CI/CD Deployment

You can use CI/CD platforms like Github Actions to re-deploy your application automatically whenever changes are pushed to your repository.

Re-deploying from CI/CD

Prerequisites

Make sure to first deploy your application from your local machine using wasp deploy <provider> launch. The launch command creates the services your application needs in the deployment provider (your app and its database) and deploys your app. After your application is deployed, you are able to use wasp deploy <provider> deploy in a CI/CD workflow to re-deploy it.

Deployment steps

To automate deployment, you need to create a workflow file in your repository that specifies the deployment process when a new commit is pushed to the repository.

The workflow needs to include the following steps:

1. Checkout the code from the repository
2. Install Node.js and the Wasp CLI
3. Install any provider-specific dependencies
4. Deploy the application using wasp deploy <provider> deploy

To be able to deploy your apps to the deployment providers, you need to set provider-specific API keys in the environment variables. How you set environment variables depends on the CI/CD platform you are using. We'll show you how to do this for Github Actions in the next section.

Github Actions workflow

Let's take a look at an example CI/CD workflow for Github Actions for each of the supported providers.

Fly.io

You'll need an organisation token to deploy to Fly.io. You can generate the token by running fly tokens create org and adding it to your repository secrets as FLY_API_TOKEN.

.github/workflows/deploy.yml

name: Wasp Deploy

on:
  push:
    branches:
      - main

jobs:
  deploy:
    runs-on: ubuntu-latest
    env:
      WASP_VERSION: "0.25"

    steps:
      - uses: actions/checkout@v6

      - name: Setup Node.js
        uses: actions/setup-node@v6
        with:
          node-version: "24.14.1"

      - name: Install Wasp
        # We pin the Wasp CLI version to avoid issues when a new Wasp version is released.
        run: npm i -g @wasp.sh/wasp-cli@$WASP_VERSION

      - name: Install Flyctl
        uses: superfly/flyctl-actions/setup-flyctl@master

      - name: Deploy
        run: wasp deploy fly deploy
        env:
          # You must add FLY_API_TOKEN to your Repository Secrets
          FLY_API_TOKEN: ${{ secrets.FLY_API_TOKEN }}

Railway

You'll need an account token to deploy to Railway. You can generate it by going to your account settings under Tokens and generating a token without selecting a workspace. Set the token as a repository secret named RAILWAY_API_TOKEN.

Make sure to replace my-project-name with the actual name of your project and MY_PROJECT_ID with the actual ID of your project. You can find the project ID in the project's settings.

        env:
          # You must add RAILWAY_API_TOKEN to your Repository Secrets
          RAILWAY_API_TOKEN: ${{ secrets.RAILWAY_API_TOKEN }}
