Mentoring Service

CircleCI insights

develop

The Mentoring building block enables effective mentoring interactions between mentors and mentees. The capability aims to create a transparent eco-system to learn, connect, solve, and share within communities.MentorED is an open source mentoring application that facilitates peer learning and professional development by creating a community of mentors and mentees.

Setup Options

Elevate services can be setup in local using three methods:

Docker-Compose File (Easiest)

A. Docker-Compose

Expectation: Run all services simultaneously with a common Docker-Compose file.

Steps

1. Install Docker & Docker-Compose.

2. To create/start all containers:

   ELEVATE/mentoring$ docker-compose up
   

   You can pass .env file to docker images of elevate service by using the below command

   ELEVATE/mentoring$ mentoring_env=".env path" users_env=".env path" notification_env=".env path" scheduler=".env path"  docker-compose up
   
   

3. To remove all containers & networks:

       ```
       ELEVATE/mentoring$ docker-compose down
       ```
   
       Refer **Docker-Compose README** for more information.
   
       **Note:** It isn't always necessary to run **down** command. Existing containers and networks can be stopped gracefully by using **Ctrl + C** key combination.
   
       **Warning:** Do not use docker-compose in production.
   

Dockerized service with local dependencies(Intermediate)

B. Dockerized Service With Local Dependencies

Expectation: Run single docker containerized service with existing local (in host) or remote dependencies.

Local Dependencies Steps

1. Update dependency (Mongo v4.1.4, Kafka etc) IP addresses in .env with "host.docker.internal".

   Eg:

    #MongoDb Connectivity Url
    MONGODB_URL = mongodb://host.docker.internal:27017/elevate-mentoring
   
    #Kafka Host Server URL
    KAFKA_URL = host.docker.external:9092
   

2. Find host.docker.internal IP address and added it to mongod.conf file in host.

   Eg: If host.docker.internal is 172.17.0.1, mongod.conf:

   # network interfaces
   net:
       port: 27017
       bindIp: "127.0.0.1,172.17.0.1"
   

   Note: Steps to find host.docker.internal IP address & location of mongod.conf is operating system specific. Refer this for more information.

3. Build the docker image.

   /ELEVATE/mentoring$ docker build -t elevate/mentoring:1.0 .
   

4. Run the docker container.

   • For Mac & Windows with docker v18.03+:

     $ docker run --name mentoring elevate/mentoring:1.0
     

   • For Linux:

     $ docker run --name mentoring --add-host=host.docker.internal:host-gateway elevate/mentoring:1.0`
     

     Refer this for more information.

Remote Dependencies Steps

1. Update dependency (Mongo v4.1.4, Kafka etc) Ip addresses in .env with respective remote server IPs.

   Eg:

    #MongoDb Connectivity Url
    MONGODB_URL = mongodb://10.1.2.34:27017/elevate-mentoring
   
    #Kafka Host Server URL
    KAFKA_URL = 11.2.3.45:9092
   

2. Add Bind IP to mongod.conf in host:

   Follow the instructions given here.

   Note: Instructions might differ based on MongoDB version and operating system.

3. Build the docker image.

   /ELEVATE/mentoring$ docker build -t elevate/mentoring:1.0 .
   

4. Run the docker container.

   ```
   $ docker run --name mentoring elevate/mentoring:1.0
   ```
   

Local Service with local dependencies(Hardest)

C. Local Service With Local Dependencies

Expectation: Run a single service with existing local dependencies in the host (Non-Docker Implementation).

Steps

1. Install required tools & dependencies

   Install any IDE (eg: VScode)

   Install Nodejs: https://nodejs.org/en/download/

   Install MongoDB: https://docs.mongodb.com/manual/installation/

   Install Robo-3T: ​​ https://robomongo.org/

2. Clone the Mentoring service repository.

   git clone https://github.com/ELEVATE-Project/mentoring.git
   

3. Add .env file to the project directory

   Create a .env file in src directory of the project and copy these environment variables into it.

