# 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.
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.
## Flags
| Flag | Description |
| :-------------------------------------- | :---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `--annotate` stringToString | \[optional] Annotate the attestation with data using key=value. |
| `-t`, `--artifact-type` string | The type of the artifact to calculate its SHA256 fingerprint. One of: \[oci, docker, file, dir]. Only required if you want Kosli to calculate the fingerprint for you (i.e. when you don't specify '`--fingerprint`' on commands that allow it). |
| `-b`, `--build-url` string | The url of CI pipeline that built the artifact. (defaulted in some CIs: [docs](/integrations/ci_cd) ). |
| `-g`, `--commit` string | \[defaulted] The git commit from which the artifact was created. (defaulted in some CIs: [docs](/integrations/ci_cd), otherwise defaults to HEAD ). (default "HEAD") |
| `-u`, `--commit-url` string | The url for the git commit that created the artifact. (defaulted in some CIs: [docs](/integrations/ci_cd) ). |
| `-N`, `--display-name` string | \[optional] Artifact display name, if different from file, image or directory name. |
| `-D`, `--dry-run` | \[optional] Run in dry-run mode. When enabled, no data is sent to Kosli and the CLI exits with 0 exit code regardless of any errors. |
| `-x`, `--exclude` strings | \[optional] The comma separated list of directories and files to exclude from fingerprinting. Can take glob patterns. Only applicable for `--artifact-type` dir. |
| `--external-fingerprint` stringToString | \[optional] A SHA256 fingerprint of an external attachment represented by `--external-url`. The format is label=fingerprint (labels cannot contain '.' or '='). This flag can be set multiple times. There must be an external url with a matching label for each external fingerprint. |
| `--external-url` stringToString | \[optional] Add labeled reference URL for an external resource. The format is label=url (labels cannot contain '.' or '='). This flag can be set multiple times. If the resource is a file or dir, you can optionally add its fingerprint via `--external-fingerprint` |
| `-F`, `--fingerprint` string | \[conditional] The SHA256 fingerprint of the artifact. Only required if you don't specify '`--artifact-type`'. |
| `-f`, `--flow` string | The Kosli flow name. |
| `-h`, `--help` | help for artifact |
| `-n`, `--name` string | The name of the artifact in the yml template file. |
| `--redact-commit-info` strings | \[optional] The list of commit info to be redacted before sending to Kosli. Allowed values are one or more of \[author, message, branch]. |
| `--registry-password` string | \[conditional] The container registry password or access token. Only required if you want to read container image SHA256 digest from a remote container registry. |
| `--registry-username` string | \[conditional] The container registry username. Only required if you want to read container image SHA256 digest from a remote container registry. |
| `--repo-id` string | \[conditional] The stable, unique identifier for the repository in your VCS provider (e.g. a numeric ID). Do not use the repository name as it can change if the repo is renamed. All three of `--repo-id`, `--repo-url` and `--repository` must be set to record repository information (defaulted in some CIs: [docs](/integrations/ci_cd) ). |
| `--repo-provider` string | \[optional] The source code hosting provider. One of: github, gitlab, bitbucket, azure-devops (defaulted in some CIs: [docs](/integrations/ci_cd) ). |
| `--repo-root` string | \[defaulted] The directory where the source git repository is available. (default ".") |
| `--repo-url` string | \[conditional] The URL of the repository. Must be a valid URL. All three of `--repo-id`, `--repo-url` and `--repository` must be set to record repository information (defaulted in some CIs: [docs](/integrations/ci_cd) ). |
| `--repository` string | \[conditional] The name of the repository (e.g. owner/repo-name). All three of `--repo-id`, `--repo-url` and `--repository` must be set to record repository information (defaulted in some CIs: [docs](/integrations/ci_cd) ). |
| `-T`, `--trail` string | The Kosli trail name. |
## Flags inherited from parent commands
| Flag | Description |
| :---------------------------- | :------------------------------------------------------------------------------------------------------------------------------------------------------ |
| `-a`, `--api-token` string | The Kosli API token. |
| `-c`, `--config-file` string | \[optional] The Kosli config file path. (default "kosli") |
| `--debug` | \[optional] Print debug logs to stdout. |
| `-H`, `--host` string | \[defaulted] The Kosli endpoint. (default "[https://app.kosli.com](https://app.kosli.com)") |
| `--http-proxy` string | \[optional] The HTTP proxy URL including protocol and port number. e.g. `http://proxy-server-ip:proxy-port` |
| `-r`, `--max-api-retries` int | \[defaulted] How many times should API calls be retried when the API host is not reachable. (default 3) |
| `--org` string | The Kosli organization. |
| `-q`, `--quiet` | \[optional] Suppress non-critical warning messages. Errors and normal output are not affected. If both `--quiet` and `--debug` are set, `--debug` wins. |
