Short: "start a plugin.proto worker process",

|
Long: `Start an external plugin worker using weed/pb/plugin.proto over gRPC.
|
|
|
|
This command provides plugin job type handlers for cluster maintenance,
|
|
including descriptor delivery, heartbeat/load reporting, detection, and execution.
|
|
|
|
Behavior:
|
|
- Use -jobType to choose handlers by category or explicit name (comma-separated)
|
|
- Categories: "all" (every registered handler), "default" (lightweight jobs),
|
|
"heavy" (resource-intensive jobs like erasure coding)
|
|
- Explicit job type names and aliases are still supported (e.g. "vacuum", "ec")
|
|
- Categories and explicit names can be mixed (e.g. "default,iceberg")
|
|
- Use -workingDir to persist worker.id for stable worker identity across restarts
|
|
- Use -metricsPort/-metricsIp to expose /health, /ready, and /metrics
|
|
|
|
Examples:
|
|
weed worker -admin=localhost:23646
|
|
weed worker -admin=localhost:23646 -jobType=all
|
|
weed worker -admin=localhost:23646 -jobType=default
|
|
weed worker -admin=localhost:23646 -jobType=heavy
|
|
weed worker -admin=localhost:23646 -jobType=default,iceberg
|
|
weed worker -admin=localhost:23646 -jobType=vacuum,volume_balance
|
|
weed worker -admin=localhost:23646 -jobType=erasure_coding
|
|
weed worker -admin=admin.example.com:23646 -id=plugin-vacuum-a -heartbeat=10s
|
|
weed worker -admin=localhost:23646 -workingDir=/var/lib/seaweedfs-plugin
|
|
weed worker -admin=localhost:23646 -metricsPort=9327 -metricsIp=0.0.0.0
