# This is an Argo CD "Application" — not a Kubernetes-native concept, but a
|
||
|
|
# Custom Resource that Argo CD adds to the cluster (see docs/glossary.md:
|
||
|
|
# "CRD"). It tells Argo CD: "watch this path in this Git repo, and keep the
|
||
|
|
# cluster's demo namespace matching whatever you find there."
|
||
|
|
#
|
||
|
|
# You never apply this file yourself. The app-of-apps
|
||
|
|
# (argocd/app-of-apps/app-of-apps.yaml) watches this apps/ directory, and
|
||
|
|
# Argo CD applies every Application it finds here automatically — including
|
||
|
|
# this one. That's the whole "app-of-apps" trick: one Application manages a
|
||
|
|
# folder of other Applications.
|
||
|
|
#
|
||
|
|
# --- Manifest-based vs. Helm-based apps ---
|
||
|
|
# This app points at a plain folder of Kubernetes manifests (apps/demo/).
|
||
|
|
# An app can instead point at a Helm chart — including an umbrella chart
|
||
|
|
# whose Chart.yaml declares a `dependencies:` entry on a third-party chart
|
||
|
|
# (e.g. a database or ingress controller from a public chart repo). Argo CD
|
||
|
|
# detects a Helm chart automatically when it finds a Chart.yaml at the
|
||
|
|
# source path, resolves its dependencies, and syncs the rendered output just
|
||
|
|
# like any other app. See docs/07-adding-new-apps.md for a worked example —
|
||
|
|
# the demo app deliberately stays plain manifests so the GitOps loop is easy
|
||
|
|
# to read end to end with no templating in the way.
