When called with an empty array, `docker service ps` receives no
SERVICE argument and fails with "requires at least 1 argument".
Return early with [] when appNames is empty.
getSwarmNodes was changed to return [] on error, but the existing
SwarmMonitorCard checks `if (!nodes)` to detect failures. Since ![]
is false, the error state was silently skipped, breaking the Overview
tab for users without Docker Swarm initialized.
Reverted to return undefined on error (original behavior) so the
existing Overview tab error handling continues to work. The Containers
tab already handles nodes === undefined explicitly.
TL;DR: New "Containers" tab on the Swarm page showing which containers
run on which nodes, with live CPU/Memory/Block I/O/Network I/O metrics
refreshing every 5 seconds. Comprehensive edge case handling guides
users through prerequisites (swarm init, registry, service deployment).

## New Files
- `apps/dokploy/components/dashboard/swarm/containers/show-swarm-containers.tsx`
Main component: data fetching, error/empty states, summary cards,
and the node-grouped container layout.
- `apps/dokploy/components/dashboard/swarm/containers/node-section.tsx`
Collapsible per-node section with container table, role badge,
and down-node indicator.
- `apps/dokploy/components/dashboard/swarm/containers/container-row.tsx`
Table row for a single container: state badge with error tooltip,
formatted CPU/memory/IO metrics.
- `apps/dokploy/components/dashboard/swarm/containers/utils.ts`
Formatting helpers for docker stats values (CPU %, memory, I/O).
- `apps/dokploy/components/dashboard/swarm/containers/types.ts`
Shared TypeScript interfaces (ContainerStat, ContainerInfo, SwarmNode,
NodeGroup).
## Modified Files
- `apps/dokploy/pages/dashboard/swarm.tsx`
Added Tabs (Overview / Containers) wrapping existing SwarmMonitorCard
and the new ShowSwarmContainers component.
- `apps/dokploy/server/api/routers/swarm.ts`
Added `getContainerStats` tRPC endpoint calling `getAllContainerStats`,
following existing auth/validation patterns.
- `packages/server/src/services/docker.ts`
- Added `getAllContainerStats()` — runs `docker stats --no-stream` for
cluster-wide container metrics.
- Fixed `getSwarmNodes`, `getNodeApplications`, `getApplicationInfo` to
return `[]` instead of `undefined` on errors (prevents tRPC
serialization crashes) and added `console.error` logging.
- Added empty stdout guard (`if (!stdout.trim()) return []`) to prevent
`JSON.parse("")` crashes when no services exist.
## Features
- Container table per node: name, image, state, CPU %, memory usage,
block I/O, and network I/O
- Resource formatting: values rounded to 1 decimal (2.711MiB → 2.7 MiB),
CPU to 1 decimal (0.00% → 0.0%)
- Node role badges (Leader / Reachable / Worker) on each section header
- Error tooltips: hover the status badge to see Docker error details
- Down/drained node detection with red indicator dot and warning banner
- Multi-node metrics banner explaining docker stats manager-only limitation
- Unscheduled services footer for services scaled to 0 replicas
- Contextual empty/error states with actionable guidance, doc links to
Dokploy docs and Docker Swarm guide, and links to Cluster Settings
## Edge Cases Handled
1. Swarm not initialized (tRPC error or undefined data)
2. Docker command failures (stderr / non-zero exit)
3. Swarm active but no services deployed
4. Services exist but no running containers
5. Containers with Docker errors (shown in tooltip + error alert)
6. Nodes down or drained (cross-referenced from node list)
7. Multi-node setups (metrics only from manager node)
8. Services scaled to 0 replicas (separated from running containers)
9. Empty stdout from docker commands (no JSON.parse crash)
- Eliminated the getDokployImage and pullLatestRelease functions to streamline the settings service.
- Updated the code to focus on dynamic image retrieval, enhancing clarity and maintainability.
- Added logic to retrieve and delete SSO providers, ensuring proper permission checks and error handling.
- Updated user trusted origins when adding or removing SSO providers, maintaining accurate origin lists.
- Refactored trusted origins retrieval to improve clarity and efficiency in the authentication process.
- Introduced utility functions for normalizing trusted origins and converting request headers.
- Added a new service to fetch SSO providers from the database, including relevant fields such as id, providerId, issuer, domain, oidcConfig, and samlConfig.
- This functionality will support future enhancements in SSO integration.
- Introduced a new notification type "resend" to the system.
- Added database schema for resend notifications including fields for apiKey, fromAddress, and toAddress.
- Implemented functions to create, update, and send resend notifications.
- Updated notification router to handle resend notifications with appropriate API endpoints.
- Enhanced existing notification services to support sending notifications via the Resend service.
- Modified various notification utilities to accommodate the new resend functionality.
- Added logic to getUpdateData to compare current and latest image digests for canary and feature tags, indicating if an update is available.
- Updated reloadDockerResource to ensure the correct image tag is used during dokploy service updates based on the current image tag.
- Updated the reloadDockerResource function to include an optional version parameter.
- Modified the command for updating the dokploy service to specify the image version during updates.
- Updated Next.js version in both root and dokploy package.json files to 16.0.10 for improved performance and features.
- Removed the turbopack development script from the dokploy package.json to streamline the development process.
- Added volumeBackup property to notification handling in multiple files for enhanced backup options.
- Added `isDefault` boolean column to the environment schema, defaulting to false.
- Updated environment creation and deletion logic to handle default environments, allowing the production environment to be created and renamed.
- Enhanced error handling for environment updates and deletions to prevent modifications to default environments.
- Updated UI components to reflect changes in environment selection based on the new default logic.
- Removed try-catch block in the rollback function to streamline error handling, allowing for direct propagation of errors from the rollbackApplication call.
- This change enhances code readability and maintains the functionality of the rollback process.
- Updated the deployPreviewApplication function to await the getBuildCommand call, ensuring the command is fully constructed before execution.
- This change improves the reliability of the deployment process by handling asynchronous command generation correctly.
- Added a new optional field `rollbackRegistryId` to the application schema to support rollback registry selection.
- Enhanced the form in the ShowRollbackSettings component to include a dropdown for selecting a rollback registry when rollbacks are enabled.
- Updated the application service to handle rollback registry logic during deployment and rollback processes.
- Improved error handling and validation for rollback settings, ensuring a registry is selected when rollbacks are active.
- Adjusted database schema and migration files to accommodate the new rollback registry feature.
