Scheduler Service

CircleCI insights

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 scheduler services can be setup in local using two methods:

Dockerized service with local dependencies(Intermediate)

A. 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-scheduler
   
    #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/scheduler$ docker build -t elevate/scheduler:1.0 .
   

4. Run the docker container.

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

     $ docker run --name user elevate/scheduler:1.0
     

   • For Linux:

     $ docker run --name user --add-host=host.docker.internal:host-gateway elevate/scheduler: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-scheduler
   
    #Kafka Host Server URL
    KAFKA_URL = 11.2.3.45:9092
   

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

   Follow instructions given here.

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

3. Build the docker image.

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

4. Run the docker container.

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

Local Service with local dependencies(Hardest)

B. Local Service With Local Dependencies

Expectation: Run single service with existing local dependencies in 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 Scheduler service repository.

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

   #Scheduler Service Config
   
   #Application Base url
   APPLICATION_BASE_URL = /scheduler/
   
   # Kafka hosted server url
   KAFKA_URL = localhost:9092
   
   # Kafka topic to push notification data
   NOTIFICATION_KAFKA_TOPIC = 'notificationtopic'
   
   # MONGODB_URL
   MONGODB_URL = mongodb://localhost:27017/tl-cron-rest
   
   # App running port
   APPLICATION_PORT = 4000
   
   # Api doc url
   API_DOC_URL = '/api-doc'
   

4. Start MongoDB locally

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

5. Install Npm packages

   ELEVATE/scheduler/src$ npm install
   

6. Start Scheduler server

   ```
   ELEVATE/scheduler/src$ npm start
   ```
