E1S - Easily Manage AWS ECS Resources in Terminal 🐱

e1s is a terminal application to easily browse and manage AWS ECS resources, supports both Fargate and EC2 ECS launch types. Inspired by k9s.

A quick video demo

AWS credentials and configuration

e1s uses the default aws-cli configuration. It does not store or send your access and secret key anywhere. The access and secret key are used only to securely connect to AWS API via AWS SDK. Both profile and region are overridable via the AWS_PROFILE, AWS_REGION prepend environment variable or --profile, --region option.

Installation

e1s is available on Linux, macOS and Windows platforms.

• Binaries for Linux, Windows and Mac are available in the release page.
• Homebrew for maxOS or Linux
• Docker image

brew install keidarcy/tap/e1s
# brew upgrade
# brew upgrade keidarcy/tap/e1s
# docker image
# docker pull ghcr.io/keidarcy/e1s:latest

Usage

Make sure you have the AWS CLI installed and properly configured with the necessary permissions to access your ECS resources, and session manager plugin installed if you want to use the interactive exec or port forwarding features.

Interactively exec towards containers(ECS Exec)

Use aws-ecs-exec-checker to check for the pre-requisites to use ECS exec.

interactive exec demo

Use ctrl + d to exit interactive-exec session.

Troubleshooting

The execute command failed because execute command... - check service execute command, task role policy

Session Manager plugin not found - document.

Update service

Register task definition

Start port forwarding session

With a specified task and container, to start port forwarding session you need to specify a port and a local port. The local port is the port on your local machine that you want to use to access the container port.

Port forwarding session

Start remote host port forwarding session

With a specified task and container, to start a remote host port forwarding session you need to specify a port, a host and a local port. The local port is the port on your local machine that you want to use to access the remote host port though container.

Remote host port forwarding session

File transfer

Implemented by a S3 bucket. Since file transfer though a S3 bucket and aws-cli in container, you need a S3 bucket and add permissions S3 bucket permission to the task role and e1s role, and also need a aws-cli installed container.
