Install SAP Data Intelligence 3.0 on an RKE Cluster


Read our free white paper: How to Build a Kubernetes Strategy

Rancher and SAP have been working on a dedicated verification of SAP Data Intelligence 3 (SAP DI) on Rancher Kubernetes Engine (RKE) cluster and Longhorn storage platform. This blog will guide you on how to properly install SAP DI on an RKE cluster.

Learn more about at Installation Guide for SAP Data Intelligence.

Install an RKE Cluster

First, we need to install an RKE cluster where we’ll install SAP DI.

Node Requirements

  • RKE node requirements
  • NFS support is required to install SAP Data Intelligence on a Kubernetes cluster. Each node of the K8s cluster must be able to export and mount NFS V4 volumes.
    • Kernel modules nfsd and nfsv4 must be loaded.
    • System utilities mount.nfs, mount.nfs4, umount.nfs and unmount.nfsv4 must be present on the nodes:
    • If the kernel of your nodes supports the NFS modules, SAP Data Intelligence will load the necessary modules automatically. For this, the rpcbind daemon must be running in the nodes.
    • If you have configured your Kubernetes nodes for NFS, you can disable the NFS module loading using the SLCB by choosing Advanced Installation for Installation Mode, and choose Disable Loading NFS Modules for Loading NFS Modules.

Deploy RKE Cluster

You can deploy your RKE cluster in two ways:

Note: At the moment, SAP DI supports Kubernetes versions up to 1.15.X (check SAP PAM for K8s version update). Be sure to specify the correct kubernetes_version on your RKE deployment. Learn more in the SAP Note 2871970 (SAP S-user required).

RKE Cluster Architecture for Production

In addition to using one of the above methods to install an RKE cluster, we recommend the following best practices for creating the production-ready Kubernetes clusters that will run your apps and services.

  • Nodes should have one of the following roles configurations:
    • Separated planes roles:
    • etcd
    • control plane
    • worker
    • Mix overlapped planes roles:
    • etcd and control plane
    • worker (the worker role should not be used or added on nodes with the etcd or control plane role)
  • RKE cluster should have one of the following nodes configurations:
    • Separated planes nodes:
    • 3 x etcd
    • 2 x control plane
    • 3 x worker
    • Mix overlapped planes nodes:
    • 3 x etcd and control plane
    • 3 x worker
  • If needed, increase etcd nodes count (recommended odd values) for higher node fault toleration and spread them across (availability) zones to provide even better fault tolerance.
  • Enable etcd snapshots. Verify that snapshots are being created, and run a disaster recovery scenario to verify the snapshots are valid. The state of your cluster is stored in etcd, and losing etcd data means losing your cluster. Make sure you configure etcd Recurring Snapshots for your cluster(s) and make sure the snapshots are stored externally (off the node). You can find more information at recurring snapshots.


We used RKE v1.1.1 to deploy a test RKE cluster. RKE install details are here.

We’ve deployed our RKE cluster on an AWS infrastructure with the following properties:

  • using Kubernetes overlapped planes (etcd, control and worker)
  • on 3 m5.2xlarge AWS instances:
    • 8 CPUs,
    • 32GB RAM
    • 100GB storage
  • using ami-06d9c6325dbcc4e62, ubuntu 18.04
  • using 3 public elastic ips (one per node)
  • using route53 subdomain wildcard pointing to public elastic ips *
    • Docker registry:
    • SAP DI vsystem:

Once you’ve deployed your infrastructure, cluster.yaml file has been created and RKE is up.

cat << EOF > cluster.yaml
  - address: <ELASTIC_IP_1>
    internal_address: <INTERNAL_IP_1>
    ssh_key_path: <AWS_KEY_FILE>
    user: ubuntu
      - controlplane
      - etcd
      - worker
    ssh_key_path: <AWS_KEY_FILE>
  - address: <ELASTIC_IP_2>
    internal_address: <INTERNAL_IP_2>
    user: ubuntu
      - controlplane
      - etcd
      - worker
    ssh_key_path: <AWS_KEY_FILE>
  - address: <ELASTIC_IP_3>
    internal_address: <INTERNAL_IP_3>
    user: ubuntu
      - controlplane
      - etcd
      - worker
    ssh_key_path: <AWS_KEY_FILE>
kubernetes_version = "v1.15.11-rancher1-3"
rke up --config cluster.yaml

Once RKE finishes cluster deployment, kubeconfig will be generated on the current directory.

Note: Don’t use this example in a production environment. Overlapped planes are not recommended for production environments. Get more information about provisioning Kubernetes in a production cluster.

SAP DI Prerequisites

Take care of the following SAP DI prerequisites before install.

There are a couple of optional features that will require S3 compatible storage:

RKE storageClass

You need to define a default storageClass on your RKE cluster for SAP DI to work properly. SAP DI services should be able to generate a PersistentVolume PV and a PVC on your RKE cluster.

SAP DI installation has been tested on two distinct default storageClasses:

  • Longhorn v1.0.0 for production environments:
  • local_path storageClass, for testing or ephemeral environments (not supported for production):
    • Install kubectl apply -f
    • Set as default kubectl patch storageclass local-path -p '{"metadata": {"annotations":{"":"true"}}}'

S3 storage

If you are planning to use any optional features that require S3 compatible storage, we tested these S3 backends successfully:

More info at storage infrastructure requirements (SAP S-user required).

TLS Certificates

To manage TLS certificates for the installation, we’ve decided to install cert-manager into the RKE cluster. TLS certificates are required to access container registry and SAP DI portal once installed.

kubectl -n cert-manager apply -f
helm repo add jetstack
helm install --name cert-manager --namespace cert-manager --version v0.14.3 jetstack/cert-manager

Learn more about using self-signed certs.

