it manually. Check out the project on GitHub: ...

Have you ever wondered about running kubectl commands in parallel for some of your clusters? You must have written custom shell scripts or Golang scripts to do so. Fortunately, a tool to run commands in parallel now exists, Thanks to Ahmet Alp Balkan 🙏 Check out the GitHub repo, and don’t forget to ⭐️ the repo :) https://github.com/ahmetb/kubectl-foreach kubectl-foreach Is a tool that allows users to run a kubectl command in one or more contexts (clusters) in parallel. This can be very useful when you need to perform an action on all of the resources in given contexts/clusters, such as gathering information, scaling them up or down, rolling out an update, or applying a configuration change. ...

Kubernetes and Terraform are both powerful tools for managing cloud infrastructure, but they use different configuration languages. Kubernetes uses YAML, while Terraform uses HashiCorp Configuration Language (HCL). This can make it difficult to use the two tools together, as you may need to convert YAML files to HCL in order to use them with Terraform. Sometimes when you are spinning up managed Kubernetes such as GKE, EKS and AKS, you may need to deploy Kubernetes resources via terraform. ...
