Fly.io ​

Fly.io is a public cloud built for developers who ship.

Electric and Fly ​

You can use Fly to deploy any or all components of the Electric stack:

Fly's sweet spot is deploying Elixir applications, like the Electric sync service and/or Phoenix aplications.

See the Deployment guide for more details.

Deploy Postgres ​

Fly isn't really a managed Postgres host. They do offer database hosting but they prefer to offload it to other providers, such as Supabase.

Deploy Electric ​

Copy the following config into a file called fly.toml, replacing the app name and DATABASE_URL:

toml
app = "YOUR_UNIQUE_APP_NAME"

[build]
  image = "electricsql/electric:latest"

[env]
  DATABASE_URL = "postgresql://..."
  ELECTRIC_DATABASE_USE_IPV6 = true

[http_service]
  internal_port = 3000
  force_https = true

  [[http_service.checks]]
    interval = "10s"
    timeout = "2s"
    grace_period = "20s"
    method = "GET"
    path = "/v1/health"

Using the flyctl client, in the same directory as fly.toml, run:

shell
flyctl launch --copy-config --ha=false

Hit the health check endpoint to verify that everything is running OK:

console
$ curl https://YOUR_UNIQUE_APP_NAME.fly.dev/v1/health
{"status":"active"}

Deploy your app ​

You can run most kinds of apps on Fly, including static sites.
