| # File Domain | ||
| The File domain allows for validation of arbitrary file contents. The file domain can evaluate local files and network files. Files are copied to a temporary directory for evaluation and deleted afterwards. | ||
|
|
||
| ## Specification | ||
| The File domain specification accepts a descriptive name for the file as well as it's path. The names must be unique. | ||
|
|
||
| ```yaml | ||
| domain: | ||
| type: file | ||
| file-spec: | ||
| filepaths: | ||
| - name: config | ||
| path: grafana.ini | ||
| ``` | ||
|
|
||
| ## Supported File Types | ||
| The file domain use's OPA's [conftest](https://conftest.dev) to parse files into a json-compatible format for validations. ∑Both OPA and kyverno (using [kyverno-json](https://kyverno.github.io/kyverno-json/latest/)) can validate files parsed by the file domain. | ||
|
|
||
| The file domain supports the following file formats for validation: | ||
| * CUE | ||
| * CycloneDX | ||
| * Dockerfile | ||
| * EDN | ||
| * Environment files (.env) | ||
| * HCL and HCL2 | ||
| * HOCON | ||
| * Ignore files (.gitignore, .dockerignore) | ||
| * INI | ||
| * JSON | ||
| * Jsonnet | ||
| * Property files (.properties) | ||
| * SPDX | ||
| * TextProto (Protocol Buffers) | ||
| * TOML | ||
| * VCL | ||
| * XML | ||
| * YAML | ||
|
|
||
| ## Validations | ||
| When writing validations against files, the filepath Name must be included as the top-level key in the validation, in this example below `check`: | ||
|
|
||
| ```yaml | ||
| metadata: | ||
| name: check-grafana-protocol | ||
| uuid: ad38ef57-99f6-4ac6-862e-e0bc9f55eebe | ||
| domain: | ||
| type: file | ||
| file-spec: | ||
| filepaths: | ||
| - name: 'grafana' | ||
| path: 'custom.ini' | ||
| provider: | ||
| type: kyverno | ||
| kyverno-spec: | ||
| policy: | ||
| apiVersion: json.kyverno.io/v1alpha1 | ||
| kind: ValidatingPolicy | ||
| metadata: | ||
| name: grafana-config | ||
| spec: | ||
| rules: | ||
| - name: protocol-is-https | ||
| assert: | ||
| all: | ||
| - check: | ||
| grafana: | ||
| server: | ||
| protocol: https | ||
| ``` | ||
|
|
||
| ```grafana.ini | ||
| [server] | ||
| # Protocol (http, https, socket) | ||
| protocol = http | ||
| ``` | ||

We don't yet have a good pattern for the mapping of domain -> provider.
That said - I do like the Kyverno example below. Could we add an OPA provider example as well?

I don't think the writing is very good but I added an OPA example! please nitpick freely.
