FirstMile
----------
FirstMile is a cloud developer's sandbox. 

FirstMile simplifies the process of developing and deploying web applications to Amazon Elastic Beanstalk 
and Google App Engine (GAE). FirstMile is unique in that you don't need to make any changes to your application code 
in order to deploy it on Beanstalk or GAE. FirstMile supports testing your applications locally by deploying 
them in FirstMile's Docker-based sandbox. Additionally, FirstMile supports provisioning of relational database instances 
and their secure binding with your web applications.

Currently FirstMile supports Python Flask based web applications.


FirstMile has been tested on: Ubuntu 14.04, Ubuntu 16.04, Mac OS X (El Capitan, Darwin 15.4.0)


Completely scripted installation
---------------------------------
- Run ./install.sh


Manual installation 
------------------------
If completely scripted installation fails for some reason, you can do manual setup of FirstMile as follows:

Ubuntu:
-------
Open a terminal window and execute following:

$ ./setup-ubuntu.sh

$ source firstmile/bin/activate

$ python cld.py

Open another terminal window and execute following:

$ <cd to directory where you have cloned firstmile>

$ source firstmile/bin/activate

$ cld app list


Mac OS:
-------
Open a terminal window and execute following:

Install Docker for Mac

$ eval "$(docker-machine env default)"

  --> This command will enable this shell window to run Docker commands
      without sudo

$ ./setup-mac.sh

$ source firstmile/bin/activate

$ python cld.py

Open another terminal window and execute following:

$ <cd to directory where you have cloned firstmile>

$ source firstmile/bin/activate

$ cld app list

Deploying using YAML file
--------------------------
FirstMile supports YAML file for deployments.

The yaml file needs to be named 'cld.yaml' and it needs to be placed in the application directory.

cld.yaml allows providing of all the inputs to FirstMile CLI
in one step instead of using different command line flags.


Structure of YAML file:
-----------------------
The YAML file consists of three sections: application, services, cloud.
The cloud section is compulsory whereas application and services section
can be included depending on whether you want to deploy a service instance
or an application. Below is an example of YAML file containing all three sections.

+++++++++++++++++++++++++++++++++++++++
application:
  type: python
  entry_point: application.py
  env_variables:
    MY_VAR1: VALUE1
    MY_VAR2: VALUE2
services:
  - service:
      type: mysql
cloud:
  type: google
  project_id: greetings-python
  user_email: [email protected]
+++++++++++++++++++++++++++++++++++++++

Here are some examples of YAML file for different deployments.

1) Deploying MySQL service instance locally
--
services:
  - service:
      type: mysql
cloud:
  type: local-docker
--

2) Deploying Cloud SQL service instance on Google cloud
--
services:
  - service:
      type: mysql
cloud:
  type: google
  project_id: greetings-python
  user_email: [email protected]
--

3) Deploying RDS instance on AWS cloud
--
services:
  - service:
      type: mysql
cloud:
  type: aws
  SECRET_ACCESS_KEY: secret-access-key
  ACCESS_KEY_ID: access-key-id
--

4) Deploying application on Google cloud and using env_variables to 
   connect to an existing Cloud SQL instance:
--
application:
  type: python
  entry_point: application.py
  env_variables:
    DB: testdb
    HOST: 107.178.214.1
    USER: testuser
    PASSWORD: testpass123!@#
cloud:
  type: google
  project_id: greetings-python
  user_email: [email protected]
