emailpub

emailpub is a Google Cloud Platform Cloud Function. It gets triggered by messages published to a Pub/Sub topic. Each message represents an email to send.

It sends email via SMTP. The Pub/Sub messages include the subject, recipient, and text body.

I created it because I wanted to send emails from hosts where I don't want to expose SMTP credentials. With emailpub, I can give these hosts a GCP service account allowing them to publish messages to send emails.

Setup

Create env.yml:

---
SMTP_HOST: smtp.gmail.com
SMTP_PORT: '587'
SMTP_USER: ...@gmail.com
SMTP_PASS: password...

Deploy the function (also creates the Pub/Sub topic):

gcloud functions deploy EmailPub \
  --runtime go113 \
    --trigger-topic emailpub \
    --source . \
    --env-vars-file env.yml
