Configure mongodb service

Introduction Containers are revolutionizing the entire software lifecycle: from the earliest technical experiments and proofs of concept, through development, testing, deployment and support. Introduction Want to try MongoDB on your laptop? Just execute a command and you'll have a lightweight, self-contained sandbox. You can delete all traces of what you've done when you're done. Want to use the same application stack copy in multiple environments? Build your own container images and let your development, testing, operations, and support teams use the same environment clone. Containers are revolutionizing the entire software lifecycle: from the earliest technical experiments and proofs of concept, through development, testing, deployment and support. Orchestration tools are used to manage how to create and upgrade multiple containers, and

What exactly is the reason for Kubernetes' widespread popularity?

Introduction The Kubernetes platform that runs containerized workloads plays a significant role when developing and deploying cloud-native applications. Naturally, developing and deploying cloud-native applications has become extremely popular. There are obvious advantages to a process that allows for rapid deployment and continuous delivery of bug fixes and new features, but no one talks about the chicken and egg problem: How to achieve this? Building the infrastructure and development processes to develop and maintain cloud-native applications from scratch is a non-trivial and time-consuming task. Kubernetes is a relatively new platform for running containerized workloads that solves these problems. It was originally a project within Google, and Kubernetes was developed in the 20s
