Docker agent installed on Raspberry Pi 3B with install script gives Exec format error

[ultimateguy]

I installed the Pulse Docker Agent on my Docker host (Raspberry Pi 3B+) using the install script. Installation reports as successful, however the agent exits with code 203. The logs show:

Nov 03 12:38:24 raspberrypi systemd[1028605]: pulse-docker-agent.service: Failed to execute /usr/local/bin/pulse-docker-agent: Exec format error Nov 03 12:38:24 raspberrypi systemd[1028605]: pulse-docker-agent.service: Failed at step EXEC spawning /usr/local/bin/pulse-docker-agent: Exec format error Nov 03 12:38:24 raspberrypi systemd[1]: pulse-docker-agent.service: Main process exited, code=exited, status=203/EXEC Nov 03 12:38:24 raspberrypi systemd[1]: pulse-docker-agent.service: Failed with result 'exit-code'.

I imagine this means the binary is the wrong architecture? Not sure why the script couldn't handle this.

Fixed in d76d05c.

The issue was that development builds were missing the architecture-specific docker agent binaries. The Makefile's build-agents target only built host agents, not docker agents.

What was happening:

1. Install script detected Raspberry Pi 3B+ as armv7l → requested linux-armv7 binary
2. Download endpoint couldn't find pulse-docker-agent-linux-armv7
3. Fell back to default pulse-docker-agent which was x86-64
4. ARM system couldn't execute x86-64 binary → "Exec format error"

The fix:

• Added docker agent builds to Makefile (commit 441659f)
• Built missing binaries for all architectures (amd64, arm64, armv7)
• Download endpoint now serves correct ARM v7 binary

The install script should now work correctly on Raspberry Pi 3B+ and other ARM v7 devices. The binaries are already deployed and available.
