We will use. This hard requirement also makes it impossible to use Docker with EKS on Fargate to build container images because Fargate doesnt permit privileged containers. Through customer feedback, we have learned that many DevOps teams that manage their CD pipelines choose to run it on Amazon Elastic Container Service (Amazon ECS) or Amazon Elastic Kubernetes Service (Amazon EKS). No, youre doing it wrong. Interesting, I had seen that I could add additional non-essential containers but had read this was not recommended and to instead deploy separate services for each service. With Fargate you just need to select the amount of RAM and CPU the task requires. Thanks for contributing an answer to Stack Overflow! Once finished, youll upgrade the data plane and Kubernetes add-ons. If you want a container or set of containers that are always running (such as a web site that always need to be serving visitors), you can use an ECS Service instead of a task, and then you can take advantage of auto-scaling and replacing failed containers.
