February 2025 monthly summary: Delivered a set of focused improvements across the Cloud Platform repositories that enhance documentation, observability, and infrastructure reliability, driving clearer guidance for developers and more robust deployment pipelines. Key contributions spanned four repos with notable business value and technical depth: Key features delivered: - ministryofjustice/cloud-platform-user-guide: Concourse pipelines documentation improvements, clarifying roles of plan-live and apply-namespace pipelines, documenting apply-live pipelines and APPLY_PIPELINE_SKIP_THIS_NAMESPACE, renaming concourse-pipelines.html.md.erb for better navigation, and updating failure handling explanations. - ministryofjustice/cloud-platform-terraform-concourse: Live reporting configuration and S3-backed storage for live reports (including environment-based paths and secret storage); enhanced error reporting by collecting failing namespaces as JSON in S3; environment checker and tooling references updated. - ministryofjustice/cloud-platform-infrastructure: Added ECR support for github-teams-filter service, integrated github teams filter service into components, and configured S3 bucket for apply-live namespace reports; introduced Route53 hosted zone for external DNS testing; ext-dns zones added for test clusters. - ministryofjustice/cloud-platform-cli: Polished Slack build failure notifications with link to skip-namespace documentation; Unicode handling fix in secret decoding and related SKIP reference cleanup. Major bugs fixed: - Fixed Unicode handling in decodeSecret, reverted a prior decoding change, and simplified JSON formatting for secret data; updated SKIP documentation link for clarity. - Scheduling adjustment for environments-live resource to align with operational window; several ACL/role-related and module-name fixes across cloud-platform-infrastructure-related components. - Resolved MPC alert webhook/channel issues and improved reliability of alert routing; corrected ECR module naming and ensured sensitive outputs for SSM parameters. Overall impact and accomplishments: - Significantly improved developer onboarding and operational clarity through documentation improvements and naming guidelines. - Increased deployment reliability and observability via S3-backed live reporting and structured error data; better failure visibility across namespaces and environments. - Hardened infrastructure with safer secrets handling, clearer alerting, and more robust environment tooling and DNS/testing configurations. Technologies/skills demonstrated: - Concourse CI/CD, Terraform, Kubernetes, AWS S3, ECR, Route53; Slack integrations; JSON data handling; Unicode handling in decodeSecret; documentation discipline and versioned changelogs.
