# kosli attest artifact

> Attest an artifact creation to a Kosli flow.  

## Synopsis

```shell theme={"theme":"dracula","languages":{"custom":["/languages/rego.json"]}}
kosli attest artifact {IMAGE-NAME | FILE-PATH | DIR-PATH} [flags]
```

Attest an artifact creation to a Kosli flow.

The artifact fingerprint can be provided directly with the `--fingerprint` flag, or
calculated based on `--artifact-type` flag.

Artifact type can be one of: "file" for files, "dir" for directories, "oci" for container
images in registries or "docker" for local docker images.

Note: `--artifact-type=docker` reads the image's repo digest via the local Docker daemon.
The image must have been pushed to or pulled from a registry for a repo digest to exist;
a freshly built image (just `docker build`) will not have one. If the image is already in
a registry, prefer `--artifact-type=oci`, which fetches the digest directly from the
registry without needing a local Docker daemon.

For `--artifact-type=oci` (and for `--artifact-type=docker` when `--registry-username`
is set), registry credentials are resolved as follows:

1. If `--registry-username` (and optionally `--registry-password`) is set, it is used directly.
2. Otherwise, credentials are discovered automatically from:
   * the Docker config file (`~/.docker/config.json`, populated by `docker login`)
   * the Podman/containers auth file (`~/.config/containers/auth.json`, or `$REGISTRY_AUTH_FILE`)
   * any Docker credential helper configured in that config (e.g. `docker-credential-ecr-login`
     for AWS ECR, `docker-credential-gcloud` for GCR/Artifact Registry, an ACR helper for Azure,
     or a local keychain helper), invoked as an external binary on `$PATH`
   * if none of the above yield credentials, the registry is accessed anonymously, which works
     for public images
     `--registry-provider` is deprecated and no longer used.

To specify paths in a directory artifact that should always be excluded from the SHA256 calculation, you can add a `.kosli_ignore` file to the root of the artifact.
Each line should specify a relative path or path glob to be ignored. You can include comments in this file, using `#`.
The `.kosli_ignore` will be treated as part of the artifact like any other file, unless it is explicitly ignored itself.
This command requires access to a git repo to associate the artifact to the git commit it is originating from.
You can optionally redact some of the git commit data sent to Kosli using `--redact-commit-info`.
To record repository information, all three of `--repo-id`, `--repo-url`, and `--repository` must be set together.
These are automatically set in GitHub Actions, GitLab CI, Bitbucket Pipelines, and Azure DevOps.
In other CI systems, set them explicitly to capture repository metadata.
