GCP

Setting up Truefoundry control plane on your own cloud involves creating the infrastructure to support the platform and then installing the platform itself.

​

Setting up Infrastructure

​

Requirements

These are the infrastructure components required to set up a production grade Truefoundry control plane.

​

Permissions Required

We will be using OCLI (Onboarding CLI) to create the infrastructure. We will be using a locally setup gcloud CLI. Please make sure the user or service account authenticated with GCP has the following permissions -

• Cloud SQL Admin - roles/cloudsql.admin
• Security Admin - roles/iam.securityAdmin
• Service Account Admin - roles/iam.serviceAccountAdmin
• Service Account Token Creator - roles/iam.serviceAccountTokenCreator
• Service Account User - roles/iam.serviceAccountUser
• Storage Admin - roles/storage.admin

​

GCP Infra Architecture

​

Run Infra Provisioning using OCLI

​

Prerequisites

1. Install git if not already present.

2. Setup gcloud CLI

   1. Install gcloud cli == 474.x.x
   2. Install gke-gcloud-auth-plugin
   3. Authenticate with a user that has the above mentioned roles - gcloud auth application-default login
   4. Set the project to be used for infra creation - gcloud config set project truefoundry-devtest

​

Installing OCLI

1. Download the binary using the below command.

   Apple silicon MacOS (arm64))

   Intel MacOS (amd64)

   Linux (arm64)

   Linux (amd64)

   curl -H 'Cache-Control: max-age=0' -s "https://releases.ocli.truefoundry.tech/binaries/ocli_$(curl -H 'Cache-Control: max-age=0' -s https://releases.ocli.truefoundry.tech/stable.txt)_darwin_arm64" -o ocli
   

2. Make the binary executable and move it to $PATH

   Shell

   sudo chmod +x ./ocli
   sudo mv ocli /usr/local/bin
   

3. Confirm by running the command

   Shell

   ocli --version
   

​

Configuring Input Config file

1. To create a new cluster, you would require your GCP Project ID and Region

2. Run the following command to fill in the inputs interactively

   Shell

   ocli infra-init
   

3. For networking, there are two possible configurations:

   1. New VPC (Recommended) - This creates a new VPC for your new cluster.
   2. Existing VPC - You can enter your existing VPC and subnet IDs.

4. Once all the inputs are filled, a config file with the name tfy-config.yaml would be generated in your current directory

5. Modify the file to enable control plane installation by setting gcp.tfy_control_plane.enabled: true. Below is the sample for the same:

aws: null
azure: null
binaries:
  terraform:
    binary_path: null
  terragrunt:
    binary_path: null
gcp:
  cluster:
    master_cidr_block: 172.16.0.32/28
    name: <cluster_name>
    pod_range_name: pods
    service_range_name: services
    version: "1.28"
  network:
    additional_ranges: []
    existing: false
    network_name: ""
    pod_cidr: 10.244.0.0/16
    service_cidr: 10.255.0.0/16
    shared_vpc:
      enabled: false
      network_name: ""
      project_id: ""
      subnet_name: ""
    subnet_cidr: 10.10.0.0/16
    subnet_id: ""
  network_tags: []
  project:
    id: <project-name>
  region:
    availability_zones:
      - asia-south1-b
      - asia-south1-a
      - asia-south1-c
    name: asia-south1
  tags: {}
  tfy_control_plane:
    enabled: true
provider: gcp

​

Create the cluster

Run the following command to create the GKE cluster and IAM roles needed to provide access to various infrastructure components as per the inputs configured above.

ocli infra-create --file tfy-config.yaml

This command may take around 30-45 minutes to complete.

In the last step the database credentials will be printed. Make sure to note them down.

​

Installation

​

Installation steps

1. Make sure that kubectl context is set to the newly created cluster.

2. Install argoCD -

   kubectl create namespace argocd
   kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/core-install.yaml
   

3. Add the truefoundry helm repo

   helm repo add truefoundry https://truefoundry.github.io/infra-charts/
   helm repo update
   

4. We will create a values.yaml for the helm chart installation -

   1. Download the values.yaml from helm chart repo -

      curl https://raw.githubusercontent.com/truefoundry/infra-charts/main/charts/tfy-k8s-gcp-gke-standard-inframold/values-cp.yaml > values.yaml
      

   2. Fill in the tenant_name, cluster_name, truefoundry_image_pull_config_json and tfy_api_key in the downloaded file. You can get these from the Truefoundry team
   3. Also fill in the database section with database creds. If you created the infrastructure using OCLI, you can get the credentials by running ocli output

5. Apply the helm chart with the values.yaml

   helm install -n argocd inframold truefoundry/tfy-k8s-gcp-gke-standard-inframold --version 0.0.16 -f values.yaml
   

​

Test the installation

1. Port forward the frontend application to access the Truefoundry dashboard -

   kubectl port-forward svc/truefoundry-truefoundry-frontend-app -n truefoundry 5000
   

2. Access the truefoundry dashboard from a browser by opening http://localhost:5000. You can login with the username and password provided by the Truefoundry team.
3. Now you are ready to connect a cluster to the Truefoundry platform and get deploying. Go here for the directions. You can also onboard the same cluster as the control plane
