Install the Fly.io CLI

Log in to Fly.io with flyctl auth login

Run flyctl launch to create a new app on Fly.io and configure it. It will ask you to select a region and a name for your app. When done it will create a fly.toml file and a Dockerfile in your project directory.

Set GEL_INSTANCE and GEL_SECRET_KEY as secrets in your Fly.io app.

For runtime secrets, you can do this by running the following commands:

$ 

flyctl secrets set GEL_INSTANCE <GEL_INSTANCE>

$ 

flyctl secrets set GEL_SECRET_KEY <GEL_SECRET_KEY>

For build secrets, you can do this by modifying the Dockerfile to mount the secrets as environment variables.

# Build application
 RUN pnpm run build
 RUN --mount=type=secret,id=GEL_INSTANCE \
     --mount=type=secret,id=GEL_SECRET_KEY \
     GEL_INSTANCE="$(cat /run/secrets/GEL_INSTANCE)" \
     GEL_SECRET_KEY="$(cat /run/secrets/GEL_SECRET_KEY)" \
     pnpm run build

Deploy your app to Fly.io

$ 

flyctl deploy

If your app requires build secrets, you can pass them as arguments to the deploy command:

$ 
  

flyctl deploy --build-secret GEL_INSTANCE="<GEL_INSTANCE>" \
  --build-secret GEL_SECRET_KEY="<GEL_SECRET_KEY>"
