A pod consists of one or more containers that share storage and networking resources and a spec for running the container(s). These are the smallest units that can be deployed in Kubernetes. Interoperability becomes “i14y“, localization becomes “l10n”, and Kubernetes becomes “k8s”. Developers sometimes create shorthand for popular terms by taking the first and last letter of a word, the number of letters in between them, and combining it into shorthand for the word. In addition to containers, there are other important concepts to understand when getting started with Kubernetes. CPU and RAM per container), and the scaling up or down of container deployments. In simple terms, what that means is Kubernetes enables load-balancing, configuration management, configuration of storage resources, automatic resource allocation (e.g. However, that doesn’t tell us much about the specifics. The phrase “management and orchestration” gets thrown around a lot when discussing Kubernetes. Kubernetes provide the missing management and orchestration. This is where containerized workload management tools like Kubernetes come in. Modern development teams need to be able to automate and scale the process of container deployment. While using a single container doesn’t require much management and orchestration, large applications need to be able to scale. Because they are lightweight and portable, containers have surged in popularity and are vital to the development of modern microservices and web applications. Containers solve the problem of reliably running applications in different environments.
#WHAT IS KUBERNETES AND DOCKER SOFTWARE#
In a nutshell, containers are lightweight software packages that include all the dependencies an application needs to run. Since its initial release in 2014, Kubernetes - an open source CNCF graduating project with roots tracing back to Google’s development team - has become one of the most popular tools in DevOps and cloud native circles.Ī prerequisite to understanding Kubernetes is first understanding containers.
Kubernetes is a platform used to orchestrate and manage container workloads (e.g.
