# Secrets
|
|
|
|
helmfile can handle secrets using [helm-secrets](https://github.com/jkroepke/helm-secrets) plugin or using remote secrets storage
|
|
(everything that package [vals](https://github.com/variantdev/vals) can handle vault, AWS SSM etc)
|
|
This section will describe the second use case.
|
|
|
|
# Remote secrets
|
|
|
|
This paragraph will describe how to use remote secrets storage (vault, SSM etc) in helmfile
|
|
|
|
## Fetching single key
|
|
|
|
To fetch single key from remote secret storage you can use `fetchSecretValue` template function example below
|
|
|
|
```yaml
|
|
# helmfile.yaml
|
|
|
|
repositories:
|
|
- name: stable
|
|
url: https://kubernetes-charts.storage.googleapis.com
|
|
|
|
environments:
|
|
default:
|
|
values:
|
|
- service:
|
|
password: ref+vault://svc/#pass
|
|
login: ref+vault://svc/#login
|
|
releases:
|
|
- name: service
|
|
namespace: default
|
|
labels:
|
|
cluster: services
|
|
secrets: vault
|
|
chart: stable/svc
|
|
version: 0.1.0
|
|
values:
|
|
- service:
|
|
login: {{ .Values.service.login | fetchSecretValue }} # this will resolve ref+vault://svc/#pass and fetch secret from vault
|
|
password: {{ .Values.service.password | fetchSecretValue | quote }}
|
|
# - values/service.yaml.gotmpl # alternatively
|
|
```
|
|
## Fetching multiple keys
|
|
Alternatively you can use `expandSecretRefs` to fetch a map of secrets
|
|
```yaml
|
|
# values/service.yaml.gotmpl
|
|
service:
|
|
{{ .Values.service | expandSecretRefs | toYaml | nindent 2 }}
|
|
```
|
|
|
|
This will produce
|
|
```yaml
|
|
# values/service.yaml
|
|
service:
|
|
login: svc-login # fetched from vault
|
|
password: pass
|
|
|
|
```
|
