The docker agent binaries built in the Dockerfile were missing version
information in their ldflags, causing them to always report v4.30.0
(the hardcoded default). This created an update loop where agents would
continuously download and restart when checking for updates.
The server's /api/agent/version endpoint returns dockeragent.Version,
which for the bundled binaries was always v4.30.0 instead of the actual
release version (e.g., v4.25.0). When an older agent (e.g., v4.23.0)
checked for updates, it would see v4.30.0 available, download it, restart,
and repeat the cycle continuously.
This fix adds the VERSION file content to the ldflags when building
all docker agent binaries (amd64, arm64, armv7), matching the pattern
already used in scripts/build-release.sh.

This addresses multiple temperature monitoring issues:
1. Fix single-node Proxmox installation failure: Add '|| true' to pvecm status
calls to prevent script exit on standalone (non-clustered) nodes with
'set -euo pipefail'. The script now properly falls through to standalone
node configuration when cluster detection fails.
2. Build pulse-sensor-proxy for all Linux architectures (amd64, arm64, armv7)
in Dockerfile to ensure binaries are available for download on all supported
platforms. This resolves the missing binary issue from v4.23.0.
Note: AMD Tctl sensor support was already implemented in a previous commit.
- Build host agent binaries for all platforms (linux/darwin/windows, amd64/arm64/armv7) in Docker
- Add Makefile target for building agent binaries locally
- Add startup validation to check for missing agent binaries
- Improve download endpoint error messages with troubleshooting guidance
- Enhance host details drawer layout with better organization and visual hierarchy
- Update base images to rolling versions (node:20-alpine, golang:1.24-alpine, alpine:3.20)
- Changed SSH key generation from RSA 2048 to Ed25519 (more secure, faster, smaller)
- Added openssh-client package to Docker image (required for temperature monitoring)
- Updated SSH config template to use id_ed25519
- Removed unused crypto/rsa and crypto/x509 imports
Ed25519 provides better security with shorter keys and faster operations
compared to RSA. The container now has SSH client tools needed to connect
to Proxmox nodes for temperature data collection.
The router's handleDownloadAgent searches for /opt/pulse/bin/pulse-docker-agent
as a fallback when arch-specific binaries are not found or requested. In v4.23.0,
this fallback binary was missing from the Docker image, causing 404 errors for
linux-amd64 downloads.
The Dockerfile now explicitly copies the fallback binary to /opt/pulse/bin/pulse-docker-agent
alongside the arch-specific binaries (linux-amd64, linux-arm64, linux-armv7).
Verified with local build - all four binaries now exist in /opt/pulse/bin/.
Addresses #528
When Pulse runs in Docker, ARM users couldn't download the docker-agent
because only the host architecture binary was built. The Dockerfile now
builds amd64, arm64, and armv7 binaries and includes them at /opt/pulse/bin/
so the download endpoint can serve all architectures.
