Helm add secrets from another YAML file - kubernetes-helm

Question

I have a credential.yaml as:
key1: value1
key2: value2
...and so on
how do I add these key, values in credential.yaml as secrets? I am able to add secrets defined in Values object by looping over them as follows:
apiVersion: v1
kind: Secret
metadata:
name: {{ include "ocp-auth.fullname" . }}
labels:
{{- include "ocp-auth.labels" . | nindent 4 }}
type: Opaque
data:
{{- range $key,$value := .Values.secrets }}
{{ $key }}: {{ $value | b64enc | quote }}
{{- end }}
but this is not working for credential.yaml

Answer 1

1、If you use the file name as the key and the file content as the value, you can write as follows：
apiVersion: v1
kind: Secret
metadata:
name: {{ include "ocp-auth.fullname" . }}
labels:
{{- include "ocp-auth.labels" . | nindent 4 }}
type: Opaque
data:
{{ (.Files.Glob "data/credential.yaml").AsSecrets | indent 2 }}
Where data/credential.yaml is the path where the yaml file is located.
Result:
apiVersion: v1
data:
credential.yaml: a2V5MTogdmFsdWUxCmtleTI6IHZhbHVlMg==
kind: Secret
metadata:
name: ocp-auth
type: Opaque
Decode:
# echo "a2V5MTogdmFsdWUxCmtleTI6IHZhbHVlMg==" | base64 -D
key1: value1
key2: value2
2、If you need to use each key in the file as an item in data, you can write as follows:
apiVersion: v1
kind: Secret
metadata:
name: {{ include "ocp-auth.fullname" . }}
type: Opaque
data:
{{- range .Files.Lines "data/credential.yaml" }}
{{- range $i, $v := . | split ":" }}
{{- if eq $i "_0" }}
{{ $v }}:
{{- else }}
{{ $v | trim | b64enc }}
{{- end }}
{{- end }}
{{- end }}
Result:
apiVersion: v1
data:
key1: dmFsdWUx
key2: dmFsdWUy
kind: Secret
metadata:
name: ops-auth
type: Opaque
Decode:
# echo "dmFsdWUx" | base64 -D
value1
# echo "dmFsdWUy" | base64 -D
value2
This way of writing has more restrictions and is not recommended.
First, it can only process a single row of data. And second, it assumes that there is only one ':' in this row.
