This implements the ability for users to assign custom display names to Docker hosts,
similar to the existing functionality for Proxmox nodes. This addresses the issue where
multiple Docker hosts with identical hostnames but different IPs/domains cannot be
easily distinguished in the UI.
Backend changes:
- Add CustomDisplayName field to DockerHost model (internal/models/models.go:201)
- Update UpsertDockerHost to preserve custom display names across updates (internal/models/models.go:1110-1113)
- Add SetDockerHostCustomDisplayName method to State for updating names (internal/models/models.go:1221-1235)
- Add SetDockerHostCustomDisplayName method to Monitor (internal/monitoring/monitor.go:1070-1088)
- Add HandleSetCustomDisplayName API handler (internal/api/docker_agents.go:385-426)
- Route /api/agents/docker/hosts/{id}/display-name PUT requests (internal/api/docker_agents.go:117-120)
Frontend changes:
- Add customDisplayName field to DockerHost TypeScript interface (frontend-modern/src/types/api.ts:136)
- Add MonitoringAPI.setDockerHostDisplayName method (frontend-modern/src/api/monitoring.ts:151-187)
- Update getDisplayName function to prioritize custom names (frontend-modern/src/components/Settings/DockerAgents.tsx:84-89)
- Add inline editing UI with save/cancel buttons in Docker Agents settings (frontend-modern/src/components/Settings/DockerAgents.tsx:1349-1413)
- Update sorting to use custom display names (frontend-modern/src/components/Docker/DockerHosts.tsx:58-59)
- Update DockerHostSummaryTable to display custom names (frontend-modern/src/components/Docker/DockerHostSummaryTable.tsx:40-42, 87, 120, 254)
Users can now click the edit icon next to any Docker host name in Settings > Docker Agents
to set a custom display name. The custom name will be preserved across agent reconnections
and takes priority over the hostname reported by the agent.
