Installation

1. clone the repo

git clone https://github.com/TRudenko22/caster
cd caster

2. build the docker image

docker build -t caster .

3. run the docker image

docker run -p 8080:9000 -p 587:587 -e EMAIL_PASSWORD=<your gmail app password> caster

Usage

The docker image has the two default environment variables set:

EMAIL_SERVER  = smtp.gmail.com
EMAIL_PORT    = 587

These can be changed by passing them in the docker run command and publishing their respective ports

docker run -p 8080:9000 -p <EMAIL_PORT>:<EMAIL_PORT> -e EMAIL_SERVER=<your email server> -e EMAIL_PORT=<your email port> -e EMAIL_PASSWORD=<your gmail app password> caster

Additionally you can use the provided docker-compose.yml as a template for your own deployment.

The API has two endpoints: / - GET - returns a simple message for testing /send - POST - sends an email

The /send endpoint requires a JSON body with the following fields:

{
    "sender": <your email address>,
    "recipients": [<list of email addresses>],
    "subject": <email subject>,
    "body": <email body>
}

Roadmap

• more robust body parsing
• better error handling
• more email providers
• client application in Go
