NuoDB OpenShift CE Template

Public repository for the NuoDB CE OpenShift template.

Image Availability

The templates reference images stored in the RHCC / Registry. Other images exist in case you don't have a RHCC account. The templates are parameterized so you can alter which image you pull. The set of permissible images are as follows:

image operating system default RHEL 7.5 yes
nuodb/nuodb-ce:latest CentOS 7.5 no



We recommend that you perform your demo using three (3) or four (4) nodes. However, because your clusters may have more nodes than that, and you may want to dedicate particular nodes for testing NuoDB, the templates are set up to permit isolating NuoDB to specified nodes using labels.

While you can run the CE template on a single host, this is not recommended as you will end up running the transaction engine, storage manager, administration tier, and client driver -- all on one host.


If you're following along at the command line, create a new project to test NuoDB out in:

$ oc new-project test
Now using project "test" on server "".

You can add applications to this project with the 'new-app' command. For example, try:

    oc new-app centos/ruby-22-centos7~

to build a new example application in Ruby.


To permit isolating the NuoDB CE demo onto dedicated OpenShift nodes, you must add one label if you're running the ephemeral template, and two labels if you are running the persistent template. In each case, the values for the labels are irrelevant for the CE version, as the templates simply check for their existence. The following table outlines the labels, their applicability, etc:

label description ephemeral persistent default availability zone or set of nodes to run nuodb on yes yes none type of node, typically storage no yes none

Label three or four nodes with the label, any value.

Label ONLY one node with the label, with any value.

All pods will run on those labeled nodes only.

For example, to add labels:

$ oc project test
Already on project "test" on server "".

$ oc get nodes -L -L

$ oc label node ip-10-0-2-152.ec2.internal
node "ip-10-0-2-152.ec2.internal" labeled

To delete the labels when you're all done:

$ oc label node ip-10-0-2-152.ec2.internal
node "ip-10-0-2-152.ec2.internal" labeled

Your cluster should look something like this in the end with regards to labeling:

$ oc get nodes -L -L
NAME                         STATUS    ROLES     AGE       VERSION             ZONE      NODE-TYPE

Disable THP

All nodes where you run NuoDB MUST have transparent huge pages (THP) disabled. Follow instructions online for details on how to do this.

Create Volumes (Persistent Template ONLY)

The persistent template requires the creation of a storage class and the creation of a volume. To do so, copy the local-disk-class.yaml file to your master, and install the template:

$ oc create -f local-disk-class.yaml
storageclass "local-disk" created
persistentvolume "local-disk-0" created

Create Red Hat Registry Credentials

First, on the master, login to the Red Hat Registry (sample commands below):

$ docker login
Username: bbuck-nuodb
Login Succeeded

Verify you can pull the image:

$ docker pull

Create a Pull Secret:

$ oc create secret generic nuodb-docker --from-file=.dockerconfigjson=${HOME}/.docker/config.json
secret "nuodb-docker" created

$ oc secrets link default nuodb-docker --for=pull

Import Template and Go!

Using the OpenShift UI, import and run the template. Follow online instructions found at

Cleaning Up


$ oc delete project test
project "test" deleted
