May 2025 (2025-05) — Key features delivered across two core repositories focused on container baseline maintenance to strengthen security, stability, and build reproducibility. Key features delivered: - idpay-onboarding-workflow: Docker Base Image Upgrade to newer Amazon Corretto JDK and Maven. This upgrade supports improved security posture, stability, and performance of both build and runtime environments. Commit: 170a389dd04ecb306bcf6a215dd8853fd61d4392 ("chore: amazoncoretto sha update (#274)"). - idpay-admissibility-assessor: Docker base image checksum update to lock to latest Amazon Corretto JDK/runtime versions. This ensures builds use the intended, up-to-date components and minimizes drift. Commit: d35a4a782ec2f163003c2b8a37b1af2c43f5c57d ("chore: amazoncoretto sha update (#305)"). Major bugs fixed: - None reported in this period. Focused maintenance updates to base images rather than defect fixes. Overall impact and accomplishments: - Strengthened security posture by ensuring the latest supported Amazon Corretto/JDK/runtime are used across two critical services. - Improved build stability and reproducibility through explicit SHA-based base image pinning, reducing drift between environments. - Reduced risk exposure from outdated containers and accelerated safe deployments by aligning environments with current baselines. Technologies/skills demonstrated: - Dockerfile/container image maintenance, JDK/Maven lifecycle awareness, and version pinning via SHA checksums. - Cross-repo consistency in base image strategy and traceable changes via commit messages. - Basic security hygiene and release discipline in CI/CD contexts. Business value: - Compliance with security baselines, lower operational risk, and faster, more reliable deployments through standardized, up-to-date container bases.
