You can get Contexto to connect via SSH to a Bash shell, or a Rails console. If you're using SSH you'll need to add a key allowing access to the specific ECS hosts. This is usually the key used when you created the cluster.

You can also specify a cluster and service to take a shortcut to a specific set of containers.

$ contexto -c production -s backend-app
