I can generate the ConfigMap
from the directory but they are not translating the template directives or values. Below is an example of the Release.Namespace
template directive not being output in the ConfigMap
.
.
|____Chart.yaml
|____charts
|____.helmignore
|____templates
| |____my-scripts.yaml
|____values.yaml
|____test-files
|____test1.txt
---
# templates/myscripts.yaml
apiVersion: v1
kind: ConfigMap
metadata:
name: my-scripts
namespace: {{ .Release.Namespace }}
data:
test.txt: |-
{{ .Files.Get "test-files/test1.txt" | indent 4}}
# test-files/test1.txt
test file
{{ .Release.Namespace }}
When I run helm install . --dry-run --debug --namespace this-should-print
here's what I'm getting vs what I'm expecting:
Actual:
---
# Source: test/templates/my-scripts.yaml
# templates/myscripts.yaml
apiVersion: v1
kind: ConfigMap
metadata:
name: my-scripts
namespace: test
data:
test.txt: |-
# test-files/test1.txt
test file
{{ .Release.Namespace }}
Expected:
---
# Source: test/templates/my-scripts.yaml
# templates/myscripts.yaml
apiVersion: v1
kind: ConfigMap
metadata:
name: my-scripts
namespace: test
data:
test.txt: |-
# test-files/test1.txt
test file
this-should-print
Alternatively, I would be interested in every file in a specified directory being output in the format like:
<filename>: |-
<content>
I've found a way of doing it using the tpl function:
---
# templates/myscripts.yaml
apiVersion: v1
kind: ConfigMap
metadata:
name: my-scripts
namespace: {{ .Release.Namespace }}
data:
test.txt: |-
{{ tpl ( .Files.Get "test-files/test1.txt" ) . | indent 4 }}
The new output is exactly as expected:
# templates/myscripts.yaml
apiVersion: v1
kind: ConfigMap
metadata:
name: my-scripts
namespace: this-should-print
data:
test.txt: |-
# test-files/test1.txt
test file
this-should-print
And for bonus points, getting all files from a directory without having to update this list within the config map:
---
# templates/myscripts.yaml
apiVersion: v1
kind: ConfigMap
metadata:
name: my-scripts
namespace: {{ .Release.Namespace }}
data:
{{ tpl (.Files.Glob "groovy-scripts/*").AsConfig . | indent 4 }}
