ecspresso Advent Calendar 2020 Day 15 - create

This is Day 15 of the ecspresso Advent calendar, which summarizes how to use ecspresso, a deployment tool for Amazon ECS.

create command to create an ECS service

ecspresso create registers a task definition and creates a new ECS service that uses that task definition.

Options for the create command

usage: ecspresso create [<flags>]

create service

Flags:
  --help           Show context-sensitive help (also try --help-long and --help-man).
  --config=CONFIG  config file
  --debug          enable debug log
  --color          enalble colored output
  --dry-run        dry-run
  --tasks=-1       desired count of tasks
  --no-wait        exit ecspresso immediately after just created without waiting for service stable

--tasks

Specifies the number of tasks to run at the time the service is created.

The number of tasks is determined in the following order of priority, similar to the deploy command.

1. The value of --tasks specified as an option
2. The value of desiredCount existing in the service definition
   This value is also applied to the service during deployment. If you want to control the number of tasks externally by setting up auto-scaling, etc., please delete the desiredCount item altogether.

--no-wait

Exits immediately after creating the service without waiting for the tasks to start.

Day 16 will explain how to delete an ECS service.
