Your company has a set of applications that make use of Docker containers used by the Development team. There is a need to move these containers to AWS. Which of the following methods could be used to set up these Docker containers in a separate environment in AWS?
A. Create EC2 Instances, install Docker and then upload the containers.
B. Create EC2 Container registries, install Docker and then upload the containers.
C. Create an Elastic Beanstalk environment with the necessary Docker containers.
D. Create EBS Optimized EC2 Instances, install Docker and then upload the containers.
Explanation:
Answer – C
The Elastic Beanstalk service can be used to host Docker containers.
AWS Documentation further mentions the following:
Elastic Beanstalk supports the deployment of web applications from Docker containers. With Docker containers, you can define your own runtime environment. You can choose your own platform, programming language, and any application dependencies (such as package managers or tools), that aren’t supported by other platforms. Docker containers are self-contained and include all the configuration information and software your web application requires to run.

- Option B is incorrect because just creating the EC2 Container registries would not suffice. We need to incorporate some automated mechanism to take care of the function of the docker container if it fails in-between. An ElasticBeanStalk would be used for this
Note:
Option A could be partly correct as we need to install docker on EC2 instance. In addition to this, you need to create an ECS Task definition which details the docker image that we need to use for containers and how many containers to be used as well as the resource allocation for each container.
But with Option C, we have the added advantage that, If a Docker container running in an Elastic Beanstalk environment crashes or is killed for any reason, Elastic Beanstalk restarts it automatically.
In the question we have been asked about the best method to set up docker containers, hence Option C seems o be more appropriate.
