Overview ¶
containermetadata provides functionality for retrieving the kubernetes pod and container metadata or the docker container metadata for a particular PID. For kubernetes it uses the shared informer from the k8s client-go API (https://github.com/kubernetes/client-go/blob/master/tools/cache/shared_informer.go). Through the shared informer we are notified of changes in the state of pods in the Kubernetes cluster and can add the pod container metadata to the cache. As a backup to the kubernetes shared informer and to find the docker container metadata for each pid received (if it is not already in the container caches), it will retrieve the container id from the /proc/PID/cgroup and retrieve the metadata for the containerID.
