ecs-run-task's Introduction

`ecs-run-task`

ecs-run-task is a cross-platform CLI tool to facilitate running ad-hoc tasks on the AWS EC2 Container Service (ECS).

Occasionally the need arises to run tasks in our infrastructure that are not long-running services. Examples include database migrations, batch jobs, ad-hoc database queries and general spelunking. To enable this use case, ECS exposes the RunTask functionality.

Usage

$ ecs-run-task run --help
Run a pre-defined ECS Task on a given cluster with possible
command override.

Usage:
  ecs-run-task run [flags]

Flags:
      --cluster string
      --command string
      --container string
      --task-definition string

Global Flags:
      --config string    config file (default is $HOME/.ecs-run-task.yaml)
      --profile string   profile defined in ~/.aws/config

ecs-run-task's Issues

Show logs _while_ task is running, not at end

CI + releases

Error handling

ECS can report back when the agent cannot run an image, e.g. image doesn't exist, couldn't find an instance and so on. We should check and report this back to the user.

Support creating tasks on-demand

Actually return correct exit code

Deal with lack of awslogs-stream-prefix

Rate limit to fix ThrottlingExceptions

I'm getting ThrottlingException errors when running this on an EC2 instance. I'm not sure which API is being throttled. I think it might be when polling the logs.

> ecs-run-task run --cluster dev --task-definition bash --container bash --command "ping -c 5 8.8.8.8"

Should we implement some form of exponential backoff as described here: https://aws.amazon.com/blogs/ses/how-to-handle-a-throttling-maximum-sending-rate-exceeded-error
