SLICE-03 (devops-engineer): ported from coreci/scripts/proxmox/: api.sh (verbatim), ct-exists.sh, lxc-clone.sh (4GB/16GB, hostname=praxis), lxc-config.sh (praxis env vars, praxis-firstboot.sh snippet), lxc-start.sh, stage-snippet.sh (G-101 FIX: bakes GITEA_TOKEN into snippet via sed), timing.sh (verbatim), rollback.sh (proxy code removed) SLICE-04 (devops-engineer): health-check.sh adapted for /health:8789 (G-104 FIX: timeout bumped 300s→600s for Docker build margin) REQ-DEPLOY-03, 04, 05, 07, 08 covered. ---ci--- project: praxis phase: 1 milestone: v0.2 status: execute slice: 03-04 wave: 2 ---/ci---

# CoreCI — deploy-stage timing helper (P11 — IDEATE-39).
|
|
#
|
|
# Sourced (not executed) by the deploy orchestrators
|
|
# (proxy-deploy.sh, lxc-deploy.sh) to emit structured slog-style
|
|
# JSON timing lines for each deploy stage to stderr, where a log
|
|
# aggregator (or `2>>timing.log`) can pick them up.
|
|
#
|
|
# Usage:
|
|
# . /path/to/timing.sh
|
|
# timing_start clone
|
|
# ... clone work ...
|
|
# timing_end clone
|
|
#
|
|
# Emits one JSON line per timing_end to stderr:
|
|
# {"event":"deploy_timing","stage":"clone","duration_s":3}
|
|
#
|
|
# Optional node_exporter textfile collector: if the env var
|
|
# NODE_TEXTFILE_COLLECTOR_DIR points to a writable directory, the
|
|
# latest per-stage duration is ALSO written there as
|
|
# `coreci_deploy_timing_<stage>.prom` so a node_exporter textfile
|
|
# collector scrapes it. If the dir is unset or unwritable, only the
|
|
# JSON log is emitted (the structured-log-first decision, PLAN v3.6
|
|
# P11 Wave 2).
|
|
#
|
|
# Dependencies: date (POSIX epoch via +%s). jq is NOT required (the
|
|
# JSON line is constructed with printf so there is no external dep
|
|
# on the slow path). Idempotent: re-sourcing is harmless (the
|
|
# _TIMING_STARTS associative state is reset on source, but the
|
|
# orchestrator sources exactly once at startup).
|
|
#
|
|
# NOTE: Ported verbatim from coreci. The metric/prefix names retain
|
|
# the `coreci_` origin identifier for compatibility with existing
|
|
# node_exporter dashboards; rename in a follow-up if desired.
|
|
#
|
|
# shellcheck shell=sh
|
|
|
|
# _TIMING_STARTS is a flat file-backed map (stage → epoch seconds).
|
|
# POSIX sh has no associative arrays, so we use a single newline-
|
|
# separated string of "stage=epoch" records and scan it. Stages are
|
|
# short identifiers (clone/config/start/health/smoke) so the linear

|
# scan is trivially cheap.
