How to specify/create a worker environment

[KidA001]

I'd like to create a work environment. i can do this in the AWS console, but how do I specify that the environment is a worker environment in the eb.yml ?

develop-worker:
  options:
    aws:autoscaling:launchconfiguration:
      InstanceType: t2.small
  # what options specify worker?

I believe the options value is tier: Worker

@tongboy are there AWS docs that correspond to the values I can add into eb.yml or are there restrictions on what I can enter?

For instance, the next question I have is I want to call this environment develop-worker but have it use the rails env develop

[JeremiahChurch]

Yeah - in general most of that can be found under http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/customize-containers.html

rails env is just an environment variable - easy to keep separated from the environment name

@tongboy thanks. Derp, I knew that was set by env variable 😬

This seems to be working so far, thank you.

develop-worker:
  Tier: Worker
  options:
    aws:autoscaling:launchconfiguration:
      InstanceType: t2.small

@tongboy false positive, the environment deployed with that config, but it's not a worker instance.

drat! I pulled it out of the eb_deployer test case - https://github.com/ThoughtWorksStudios/eb_deployer/blob/master/test/tier_setting_deploy_test.rb

I haven't personally spun up a worker tier yet to have a known good example - maybe someone else who has could chime in?

I'd expect it to be a lowercase tier - some of the AWS keys are case sensitive and others aren't (I don't know the rhyme or reason)
