k8s and docker difference

k8s and docker difference:

1, the technical principle is different

Dockers is a containerized technology, K8S is a set of automated deployment tools, can be a full lifecycle management of the Dockers containers.K8S is a Google-developed container cluster management system. On the basis of Dockers technology, for containerized applications to provide deployment and operation, resource scheduling, service discovery and dynamic scaling and a number of other complete functions to improve the convenience of large-scale container cluster management.

2. Different platforms

K8S is a complete distributed system support platform with perfect cluster management capabilities, multi-expansion and multi-level security protection and access mechanisms, multi-tenant application support capabilities, transparent service registration and discovery mechanisms, built-in intelligent load balancers, powerful fault discovery and self-repair capabilities, service rolling upgrades and online support. The company also provides a wide range of services, including a rolling service upgrade and online capacity expansion, a scalable automatic resource scheduling mechanism, and multi-granular resource quota management capabilities.

Docker is an open source application container engine that lets developers package their applications and dependency packages into a portable image that can then be distributed to any popular Linux or Windows machine, as well as virtualized.

3, the architecture model is different

Docker uses a client-server architecture model, using a remote API to manage and create Docker containers.Dockeif Rongsheng.com is created through a Docker image. The relationship between containers and images is similar to that between objects and classes in object-oriented programming.

Introduction to k8s and docker:

Kubernetes is the full name of k8s. It is a complete support platform for distributed systems, with a full range of cluster management features. k8s also provides a comprehensive management tool that covers all aspects of development, deployment, testing, and operational monitoring. k8s is an open source container cluster management system that can automate deployment, scale container clusters, maintenance and other functions.

Docker is an open source application container engine that allows developers to package their applications and dependency packages into portable images and then distribute them to any popular Linux or Windows machine, as well as virtualization. The containers are completely sandboxed and do not have any interfaces to each other . Docker is an open source application container engine that allows developers to package their applications and dependencies into a portable container and then distribute it to popular Linux machines, also enabling virtualization.
