This article is designed to share an idea of testing/working with Viya4 on custom made environments, locally, in cloud, or wherever.

 

 

First of all prepare 4 VMs, 12 vCPU, 24 GB RAM each. Ubuntu 20.04 LTS. Here's my example:

# 1. VMKUB01 Master node : Ubuntu 20.04 LTS, 500 GB Storage Space, 24 GB RAM, 12 vCPU
# 2. VMKUB02 Worker node 1 : Ubuntu 20.04 LTS, 200 GB Storage Space, 24 GB RAM, 12 vCPU
# 3. VMKUB03 Worker node 2 : Ubuntu 20.04 LTS, 200 GB Storage Space, 24 GB RAM, 12 vCPU
# 4. VMKUB03 Worker node 3 : Ubuntu 20.04 LTS, 200 GB Storage Space, 24 GB RAM, 12 vCPU

 

You cannot deploy Viya4 on single machine, kubernetes doesn't allow to run 110+ pods on one node :). You could use whole script or do this step by step to better understand what's going on.

Remember that 80% is preparing cluster.. 20% is Viya files configuration and deployment.

 

Scripts and whole idea are designed in some steps:

  1. Prepare VMs.
  2. Prepare files from portal.
  3. 1st Script on master node:
    • # Step 1 , preinstall
    • # Step 2 , Kubernets install
    • # Step 3, turn off swap
    • # Step 4, OS Tuning
    • # Step 5, Installing more packets
    • # Step 6, Docker install
    • # Step 7, create kubernetes cluster
    • # Step 8, Install kubernetes networking - calico and metallb
    • # Step 9, Install helm
    • # Step 10, Install ingress
    • # Step 11, Install and configure NFS Server
    • # Step 12, Install NFS Subdir External Provisoiner
    • # Step 13, Creating pod security policies
    • # Step 14, check if NFS works
    • # Step 15, SCP files to workers
  4. Script on each worker node:
    • # Step 1 , preinstall
    • # Step 2 , Kubernets install
    • # Step 3, turn off swap
    • # Step 4, OS Tuning
    • # Step 5, Installing more packets
    • # Step 6, Docker install
    • # Step 7, Joining kubernetes cluster
  5. Now you should be able to list working nodes
    sudo su -l root
    root@vmkub01:~# kubectl get nodes
    NAME STATUS ROLES AGE VERSION
    vmkub01 Ready control-plane,master 2d15h v1.21.5
    vmkub02 Ready <none> 2d15h v1.21.5
    vmkub03 Ready <none> 2d15h v1.21.5
    vmkub04 Ready <none> 2d15h v1.21.5
  6. Install portainer (it's quite helpful)
    root@vmkub01:~# kubectl get all -n portainer
    NAME                             READY   STATUS    RESTARTS   AGE
    pod/portainer-5d6dbf85dd-2mdtl   1/1     Running   1          2d15h
    
    NAME                TYPE           CLUSTER-IP       EXTERNAL-IP    PORT(S)                                        AGE
    service/portainer   LoadBalancer   10.111.183.207   10.0.110.101   9000:31659/TCP,9443:31248/TCP,8000:30691/TCP   2d15h
    
    NAME                        READY   UP-TO-DATE   AVAILABLE   AGE
    deployment.apps/portainer   1/1     1            1           2d15h
    
    NAME                                   DESIRED   CURRENT   READY   AGE
    replicaset.apps/portainer-5d6dbf85dd   1         1         1       2d15h
  7. 2nd Script on Master node:
    • # Step 1, Install Kustomize
    • # Step 2, Install CertManager
    • # Step 3, Create CA and Issuer with CertManager for full-TLS deployment
    • # Step 4, deploying operator
    • # Step 5, building directory structure
    • # Step 6, Installation
      • # Namespace
      • # Ingress
      • # TLS
      • # StorageClass
      • # License
      • # SAS Orchestration
      • # Install
  8. After some time check status of sasoperator with
    kubectl -n sasoperator get sasdeployment
    
    root@vmkub01:~# kubectl -n sasoperator get sasdeployment
    NAME STATE CADENCENAME CADENCEVERSION CADENCERELEASE AGE
    sas-viya SUCCEEDED stable 2021.1.6 20211104.1636065570555 2d11h

I really enjoyed watching progress with portainer 🙂

 

Prepare deployment files from portal (mine are):

License file : SASViyaV4_9XXXXX_0_stable_2021.1.6_license_2021-10-21T071701.jwt
Certs file : SASViyaV4_9XXXXX_certs.zip
TGZ file : SASViyaV4_9XXXXX_0_stable_2021.1.6_20211020.1634741786565_deploymentAssets_2021-10-21T071710.tgz

At the installation time use same account (it helps a lot) with same pw at each machine. My account is called gabos

After successful OS installation log in via ssh by your account on Master node.

Copy via scp or any other manager your deployment files to /home/gabos/ (your account ofc)

Edit new file (vi script.sh), paste whole script below and edit it with your needs (variables), make it executable (chmod +x script.sh), and run.

 

1st Script on master node :

#!/bin/bash

# This script is designed and released by Gabos Software, feel free to use it and make it better


## Configuration section, it has important variables in order to prepare whole environment. 
# It's hardcoded for environemnt like :

Very cool! A couple things I noticed:
We currently require kustomize version 3.7.0, so your "snap install kustomize" might need to instead pull and extract https://github.com/kubernetes-sigs/kustomize/releases/download/kustomize%2Fv3.7.0/kustomize_v3.7.0_l... into your PATH (it doesn't look like kustomize 3.7.0 is listed as a snap release).
You are creating a cert-manager issuer "sas-viya-issuer" in your sandbox namespace. The assets in sas-bases/overlays/cert-manager-issuer also creates an issuer by that name (tied to the sas-viya-self-signing-issuer) so this may be confusing.

I will look into documentation and verify scripts, if some steps should be changed - I'll update it 😉

Hey @gwootton , I've reviewed configuration and :

1. Line with kubectl apply -f CAAtuhority.yaml could be disabled in order to prevent creating sandbox namespace with custom CA and sas-viya-issuer

2. I haven't found any official clues about kustomize version, where did you find that ? I looked through 2021.1.6 deployment guide and found none.

 

In some days I will open project on gitlab with scripts 🙂

Here's the documentation link for 2021.1.6 showing a kustomize version requirement of 3.7.0:

SAS Viya Operations - Virtual Infrastructure Requirements - Kubernetes Client Machine Requirements
