ecs-cluster

Tools for working with AWS ECS clusters.

Installation

pip install git+https://github.com/silvercar/ecs-cluster

Usage

Updating the container image in a task definition

This will update the image in the task definition, and update the service to use this new definition. Afterwards, the ecs-agent will take care of starting new tasks and stopping the old ones (according to its deployment configuration/health check rules).

ecs-cluster update-image --cluster <cluster_name> --service <ecs_service_name> --container <ecs_container_name> --image <ecr_image>

SSHing into a container

ecs-cluster ssh-service --cluster cluster-name --service service-name --user username

Updating a task image and restarting the task

Same as above, except the tasks will be forcefully stopped first, and then replaced. Note the --restart flag.

ecs-cluster update-image --cluster <cluster_name> --service <ecs_service_name> --container <ecs_container_name> --image <ecr_image> --restart
