sub-sub-charts of aliased sub-charts not evaluated correctly #9150
Description
Summary
Given a chart with a subchart child and a sub-sub-chart grandchild
charts/
+ child
+ grandchild
where the sub chart is referenced twice with an alias from the Chart.yaml:
dependencies:
- name: child
alias: foo
version: 1.0.0
- name: child
alias: bar
version: 1.0.0
It is expected that the resources of the grandchild chart are rendered twice with different values specified for the two aliases foo and bar.
SSCCE
To reproduce it fully, run:
mkdir -p parent/charts/child/charts/grandchild/templates
mkdir -p parent/charts/child/templates
echo '
apiVersion: v2
appVersion: 1.0.0
name: grandchild
type: application
version: 1.0.0
' > parent/charts/child/charts/grandchild/Chart.yaml
echo '
apiVersion: v2
appVersion: 1.0.0
name: child
type: application
version: 1.0.0
' > parent/charts/child/Chart.yaml
echo '
apiVersion: v2
appVersion: 1.0.0
name: parent
type: application
version: 1.0.0
dependencies:
- name: child
alias: foo
version: 1.0.0
- name: child
alias: bar
version: 1.0.0
' > parent/Chart.yaml
echo '
apiVersion: v1
kind: ConfigMap
metadata:
name: {{ .Chart.Name }}
data:
{{ toYaml .Values | indent 2}}
' > parent/charts/child/templates/dummy.yaml
echo '
apiVersion: v1
kind: ConfigMap
metadata:
name: {{ .Chart.Name }}-{{ .Values.from }}
data:
{{ toYaml .Values | indent 2}}
' > parent/charts/child/charts/grandchild/templates/dummy.yaml
echo '
foo:
grandchild:
from: foo
bar:
grandchild:
from: bar
' > parent/values.yaml
helm template parent
which prints out:
---
# Source: parent/charts/bar/templates/dummy.yaml
apiVersion: v1
kind: ConfigMap
metadata:
name: bar
data:
global: {}
grandchild:
from: bar
global: {}
---
# Source: parent/charts/child/charts/grandchild/templates/dummy.yaml
apiVersion: v1
kind: ConfigMap
metadata:
name: grandchild-bar
data:
from: bar
global: {}
---
# Source: parent/charts/foo/templates/dummy.yaml
apiVersion: v1
kind: ConfigMap
metadata:
name: foo
data:
global: {}
grandchild:
from: foo
global: {}
What is missing, is the following:
# Source: parent/charts/child/charts/grandchild/templates/dummy.yaml
apiVersion: v1
kind: ConfigMap
metadata:
name: grandchild-foo
data:
from: foo
global: {}
From my understanding of sub-charts and aliases, this is a bug.
