Installation

This exercise provides instructions for installing the Self Hosted Controller in a Google Cloud environment.

Note

You must setup and configure a GCP virtual machine, GKE cluster, and a Postgres database before doing this exercise.


Install Self Hosted Controller

  • Click here to login and download the controller installation package to the instance

  • From your home directory, untar the package using the command below

tar -xf rafay-controller-*

Example:

tar -xf rafay-controller-1.13-19-gke.tar.gz
  • Copy and edit the config.yaml file.

    cp -rp config.yaml-gke-tmpl config.yaml
    vi config.yaml
    
  • Customize the config.yaml. The following are settings that should be updated.

    deployment:
        type: "GKE"   # Supports "airgap", "EKS", "GKE" and "AKS".
    database:
        external-database: true
        postgressql:            #For GKE and air gap
            host: "10.63.192.3" #<Enter Private Database IP> 
            port: "5432"
    dns:
        enabled: true
        gke:
            serviceAccount: ""  #Enter DNS service account email 
    backup_restore:
        enabled: true
        restore: false
        schedule: "*/10 * * * *"  #"*/10 * * * *" #Takes backup of rafay-core namespace every 10 min
        bucketName: "" #GKE Storage Bucket name
        gke:
            serviceAccount: ""  #Enter GKE Bucket service account email
    repo: # change the paths to match the virtual machine 
    app-config: 
        partner:
            star-domain: # the DNS FQDN for the controller
    override-config:
        global.external_lb: "false"
    

Creating database secrets using radm

Replace the <"public ip"> placeholder with the public ip of the database instance. Default root-user is postgres

sudo ./radm database --host <"public ip"> --kubeconfig <config file from gke cluster> --port 5432 --root-password <postgres db password> --root-user <postgres db username>

Example:

sudo ./radm database --host "34.122.136.181" --kubeconfig gke-config.yaml --port 5432 --root-password postgres --root-user postgres

Installing self hosted controller dependencies

Install the self hosted controller dependencies which are required for the controller.

sudo ./radm dependency --config config.yaml --kubeconfig <gke cluster config file>

Example:

sudo ./radm dependency --config config.yaml --kubeconfig gke-config.yaml

Installing Controller Application

Install the Controller Application

sudo ./radm application --config config.yaml --kubeconfig <gke cluster config file>

Example:

sudo ./radm application --config config.yaml --kubeconfig gke-config.yaml

This will bring up all the self hosted controller services.

Note

This process will take approx 20-30 mins for all pods to be up and ready.

Before proceeding further, confirm that all pods are in running state using kubectl.

kubectl get pods -A --kubeconfig <gke cluster config file>

Example:

kubectl get pods -A --kubeconfig gke-config.yaml


Accessing the Web Console

Try accessing the self hosted controller https://console. to verify that the installation was successful.

  • A screen appears similar to the image below when accessing the UI

GKE

  • Click the Sign Up link to create the first Organization of the rafay air-gapped controller

  • Register a new account for the organization as below screenshot

GKE

  • Try to login to this Organization with the newly registered account on the login screen

Upload Cluster Dependencies

Run the below command to enable support for Kubernetes cluster provisioning from the Rafay air-gapped controller and upload dependencies for Kubernetes cluster provisioning to the controller.

sudo ./radm cluster --config config.yaml --kubeconfig <gke cluster config file>

Example:

sudo ./radm cluster --config config.yaml --kubeconfig gke-config.yaml
