CN110:

Docker Swarm Essentials (OD)

In the CN110: Docker Swarm Essentials course, you’ll learn what a containerized application looks like when orchestrated by Docker Swarm. We’ll cover scheduling workloads across a cluster, networking stateless and stateful applications, provisioning dynamic configuration and persistent storage, and scaling highly available applications in this course intended to set a strong foundation in orchestration for all technical roles.
