ecs-solo

Deploy Docker image from ECS service to the current instance. This is useful if you want to deploy the current running ECS docker image onto an EC2 instance outside of ECS purview. It can also be useful to run the Docker container locally and exam it.

Usage

You may have to login to pull from the Docker regsitry first. Here's an example ECR login command:

eval $(aws ecr get-login --no-include-email --region us-west-2)

There are 2 forms that the ecs-solo deploy understands:

ecs-solo deploy STACK_NAME # CloudFormation template AWS::ECS::Service resource
ecs-solo deploy ECS_SERVICE --cluster development

• When passed the CloudFormation stack name, the ECS Cluster and Cluster is automatically infer. The cluster option is not needed and not used at all.
• When passed the ECS Service, the --cluster optional will probably be needed since the ECS service may not be running in the default development cluster.

Override command

You can override the default command in the Dockerfile with the -c option.

ecs-solo deploy demo-web-development -c bin/loop.sh

Example

Here's an example with output:

$ ecs-solo deploy demo-web-development
