Install scripts to run Meteor on Google Compute Engine.

1. Create a new project on GCE:
   https://console.developers.google.com/

2. Download the gcloud tool:
   https://developers.google.com/cloud/sdk/

3. Authenticate to Google Cloud Platform:
   gcloud auth login

4. Configure gcloud to use your new project by default:
   gcloud config set project <YOUR_PROJECT_ID>

5. Create a bucket in Google Cloud Storage (it needs to be unique) for example:
   gsutil mb gs://iloveq42

6. Edit startup.sh to use your bucket. For example:
   export BUCKET='iloveq42'

7. Copy startup.sh (replace 'iloveq42' with your bucket name):
   gsutil cp startup.sh gs://iloveq42

8. Bundle your Meteor app into the parent directory:
   meteor build .. --architecture os.linux.x86_64

9. Copy your app to your bucket (replace 'iloveq42' with your bucket name):
   gsutil cp ../<YOUR_APP_NAME>.tar.gz gs://iloveq42/versions/default.tar.gz

10. Create a new persistent disk for MongoDB:
    gcloud compute disks create "mongo-data" --size "200GB" --zone "europe-west1-d" --type "pd-standard"

11. Create a compute engine instance using the startup.sh script (replace 'iloveq42' with your bucket name):
    gcloud compute instances create "meteor" --zone "europe-west1-d" --tags "http-server" --scopes storage-ro --metadata startup-script-url=gs://iloveq42/startup.sh --disk "name=mongo-data" "mode=rw" "boot=no"

This will output something like this:

NAME   ZONE           MACHINE_TYPE  INTERNAL_IP   EXTERNAL_IP   STATUS
meteor europe-west1-d n1-standard-1 10.240.134.93 130.211.62.68 RUNNING

Done! At this point your site should be reachable on the external IP (http://130.211.62.68 in this case).
