Here are some of the tasks orchestration platforms are challenged to perform. Trust me, orchestrating containers is more like herding cats than working with disciplined musicians (some claim it’s like herding Schrödinger’s cats). These mechanisms are often compared to a conductor directing an orchestra to perform elaborate symphonies and juicy operas for our enjoyment. It becomes immediately clear there must be number of mechanisms in place to coordinate such a distributed system. Hold this thought for a minute and visualize all these containers and nodes in your mind. They run on multiple host machines, called nodes. A modern application can consist of dozens to hundreds of containerized microservices that need to work together smoothly. Watch webinar now! What are the challenges of container orchestration?Īlthough Docker Swarm and Kubernetes both approach container orchestration a little differently, they face the same challenges. Docker, what they really mean is Kubernetes vs. Where Kubernetes and the Docker suite intersect is at container orchestration.
#WHAT IS KUBERNETES SIMPLE EXPLANATION HOW TO#
Rather than individually managing each container in a cluster, a DevOps team can instead tell Kubernetes how to allocate the necessary resources in advance. Organizations use Kubernetes to automate the deployment and management of containerized applications. Although Docker Swarm is also an orchestration tool, Kubernetes is the de facto standard for container orchestration because of its greater flexibility and capacity to scale. Kubernetes is an open-source container orchestration platform for managing, automating, and scaling containerized applications. Built-in container orchestration: Docker Swarm manages a cluster of Docker Engines (typically on different nodes) called a swarm.Docker Engine is built on top containerd, the leading open-source container runtime, a project of the Cloud Native Computing Foundation (DNCF).

These tools integrate tightly with code repositories (such as GitHub) and continuous integration and continuous delivery (CI/CD) pipeline tools (such as Jenkins). Docker Compose is a tool for defining and running multi-container applications.

Developer tools for building container images: Docker Build creates a container image, the blueprint for a container, including everything needed to run an application – the application code, binaries, scripts, dependencies, configuration, environment variables, and so on.It is a suite of tools for developers to build, share, run and orchestrate containerized apps. Source: ĭocker is more than containers, though. Just as people use Xerox as shorthand for paper copies and say “Google” instead of internet search, Docker has become synonymous with containers. Let’s unpack the ways Kubernetes and Docker complement each other and how they compete. However, Docker also provides a system for operating containerized applications at scale, called Docker Swarm-Kubernetes vs Docker Swarm.

Since containers are easy to replicate, applications can auto-scale: expand or contract processing capacities to match user demands.ĭocker and Kubernetes are mostly complementary technologies-Kubernetes and Docker. Operating them in production is the job of Kubernetes. A container can run anywhere, on a laptop, in the cloud, on local servers, and even on edge devices.Ī modern application consists of many containers. Creating these containers is the domain of Docker. Think of containers as standardized packaging for microservices with all the needed application code and dependencies inside.

In a nutshell, Docker is a suite of software development tools for creating, sharing and running individual containers Kubernetes is a system for operating containerized applications at scale. Is it Kubernetes vs Docker or Kubernetes and Docker-or both?

If cloud-native technologies and containers are on your radar, you’ve likely encountered Docker and Kubernetes and might be wondering how they relate to each other.
