In this tutorial, we created a Service Account with a Role and RoleBinding for read-only access to Pods. You can find the source code in the GitHub repository.

Unlike User Accounts, which are typically associated with human users, Service Accounts are designed for non-human access. They are used to grant specific permissions to applications, allowing them to interact with the Kubernetes cluster in a controlled and secure way. ...

In this tutorial, we will set up Vault Agent to generate a .env file with secrets from HashiCorp Vault. We’ll use the AppRole authentication method to securely authenticate and retrieve secrets, then write them to an environment file for use in your application. You can find the complete configuration files and setup used in this tutorial in the GitHub repository. ⚠️ Important Note: This tutorial uses Vault in development mode (-dev) for simplicity. Development mode is not secure and should only be used for testing and learning purposes. In a production environment: ...

You can see the source code of this project in the v2.0.0 tag in this repo: JsShoppingCart ...

I’m a code mentor and private programming tutor. Today, my student and I were working on event listeners in JS and I tried to teach how to make a simple and minimal shopping cart. If you are learning JS, this could be a good exercise. You can find the code here. And you can see a demo here. In this work, we added our products like this: <div class="product"> <h3>Product one</h3> <p>Price: 2000</p> <button data-id="1" data-price="2000">Add to cart</button> </div> We know that in the real world we do not do this manually and we generate them with loops using data that we have retrieved from a database. ...

I have about 4 years of experience working as a private tutor of programming.

Most of my previous students are now working around the world. ...
