Installation - CPU Only¶
For managed Kubernetes solutions (AKS, EKS, GKE) or on-prem (kubeadm) Kubernetes variants, follow this generic guide to install the Kinetica Operators, Database and Workbench.
Preparation & Prequisites
Please make sure you have followed the Preparation & Prequisites steps
Install the helm chart¶
Run the following Helm install command after substituting values from section 3
helm -n kinetica-system install \
kinetica-operators kinetica-operators/kinetica-operators \
--create-namespace \
--values values.onPrem.k8s.yaml \
--set db.gpudbCluster.license="LICENSE-KEY" \
--set dbAdminUser.password="PASSWORD" \
--set global.defaultStorageClass="DEFAULT-STORAGE-CLASS"
Check installation progress¶
After a few moments, follow the progression of the main database pod startup with:
until it reaches "gpudb-0 3/3 Running" at which point the database should be ready and all other software installed in the cluster. You may have to run this command in a different terminal if the helm command from step 4 has not yet returned to the system prompt. Once running, you can quit this kubectl watch command using Ctrl+C.
error no pod named gpudb-0
If you receive an error message running kubectl -n gpudb get po gpudb-0 -w informing you that no pod named gpudb-0 exists. Please check that the OpenLDAP pod is running by running
kubectl -n gpudb get pods
kubectl -n gpudb describe pod openldap-5f87f77c8b-trpmf
where the pod name openldap-5f87f77c8b-trpmf is that shown when running kubectl -n gpudb get pods
Validate if the pod is waiting for it's Persistent Volume Claim/Persistent Volume to be created and bound to the pod.
Accessing the Kinetica installation¶
Target Platform Specifics¶
If you are installing into a managed Kubernetes environment and the NGINX ingress controller that is installed as part of this install creates a LoadBalancer service, you may need to associate the LoadBalancer with the domain you plan to use.
As of now, the kinetica-operator chart installs NGINX ingress controller. So after the installation is complete, you may need to edit the KineticaCluster Custom Resource and Workbench Custom Resource with the correct domain name.
Option 1: Use the LoadBalancer domain
kubectl get svc -n kinetica-system
# look at the loadbalancer dns name, copy it
kubectl -n gpudb edit $(kubectl -n gpudb get kc -o name)
# replace local.kinetica with the loadbalancer dns name
kubectl -n gpudb edit $(kubectl -n gpudb get wb -o name)
# replace local.kinetica with the loadbalancer dns name
# save and exit
# you should be able to access the workbench from the loadbalancer dns name
Option 2: Use your custom domain Create a record in your DNS server pointing to the LoadBalancer DNS. Then edit the KineticaCluster Custom Resource and Workbench Custom Resource with the correct domain name, as mentioned above.
Installing on a local machine which does not have a domain name, you can add the following entry to your /etc/hosts file or equivalent:
Note
The default chart configuration points to local.kinetica but this is configurable.
Installing on a bare metal machines which do not have an external hardware loadbalancer requires an Ingress controller along with a software loadbalancer in order to be accessible.
Kinetica for Kubernetes has been tested with kube-vip
