1 - Architecture

1.1 - Micro Service Framework

Cloudforet Architecture

The Cloudforet consists of a micro service architecture based on identity and inventory. Each micro services provides a plugin interface for flexibility of implementation.

Cloudforet Backend Software Framework

The Cloudforet development team has created our own S/W framework like Python Django or Java Spring. Cloudforet S/W Framework provides software framework for implementing business logic. Each business logic can present its services in various way like gRPC interface, REST interface or periodic task.

Backend Server Type

Based on Interface type, each micro service works as

1.2 - Micro Service Deployment

Cloudforet Deployment

The Cloudforet can be deployed by Helm chart. Each micro services has its own Helm chart, and the top chart, spaceone/spaceone contains all sub charts like console, identity, inventory and plugin.

Cloudforet provides own Helm chart repository. The repository URL is https://cloudforet-io.github.io/charts

helm repo add spaceone https://cloudforet-io.github.io/charts
helm repo list
helm repo update

helm search repo -r spaceone

See https://cloudforet.io/docs/setup_operation/

Helm Chart Code

Each repository should provide its own helm chart.

The code should be at {repository}/deploy/helm

Every Helm charts consists of four components.

The directory looks like

deploy
└── helm
    ├── Chart.yaml
    ├── config
    │   └── config.yaml
    ├── templates
    │   ├── NOTES.txt
    │   ├── _helpers.tpl

3 directories, 21 files

Based on micro service types like frontend, backend, or supervisor, the contents of templates directory is different.

Since every backend services has same templates files, spaceone provides sample of templates directory.
Template Sample URL:
https://github.com/cloudforet-io/spaceone/tree/master/helm_templates

Implementation

values.yaml

values.yaml file defines default vault of templates.

Application Configuration

Each server type like gRPC, rest, scheduler or worker server has its own specific configuration.

application_grpc: {}
application_rest: {}
application_scheduler: {}
application_worker: {}

This section is used at templates/application-{server type}-conf.yaml, then saved as ConfigMap.

Deployment file uses this ConfigMap at volumes,

then volumeMount as /opt/spaceone/{ service name }/config/application.yaml

So you can easily configure by adding configuration at application_scheduler like

application_scheduler:
    QUEUES:
        collector_q:
            backend: spaceone.core.queue.redis_queue.RedisQueue
            host: redis
            port: 6379
            channel: collector

    SCHEDULERS:
        hourly_scheduler:
            backend: spaceone.inventory.scheduler.inventory_scheduler.InventoryHourlyScheduler
            queue: collector_q
            interval: 1
            minute: ':00'

Local sidecar

If you want to append specific sidecar in this micro service.

# local sidecar
##########################
#sidecar:

Local volumes

Every micro service needs default timezone and log directory.

##########################
# Local volumes
##########################
volumes:
    - name: timezone
      hostPath:
          path: /usr/share/zoneinfo/Asia/Seoul
    - name: log-volume
      emptyDir: {}

Global variables

Every micro services need some part of same configuration or same sidecar.

#######################
# global variable
#######################
global:
    shared: {}
    sidecar: []

Service

gRPC or rest server needs Service

# Service
service:
    grpc:
        type: ClusterIP
        annotations:
            nil: nil
        ports:
            - name: grpc
              port: 50051

              port: 80
              targetPort: 80
              protocol: TCP

volumeMounts

Some micro service may need additional file or configuration. In this case use volumeMounts which can attach any thing.

################################
# volumeMount per deployment
################################
volumeMounts:
    application_grpc: []
    application_rest: []
    application_scheduler: []
    application_worker: []

POD Spec

We can configure specific value for POD spec. For example, we can use nodeSelector for deploy POD at specific K8S worker node.

####################################
# pod spec (append more pod spec)
# example nodeSelect
#
# pod:
#   spec:
#     nodeSelector:
#       application: my-node-group
####################################
pod:
    spec: {}

CI (github action)

If you want to make helm chart for this micro service, trigger at github action Make Helm Chart.

We don't need to make helm chart for each micro service usually,
since spaceone/spaceone top chart do all these steps.

4 - Design System

Overview

In the hyper-competitive software market, design system have become a big part of a product’s success. So, we built our design system based on the principles below.

A design system increases collaboration and accelerates design and development cycles. Also, a design system is a single source of truth that helps us speak with one voice and vary our tone depending on the situational context.

Principle

User-centered

Design is the “touch point” for users to communicate with the product. Communication between a user and a product is the key activity for us. We prioritize accessibility, simplicity, and perceivability. We are enabling familiar interactions that make complex products simple and straightforward for users to use.

