| Attribute | Type | Description | Examples | [Requirement Level](https://opentelemetry.io/docs/specs/semconv/general/attribute-requirement-level/) | Stability |
|
|
|---|---|---|---|---|---|
|
|
| [`container.id`](/docs/registry/attributes/container.md) | string | Container ID. Usually a UUID, as for example used to [identify Docker containers](https://docs.docker.com/engine/containers/run/#container-identification). The UUID might be abbreviated. | `a3bf90e006b2` | `Recommended` |  |
|
|
| [`container.label.<key>`](/docs/registry/attributes/container.md) | string | Container labels, `<key>` being the label name, the value being the label value. [1] | `nginx` | `Recommended` |  |
|
|
| [`container.name`](/docs/registry/attributes/container.md) | string | Container name used by container runtime. | `opentelemetry-autoconf` | `Recommended` |  |
|
|
| [`oci.manifest.digest`](/docs/registry/attributes/oci.md) | string | The digest of the OCI image manifest. For container images specifically is the digest by which the container image is known. [2] | `sha256:e4ca62c0d62f3e886e684806dfe9d4e0cda60d54986898173c1083856cfda0f4` | `Recommended` |  |
|
|
| [`container.command`](/docs/registry/attributes/container.md) | string | The command used to run the container (i.e. the command name). [3] | `otelcontribcol` | `Opt-In` |  |
|
|
| [`container.command_args`](/docs/registry/attributes/container.md) | string[] | All the command arguments (including the command/executable itself) run by the container. | `["otelcontribcol", "--config", "config.yaml"]` | `Opt-In` |  |
|
|
| [`container.command_line`](/docs/registry/attributes/container.md) | string | The full command run by the container as a single string representing the full command. | `otelcontribcol --config config.yaml` | `Opt-In` |  |
|
|
|
|
**[1] `container.label.<key>`:** For example, a docker container label `app` with value `nginx` SHOULD be recorded as the `container.label.app` attribute with value `"nginx"`.
|
|
|
|
**[2] `oci.manifest.digest`:** Follows [OCI Image Manifest Specification](https://github.com/opencontainers/image-spec/blob/main/manifest.md), and specifically the [Digest property](https://github.com/opencontainers/image-spec/blob/main/descriptor.md#digests).
|
|
An example can be found in [Example Image Manifest](https://github.com/opencontainers/image-spec/blob/main/manifest.md#example-image-manifest).
|
|
|
|
**[3] `container.command`:** If using embedded credentials or sensitive data, it is recommended to remove them to prevent potential leakage.
