Introduction

The recommended way to build the production version of your Latitude project is as a Docker container. This approach is useful if you want to deploy your app on your own infrastructure or you want to use one of the many Docker-based PaaS providers as your deployment target.

​
Docker container

You will need the Docker CLI installed in your machine.
Every Latitude project is equipped with a Dockerfile to facilitate containerization. To build the Docker container for your Latitude project, proceed as you would with any other Docker project: 
docker build . -t my-latitude-app
Once the build is complete, you can test your app locally with: 
docker run -p 3000:3000 my-latitude-app
See the docker build documentation for more details.

​
Environment variables in production builds

Keep in mind .env variables are not available in production builds for security reasons – you should use environment variables instead. You can set them in the Dockerfile or pass them as arguments when running the container. For example, if you had a .env file with the following content: 
LATITUDE__DB_PASSWORD=mypassword
You could pass the environment variable to the container like this: 
docker run -p 3000:3000 -e LATITUDE__DB_PASSWORD=mypassword my-latitude-app