Container Registry

SAP DI requires a container registry in order to mirror SAP Docker images. You need at least 60GB of free storage to fit all the Docker images. If you already have one Docker registry up and running, please jump to the next section.


To automate the TLS management, we’ll deploy a cert-manager issuer using letsencrypt integration. That allows Kubernetes to manage letsencrypt certificates automatically. This can be replaced by other kinds of certificates.

# Create issuer acme on kube-system
cat << EOF > docker-registry-issuer.yaml
kind: Issuer
  name: letsencrypt-prod
    app: "docker-registry"
      name: letsencrypt-prod-key
    - http01:
          class: nginx

kubectl -n kube-system apply -f docker-registry-issuer.yaml

Docker Registry

Install docker-registry from helm chart, exposing and securizing it by ingress

# Install docker-registry
helm install docker-registry stable/docker-registry --namespace default  
--set ingress.enabled=true 
--set ingress.hosts[0] 
--set ingress.annotations.nginx\.ingress\.kubernetes\.io/proxy-body-size="0" 
--set ingress.annotations.cert-manager\.io/issuer=letsencrypt-prod 
--set ingress.annotations.cert-manager\.io/issuer-kind=Issuer 
--set ingress.tls[0].secretName=tls-docker-registry-letsencrypt,ingress.tls[0].hosts[0]

Install SAP DI

See the full SAP DI installing guide for details.

Generate stack.xml from SAP Maintenance Planner

Follow this procedure to install SL Container Bridge.

There are 3 installation options available:

  • SAP DATA INTELLIGENCE 3 - DI - Platform extended
  • SAP DATA INTELLIGENCE 3 - DI - Platform full Bridge

Once the installation option is selected, save the generated MPStack*.xml file.

Note: We chose SAP DATA INTELLIGENCE 3 - DI - Platform full Bridge for the example.

Deploy SAP SL Container Bridge

SAP SL Container Bridge (SLCB) is required to install SAP DI. Download SLCB software:

# downloaded proper version from SAP
mv SLCB01_<PL>-70003322.EXE /usr/local/bin/slcb

Once you’ve downloaded SLCB, deploy it on your RKE cluster. RKE cluster kubeconfig file is required:

slcb init
# select advance config and set nodePort on installation

Note: If you are doing an airgap installation, please follow these instructions.

Deploy SAP DI

Once SLCB is deployed, it’s time to deploy SAP DI. To do that, you need a generated MP_Stack_*.xml file and Kubernetes slcbridgebase-service service information:

# Get slcbridgebase-service info, NODE_IP:NODE_PORT
kubectl -n sap-slcbridge get service slcbridgebase-service
# Execute slcb with proper arguments
slcb execute --useStackXML software/MP_Stack_2000913929_20200513_.xml --url https://NODE_IP:NODE_PORT/docs/index.html
# Choose option `3: - SAP DATA INTELLIGENCE 3 - DI - Platform full Bridge`

Note: As an option, SLCB could be executed from MP in web mode following these instructions. Service slcbridgebase-service should be exposed to the internet.

Installation parameters (used as example):

  • namespace: sap
  • docker-registry:
  • SAP s user: sXXXXXXXXX
  • system password: XXXXXXXX
  • tenant: rancher
  • user: rancher
  • pass: XXXXXXXX

Check SAP DI Deployment

Once SLCB execution is finished, check that everything is running on the SAP DI namespace:

kubectl -n sap get all

Post Installation

Now that our SAP DI deployment is up and running, let’s check that installation and all provided web portals are working properly. Find more information at Post-Installation Configuration of SAP DI.

Expose SAP System Management

By default, the SAP DI System Management portal is not exposed. In the example, we are using Ingress to expose and secure it. Learn more at Expose SAP DI System Management.

  • In order to automate the TLS management, we’ve deployed a cert-manager issuer using letsencrypt integration. That means that Kubernetes will manage letsencrypt certificates automatically. This can be replaced by other kinds of certificates.
# Create issuer acme on sap namespace
cat << EOF > sap-di-vsystem-issuer.yaml
kind: Issuer
  name: letsencrypt-prod
    app: "sap-di-vsystem"
      name: letsencrypt-prod-key
    - http01:
          class: nginx
kubectl -n sap apply -f sap-di-vsystem-issuer.yaml
  • Create vsystem ingress rule using cert-manager issuer and FQDN,
# Create vsystem ingress
cat << EOF > sap-di-vsystem-ingress.yaml
apiVersion: extensions/v1beta1
kind: Ingress
  annotations: nginx "true" "true" HTTPS "0" 16k "30" "1800" "1800" "letsencrypt-prod" Issuer
  name: vsystem
  - host:
      - backend:
          serviceName: vsystem
          servicePort: 8797
        path: /
  - hosts:
    secretName: tls-vsystem-letsencrypt
kubectl -n sap apply -f sap-di-vsystem-ingress.yaml

Cert-manager issuer needs a few minutes to generate the TLS letsencrypt certificate. Once the TLS certificate is ready, vsystem service should be available at

More info at Testing Your Installation


Rancher and SAP have been working on RKE and Longhorn validation as a supported Kubernetes distribution and storage platform to deploy SAP DI in production.

Partial Validation

Validation is not complete – it’s around 90 percent. The item that is not complete is:

  • ML test pipeline: Run SAP ML test pipeline in the platform.

More info

In this blog, we showed you how to install SAP DI software with common options. However, we did not cover all of them. Please refer to SAP documentation to learn more:
