containersmap

type ContainersMap ¶

type ContainersMap struct {
	// contains filtered or unexported fields
}

ContainersMap creates a global map /sys/fs/bpf/gadget/containers exposing container details for each mount namespace.

This makes it possible for gadgets to access that information and display it directly from the BPF code. Example of such code:

struct container *container_entry;
container_entry = bpf_map_lookup_elem(&containers, &mntns_id);

External tools such as tracee or bpftrace could also benefit from this just by using this "containers" map (other interaction with Inspektor Gadget is not necessary for this).
