What configuration steps should a Portworx Administrator perform to ensure that Portworx can use the...

Comprehensive and Detailed Explanation From Exact Extract:

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】.
