I have an aws ecs fargate cluster. it is a ecs-fargate cluster not an ecs-ec2 cluster. And I am running some containers where I need to mount a volume. Is it possible to mount an s3 bucket to this fargate container?
If so, how can I do that?
If not, what are the other options I can follow? I want to preserve these data for later use (for disaster recovery and also for later access)
As mentioned in the comments, mounting S3 is a bad idea, and it won't work in your Fargate containers anyway. Currently the only option for mounting external volumes in Fargate is to use Amazon EFS.

I am trying to connect the same EBS to multiple ECS instances running on Fargate. I have a Docker container of my app, the ECS Task and ECS Service are working as expected, but I can't find any way to connect EBS to the ECS Task.
Note: The app instances synchronize writes through a common agent so there won't be a problem with regards to concurrency.
You can't do that. It is not possible. EBS only works with EC2 instances. EBS is not supported by Fargate (at this time). You would need to use EFS with Fargate.
I am using a manually created Kubernetes Cluster (using kubeadm) deployed on AWS ec2 instances (manually created ec2 instances). I want to use AWS EBS volumes for Kubernetes persistent volume. How can I use AWS EBS volumes within Kubernetes cluster for persistent volumes?
Cluster details:
kubectl veresion: 1.19
kubeadm veresion: 1.19

The official supported way to mount Amazon Elastic Block Store as Kubernetes volume on the self-managed Kubernetes cluster running on AWS is to use awsElasticBlockStorevolume type.
To manage the lifecycle of Amazon EBS volumes on the self-managed Kubernetes cluster running on AWS please install Amazon Elastic Block Store Container Storage Interface Driver.
We know that ECS runs containers so is it possible to transfer files between two ECS services in the same cluster?
I am using Fargate as launch type for my ECS instances
There are several approaches you use to solve this problem, however I would suggest utilising a shared NFS mount through the managed EFS service within both sets of containers.
AWS added support for EFS within Fargate containers for exactly this problem.
By utilising this all containers that have it configured in their task will be able to access the EFS file system as if it's a local volume.
More information is available in the Amazon EFS volumes documentation.
I am trying to mount a persistent storage in a Fargate container.
I have set up an EFS file system.
I have set up an ECS Cluster.
EFS and ECS share one subnet.
When I try to create a task definition, I choose Fargate and then on Add container. I scroll down to Storage and Logging and cannot choose the EFS file system in Mount points. I cannot choose anything here, the only choice I have is: <None>
This SO question suggests it is possible, but here it was answered using the AWS Cli Application. I wonder if I cannot just do it from the AWS Console (which is the web interface).
Before you can setup Mount point in your Container definition, you have to setup Volume in your Task definition:
I need to build a docker image and send it to an ECS repository.
Because my company's internet access is quite poor, I'm using an EC2 to achieve this.
I call docker push on the EC2, so I believe it may work similar as it is mentionned here with the cli.
My question is : As I am on the same AWS account and region, is my image transfer using docker push considered an external or an internal transfer ?
This has an impact on both speed and pricing.
I assume you mean building a docker image on a EC2 and then pushing to ECR. After this the ECS cluster will pull the image and run as a container?
In this case, see this relevant ECR FAQ question from https://aws.amazon.com/ecr/faqs/
Q: Is Amazon ECR a global service? Amazon ECR is a regional service
and is designed to give you flexibility in how images are deployed.
You have the ability to push/pull images to the same region where your
Docker cluster runs for the best performance. You can also access
Amazon ECR anywhere that Docker runs such as desktops and on-premises
environments. Pulling images between regions or out to the internet
will have additional latency and data transfer costs.
assuming that the EC2 with the cli on it and the EC2 with the ECS servers running on them are in the same zone and account then there is no charge
Remember that ECS is simply running on EC2..see the ECS FAQ
Amazon Elastic Container Service (ECS) is a highly scalable, high
performance container management service that supports Docker
containers and allows you to easily run applications on a managed
cluster of Amazon EC2 instances
If they are in a different zone then there is a charge, even in the same account
See https://aws.amazon.com/govcloud-us/pricing/data-transfer/
I think you are referring to Amazon's Elastic Container Registry (ECR).
Th ECR pricing page indicates that "Data transferred between Amazon Elastic Container Registry and Amazon EC2 within a single region is free of charge".
