How to Dynamically Retrieve CloudWatch Log Links for an ECS Fargate Task?

DevOps AWS
#1

I have a task that runs on ECS fargate. That task generate logs on cloudwatch when it starts running. Is there a way to make my script lookup the log link from cloudwatch for it’s own task?

Pull the arn from the metadata endpoint. Then you should know how to call the logs.

How can I access these Task metadata endpoint information? The documentation says ${ECS_CONTAINER_METADATA_URI_V4}/task/stats. What’s that?

Checking this other doc page: https://docs.aws.amazon.com/AmazonECS/latest/developerguide/task-metadata-endpoint.html

#5

it says that the endpoint is a url, pointing to an ip… but that’s for ECS on EC2…

#6

what about ecs fargate?

#7

This documentation for ecs fargate (https://docs.aws.amazon.com/AmazonECS/latest/userguide/task-metadata-endpoint-v4-fargate.html) does not mention any url.

nevermind, I was able to make it work… that’s actually already the endpoint…
