SMTP Configuration Service

This service configures SMTP settings for Wild Cloud applications to send transactional emails.

Overview

The SMTP service doesn't deploy any Kubernetes resources. Instead, it helps configure global SMTP settings that can be used by Wild Cloud applications like Ghost, Gitea, and others for sending:

Password reset emails
User invitation emails
Notification emails
Other transactional emails

Installation

./setup/cluster-services/smtp/install.sh

Configuration

The setup script will prompt for:

SMTP Host: Your email provider's SMTP server (e.g., email-smtp.us-east-2.amazonaws.com for AWS SES)
SMTP Port: Usually 465 for SSL or 587 for STARTTLS
SMTP User: Username or access key for authentication
From Address: Default sender email address
SMTP Password: Your password, secret key, or API key (entered securely)

Supported Providers

AWS SES: Use your Access Key ID as user and Secret Access Key as password
Gmail/Google Workspace: Use your email as user and an App Password as password
SendGrid: Use apikey as user and your API key as password
Mailgun: Use your Mailgun username and password
Other SMTP providers: Use your standard SMTP credentials

Applications That Use SMTP

Ghost: User management, password resets, notifications
Gitea: User registration, password resets, notifications
OpenProject: User invitations, notifications
Future applications: Any app that needs to send emails

Testing

After configuration, test SMTP by:

Deploying an application that uses email (like Ghost)
Using password reset or user invitation features
Checking application logs for SMTP connection issues