Clarity

Users need to accomplish their complex tasks on our multi-cloud platform. We reduced the length of the thinking process by eliminating confusion for a better user experience. We aim to users achieve tasks simpler and improve motivation to solve tasks.

Consistency

Language development is supported by a variety of sensory experiences. We aim to have the best and the most perfectly consistent design system and keep improving the design system by checking usability.

6.1 - About Plugin

About Plugin

A plugin is a software add-on that is installed on a program, enhancing its capabilities.
The Plugin interface pattern consists of two types of architecture components: a core system and plug-in modules. Application logic is divided between independent plug-in modules and the basic core system, providing extensibility, flexibility, and isolation of application features and custom processing logic

Why Cloudforet use a Plugin Interface

• Cloudforet wants to accommodate various clouds on one platform. : Multi-Cloud / Hybrid Cloud / Anything
  
• We want to be with Cloudforet not only in the cloud, but also in various IT solutions.
• We want to become a platform that can contain various infrastructure technologies.
• It is difficult to predict the future direction of technology, but we want to be a flexible platform that can coexist in any direction.

Integration Endpoints

6.2 - Developer Guide

Plugin can be developed in any language using Protobuf. This is because both Micro Service and Plugin communication use Protobuf by default. The basic structure is the same as the server development process using the gRPC interface.

When developing plugins, it is possible to develop in any language (all languages that gRPC interface can use), but If you use the Python Framework we provide, you can develop more easily. All of the currently provided plugins were developed based on the Python-based self-developed framework.

For the basic usage method for Framework, refer to the following.

The following are the development requirements to check basically when developing a plugin, and you can check the detailed step-by-step details on each page.

6.2.1 - Plugin Interface

First, check the interface between the plugin to be developed and the core service. The interface structure is different for each service. You can check the gRPC interface information about this in the API document. (SpaceONE API)

For example, suppose we are developing an Auth Plugin for authentication of Identity. At this time, if you check the interface information of the Auth Plugin, it is as follows. (SpaceONE API - Identity Auth)

In order to develop Identity Auth Plugin, a total of 4 API interfaces must be implemented. Of these, init and verify are intefaces that all plugins need equally, The rest depends on the characteristics of each plugin.

Among them, let's take a closer look at init and verify, which are required to be implemented in common.

1. init

Plugin initialization. In the case of Identity, when creating a domain, it is necessary to decide which authentication to use, and the related Auth Plugin is distributed. When deploying the first plugin (or updating the plugin version), after the plugin container is created, the Core service calls the init API to the plugin. At this time, the plugin returns metadata information required when the core service communicates with the plugin. Information on metadata is different for each Core service.

Below is an example of python code for init implementation of Google oAuth2 plugin. Metadata is returned as a return value, and at this time, various information required by identity is added and returned.

    @transaction
    @check_required(['options'])
    def init(self, params):
        """ verify options
        Args:
            params
              - options
        Returns:
            - metadata
        Raises:
            ERROR_NOT_FOUND:
        """
        
        manager = self.locator.get_manager('AuthManager')
        options = params['options']
        options['auth_type'] = 'keycloak'
        endpoints = manager.get_endpoint(options)
        capability= endpoints
        return {'metadata': capability}

2. verify

Check the plugin's normal operation. After the plugin is deployed, after the init API is called, it goes through a check procedure to see if the plugin is ready to run, and the API called at this time is verify. In the verify step, the procedure to check whether the plugin is ready to perform normal operation is checked.

Below is an example of python code for verify implementation of Google oAuth2 plugin. The verify action is performed through the value required for Google oAuth2 operation. The preparation stage for actual logic execution requires verification-level code for normal operation.

    def verify(self, options):
        # This is connection check for Google Authorization Server
        # URL: https://www.googleapis.com/oauth2/v4/token
        # After connection without param.
        # It should return 404
        r = requests.get(self.auth_server)
        if r.status_code == 404:
            return "ACTIVE"
        else:
            raise ERROR_NOT_FOUND(key='auth_server', value=self.auth_server)

6.2.2 - Plugin Register

If plugin development is completed, you need to prepare plugin distribution. Since all plugins of SpaceONE are distributed as containers, the plugin code that has been developed must be built as an image for container distribution. Container build is done after docker build using Dockerfile, The resulting Image is uploaded to an image repository such as Docker hub. At this time, the image storage is uploaded to the storage managed by the Repository service, which is a microservice of SpaceONE.

