ecs-shell 0.0.1.dev14

Interactive shell for AWS ECS tasks with service and task selection.

ecs-shell

ecs-shell is yet another interactive CLI tool for connecting to AWS ECS (Elastic Container Service) tasks. It provides a user-friendly interface to browse services, select tasks, and establish shell sessions - all without having to remember complex AWS CLI commands or task IDs.

I have created this as an utility for me in the past, and only later found that there are plenty of others out there. I think the CLI UX with this one is better, so I decided to publish it anyways.

📋 Requirements

Before using ecs-shell, ensure you have the following installed and configured:

1. AWS CLI

The AWS CLI must be installed and authenticated with appropriate permissions.

aws configure

Required AWS Permissions:

• ecs:ListServices
• ecs:ListTasks
• ecs:DescribeTasks
• ecs:ExecuteCommand

2. Session Manager Plugin

The Session Manager plugin is required for establishing interactive sessions with ECS tasks.

# Install Session Manager plugin (macOS)
brew install --cask session-manager-plugin

For other operating systems, see the AWS Session Manager Plugin installation guide.

3. Python

Python 3.10 or higher is required.
