When using shared authentication in Portworx, the Kubernetes secret that contains the authentication token or credentials is stored in the same namespace where the application requesting storage resides. This placement ensures that the application pods have access to the secret needed to authenticate to Portworx for volume provisioning and management. It enables a security boundary aligned with Kubernetes namespaces, restricting credentials to the scope of the application. Storing the secret in the default namespace or the Portworx installation namespace would be less secure or less flexible in multi-tenant clusters. Portworx authentication documentation highlights this design for efficient, secure access management in Kubernetes environments【Pure Storage Portworx Security Guide†source】.

When integrating Portworx with an S3 Object Store secured by a custom or third-party certificate that is not signed by a public Certificate Authority (CA), administrators must manually provide the relevant CA certificate to Portworx. This involves creating a Kubernetes secret that contains the custom CA certificate and referencing this secret in the StorageCluster manifest through environment variables. This allows Portworx components to trust the certificate during TLS handshake with the S3 endpoint, avoiding connection failures due to untrusted certificates. Without this step, Portworx cannot securely communicate with the object store. The Portworx security and installation documentation highlights this practice as essential for secure Object Store integration in private or regulated environments where internal or custom PKIs are used【Pure Storage Portworx Security Guide†source】.

The Portworx OCI monitor pod primarily monitors the health of Kubernetes nodes within the cluster. It collects telemetry data and status updates about node health, resource availability, and connectivity to ensure the Kubernetes environment hosting Portworx pods remains stable and reliable. This monitoring is vital to detect node failures, performance degradation, or resource bottlenecks early, enabling prompt remedial action. The OCI monitor acts as a specialized component interacting with the Kubernetes control plane and Portworx services to provide real-time node health insights. This role is distinct from installation facilitation or network policy management, focusing instead on operational observability. Official Portworx operator and observability documentation describe the OCI monitor’s function as critical for node health monitoring and overall cluster reliability within Kubernetes environments running Portworx storage【Pure Storage Portworx Observability Docs†source】.
