From Docker Hub

Mount volume from other container

Command to exec

Tasks

Good for short-lived containers, e.g.

batch jobs

Services

Good for long-running applications

and services

Service Scheduler

• Manage long-running applications and services• Build-in• What it does

• Load balacing• Health management• Scale-up and scale-down• Update management

• Drain ELB
