CI run 522 dagger job failed with `go.mod requires go >= 1.26.2 (running go 1.25.9; GOTOOLCHAIN=local)`. golang:1.25-alpine3.22 was a holdover from the original Dockerfile; alloy v1.16.0's go.mod requires Go 1.26. Switching to golang:alpine3.23 (currently Go 1.26.2) — matches both alloy's toolchain requirement and the go_build helper's image choice.

"""Grafana Alloy — telemetry collector, native Dagger build.
|
|
|
|
Three-stage build: Node (UI), Go (server via upstream Makefile with embedded
|
|
UI assets), Alpine (runtime). Source cloned from forge mirror.
|
|
|
|
Notes:
|
|
- Builds via `make alloy` rather than plain `go build` so version stamping,
|
|
release flags, and the netgo+embedalloyui tags match upstream releases.
|
|
- promtail_journal_enabled is intentionally omitted: it requires
|
|
libsystemd-dev and our k8s deployments read pod logs from the filesystem,
|
|
not journald.
|
|
- Uses golang:alpine3.23 (currently Go 1.26.2 — matches alloy v1.16.0's
|
|
go.mod toolchain requirement and the go_build helper's image choice).
