First experiences with SAP Data Hub 1.4.0 on SUSE CaaS Platform 3.0 RC1

After having installed SAP Data Hub 1.4.0 on SUSE CaaSP 2.0, I am wondering what difference there was installing it on SUSE CaaSP 3.0.

To start with, the SUSE CaaSP 3.0 installer warns me, that version 3.0 RC1 is still a Beta Distribution, which is fine for my sandbox installation:

Besides this, the installation appears very similar to SUSE CaaSP 2.0:

The first obvious improvements come with the Initial CaaS Platform Configuration that now allows me to configure the:

  • Overlay network settings
  • Proxy settings
  • SUSE registry mirror
  • Container runtime
  • System wide certificate

Under the hood, mainly the Kubernetes and Tiller versions seem to have changed:

SUSE CaaS Platform 2.0 SUSE CaaS Platform 3.0
Kubernetes 1.8.10 Kubernetes 1.9.8
sles12/caasp-dex:2.7.1 sles12/caasp-dex:2.7.1
gcr.io/kubernetes-helm/tiller:v2.6.2 sles12/tiller:2.8.2
sles12/kubedns:1.0.0 sles12/kubedns:1.0.0
sles12/dnsmasq-nanny:1.0.0 sles12/dnsmasq-nanny:1.0.0
sles12/sidecar:1.0.0 sles12/sidecar:1.0.0

 

But most importantly, Pod Security Policies are now being enabled by default with two out of the box Pod Security Policies:

  • unprivileged (Default assigned to all users)
  • privileged

Since SAP Data Hub 1.4.0 Replica Set vsystem-vrep needs to create a privileged container, I chose to deploy the least restricted policy you can create, equivalent to not using the pod security policy admission controller: policy/privileged-psp.yaml.

With this the SAP Data Hub 1.4.0 deployment completes even smoother than on SUSE CaaSP 2.0:

With Velum offering me these additional settings:

  • Registries
    • Remote Registries
    • Mirrors
    • System wide certificates
  • Kubernetes
    • Compute Resource Reservations
    • Auditing

Overall, SUSE CaaS Platform 3.0 RC1 leaves a quite positive impression with me to run SAP Data Hub 1.4.0, so that I am looking forward to the final release.
