Buddy, your Cloudformation/ECS valet

Opinionated tools to manage your AWS infrastructure.

Manage your cloudformation stacks

Cloudformation stacks are described by stack files

• YAML format

• Specify which Cloudformation template to use

• Specify the parameters to use when creating/updating stacks

Examples:

$ bstack list
...

$ cat .aws/production.yaml
name: helloworld
template: service.yaml

$ cat service.yaml
AWSTemplateFormatVersion: 2010-09-09
Description: Handle Service
Resources:
...

$ bstack create .aws/production.yaml
$ bstack events helloworld  # or bstack events .aws/production.yaml
$ bstack resources helloworld
$ bstack update .aws/production.yaml
$ bstack delete helloworld

Manage your services and tasks on ECS

Alpha: in development. Currently only implement deploy action for continuous deployment on ECS.

$ cat .aws/cluster.yaml

  production:
    cluster: production
    service: service-Service-1234567890JVM
    task: helloworld
    environment: production

      portMappings:
        - containerPort: 80
          hostPort: 0  # 0 = dynamic port
      links: ['app']
      command: ['nginx', '-g', 'daemon off;']
  app:
    properties:
      memory: 200

      command: ['celery', '-A', 'helloworld', 'worker', '-B', '-l', 'info']
