Container Attributes

container.commandstringThe command used to run the container (i.e. the command name). [1]otelcontribcol
container.command_argsstring[]All the command arguments (including the command/executable itself) run by the container. [2][otelcontribcol, --config, config.yaml]
container.command_linestringThe full command run by the container as a single string representing the full command. [2]otelcontribcol --config config.yaml
container.idstringContainer ID. Usually a UUID, as for example used to identify Docker containers. The UUID might be abbreviated.a3bf90e006b2
container.image.idstringRuntime specific image identifier. Usually a hash algorithm followed by a UUID. [2]sha256:19c92d0a00d1b66d897bceaa7319bee0dd38a10a851c60bcec9474aa3f01e50f
container.image.namestringName of the image the container was built
container.image.repo_digestsstring[]Repo digests of the container image as provided by the container runtime. [3][example@sha256:afcc7f1ac1b49db317a7196c902e61c6c3c4607d63599ee1a82d702d249a0ccb,]
container.image.tagsstring[]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<tag>.[v1.27.1, 3.5.7-0]
container.labels.<key>stringContainer labels, <key> being the label name, the value being the label
container.namestringContainer name used by container runtime.opentelemetry-autoconf
container.runtimestringThe container runtime managing this container.docker; containerd; rkt

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

[2]: Docker defines a sha256 of the 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": " /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.

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