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
