Prerequisites

Before you begin, ensure that you have the following installed:
  • Docker
  • Docker Compose (if using the Docker Compose setup)

​
Option 1: Production Docker Compose Setup

This setup includes PostgreSQL, Redis and the Unsend application.
  1. Download the Docker Compose file from the Unsend repository: compose.yml
  2. Navigate to the directory containing the compose.yml file.
  3. Create a .env file in the same directory. Copy the contents of .env.selfhost.example
  4. Run the following command to start the containers:
docker-compose --env-file ./.env up -d
This will start the PostgreSQL database, Redis and the Unsend application containers.
  1. Access the Unsend application by visiting http://localhost:3000 in your web browser.

​
Option 2: Standalone Docker Container

If you prefer to host the Unsend application on your container provider of choice, you can use the pre-built Docker image from DockerHub or GitHub’s Package Registry. Note that you will need to provide your own database and SMTP host.
  1. Pull the Unsend Docker image:
docker pull unsend/unsend
Or, if using GitHub’s Package Registry: 
docker pull ghcr.io/unsend-dev/unsend
  1. Run the Docker container, providing the necessary environment variables for your database and SMTP host:
docker run -d \
  -p 3000:3000 \
  -e NEXTAUTH_URL="<your-nextauth-url>"
  -e NEXTAUTH_SECRET="<your-nextauth-secret>"
  -e DATABASE_URL="<your-next-private-database-url>"
  -e REDIS_URL="<your-next-private-redis-url>"
  -e AWS_ACCESS_KEY="<your-next-private-aws-access-key-id>"
  -e AWS_SECRET_KEY="<your-next-private-aws-secret-access-key>"
  -e AWS_DEFAULT_REGION="<your-next-private-aws-region>"
  -e GITHUB_ID="<your-next-private-github-id>"
  -e GITHUB_SECRET="<your-next-private-github-secret>"
  unsend/unsend
Replace the placeholders with your actual database and aws details.
  1. Access the Unsend application by visiting the URL you provided in the NEXTAUTH_URL environment variable in your web browser.