If you have uploaded an image to the repository, you need to register the image in the Repository service among Microservices. Registration API uses Repository.plugin.register. (SpaceONE API - (Repository) Plugin.Register)

The example below is the parameter content delivered when registering the Notification Protocol Plugin. The image value contains the address of the previously built image.

name: Slack Notification Protocol
service_type: notification.Protocol
image: pyengine/plugin-slack-notification-protocol_settings
capability:
  supported_schema:
  - slack_webhook
  data_type: SECRET
tags:
  description: Slack
  "spaceone:plugin_name": Slack
  icon: 'https://spaceone-custom-assets.s3.ap-northeast-2.amazonaws.com/console-assets/icons/slack.svg'
provider: slack
template: {}

In the case of image registration, directly use gRPC API or use spacectl because it is not yet supported in Web Console. After creating the yaml file as above, you can register the image with the spacectl command as shown below.

> spacectl exec register repository.Plugin -f plugin_slack_notification_protocol.yml

When the image is registered in the Repository, you can check it as follows.

> spacectl list repository.Plugin -p repository_id=<REPOSITORY_ID>  -c plugin_id,name
plugin_id                              | name
----------------------------------------+------------------------------------------
 plugin-aws-sns-monitoring-webhook      | AWS SNS Webhook
 plugin-amorepacific-monitoring-webhook | Amore Pacific Webhook
 plugin-email-notification-protocol_settings     | Email Notification Protocol
 plugin-grafana-monitoring-webhook      | Grafana Webhook
 plugin-keycloak-oidc                   | Keycloak OIDC Auth Plugin
 plugin-sms-notification-protocol_settings       | SMS Notification Protocol
 plugin-voicecall-notification-protocol_settings | Voicecall Notification Protocol
 plugin-slack-notification-protocol_settings     | Slack Notification Protocol
 plugin-telegram-notification-protocol_settings  | Telegram Notification Protocol

 Count: 9 / 9

Detailed usage of spacectl can be found on this page. Spacectl CLI Tool

6.2.3 - Plugin Deployment

To actually deploy and use the registered plugin, you need to deploy a pod in the Kubernetes environment based on the plugin image. At this time, plugin distribution is automatically performed in the service that wants to use the plugin.

For example, in the case of Notification, an object called Protocol is used to deliver the generated Alert to the user. At that time, Protocol.create action (Protocol.create) triggers installing Notification automatically.

The example below is an example of the Protocol.create command parameter for creating a Slack Protocol to send an alarm to Slack in Notification.

---
name: Slack Protocol
plugin_info:
  plugin_id: plugin-slack-notification-protocol_settings
  version: "1.0"
  options: {}
  schema: slack_webhook
tags:
  description: Slack Protocol

In plugin_id, put the ID value of the plugin registered in the Repository, In version, put the image tag information written when uploading the actual image to an image repository such as Dockerhub. If there are multiple tags in the image repository, the plugin is distributed with the image of the specified tag version.

In the above case, because the version was specified as "1.0" It is distributed as a "1.0" tag image among the tag information below.

In the case of the API, it takes some time to respond because it goes through the steps of creating and deploying a Service and a Pod in the Kubernetes environment. If you check the pod deployment in the actual Kubernetes environment, you can check it as follows.

> k get po
NAME                                                              READY   STATUS    RESTARTS   AGE
plugin-slack-notification-protocol_settings-zljrhvigwujiqfmn-bf6kgtqz   1/1     Running   0          1m

6.2.4 - Plugin Debugging

Using Pycharm

• 1. Open Projects and Dependencies
• 2. Configure Virtual Environment
• 3. Run Server
• 4. Test Code

1. Open projects and dependencies

First, open project Identity, python-core and api one by one.

• Click Open

• Select your project directory. In this example '~/source/cloudone/identity'

• Click File > Open , then select related project one by one. In this example '~/source/cloudone/python-core'

• Select New Window for an additional project. You might need to do several times if you have multiple projects. Ex) python-core and api

• Now we have 3 windows. Just close python-core and API projects.

• Once you open your project at least one time, you can attach them to each other. Let's do it on identity project. Do this again Open > select your anther project directory. In this example, python-core and API.

But this time, you can ATTACH it to Identity project.

You can attach a project as a module if it was imported at least once.

2. Configure Virtual Environment

• Add additional python interpreter

• Click virtual environment section

• Designate base interpreter as 'Python 3.8'(Python3 need to be installed previously)

• Then click 'OK'

• Return to 'Python interpreter > Interpreter Settings..'

• List of installed python package on virtual environment will be displayed

• Click '+' button, Then search & click 'Install Package' below

• 'spaceone-core'

• 'spaceone-api'

• 'spaceone-tester'

• Additional libraries are in 'pkg/pip_requirements.txt' in every repository. You also need to install them.

