Docker Certified Associate Certification Training Course - Docker Container Orchestration

The video tutorial introduces container orchestration, focusing on Docker's role in managing multiple containers. It covers Docker orchestration's capabilities, including automation, provisioning, deployment, scaling, load management, resource allocation, and health monitoring. The tutorial also discusses the design and architecture of orchestration engines, emphasizing the importance of clusters and virtual machines in building robust applications.

What is the primary purpose of container orchestration in Docker?

• To create containers from scratch

• To replace virtual machines

• To manage and schedule individual and multiple container applications

• To eliminate the need for Docker hosts

How does Docker orchestration handle a container that has stopped unexpectedly?

• It migrates the container to a different host

• It restarts the container on the Docker host

• It sends an alert to the administrator

• It deletes the container permanently

What does Docker orchestration do when application traffic increases?

• It increases the number of containers

• It reduces the number of containers

• It shuts down the application

• It redirects traffic to a backup server

In what scenario does a container orchestrator move containers between hosts?

• When a container is deleted

• When a new container is created

• When a Docker host is underutilized

• When a Docker host is over-occupied or resources are limited

What additional feature does container orchestration provide besides load distribution and resource management?

• Automatic software updates

• Data encryption

• User authentication

• Health monitoring of containers
