#ecs-deploy Deploy container images to Amazon EC2 Container Service (ECS).
Applications running inside the container will have access to an environment variable named IMAGE_TAG which will contain the tag of the image used to build that container.
In order to communicate with AWS, the aws-sdk library needs to be configured with your authentication credentials and, possibly, with the aws region you wish to target. More information can be found here. If you already use the aws cli then you're likely already configured.
In order to deploy your container, you need to provide this tool with some information in the form of environment variables:
| Variable Name | Description |
|---|---|
| CLUSTER | The name of the target ECS cluster |
| SERVICE | The name of the target ECS service |
| CONTAINER | The name of the target ECS container |
| IMAGE | The image repository (e.g. example_org/example_app) |
| IMAGE_TAG | The tag of the target container image |
Install from the command line:
npm install --save-dev ecs-deployAdd a deploy script to your package.json:
{
"scripts": {
"deploy": "CLUSTER=my_cluster SERVICE=my_service CONTAINER=my_container IMAGE=my_user/my_repo ecs-deploy"
}
}When you're ready to deploy, make sure your image has been pushed to the registry. Then from the command line:
IMAGE_TAG=latest npm run deploy
