Introduction The advent of cloud-native computing has greatly transformed the landscape of building and distributing software. You have various tools to facilitate everything from integrating and packaging application code to deploying and scaling it. The practice of doing this is known as DevOps, and the concept that sits at the heart of modern-day DevOps is […]
With Docker containerization and service-oriented design, applications can be broken up into manageable, functional components, packaged individually with all of their dependencies, and deployed on irregular architecture easily. In this guide, we will discuss the benefits of containerization and how Docker helps to solve many of the roadblocks that stand in the way of easily moving your application through the development cycle.
Learn how to deploy and scale a Node.js application with MongoDB on Kubernetes using Helm, including replicas and autoscaling.
Docker Compose adalah alat yang memungkinkan Anda untuk menjalankan lingkungan aplikasi multikontainer berdasarkan definisi yang ditetapkan dalam berkas YAML. Alat ini menggunakan definisi layanan untuk sepenuhnya membangun lingkungan yang dapat disesuaikan dengan penggunaan beberapa kontainer yang dapat berbagi volume data dan jaringan. Dalam panduan ini, kami akan menunjukkan cara menginstal Docker Compose pada server Ubuntu 20.04 dan cara memulainya menggunakan alat ini.

In this guide, you will build a small web application and then use Kustomize to manage your configuration sprawl. You will deploy your app to development and production environments with different configurations. You will also layer these variable configurations using Kustomize’s bases and overlays so that your code is easier to read and thus easier to maintain.
