July 2026 Monthly Summary: Focused on delivering reliable environment-specific tooling, robust CI/CD improvements, and secure infrastructure for staging/production. Delivered concrete capabilities that improve operational reliability, deployment consistency, and security posture across MOJ environments. Key features delivered, major fixes, and impact: - Manual Snapshot Management and UAT Controls (cla_backend): Implemented hourly and timestamped snapshot naming, environment-specific scheduling, and configuration toggles to optimize backup behavior in UAT. Included YAML value updates for UAT and safe disabling of cron-based backups to prevent unintended runs. - Build and CI/CD Workflow Improvements (cla_backend): Enhanced build and CI/CD configurations with environment targeting, optional parameters, and improved Docker workflow consistency; updated Dockerfile to a specific version and refined workflow input targets to reduce pipeline failures. - Terraform service accounts for staging and production with GitHub Actions integration (cloud-platform-environments): Provisioned Kubernetes service accounts for laa-legal-adviser-api-staging and laa-legal-adviser-api-production using the cloud-platform-terraform-serviceaccount module, enabling secure CI/CD pipelines and secret management via GitHub Actions. Overall impact and accomplishments: - Increased reliability and predictability of backups in UAT through automated, timestamped snapshots and environment-scoped scheduling. - More deterministic and faster release cycles due to targeted CI/CD workflows and Docker build optimizations. - Stronger security and governance for multi-environment deployments by codifying service accounts and integrating them with GitHub Actions. Technologies/skills demonstrated: - Terraform and Kubernetes service accounts; GitHub Actions integration; Docker, Dockerfile version pinning; YAML-based CI/CD pipelines; environment targeting and feature toggles; infrastructure-as-code practices.
