Which service should be used to deploy Docker containers on Oracle Cloud Infrastructure?

The most suitable service for deploying Docker containers on Oracle Cloud Infrastructure is Container Engine for Kubernetes. This service is specifically designed for orchestrating containerized applications using Kubernetes, which is an industry-standard platform for managing containerized workloads and services.

Container Engine for Kubernetes allows users to easily deploy, manage, and scale applications packaged in containers. It provides features like automated provisioning, scaling, and management of your Kubernetes clusters, making it efficient for handling Docker container deployments. With this service, you can leverage the power of Kubernetes to orchestrate your containers, allowing for automated rollouts and rollbacks, self-healing capabilities, and load balancing.

While the other options provide valuable functionalities within Oracle Cloud Infrastructure, they are not specifically aimed at deploying Docker containers. For example, API Gateway is used for managing APIs, File Storage Service is focused on providing scalable, managed file storage, and Streaming Service is for processing and analyzing streaming data in real-time. Hence, they do not meet the specific requirement for deploying and managing Docker containers as effectively as Container Engine for Kubernetes does.
