December 2025 monthly summary for terraform-ibm-modules/terraform-ibm-base-ocp-vpc: Key features delivered: - Kube Audit Module Image Reference Security and Compatibility Update: Updated the default kube-audit image tag and digest to align with security baselines and compatibility requirements. Updated related docs and variable definitions to reflect the new image reference; enhanced test configurations to ignore specific updates and destroys for kube-audit to stabilize CI. Major bugs fixed: - Security/compatibility alignment fix for kube-audit image reference (commit included): reduces runtime drift and mitigates potential security exposure by ensuring the audited module uses a current and compatible image tag/digest. Overall impact and accomplishments: - Strengthened security posture for the OpenShift VPC module by ensuring kube-audit uses a current and validated image reference. - Improved CI stability by refining tests to ignore non-critical kube-audit updates/destroys, reducing flaky test runs. - Streamlined maintenance with updated documentation and clear variable references, easing onboarding and future changes. Technologies/skills demonstrated: - Kubernetes audit module management and image digest/tag management - Terraform module maintenance and versioning discipline - Documentation and variable schema updates - Test configuration and CI stability improvements - Change coordination within a repository focused on cloud-native infrastructure (OpenShift on IBM Cloud)

April 2025 focused on stabilizing and standardizing WatsonX infrastructure by upgrading the account infrastructure addons to RG-only v2.0.6 across data, discovery, governance, and orchestrate (including RG-only config upgrade for orchestrate). The AI module saw a dependency version consistency fix by aligning to v2.0.6, and the KMS all-inclusive module introduced two new Data Access variations (Fully configurable and Security-enforced) with deprecation of the standard variation, along with updates to pipelines. These changes improved deployment stability, feature parity, and security posture across environments, reducing drift and accelerating feature adoption. Demonstrated technologies include Terraform module upgrades, RG-only configuration patterns, version management, and secure networking/configuration updates.
