func Detect ¶

func Detect() string

Detect returns the ID of the container the process runs in, or "" when it is not running in a container (e.g. local development). Resolution order, most to least reliable:

1. MIABI_CONTAINER_ID — an explicit operator/compose override.
2. /proc/self/mountinfo — Docker bind-mounts /etc/hostname, /etc/hosts and /etc/resolv.conf from /var/lib/docker/containers/<id>/, giving the full ID.
3. /proc/self/cgroup — the cgroup path carries the ID on cgroup v1.
4. the hostname — Docker's default is the 12-char short ID.

func Match ¶

func Match(a, b string) bool

Match reports whether two container references identify the same container, tolerating the mix of short (12-char) and full (64-char) IDs Docker returns. It requires at least a 12-char overlap to avoid accidental matches, so an empty reference never matches.
