Container

Status: Experimental

type: container

Description: A container instance.

Attribute Type Description Examples Requirement Level
container.name string Container name used by container runtime. opentelemetry-autoconf Recommended
container.id string Container ID. Usually a UUID, as for example used to identify Docker containers. The UUID might be abbreviated. a3bf90e006b2 Recommended
container.runtime string The container runtime managing this container. docker; containerd; rkt Recommended
container.image.name string Name of the image the container was built on. gcr.io/opentelemetry/operator Recommended
container.image.tags string[] Container image tags. An example can be found in Docker Image Inspect. Should be only the <tag> section of the full name for example from registry.example.com/my-org/my-image:<tag>. [v1.27.1, 3.5.7-0] Recommended
container.image.id string Runtime specific image identifier. Usually a hash algorithm followed by a UUID. [1] sha256:19c92d0a00d1b66d897bceaa7319bee0dd38a10a851c60bcec9474aa3f01e50f Recommended
container.image.repo_digests string[] Repo digests of the container image as provided by the container runtime. [2] [example@sha256:afcc7f1ac1b49db317a7196c902e61c6c3c4607d63599ee1a82d702d249a0ccb, internal.registry.example.com:5000/example@sha256:b69959407d21e8a062e0416bf13405bb2b71ed7a84dde4158ebafacfa06f5578] Recommended
container.command string The command used to run the container (i.e. the command name). [3] otelcontribcol Opt-In
container.command_line string The full command run by the container as a single string representing the full command. [2] otelcontribcol --config config.yaml Opt-In
container.command_args string[] All the command arguments (including the command/executable itself) run by the container. [2] [otelcontribcol, --config, config.yaml] Opt-In
container.labels.<key> string Container labels, <key> being the label name, the value being the label value. container.labels.app=nginx Recommended

[1]: Docker defines a sha256 of the image id; container.image.id corresponds to the Image field from the Docker container inspect API endpoint. K8s defines a link to the container registry repository with digest "imageID": "registry.azurecr.io /namespace/service/dockerfile@sha256:bdeabd40c3a8a492eaf9e8e44d0ebbb84bac7ee25ac0cf8a7159d25f62555625". The ID is assinged by the container runtime and can vary in different environments. Consider using oci.manifest.digest if it is important to identify the same image in different environments/runtimes.

[2]: Docker and CRI report those under the RepoDigests field.

[3]: If using embedded credentials or sensitive data, it is recommended to remove them to prevent potential leakage.

Open Container Initiative (OCI)

The Open Container Initiative defines open industry standards around container formats and runtimes.

OCI Image Manifest

This section refers to the specification that defines an OCI Image manifest.

Status: Experimental

type: oci

Description: Attributes of an OCI image manifest.

Attribute Type Description Examples Requirement Level
oci.manifest.digest string The digest of the OCI image manifest. For container images specifically is the digest by which the container image is known. [1] sha256:e4ca62c0d62f3e886e684806dfe9d4e0cda60d54986898173c1083856cfda0f4 Recommended

[1]: Follows OCI Image Manifest Specification, and specifically the Digest property. An example can be found in Example Image Manifest.
