What are some common commands and operations?

Common operations include deploying OpenShift applications using `oc apply -f `, managing pods with `oc get pods`, and viewing logs with `oc logs `. Configuration is managed through YAML files.

What APIs does zCX Foundation for OpenShift expose?

zCX Foundation for OpenShift exposes the standard OpenShift API, which is a REST API. You can interact with it using `oc` command-line tool or any Kubernetes-compatible client. API endpoints follow the Kubernetes API patterns, such as `/api/v1/pods`.

How is security handled in zCX Foundation for OpenShift?

zCX Foundation for OpenShift uses z/OS Security Server (RACF, ACF2, or Top Secret) for authentication and authorization. It supports role-based access control (RBAC) for managing permissions within the OpenShift environment.

What is the business value of zCX Foundation for OpenShift?

zCX Foundation for OpenShift enables you to run containerized applications on z/OS, leveraging the platform's reliability, security, and performance. This allows you to modernize applications while maintaining z/OS qualities of service.

How does zCX Foundation for OpenShift help reduce costs?

By running OpenShift on z/OS, you can consolidate workloads and reduce infrastructure costs. zCX Foundation for OpenShift allows you to leverage existing z/OS resources and skills.

How does zCX Foundation for OpenShift enable application integration?

zCX Foundation for OpenShift allows you to integrate containerized applications with existing z/OS applications and data. This enables you to create hybrid applications that leverage the strengths of both environments.

What authentication methods are supported?

zCX Foundation for OpenShift integrates with z/OS Security Server (RACF, ACF2, or Top Secret) for authentication. It also supports standard OpenShift authentication methods, such as OAuth 2.0 and OpenID Connect.

What access control model is used?

zCX Foundation for OpenShift uses role-based access control (RBAC) to manage permissions. You can define roles and assign them to users or groups to control access to resources.

What encryption is used and where?

Data in transit is encrypted using TLS. Data at rest can be encrypted using z/OS encryption facilities. OpenShift secrets are used to manage sensitive information.

What audit/logging capabilities exist?

zCX Foundation for OpenShift logs security-related events to z/OS System Management Facilities (SMF). These logs can be used for auditing and compliance purposes.

What administrative interfaces are available?

zCX Foundation for OpenShift provides a command-line interface (CLI) and a web console for administration. The CLI is based on the `oc` command-line tool. The web console is the standard OpenShift web console.

How is user management handled?

User management is handled through z/OS Security Server (RACF, ACF2, or Top Secret) and OpenShift's identity providers. You can integrate with existing identity management systems.

What are the main configuration parameters?

Key configuration parameters include network settings, resource limits, and security policies. These parameters are configured through OpenShift YAML files and z/OS parmlib members.

What monitoring/logging capabilities exist?

zCX Foundation for OpenShift provides monitoring and logging capabilities through OpenShift's built-in tools, such as Prometheus and Elasticsearch. You can also integrate with z/OS monitoring tools, such as IBM Z Monitoring Suite.

Product Overview

zCX Foundation for OpenShift provides a platform for deploying Red Hat OpenShift containers on z/OS. It creates a dedicated z/OS address space for OpenShift, enabling integration with z/OS resources and capabilities. This is similar in function to z/OS Container Extensions (zCX) but is tailored for OpenShift containers rather than Docker containers.

The architecture includes several key components: the OpenShift control plane, compute nodes running within z/OS address spaces, and the container runtime. Communication between these components uses standard Kubernetes protocols, such as gRPC and HTTP/2. The OpenShift API, a REST API, is exposed for programmatic interaction.

Configuration is managed through OpenShift YAML files and z/OS parmlib members. Security is integrated with z/OS Security Server (RACF, ACF2, or Top Secret), supporting role-based access control (RBAC) for fine-grained permission management. Monitoring and logging are facilitated through OpenShift's built-in tools like Prometheus and Elasticsearch, with integration options for z/OS monitoring tools, such as IBM Z Monitoring Suite.

Network requirements include standard Kubernetes networking configurations and z/OS network connectivity.
