Google Cloud deployment tutorial

Preparation

1. Install Google Cloud SDK
2. Login to gcloud: gcloud auth login
3. Create a project: gcloud projects create project-name. You need to invent your own cute project name here.
4. Select the project: gcloud config set project parcs-name.
5. You need to enable Cloud and Billing API using Google Cloud Console here (you will be prompted to do so later otherwise).
6. Set region and zone: gcloud config set compute/zone europe-north1-a, gcloud config set compute/region europe-north1.
7. Configure firewall: gcloud compute
 firewall-rules create allow-all --direction=INGRESS --priority=1000 --network=default --action=ALLOW --rules=all --source-ranges=0.0.0.0/0

Instance creation

1. Create the master instance: gcloud compute instances
create-with-container master
--container-image=registry.hub.docker.com/hummer12007/parcs-node
--container-env PARCS_ARGS="master"

Example output:

NAME    ZONE             MACHINE_TYPE   PREEMPTIBLE  INTERNAL_IP  EXTERNAL_IP    STATUS
master  europe-north1-a  n1-standard-1               10.166.0.2   35.228.130.74  RUNNING

You need to record the external IP, it will be referred to as $MASTER_IP later.

2. Create the workers (you can create as many as you wish): gcloud compute instances create-with-container worker1 worker2 worker3
--container-image=registry.hub.docker.com/hummer12007/parcs-node
--container-env PARCS_ARGS="worker 10.166.0.2"

3. The PARCS web interface will be available at http://$MASTER_IP:8080
