ecsgo

Heavily inspired by incredibly useful gossm, this tool makes use of the new ECS ExecuteCommand API to connect to running ECS tasks. It provides an interactive prompt to select your cluster, task and container (if only one container in the task it will default to this), and opens a connection to it.

That's it! Nothing fancy.

Infrastructure

You'll need to follow the prerequisites for ECS Exec as outlined in the blog post.

You can also view some additional documentation on using ECS Exec here.

Usage

Flag	Description	Default Value

The tool also supports AWS Config/Environment Variables for configuration. If you aren't familiar with working on AWS via the CLI, you can read more about how to configure your environment here.

Why would I use this over something like AWS Copilot?

At this moment in time copilot only supports connecting to resources that are created and/or managed by the copilot CLI. This tool allows you to leverage ECS Exec easily with your existing resources, and plugs the gap until you are able to do the same with Copilot.
