What is Sendy?

Sendy is a self-hosted email newsletter application that lets you send trackable emails via Amazon Simple Email Service (SES). This makes it possible for you to send authenticated bulk emails at an insanely low price without sacrificing deliverability.

For more information and related downloads for Sendy Server and other products, please visit Send.co.

How to use this image

Starting a Sendy instance is simple.

$ docker run -d \
  --name sendy \
  -e SENDY_FQDN=campaigns.example.com \
  -e MYSQL_HOST=db_sendy \
  -e MYSQL_PASSWORD=db_password \
  bubbajames/sendy:tag

... where sendy is the name you want to assign to your container, campaigns.example.com is your FQDN of Sendy server, db_sendy is your database server instance, db_password is the database user's password and tag is the tag specifying the Sendy version you want. See the list of tags above.

Environment Varaibles

SENDY_PROTOCOL (Optional)

HTTP protocol used in Sendy APP_PATH (http or https). Default: http

SENDY_FQDN (required)

The fully qualified domain name of your Sendy installation. This must match the FQDN associated with your license. You can purchase a license here.

MYSQL_HOST (required)

The MySQL server hosting your Sendy database.

MYSQL_DATABASE (optional)

The Sendy database name. Default: sendy.

MYSQL_USER (optional)

Database user. Default: sendy.

MYSQL_PASSWORD (required)

Database user's password. Not recommended for sensitive data! (see: Docker Secrets)

Docker Secrets

As an alternative to passing sensitive information via environment variables, _FILE may be appended to the previously listed environment variables, causing the initialization script to load the values for those variables from files present in the container. In particular, this can be used to load passwords from Docker secrets stored in /run/secrets/<secret_name> files. (See repository for sample secrets)

For example:

$ docker run -d --name sendy -e MYSQL_PASSWORD_FILE=/run/secrets/mysql-root -d sendy

Using Dockerfile

Pretty minimalistic Dockerfile as everything you need is already bundled. Just provide environment variables or environment file.

FROM bubbajames/sendy:4.1

# ... additional apache/php configurations here ... 
# e.g. copy your SSL Certificate and apache configurations if not using a load balancer.  

Start a Sendy instance

The following starts an instance specifying an environment file.

$ docker run -d -name sendy --env_file sendy.env -p 80:80 sendy

Sample environment file

SENDY_FQDN=campaigns.example.com
MYSQL_HOST=db_sendy
MYSQL_DATABASE=sendy
MYSQL_USER=sendy
MYSQL_PASSWORD_FILE=/run/secrets/db_password
# MYSQL_PASSWORD=db_password

Using docker-compose

Starts an HAProxy load balancer instance for SSL termination, a Sendy instance and a MySQL database instance with mounted volume for persisted data between restarts. Also uses Docker Secrets to avoid exposing sensitive data via 'inspect'.

The latest docker-compose.yml and sample files are available from the image repository. It is highly advised to clone this repository to ensure the latest samples are used.
