A Node.js (Typescript) app to check for new subdomains and notify if found any

• Installation
  • Cloning
  • Configuration
  • Writing docker-compose.yml
  • Running subnode

To be able to install SubNode you need Docker, Docker Compose and Git installed.

First clone this repository using this command:

git clone https://github.com/aigic8/subnode

Alongside subnode dir, create a directory called config and inside that create a dir called subnode. Copy and rename subnode.sample.json to subnode dir and call it subnode.json using this command:

mkdir -p config/subnode
cp subnode/subnode.sample.json config/subnode/subnode.json

Your tree should look like this:

subnode/
  Dockerfile
  subnode.sample.json
  src/
  ...
config/
  subnode/
    subnode.json

Then edit config/subnode/subnode.json based on your needs.

Create a file named docker-compose.yml alongside subnode and config dirs. Write this content in it:

version: "3.9"
  subnode:
    build: ./subnode
    restart: always
    ports:
      - 8080:8080 # change the port based on your need
    links:
      - mongodb:mongodb # the hostname of db, should be used in config file
    volumes:
      - ./config/subnode:/usr/src/app/config
    environment:
      - CONFIG_PATH=/usr/src/app/config/subnode.json
    container_name: subnode
  mongodb:
    image: mongo:latest
    restart: always
    ports:
      - "127.0.0.1:27017:27017"
    container_name: mongodb

Now you can easily run the application using this command:

docker compose up -d mongodb
docker compose up -d subnode
