Exploring Containers: Creating a Dockerfile

Docker containers are launched using Docker images, which are built from layers of Dockerfiles. A Dockerfile is a text document that contains all the commands or instructions to create, copy, and run an image. Let’s look at what goes into creating a Dockerfile, which could be used to build a runnable Docker image.

Features of Serverless Cloud Platforms

With the advent of serverless computing, several serverless platforms have become available, precluding the requirement to provision and expose the infrastructure needed on a server-based compute environment. Let’s examine some of the features to expect in a serverless platform so you can know what to prioritize.

Choosing a Cloud Computing Platform

With so many options for cloud computing platforms, it can be tough to narrow them down. Focus on the most important features for your work: Do you want a server-based platform or serverless? What support do you need for your OS and software? What other services do you want integrated? These are the questions to ask.

What’s New in Apache Cassandra 4.0

Apache Cassandra is an open source, distributed NoSQL database based on the wide column model. The highly scalable, highly available database is great for handling large amounts of data. There is no set release date yet for the next version, Cassandra 4.0, but we do already know about several new features.

Using More Advanced Kubernetes Controllers

Kubernetes is an object-oriented framework for orchestration of Docker containers. While running basic Kubernetes objects like pods and services is essential to all Kubernetes applications, what controller to use should be based on several factors. Let’s explore some advanced controller options for additional features.

Using Basic Kubernetes Objects

Kubernetes is an object-oriented framework for orchestration of Docker containers. The Kubernetes API supports several different types of objects and provides schemas for all the objects it supports. While there are many options for different features, let’s look at some of the main Kubernetes objects and their uses.

Choosing Volumes for Kubernetes Storage

For data storage with Kubernetes, pod-based storage is not persistent, so external storage is necessary. A volume is a directory that is accessible to all containers in the pod, and it exists as long as the pod exists. Several types of volumes are supported, so let's explore some of these Kubernetes storage options.
