5. Deploying Bento on GCP¶
This is the user documentation on provisioning bento on AWS.
The purpose of this guide is to provide instructions on how to provision and deploy Bento Framework on GCP using google kubernetes engine. This guide assumes that the Custodian has an operating account with Google Cloud Platform.
This instructions assumed you have a google account and a project with billing enabled. In addition, you will need terraform and git installed.
The code in this demo will create the following resources via Terraform:
A new VPC and new VPC subnets
A Cloud NAT router for egress access from the VPC subnets
A GCE Instance serving as a Bastion Host
A Private GKE Cluster with two nodes running two services - frontend and backend
Neo4j Database in private subnets
Clone Bento Custodian repository
bento@custodian:~$ git clone https://github.com/CBIIT/bento-custodian
Change directory to gke workspace
bento@custodian:~$ cd bento-custodian/terraform/gke
Authenticate gcloud client
bento@custodian:~$ gcloud auth login
Create google project. The name of the project can be anything you want or you may run gcloud config set project PROJECT_NAME to use existing project where PROJECT_NAME is the name of your project.
bento@custodian:~$ gcloud projects create PROJECT_NAME
Configure gcloud to use the newly created project or you use existing one.
bento@custodian:~$ gcloud config set project PROJECT_NAME
Create service account. Note you can name it anything you want, in this example I am calling it bento-sa
bento@custodian:~$ gcloud iam service-accounts create bento-sa
List and copy the email address of the service account
bento@custodian:~$ gcloud iam service-accounts list NAME EMAIL DISABLED email@example.com False
Create a credential key for the service account. Note the name of the file can be anything but ensure it ends with .json. Google allows other file formats but in this example I will be using json format.
bento@custodian:~$ gcloud iam service-accounts keys create gcloud_api_key.json --firstname.lastname@example.org
Get your Billing Account ID
bento@custodian:~$ BILLING_ACCOUNT=$(gcloud beta billing accounts list | cut -d " " -f1 | grep -v "ACCOUNT_ID")
Link your project to Billing account
bento@custodian:~$ gcloud beta billing projects link bento-cloudrun --billing-account $BILLING_ACCOUNT
Enable google cloud services apis
bento@custodian:$ gcloud services enable cloudresourcemanager.googleapis.com bento@custodian:$ gcloud services enable iam.googleapis.com bento@custodian:$ gcloud services enable cloudbilling.googleapis.com bento@custodian:$ gcloud services enable compute.googleapis.com bento@custodian:$ gcloud services enable run.googleapis.com bento@custodian:$ gcloud services enable vpcaccess.googleapis.com
Grant IAM roles to the service account
bento@custodian:$ gcloud projects add-iam-policy-binding bento-cloudrun --member serviceAccount:email@example.com --role roles/owner
Generate SSH Keys. We need to generate ssh key in order to connect to the database instance and the bastion host that we will be creating.
Enter ssh-keygen -t rsa -f FILENAME at the prompt as shown below
bento@custodian:~$ ssh-keygen -t rsa -f bento-ssh-key
Hit Enter key for the question Enter passphrase (empty for no passphrase) to skip password. Hit Enter key again for the confirmation Enter same passphrase again
Generating public/private rsa key pair. Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in bento-ssh-key. Your public key has been saved in bento-ssh-key.pub.
Your ssh key will be generated at the location specified. Note you will have two files, one is your private key and the other is the public key with .pub extension
Edit Terraform vars.tfvars file. Using your favorite editor, open vars.tfvars file. At minimum you will need to provide value to the following.
public_ssh_key = name of the ssh public key generated earlier
private_ssh_key = name of the ssh private key generated earlier
gcp_auth_file = name of the service account key generated earlier
gcp_region = gcp region to use for this deployment
gcp_project = name of the gcp project created earlier
stack_name = can be anything
service_account_id = name of the service account created earlier
Run terraform init
bento@custodian:~$ terraform init
Run terraform plan to see what resources will be created.
bento@custodian:~$ terraform plan -var-file=vars.tfvars
Review the output of the above command. It will show all the resources to be created.
Run terraform apply to provision your Bento environment
bento@custodian:~$ terraform apply -var-file=vars.tfvars -auto-approve
At this point if there are no errors your custodian will be provisioned. Navigate to the url listed at the end of the terraform output. Note it will take about 10 minutes for the application to completely deployed.
Outputs: backend_url = https://bento-cloudrun-backend-rxpxr4ih3q-uk.a.run.app bastion_host_private_ip = 172.16.1.2 bastion_host_public_ip = 220.127.116.11 db_private_ip = 192.168.5.2 frontend_url = https://bento-cloudrun-frontend-rxpxr4ih3q-uk.a.run.app service_id = firstname.lastname@example.org
Navigate to frontend_url in your browser.
Run terraform destroy to destroy the resources provisioned.
terraform destroy -var-file=vars.tfvars -auto-approve
