# bootstrap.sh — the SINGLE Flux + SOPS bootstrap entrypoint for the dev cluster.
|
|
#
|

# Phase 1, T-1.4 · ADR-0004 (Flux) · ADR-0007 (SOPS+age) · R-GITOPS-01 · R-SEC-01.

# =============================================================================
|

# *** AUTHORED, NOT RUN. The Infra worker's FINAL Ansible play invokes this ***

# *** (interface contract, see ../README.md). Agents must not execute it. ***

# =============================================================================

#
|
|
# WHAT THIS DOES (Phase 1, bootstrap-source method — reconciles from the LOCAL repo, no remote
|
|
# git host exists yet per spec docs/05 + CONTRIBUTING.md):
|
|
#
|
|
# 1. `flux install` — deploy the Flux controllers. Besides the default set (source, kustomize,
|
|
# helm, notification) we ALSO install the two IMAGE controllers via
|
|
# `--components-extra` (see FLUX_COMPONENTS_EXTRA below): image-reflector-
|
|
# controller + image-automation-controller. These register the
|
|
# image.toolkit.fluxcd.io CRDs (ImageRepository/ImagePolicy/ImageUpdateAutomation)
|
|
# that Phase-4 hands-off updates need (ADR-0009, R-UPD-02). They are part of the
|
|
# flux-system install exactly like the other 4 controllers — NOT a reconciled
|
|
# HelmRelease — so their CRDs pre-exist before the first reconcile (this is why
|
|
# platform/image-automation can carry the ImageUpdateAutomation CR without the
|
|
# F-MON1 controllers/configs split: the CRD is present at bootstrap, like
|
|
# GitRepository/Kustomization are). WS-UPDATE (T-4.5).
|
|
# We do NOT use `flux bootstrap git` in Phase 1 because that command commits
|
|
# and OWNS its own gotk-sync GitRepository+Kustomization named `flux-system`.
|
|
# Our entrypoints are ALREADY authored in clusters/base (flux-system.yaml =
|
|
# the GitRepository; platform.yaml/apps.yaml = the Kustomizations). Letting
|
|
# bootstrap regenerate them would DUPLICATE/conflict. `flux install` +
|
|
# applying the authored clusters/dev overlay is the reconciling path.
|
|
# 2. sops-age Secret — the operator installs the age PRIVATE key out-of-band BEFORE reconcile so
|
|
# decryption works on first pass (../sops/age-key-secret.md). This script
|
|
# only VERIFIES it exists; it never handles key material.
|
|
# 3. `kubectl apply -k clusters/dev` — materialises the authored reconciliation graph:
|
|
# GitRepository `flux-system` (source) -> Kustomization `platform` ->
|
|
# Kustomization `apps` (dependsOn platform), with cluster-vars overlay
|
|
# (R-ENV-02) and SOPS decryption enabled via the patches in ./patches/.
|
|
#
|
|
# PREREQUISITES the operator/PM resolves before this runs (see ../README.md "Handoff"):
|
|
# - clusters/base/flux-system.yaml url placeholder is overridden — wire ./patches/flux-system-
|
|
# source-url.yaml into clusters/dev/kustomization.yaml (or set the URL) so the source is real.
|
|
# - ./patches/platform-sops-decryption.yaml + apps-sops-decryption.yaml are wired into
|
|
# clusters/dev/kustomization.yaml `patches:` so decryption is enabled at reconcile.
|
|
# - the repo-root .sops.yaml carries the real age recipient (single canonical file; no copy under ../sops).
|
|
#
|
|
# PHASE 6 (WS-GITOPS, later — NOT Phase 1): once Gitea is up, cut the source over with
|
|
# `flux bootstrap git` against gitea.home.keithjackson.dev — see ../README.md "Phase-6 cutover".
