development: Commands CLI

[armand1m]

Proposal

Create a CLI for handling the microservices environment state

Why we need this

To create this environment, you need to:

• Create a directory.
• cd directory
• git init
• git submodule add https://github.com/armand1m/microservices-compose-utils ./commands
• git submodule add https://github.com/armand1m/core-services.
• Create a docker-compose.yml file with this content:

version: '2'
services:
  consul:
    extends:
      file: ./core-services/services.yml
      service: consul_service

  gateway:
    extends:
      file: ./core-services/services.yml
      service: fabio_service
    links:
      - consul

To add a service to the recently created environment, you need to:

• git clone https://github.com/armand1m/microservice-barebone ./my-service
• cd ./my-service
• git submodule add https://github.com/<user>/<service-name>
• Edit the docker-compose.yml to extend and run the added service. Let's say you are adding armand1m/bucket-service. The file would look like this after the modifications:

  service:
    extends:
      file: ./bucket-service/service.yml
      service: service
    volumes:
      - ./data:/data
    depends_on:
      - consul
    links:
      - consul

  consul:
    extends:
      file: ./core-services/services.yml
      service: consul_service

  gateway:
    extends:
      file: ./core-services/services.yml
      service: fabio_service
    links:
      - consul
