Swarm Introduction Since its inception, the container features and mirroring features of Docker have brought a lot of convenience to devops enthusiasts. For a long time, however, Docker can only run on a single host, and its ability to deploy, run, and manage across hosts has been widely criticized. The weak cross-host capability leads directly to the tight coup

Docker-compose is an open-source Docker management tool for simplifying complex container environments.Docker-compose can easily deploy a set of environments in conjunction with Swarm and Docker process container deployments.The s

frameworks are Kubernetes, Mesos, Docker Swarm. Kubernetes is the most mature and most scalable solution on the market, occupying the largest market share. The above three orchestration frameworks are open source, and users only pay for technical support services.Between the kuber
