How to deploy Remix to AWS

Run Remix on ECS Fargate behind an Application Load Balancer.

Prerequisites

A Git repository containing your application and its production build command.
A Ravion account with your AWS account connected. Start free at Ravion signup.
The Ravion CLI installed and authenticated. See CLI installation.

The examples use my-org/my-app as a placeholder. Replace it with your repository before applying the config.

Set up this Remix app for Ravion ECS hosting.

Configure the deployment

Ravion provisions the VPC, cluster, service, and ALB in your AWS account. This example uses Railpack for the build. Use build_source: dockerfile instead when you need a custom Dockerfile. For the current Remix Vite workflow, npm run build creates build/server/index.js and build/client. Start the server with npm start or your adapter’s documented start command.

ravion.yaml

project:
  givenId: remix-app
  name: Remix app
environments:
  - givenId: production
    name: Production
    moduleInstances:
      - givenId: network
        name: Network
        type: rvn-aws-network
        version: 1.0.0
        input:
          aws_account_id: ravion-prod
          aws_region: us-east-1
          name: remix-production
      - givenId: cluster
        name: ECS cluster
        type: rvn-ecs-cluster
        version: 1.0.0
        input:
          network:
            moduleGivenIdRef: network
          name: remix-production
      - givenId: web
        name: Remix web service
        type: rvn-ecs-web
        version: 1.0.0
        input:
          cluster:
            moduleGivenIdRef: cluster
          name: remix-production-web
          build_source: railpack
          source_repo: my-org/my-remix-app
          railpack_build_cmd: npm run build
          railpack_start_cmd: npm start
          container_port: 3000
          fargate_size:
            vcpu: 0.5
            memory_gb: 1

Set runtime configuration in environment_variables and keep secrets in secrets. Use the port supplied by ECS through PORT.

Apply and connect your domain

ravion project create --given-id remix-app --name "Remix app"
ravion project config apply remix-app --file ravion.yaml --dry-run
ravion project config apply remix-app --file ravion.yaml

Use custom domains to attach your hostname.
