ecspresso

ecspresso is a deployment tool for Amazon ECS.

(pronounced same as "espresso")

Usage

$ ecspresso
  -cluster string
    	ECS cluster name(required)
  -service string
    	ECS service name(required)
  -task-definition string
    	task definition path(required)
  -timeout int
    	timeout (sec) (default 300)

ecspresso works as below.

  • Register a new task definition from JSON file.
    • JSON file is same format as aws ecs describe-task-definition output.
    • Replace {{ env "FOO" "bar" }} syntax in the JSON file to environment variable "FOO".
      • If "FOO" is not defined, replaced by "bar"
    • Replace {{ must_env "FOO" }} syntax in the JSON file to environment variable "FOO".
      • If "FOO" is not defined, abort immediately.
  • Update a service definition.
  • Wait a service stable.
