This article introduces the relevant knowledge of "what is the meaning of docker container layout". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Container orchestration refers to the process of organizing the work of individual components and application layers. Applications typically consist of individually containerized components (often referred to as microservices) and must be organized sequentially at the network level so that they can run as planned. The process of organizing multiple containers in this way is called container orchestration.

In modern development, integrated applications have long been a thing of the past, and today's applications are composed of dozens or even hundreds of loosely combined container components, which need to cooperate with each other. in order to make the established application operate according to the design.

The main way docker containers are used for container orchestration at the data center level is Docker Swarm. The open source strategy adopted by Kubernetes has won a large number of users in the ecosystem.

All container orchestration engines allow users to control when containers start and stop, group them into clusters, and coordinate the process of application composition. Container orchestration tools allow users to guide steps such as container deployment and automatic updates, health monitoring, and failover.

Docker swarm mode

If you are a new container user, you can start with Docker, which is the first container program to attract a large number of users. If you are using Docker, then Docker swarm is a natural choice, which is designed and developed by Docker developers.

In Docker version 1.12, the goal of Docker is the built-in container orchestration feature, called docker swarm mode. The independent choreographer in the Docker Swarm,Docker software stack has affected this built-in choreographer. Swarm mode allows users to control the entire lifecycle of containers, not just container cluster management and scheduling.

Kubernetes

Kubernetes was originally developed by Google as an open source container management tool. Since the launch of Kubernetes, it has been ported to Azure, DC/OS, and almost any cloud platform you can name. The only exception is Amazon Web Services (AWS), although CoreOS has helped users deploy Kubernetes clusters on AWS.

Mesosphere Marathon

Marathon is a container orchestration platform designed for Mesosphere DC/OS and Apache Mesos. DC/OS is a distributed operating system based on Mesos distributed system kernel. Mesos is an open source cluster management system. Marathon provides administrative integration between stateful and container-based stateless applications.
