Mirantis CN110 Docker Swarm Application Essentials

Duration: 1 day

Industry: Information Technology

About this course


Mirantis CN110 Docker Swarm will teach you what a containerized application looks like when it is orchestrated by Docker Swarm. It covers scheduling workloads across clusters, networking stateless and stateful applications, provisioning dynamic configuration and persistent storage, and scaling highly available applications.

What is Docker Swarm?

An orchestration tool like Docker swarm manages multiple containers deployed across multiple hosts. Docker swarms provide high levels of availability to applications, which is one of the main benefits of this technology.
