Nok Nok S3 Suite Cloud Deployment Toolkit
Version: 9.4.0.139_6.153
Issues fixed
When you bring your own images containing the guest operating system, Java runtime, or Tomcat, setting a local JAVA_HOME environment variable can cause a permission denied error when initializing the database.
Previous Behavior: When a customer sets the value of the JAVA_HOME environment variable, they receive a permission denied error when initializing the database.
New Behavior: Customers set the values of the NN_JAVA_HOME and the NN_CATALINA_HOME environment variables and receive no error when they initialize the database.
After installing Kubernetes or Docker, an attempt to access the Tutorial web app generates the error Failed to fetch configuration.
Previous Behavior: After installing Kubernetes or Docker, an attempt to access the Tutorial web app generates the error Failed to fetch configuration.
New Behavior: After installing Kubernetes or Docker, accessing the Tutorial web app URL does not generate an error.
Installation requirements
Host machine
The Docker Compose CDT package and the Kubernetes CDT package may be used with any one of the following system configurations to build and run Nok Nok S3 Suite images. You may also use one of these environments to build your Docker images and then run them on any other Docker runtime environment such as AWS ECS or Google Cloud.
The CDT for Docker Compose requires the following Docker resources:
4 CPU, 6 GB RAM and 100 GB disk
The CDT Helm charts use the Ingress-Nginx controller for routing requests to Kubernetes services. For production deployments, Nok Nok recommends using Ingress controllers or load balancers native to the deployment platform.
Also for production deployments, ensure that Kubernetes components and other artifacts are up-to-date from a security perspective.
Rocky Linux
Linux instance running Rocky Linux 9.4
Docker Engine (Docker CE) 25.0.3 or later
The CDT for Kubernetes running on Rocky Linux requires the following Kubernetes resources:
4 CPU, 12 GB RAM and 100 GB disk
MacOS
MacOS: Tahoe 26.2
Rancher Desktop 1.21 or later.
The CDT for Kubernetes running on MacOS requires the following Kubernetes resources:
4 CPU, 8 GB RAM and 100 GB disk
Guest machine
The Cloud Deployment Toolkit deploys the Nok Nok Servers on RedHat UBI 9. If you need to use a different guest operating system, you can use your own custom container base image. See Use Your Own Images in Install using Docker and in Install using Kubernetes.
