ECS Flashcards
What do ECR repository policies control?
User actions within an ECR repository
User access to the ECR repositories
What must be running on your container instances so that they can register into an Amazon ECS cluster?
The Amazon ECS container agent
What is a task definition?
Task definitions tell the services which Docker images to use for the container instances, what kind of resources to allocate, network specifics, and other details
What is an “ECS service”?
An ECS service is a mechanism that allows ECS to run and maintain a specified number of instances of a task definition.
If any tasks or container instances should fail or stop, the ECS service scheduler launches another instance to replace it.
This is similar to Auto Scaling in that it maintains a desired number of instances, but it does not scale instances up or down based on CloudWatch alarms or other Auto Scaling mechanisms.
