Struct Container 

pub struct Container {
    pub runtime: &'static str,
    pub id: String,
}

What a cgroup path says about the process’s container membership.

htop decides this from cgroup membership rather than heuristics, and so do we. The distinction that matters for a column is not “is it in a container” but which one: container_from_cgroup returning the bare marker ("docker") made every containerised process on the machine render the same word, which is a boolean dressed up as data.

Fields

runtime: &'static str

The runtime that owns it: docker, kubepods, lxc, …

id: String

The container’s identifier, as the cgroup path spells it.

For Docker and Podman this is the 64-hex id (or a prefix of it); for Kubernetes it is the pod uid. Empty when the path names a runtime but no identifiable container — a kubepods.slice with no pod below it, say.

Implementations

impl Container

pub fn short_id(&self) -> &str

The id shortened to the first 12 characters, which is what Docker prints and enough to tell containers apart on screen.

Shortening here rather than at render time keeps the column and the inspector agreeing; it also means the sort key and the displayed text are the same string.
