nib-integrate

This nib plugin is designed to enable quick up and down of services that rely on one another to work correctly. This gem will rely on a common network having already been defined and the docker-compose.yml file or another integration yml file putting the containers in the right network.

Add this line to your application's Gemfile:

gem 'nib-integrate'

And then execute:

$ bundle

Or install it yourself as:

$ gem install nib-integrate

You must have nib version >= 2 in order for this plugin to work.

Once installed, you can begin using the plugin by typing:

nib integrate init

Initialization creates a .nib-integrate-config file in your home directory. The init step must be done before any of the other commands will work.

To register app1 from above for use with nib-integrate:

nib integrate register -a app1 -p /path/to/src/app1 -s web

To register external_service from above for use with nib-integrate:

nib integrate register -a external_service -p /path/to/src/external_service -s web

The external service's network configuration is in its docker-compose.yml file so you don't need to specify an integration file (-i) when registering the app

To bring both of these services up in the background and have them communicate together over the inter-service-network:

nib integrate up app1 external_service

To stop them both at the same time:

nib integrate down app1 external_service

To list registered services:

nib integrate list

When the up command is run, a dynamically generated integration file is generated. This file puts the service container in the default network and the nib-integrate-network. and provides an external link to all other registered services. This file is then passed as an additional configuration file to the docker-compose command that is generated when up is called.

# app1/docker-compose-integration.yml

services:
  web:
    external_links:
      - myexternalservice_web_1:myexternalservice_web
    networks:
      - default
      - outside
networks:
  outside:
    external:
      name: nib-integrate-network

Development is done using a docker environment. Run nib rspec gem to ensure specs are passing, and then changes can be made.