   # Mentoring Service Config
   
   # Port on which service runs
   APPLICATION_PORT = 3000
   
   # Service environment
   APPLICATION_ENV = development
   
   # Route after base url
   APPLICATION_BASE_URL = /mentoring/
   
   # Mongo db connectivity url
   MONGODB_URL = mongodb://localhost:27017/elevate-mentoring
   
   # Token secret to verify the access token
   ACCESS_TOKEN_SECRET = 'bsj82AHBxahusub12yexlashsbxAXADHBlaj'
   
   # Kafka hosted server url
   KAFKA_URL = localhost:9092
   
   # Kafka group to which consumer belongs
   KAFKA_GROUP_ID = userservice
   
   # Kafka topic to push notification data
   NOTIFICATION_KAFKA_TOPIC = notificationtopic
   
   # Kafka topic name to consume from mentoring topic
   KAFKA_MENTORING_TOPIC ="mentoringtopic"
   
   # Kafka topic to push recording data
   KAFKA_RECORDING_TOPIC ="recordingtopic"
   
   # Any one of three features available for cloud storage
   CLOUD_STORAGE = 'GCP/AWS/AZURE'
   
   # Gcp json config file path
   GCP_PATH = 'gcp.json'
   
   # Gcp bucket name which stores files
   DEFAULT_GCP_BUCKET_NAME = 'gcp-bucket-storage-name'
   
   # Gcp project id
   GCP_PROJECT_ID = 'project-id'
   
   # Aws access key id
   AWS_ACCESS_KEY_ID = 'aws-access-key-id'
   
   # Aws secret access key
   AWS_SECRET_ACCESS_KEY = 'aws-secret-access-key'
   
   # Aws region where bucket will be located
   AWS_BUCKET_REGION = 'ap-south-1'
   
   # Aws end point
   AWS_BUCKET_ENDPOINT = 's3.ap-south-1.amazonaws.com'

   AZURE_ACCOUNT_NAME = 'account-name'
   
   # Azure storage account key
   AZURE_ACCOUNT_KEY = 'azure-account-key'
   
   # Azure storage container which stores files
   DEFAULT_AZURE_CONTAINER_NAME = 'azure-container-storage-name'
   
   # user serice host
   USER_SERIVCE_HOST = 'http://localhost:3001'
   
   # user serice base url
   USER_SERIVCE_BASE_URL = '/user/'
   
   # Big blue button url
   BIG_BLUE_BUTTON_URL = https://dev.mentoring.shikshalokam.org
   
   # Big blue button base url
   BIB_BLUE_BUTTON_BASE_URL = /bigbluebutton/
   
   # Meeting end callback events end point
   MEETING_END_CALLBACK_EVENTS = https%3A%2F%2Fdev.elevate-apis.shikshalokam.org%2Fmentoring%2Fv1%2Fsessions%2Fcompleted
   
   # Big blue button secret key
   BIG_BLUE_BUTTON_SECRET_KEY = n
   
   # Big blue button recording ready callback url
   RECORDING_READY_CALLBACK_URL = http%3A%2F%2Flocalhost%3A3000%2F%3FmeetingID%3Dmeet123
   
   # Enable logging of network request
   ENABLE_LOG = true
   

4. Start MongoDB locally

   Based on your host operating system and method used, start MongoDB.

5. Install Npm packages

   ELEVATE/mentoring/src$ npm install
   

6. Start Mentoring server

   ELEVATE/mentoring/src$ npm start
   

7. To set scheduler service job

   Run the schedulerScript file from the scripts directory:

   ELEVATE/mentoring/src/scripts$ node schedulerScript.js

Migrations Commands

Check migrations

npm run elevate-migrations s

Create migrations

npm run elevate-migrations create categoryEntity #Where categoryEntity is the file name.

20220726145008-categoryEntity.js

We have followed the following structure for migration files to reduce code duplication.

let categories = [
	{
		value: 'sqaa',
		label: 'SQAA',
		image: 'entity/SQAA.jpg',
	},
	{
		value: 'communication',
		label: 'Communication',
		image: 'entity/Communication.png',
	},
    ...
]
var moment = require('moment')

module.exports = {
	async up(db) {
		global.migrationMsg = 'Uploaded categories entity'
		let entityData = []
		categories.forEach(async function (category) {
			category['status'] = 'ACTIVE'
			category['deleted'] = false
			category['type'] = 'categories'
			category['updatedAt'] = moment().format()
			category['createdAt'] = moment().format()
			category['createdBy'] = 'SYSTEM'
			category['updatedBy'] = 'SYSTEM'
			entityData.push(category)
		})
		await db.collection('entities').insertMany(entityData)
	},

	async down(db) {
		db.collection('entities').deleteMany({
			value: { $in: categories.map((category) => category.value) },
		})
	},
}
