Using client
============


Building sandboxes
------------------

Sandboxes in qubell platform could be created on different levels. Maximum isolated sandbox could be achieved by separate organization (with it's own environments, users and application).

Simple way to create sandbox (see ./contrib-python-qubell-client/sandbox/):
Create file containing organization structure, for example:


organizations:
- name: DEFAULT_ORG
applications:
- name: super_parent
file: ./super_parent.yml
- name: middle_child
file: ./middle_child.yml
- name: child
file: ./child.yml

environments:
- name: default
services:
- name: Default credentials service
- name: Default workflow service
- name: child-service

services:
- name: Default workflow service
type: builtin:workflow_service
- name: Default credentials service
type: builtin:cobalt_secure_store
- name: child-service
application: child

instances:
- name: test-instance
application: super_parent


Now you can create organization, running:

./restore_env.py default.env


After, you will have fully configured organization, even with running instances. This example shows how to describe 3-level hearchical application, where child instance launched as service.



Coding your own scripts
-----------------------

First way of creating sandbox, using restore method:

config = {'organizations': [{'name': 'DEFAULT_ORG',
'applications': [{'file': './super_parent.yml',
'name': 'super_parent'},
{'file': './middle_child.yml',
'name': 'middle_child'},
{'file': './child.yml',
'name': 'child'}],
'environments': [{'name': 'default',
'services': [{'name': 'Default credentials service'},
{'name': 'Default workflow service'},
{'name': 'child-service'}]}],
'instances': [{'application': 'super_parent',
'name': 'test-instance'}],
'providers': [{'ec2SecurityGroup': 'default',
'jcloudsCredential': 'AAAAAAAAA',
'jcloudsIdentity': 'BBBBBBBBBBB',
'jcloudsRegions': 'us-east-1',
'name': 'generated-provider-for-tests',
'provider': 'aws-ec2',
'providerCopy': 'aws-ec2'}],
'services': [{'name': 'Default workflow service',
'type': 'builtin:workflow_service'},
{'name': 'Default credentials service',
'type': 'builtin:cobalt_secure_store'},
{'application': 'child',
'name': 'child-service'}]}]}


from qubell.api.private.platform import QubellPlatform
from qubell.api.globals import QUBELL

platform = QubellPlatform.connect(user=QUBELL['user'], password=QUBELL['password'], tenant=QUBELL['tenant'])
platform.restore(config)

# Let's check what we've got
print platform.organizations['DEFAULT_ORG'].name
for ins in platform.organizations['DEFAULT_ORG'].instances:
print ins.name


Second way, using get/create methods:

from qubell.api.private.platform import QubellPlatform
from qubell.api.private.manifest import Manifest
from qubell.api.globals import QUBELL, PROVIDER_CONFIG, DEFAULT_WORKFLOW_SERVICE, DEFAULT_CREDENTIAL_SERVICE, DEFAULT_CLOUD_ACCOUNT_SERVICE
from qubell.api.private.service import CLOUD_ACCOUNT_TYPE, WORKFLOW_SERVICE_TYPE, COBALT_SECURE_STORE_TYPE

# Connect to platform
platform = QubellPlatform.connect(user=QUBELL['user'], password=QUBELL['password'], tenant=QUBELL['tenant'])

##### Organization
org = platform.organization(name='DEFAULT_ORG')
# After executing this code, organization "DEFAULT_ORG" would be created (if not exists) or initialized (if exists)

##### Environment

# Usually environment consists of cloud account, keystore service and workflow service. So, we need to add these services to our organization, then add them to our environment:

def prepare_env(org):

# Add services to organization
key_service = org.service(type=COBALT_SECURE_STORE_TYPE, name=DEFAULT_CREDENTIAL_SERVICE())
wf_service = org.service(type=WORKFLOW_SERVICE_TYPE, name=DEFAULT_WORKFLOW_SERVICE())
cloud_account = org.service(type=CLOUD_ACCOUNT_TYPE, name=DEFAULT_CLOUD_ACCOUNT_SERVICE(), parameters=PROVIDER_CONFIG)

# Add services to environment
env = org.environment(name='new-environment')
env.clean()
env.add_service(key_service)
env.add_service(wf_service)
env.add_service(cloud_account)

# Here we regenerate keypair
env.add_policy(
{"action": "provisionVms",
"parameter": "publicKeyId",
"value": key_service.regenerate()['id']})
return env

environment = prepare_env(org)

# Now, platform ready to be used. We need only application with valid manifest.

##### Application
# We need manifest to create application::

manifest = Manifest(url='https://raw.githubusercontent.com/qubell/contrib-python-qubell-client/master/sandbox/child.yml')

# Creating application
app = org.application(manifest=manifest, name='first_app')

# Application will be created.
# Let's start instance using in env1 :

instance = org.create_instance(application=app, environment=environment)

# This way we wait instance to came up in 15 minutes or break.
assert instance.ready(15)
print instance.return_values['child_out.child_output']
