Álvaro Torres Cogollo 8ffdc81970 feat: New --values-tpl flag with limited template support ... Use --values-tpl to dynamically generate values based on previously merged configuration. Templates have access to .Values with basic template functions. This is especially useful when you don't have control over upstream chart templates and want to avoid forking just to add tpl support. Templates are rendered after all other value sources (--values, --set) and have access to the merged .Values context: ```bash helm install myapp ./chart --values-tpl dynamic.yaml.tpl helm install myapp ./chart \ --values base.yaml \ --set environment=production \ --values-tpl computed.yaml.tpl ``` ```yaml region: us-east-1 environment: dev replicas: {{ if eq .Values.environment "production" }}5{{ else }}1{{ end }} resourceTier: {{ .Values.environment | upper }} endpoint: "https://{{ .Values.region }}.example.com" ``` 1. Chart defaults (`values.yaml`) 2. All `--values` files 3. All `--set*` flags 4. All `--values-tpl` files (rendered with access to steps 1-3) **Problem:** Each cluster is in a different AWS region/account, and you need different ECR registries. You want to: - Avoid committing per-cluster files (values-prod-us.yaml, values-prod-eu.yaml, etc.) - Not edit upstream chart templates to add tpl support - Keep ArgoCD unaware of chart-specific paths (image.registry, etc.) **Solution:** Single template file in git, cluster-specific values via ArgoCD: ```yaml image: registry: "{{ .Values.accountId }}.dkr.ecr.{{ .Values.region }}.amazonaws.com" repository: myapp tag: "1.0.0" service: extraEnvironment: # Arbitrary path in values CLUSTER_NAME: "{{ .Values.clusterName }}" ``` ```yaml spec: helm: parameters: - name: clusterName value: prod-us-east - name: region value: us-east-1 - name: accountId value: "123456789" valueTplFiles: - values-custom.yaml.tpl ``` ```yaml spec: helm: parameters: - name: clusterName value: prod-eu-west - name: region value: eu-west-1 - name: accountId value: "987654321" valueTplFiles: - values-custom.yaml.tpl ``` - Access to `.Values` from previous merge steps - Sprig functions: `default`, `upper`, `lower`, `trim`, etc. - Format functions: `toYaml`, `toJson`, `toToml`, `fromYaml`, `fromJson`, `fromToml` - Conditionals: `if`/`else`, `range` - Remote templates: `http://`, `https://`, etc. - `include` (requires chart template context) - `tpl` (requires chart template context) - `lookup` (requires Kubernetes client) Signed-off-by: Álvaro Torres Cogollo <atorrescogollo@gmail.com>		2 weeks ago
