Fly.io installation guide

1. Create account and login at https://fly.io.
2. Setup two factor authentication under Account->Settings->2FA.
3. Logout and login again using 2FA.

Using homebrew

brew install flyctl

Or using installer script

curl -L https://fly.io/install.sh | sh

Login with the fly auth cmd

fly auth login

First, create a local directory for your fly application.

mkdir cradle-cms
cd cradle-cms

Then create the app.

fly app create cradle-cms

List the available fly regions and note the region id of the datacenter you want to deploy to (primary_region).

fly platform regions

Edit or create a fly.toml configuration file with a text-editor.

You can use this simple template for the app and change the configuration options (site, frontend and admin) specified in the [env] section.

app = 'cradle-cms'
primary_region = ''
[env]
  TLS = false
  PORT = 8080
  ADMIN_USER = 'admin'
  ADMIN_EMAIL = 'your@email.invalid'
  ADMIN_PASS = 'your secret password'
[http_service]
  internal_port = 8080
  force_https = true
  auto_stop_machines = true
  auto_start_machines = true
  min_machines_running = 0
  processes = ["app"]
[[vm]]
  memory = '512mb'
  cpu_kind = 'shared'
  cpus = 1
[mounts]
  source="storage"
  destination="/storage"
  processes = ["app"]
  initial_size = "3gb"

Set primary_region to the fly datacenter you prefer i.e the one being closest to you.

NOTE: since fly terminates https we must specify TLS = false and configure the web server to listen on PORT = 8080.

Cradle-cms is deployed as a docker image so you need podman or docker installed on your computer.

With the docker or podman cli installed, login to our registry using your cradle-cms licence key and your account password.

docker login registry.cradlecms.com

NOTE: You might need to specify port :5000 on the registry url.

Then fetch the latest cradle-cms release.

docker pull --platform linux/amd64 registry.cradlecms.com/cradle-cms:latest

NOTE: As fly.io only supports linux/amd64 containers you should specify --platform linux/amd64 when downloading the image.

Then authenticate against fly.io docker registry

fly auth docker

Tag the local cradle-cms release which we will push to the fly application registry.

docker tag registry.cradlecms.com/cradle-cms:latest registry.fly.io/cradle-cms:latest

Then upload the image to the fly registry.

docker push registry.fly.io/cradle-cms:latest

Now you can start cradle-cms with the deployed image.

fly deploy --image=registry.fly.io/cradle-cms:latest

Then open a browser using the url that fly has assigned to your application.

Login to the admin with the username and password you specified in the configuration file.

NOTE: For better security you can configure the system using fly secrets instead.

Also there's a lot more configuration options available, but we've tried to keep things simple to begin with.

Logs

The system log is written to standard out in json format so you can use tools such as jq to filter log messages. To see the log output you need to use docker logs as shown in the example.

docker logs -f <container id>
    

You can also subscribe to a log event stream using the nats client. 

nats subscribe "logs.>"

[#6] Received on "logs.frontend"
{"time":"2024-09-28T08:54:26.176Z","level":"INFO","service":"frontend","msg":"render","host":"localhost:5000","site":"17427f63-e498-4654-bcaa-a6f24afabeef","path":"/","type":"index","handle":"","lang":"en"}
    

Use the log stream if you want to store the log on another server or monitor it in real time.
