Running applications in containers instead of virtual machines is gaining momentum in the IT world. What is Docker & How is it Related to Containerization What exactly is Docker and how it is related to containerization? What are the top benefits of using Docker? Why did it become so popular? And what are the statistics and successful case studies related to Docker? In this article, I will answer all these questions. Other Benefits: Kubernetes is backed by the Cloud Native Computing Foundation (CNCF), huge community among container orchestration tools, it is an open source and modular tool that works with any OS.Today, there is a buzz all around about containerization and Docker.Scalability: All-in-one framework for distributed systems.Monitoring: It supports multiple versions of logging and monitoring when the services are deployed within the cluster (Elasticsearch/Kibana (ELK), Heapster/Grafana, Sysdig cloud integration).Functionality: Kubernetes as a complex installation and setup process, but it not as limited as Docker Swarm.Applications: An application can be deployed using a combination of pods, deployments, and services (or micro-services).Key features: Easy and flexible installation, Clear dashboard, Great scaling operations, Monitoring is an integral part, Great load balancing concepts, Monitors the condition and ensures compensation in the event of failure.The main reason we have chosen Kubernetes over Docker Swarm is related to the following artifacts: Redis as preferred in-memory database/store (great for caching).PostgreSQL as preferred database system.Amazon S3) for deploying in stage (production-like) and production environments SSLMate (using OpenSSL) for certificate management.nginx as web server (preferably used as facade server in production environment).Heroku for deploying in test environments.Kubernetes as cluster management for docker containers.VirtualBox for operating system simulation tests.Docker Compose for multi-container application management)
#BENEFITS OF DOCKER AND KUBERNETES CODE#
Prettier / TSLint / ESLint as code linter.CircleCI for continuous integration (automatize development process).Respectively Git as revision control system.GitHub Pages/ Markdown for Documentation, GettingStarted and HowTo's) for collaborative review and code management tool Our whole DevOps stack consists of the following tools: Kubernetes has a broader approval, being mentioned in 1046 company stacks & 1096 developers stacks compared to Docker Compose, which is listed in 795 company stacks and 625 developer stacks. Google, Slack, and Shopify are some of the popular companies that use Kubernetes, whereas Docker Compose is used by StackShare, CircleCI, and Docker. It seems that Kubernetes with 55K GitHub stars and 19.1K forks on GitHub has more adoption than Docker Compose with 16.6K GitHub stars and 2.56K GitHub forks.
"Multi-container descriptor", "Fast development environment setup" and "Easy linking of containers" are the key factors why developers consider Docker Compose whereas "Leading docker container management solution", "Simple and powerful" and "Open source" are the primary reasons why Kubernetes is favored.ĭocker Compose and Kubernetes are both open source tools.
It handles scheduling onto nodes in a compute cluster and actively manages workloads to ensure that their state matches the users declared intentions.ĭocker Compose and Kubernetes can be categorized as "Container" tools. Kubernetes is an open source orchestration system for Docker containers. What is Kubernetes? Manage a cluster of Linux containers as a single system to accelerate Dev and simplify Ops. With Compose, you define a multi-container application in a single file, then spin your application up in a single command which does everything that needs to be done to get it running. What is Docker Compose? Define and run multi-container applications with Docker. Docker Compose vs Kubernetes: What are the differences?
