Jul 1, 2025

July 2025 monthly summary for the opencloud repository focusing on deployment reliability and data transfer performance. Delivered two critical updates across opencloud-eu/opencloud: fixed Docker build version propagation and enabled multipart S3 uploads by default in the Storage-Users service. These changes reduce build/versioning errors, improve large-file upload throughput, and enhance deployment reproducibility, contributing to faster delivery cycles and stronger operator confidence.

Jun 1, 2025

June 2025 monthly summary for opencloud-eu/reva. Focus: enhancing file listing metadata with preview signals. Implemented oc:has-preview property in PROPFIND responses to indicate whether a file has a preview available, differentiating between containers and files and using supported MIME types to determine preview availability. This enables clients to render preview cues and avoids unnecessary fetches when previews are not supported.

April 2025

Apr 1, 2025

April 2025 performance summary: Delivered core platform improvements across opencloud-eu/opencloud and opencloud-eu/docs, focusing on release reliability, authentication integration, and CI/CD efficiency. Highlights include robust daily build versioning, LDAP/Keycloak integration with autoprovisioning, and streamlined release processes. Documentation consolidation added architecture diagrams and deployment guidance, including Keycloak-LDAP authentication details. Overall impact: more reliable releases, stronger security, and faster onboarding for developers and operators, with improved traceability and reduced maintenance overhead. Technologies demonstrated: Git-based versioning, LDAP/Keycloak integration, environment provisioning, and CI/CD automation.

Mar 1, 2025

March 2025 monthly summary for OpenCloud EU repositories focused on stabilizing release pipelines, accelerating builds, and strengthening versioning discipline across docs, opencloud, web, and reva. Delivered container builds, release automation readiness, CI/CD hardening, and Docker/Alpine optimizations—driving faster, more reliable releases and an improved security posture across the portfolio.

February 2025

4 Commits • 4 Features

Feb 1, 2025

February 2025 monthly work summary focusing on documentation automation, CI/CD enhancements, and production deployment automation across two repositories (opencloud-eu/opencloud and opencloud-eu/docs). Implementations include docs scaffolding and automated publishing, CI-based development docs fetch, tag-triggered production deployment, and SSH log verbosity cleanup. These changes reduce manual steps, accelerate releases, and improve observability and reliability of deployments.

Jan 1, 2025

January 2025 – OpenCloud (opencloud-eu/opencloud): Branding alignment, deployment configuration improvements, and a critical startup fix. This month focused on ensuring branding consistency across build and deployment artifacts, stabilizing the Docker-based deployment workflow, and eliminating startup issues caused by binary naming/path mismatches.

Dec 1, 2024

December 2024: Opencloud-eu/opencloud stabilization focused on Traefik routing configuration. Reverted a readability-focused Traefik labels change to restore the prior stable configuration for TLS certificate resolvers and entrypoints. Core functionality remained unchanged; no user-facing feature releases this month. This rollback preserved security posture and service exposure, reducing risk of TLS misconfiguration and regressions, and improved maintainability for upcoming work. Commit 65f057e812fe024e524aad8c6e295ba60fa3c845.