• Repeat above process or you can install through command line

$> pip3 install -r pip_requirements.txt

3. Run Server

• Set source root directory
• Right click on 'src' directory 'Mark Directory as > Resource Root'
• Set test server configuration
• Fill in test server configurations are as below, then click 'OK'

• You can run test server with 'play button' on the upper right side or the IDE

4. Execute Test Code

Every plugin repository has their own unit test case file in 'test/api' directory

• Right click on 'test_collector.py' file
• Click 'Run 'test_collector''

Some plugin needs credential to interface with other services. You need to make credential file and set them as environments before run

• Go to test server configuration > test_server > Edit Configurations

• Click Edit variables

• Add environment variable as below

Finally you can test run your server

• First, run test server locally

• Second, run unit test

This guide explains the new SpaceONE API specification which extends the spaceone-api.

git clone https://github.com/cloudforet-io/api.git

Create new API spec file

Create new API spec file for new micro service. The file location must be

proto/spaceone/api/<new service name>/<version>/<API spec file>

For example, the APIs for inventory service is defined at

proto
└── spaceone
    └── api
        ├── core
        │   └── v1
        │       ├── handler.proto
        │       ├── plugin.proto
        │       ├── query.proto
        │       └── server_info.proto
        ├── inventory
        │   ├── plugin
        │   │   └── collector.proto
        │   └── v1
        │       ├── cloud_service.proto
        │       ├── cloud_service_type.proto
        │       ├── collector.proto
        │       ├── job.proto
        │       ├── job_task.proto
        │       ├── region.proto
        │       ├── server.proto
        │       └── task_item.proto
        └── sample
            └── v1
                └── helloworld.proto

If you create new micro service called sample, create a directory proto/spaceone/api/sample/v1

Define API

After creating API spec file, update gRPC protobuf.

The content consists with two sections. + service + messages

service defines the RPC method and message defines the request and response data structure.

syntax = "proto3";

package spaceone.api.sample.v1;

// desc: The greeting service definition.
service HelloWorld {
  // desc: Sends a greeting
  rpc say_hello (HelloRequest) returns (HelloReply) {}
}

// desc: The request message containing the user's name.
message HelloRequest {
  // is_required: true
  string name = 1;
}

// desc: The response message containing the greetings
message HelloReply {
  string message = 1;
}

Build API spec to specific language.

Protobuf can not be used directly, it must be translated to target langauge like python or Go.

If you create new micro service directory, udpate Makefile Append directory name at TARGET

TARGET = core identity repository plugin secret inventory monitoring statistics config report sample

Currently API supports python output.

make python

The generated python output is located at dist/python directory.

Actions

Cloudforet has 100+ repositories, 70 of which are for applications and these repositories have github action workflows.

Because of that, it's very difficult to handle one by one when you need to update or run a workflow.

To solve this problem, we created Actions.

The diagram below shows the relationship between Actions and repositories.

What does actions actually do?

Actions is a control tower that manages and deploys github action workflows for Cloudforet's core services.
It can also bulk trigger these workflows when a new version of Cloudforet's core services needs to be released.

1. Manage and deploy github action workflows for Cloudforet's core services.

All workflows for Cloudforet's core services are managed and deployed in this repository.

We write the workflow according to our workflow policy and put it in the workflows directory of Actions.
Then these workflows can be deployed into the repository of Cloudforet's core services

Our devops engineers can modify workflows according to our policy and deploy them in batches using this feature.

The diagram below shows the process for this feature.

*) If you want to see the Actions script that appears in the diagram, see here.

2. trigger workflows when a new version of Cloudforet's core services needs to be released.

When a new version of Cloudforet's core services is released, we need to trigger the workflow of each repository.
To do this, we made workflow that can trigger workflows of each repository in Actions.

Create a new page

Go to the parent page of the page creation location. Then, click the 'Create child page' button at the bottom right.

or:
You can also fork from the repository and work locally.

Choosing a title and filename

Create a filename that uses the words in your title separated by underscore (_). For example, the topic with title Using Project Management has filename project_management.md.

Adding fields to the front matter

In your document, put fields in the front matter. The front matter is the YAML block that is between the triple-dashed lines at the top of the page. Here's an example:

---
title: "Project Management"
linkTitle: "Project Management"
weight: 10
date: 2021-06-10
description: >
  View overall status of each project and Navigate to detailed cloud resources.  
---

Description of front matter variables

If you want to see more details about front matter, click Front matter.

Write a document

Adding Table of Contents

When you add ## in the documentation, it makes a list of Table of Contents automatically.

Adding images

Create a directory for images named file_name_img in the same hierarchy as the document. For example, create project_management_img directory for project_management.md. Put images in the directory.

Style guide

Please refer to the style guide to write the document.

Opening a pull request

When you are ready to submit a pull request, commit your changes with new branch.
