Sending E-mails

Environment Variables

MAIL_URL: The server reads from the MAIL_URL environment variable to determine how to send mail. The MAIL_URL should reference an SMTP server and use the form:

smtp://USERNAME:PASSWORD@HOST:PORT

or

smtps://USERNAME:PASSWORD@HOST:PORT

The smtps:// form (the s is for “secure”) should be used if the mail server requires TLS/SSL (and does not use STARTTLS) and is most common on port 465. Connections which start unencrypted prior to being upgraded to TLS/SSL (using STARTTLS) typically use port 587 (and sometimes 25) and should use smtp://. For more information see the Nodemailer docs

Docker Setup

The MAIL_URL can be passed to Docker with the -e parameter:

docker run --name titra -p 3000:3000 --link mongodb -e MONGO_URL=mongodb://mongodb/titra -e ROOT_URL=http://localhost:3000 -e MAIL_URL=smtp://USERNAME:PASSWORD@HOST:PORT kromit/titra

It can also be added in a similar way with docker-compose:

version: '3'
services:
  titra:
    image: kromit/titra
    container_name: titra_app
    depends_on:
      - mongodb
    environment:
      - ROOT_URL=${ROOT_URL}
      - MONGO_URL=mongodb://mongodb/titra?directConnection=true
      - PORT=3000
      - MAIL_RUL=MAIL_URL=smtp://USERNAME:PASSWORD@HOST:PORT
    ports:
      - "3000:3000"
    restart: always
  mongodb:
    image: mongo:5.0
    container_name: titra_db
    restart: always
    environment:
      - MONGO_DB:titra
    volumes:
      - titra_db_volume:/data/db
volumes:
  titra_db_volume:
