Tugtainer delivers a visual command center for Docker environments that automates container image updates, monitors registry releases, and manages application lifecycles across multiple servers without command-line intervention. System administrators can inspect running containers across all connected hosts, trigger immediate image pulls, and configure automated cron schedules for recurring health and registry checks. Flexible update policies allow teams to flag production databases as notification-only while automatically updating stateless web applications whenever new image tags publish. When updating linked services, the platform analyzes Docker Compose project definitions and custom dependency labels to stop and restart containers in strict dependency order, preventing broken network links and orphaned volume mounts. Administrators can authenticate private container registries, browse image layers and tags, and view real-time container log streams directly within the browser console. Automated pruning jobs continuously reclaim server disk space by deleting obsolete, untagged images and dangling build layers after successful deployments. Multi-channel alerting integrates with over fifty notification providers, delivering real-time update summaries and error warnings directly to Discord, Telegram, Slack, and email webhooks. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
