Changelog

November 2025

Command palette search. Press Cmd+K to search across projects, servers, and actions from anywhere in the dashboard.
Upgrade daemon from dashboard. Check for updates and upgrade the daemon directly from the web UI without SSH.
Dark mode. The dashboard now respects system color scheme preferences.
Zero downtime deploys. Deployments now wait for DNS propagation and port availability before routing traffic, eliminating brief 502 errors on new deploys.
Stale deployment cleanup. Orphaned deployment containers are now automatically cleaned up on daemon startup.

Better deployment timeout feedback. When a service fails to start, the output now shows which port was being waited on and for how long.
DNS verification before routing. Traffic is only sent to new services after both internal DNS resolution and port checks pass.

Docker log rotation. Container logs are now automatically rotated to prevent disk exhaustion on long-running services.
Disk usage in stats. The disco stats command now includes disk usage alongside CPU and memory.
Cron timeout configuration. Set custom timeouts for cron jobs via cronTimeout in disco.json.
Volume import through Cloudflare. Fixed volume imports failing when the server is behind a Cloudflare tunnel.

Health checks. Services can now define health check endpoints in disco.json, used to verify readiness before routing traffic.
Domain validation. Domain names are now validated before being added to prevent typos and invalid configurations.
Services panel. The dashboard now shows all running services for a project with their status and scale.
SSH keys with passphrases. disco init now supports SSH identity files that require a passphrase.
Volume export improvements. Better handling when exporting to terminal vs file, with clearer output messaging.

Multi-node cluster support. Add and remove nodes from your swarm via CLI (disco nodes:add, disco nodes:remove, disco nodes:list), with proper draining before removal.
Custom disco.json path. Set discoJsonPath in disco.json to point to your actual config file, helpful for monorepos.
Automatic Docker build cache pruning. Build cache is now cleared daily to prevent disk from filling up.
Search in log viewer. Search within deployment and runtime logs in the web dashboard.

Real-time dashboard updates. The dashboard now receives live updates via server-sent events when deployments finish, env vars change, or domains are added.
Stats command. New disco stats command shows CPU, memory, and network usage for all running services.
Service scale persistence. Scale settings are now remembered across deployments instead of resetting to 1.
Better error reporting. Command run failures now include the actual error output instead of generic messages.

Cancel deployments. Stop a running deployment with disco deploy:cancel or from the dashboard.
Deployment hooks. New hook:deploy:start:after runs after the service starts but before traffic is routed.
Postgres version selection. Specify which Postgres version to use when creating instances with --version.
Deployment number env var. DISCO_DEPLOYMENT_NUMBER is now available in your service environment.

List servers. New disco discos:list command shows all configured Disco servers.
Custom SSH identity file. Specify which SSH key to use during init with --identity-file.
Async deployment flow. Deployments are now fully async internally, improving reliability under load.

JWT authentication. The API now supports JWT Bearer tokens in addition to API keys.
CORS configuration. Set allowed origins for cross-origin requests to the API.

Easy mode. Simpler disco.json format that auto-detects your framework and generates the Dockerfile, just set type: easy and optionally a build command.

SSH tunnels. Access internal Postgres securely via disco postgres:tunnel.
Cloudflare Tunnel support. Run Disco behind a Cloudflare Tunnel with disco init --cloudflare-tunnel.
.env as build secret. Environment variables are now available during Docker builds as a secret at /run/secrets/.env.
Generator services. New service type that runs once during deployment to generate static files.
Branch tracking. Projects can now track a specific branch instead of always deploying the default branch.

Postgres addon. Managed Postgres with disco postgres:addon:install, including database creation, user management, and per-project attachment.
Domain management API. Add, remove, and list domains programmatically via the API and CLI.
GitHub Apps integration. Connect repos via GitHub Apps instead of deploy keys for better security and easier setup.
Volume scoping. Volumes are now scoped to projects, preventing accidental cross-project access.
API key usage tracking. See when each API key was last used to help identify unused keys.

Cron jobs. Schedule recurring tasks in disco.json with standard cron syntax, replacing the need for a separate worker.
API key invites. Generate invite links to let teammates add their own API keys without sharing credentials.
Volume import/export. Move data between servers with disco volumes:export and disco volumes:import.
GitHub webhook secrets. Webhook signatures are now verified to prevent unauthorized deployment triggers.
Flexible init command. Rewritten disco init supports Raspberry Pi, AWS EC2, and custom SSH configurations.

Static site support. Deploy static sites with automatic builds via type: static in disco.json.
Node scaling. Scale services across multiple nodes with disco scale:set.
Docker registry support. Push images to a private registry for multi-node deployments.
Pre-deploy hooks. Run commands before deployment starts with hook:deploy:start:before.
Better deployment output. Live streaming of build logs with clearer error messages when services fail to start.

Run commands. Execute one-off commands in your project’s container with disco run.
Project deletion. Remove projects cleanly, including their containers, networks, and Caddy config.
FastAPI migration. Rewrote the daemon from Pyramid to FastAPI for better async support and performance.
Server-sent events for logs. Replaced websockets with SSE for more reliable log streaming.
Build output streaming. Deployment logs now stream in real-time instead of appearing all at once.

Initial release. Core deployment engine with Docker Swarm, Caddy reverse proxy, and GitHub webhooks.
Multi-service projects. Run multiple services (web, worker, etc.) from a single disco.json.
Volumes. Persistent storage that survives deployments, with attach/detach support.
Environment variables. Set and manage env vars per project via the API.
Log streaming. Tail logs from any service with filtering by project and service name.
External syslog. Forward container logs to external syslog servers for aggregation.
