ecsgo

Inspired by the incredibly useful gossm, this tool makes use of the 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. You can also use it to port-forward to containers within your tasks.

That's it! Nothing fancy.

Usage

CLI Args

By default, the tool will prompt you to interactively select which cluster, service, task and container to connect to. You can change the behaviour using the flags detailed below:

Long	Short	Description	Default Value
`--cluster`	`-n`	Specify the ECS cluster name	N/A
`--service`	`-s`	Specify the ECS service name	N/A
`--task`	`-t`	Specify the ECS Task ID	N/A
`--container`	`-u`	Specify the container name in the ECS Task (if task only has one container this will selected by default)	N/A
`--cmd`	`-c`	Specify the command to be run on the container (default will change depending on OS family).	`/bin/sh`,`powershell.exe`
`--forward`	`-f`	Port-forward to the container (Remote port will be taken from task/container definitions)	`false`
`--local-port`	`-l`	Specify local port to forward (will prompt if not specified)	N/A
`--profile`	`-p`	Specify the profile to load the credentials	`default`
`--region`	`-r`	Specify the AWS region to run in	N/A
`--quiet`	`-q`	Disable output detailing the Cluster/Service/Task information	`false`
`--aws-endpoint-url`	`-e`	Specify the AWS endpoint used for all service requests	N/A

Environment variables

The above options can also be configured via environment variables. Simply export environment variables in the form ECSGO_<OPT_NAME>. For example, if you want to set the --cluster value, it would be ECSGO_CLUSTER, or for the --aws-endpoint-url option it would be ECSGO_AWS_ENDPOINT_URL.

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