Deploy a Meilisearch instance on Railway


    This guide explains how to deploy a ready-to-use Meilisearch instance on Railway.

    Railway is a deployment platform where you can provision infrastructure, develop with that infrastructure locally, and then deploy to the cloud.

    Railway aims to be the simplest way to develop, deploy, and diagnose issues with your application.


    To follow along, you need a Railway account. If you don't have one, you can visit the link above and click on "Login" in the top right corner to log in either with your GitHub account or email.

    Environment Variables

    MEILI_ENV: by default, this template sets the MEILI_ENV environment variable to production. If you would like access to the Meilisearch search preview, update MEILI_ENV to development.

    MEILI_MASTER_KEY: replace the MEILI_MASTER_KEY environment variable with a strong key to secure your Meilisearch instance.

    If you want to quickly generate a secure random key, you can run the following command from your terminal:

    openssl rand -base64 48

    To define the desired length of your password, you can either add | cut -c-${DESIRED_LENGTH} or | head -c${DESIRED_LENGTH} to the command as such:

    openssl rand -base64 48 | cut -c1-32
    openssl rand -base64 48 | head -c32

    which in this case will generate a 32-character long string.


    Setting a master key is optional, but without it, your server will accept unidentified requests, which can affect your usage quota on the server. If you need some protection in production, we strongly recommend setting a master key.

    Test Meilisearch

    If you have set the MEILI_ENV environment variable to development in the Railway service, you will have access to the Meilisearch search preview.

    Copy the public URL (for example, of your project from your Railway account dashboard and paste it into your browser.

    Railway dashboard

    You should land on the Meilisearch search preview, where you will be asked to enter your master key.
