### Container Detector

Populates `container.id` for processes running on containers supporting : docker( cgroup v1 or v2 ) or with containerd

| Resource Attribute |  Description                                                                                                                             |
| ------------------ | ---------------------------------------------------------------------------------------------------------------------------------------- |
| `container.id`     | Value parsed from file `/proc/self/cgroup` (cgroup v1). If it doesn't exist, parse the value from file `/proc/self/mountinfo` (cgroup v2)|
