podman-pod-top(1)

NAME

podman-pod-top - Display the running processes of containers in a pod

SYNOPSIS

podman pod top [options] pod [format-descriptors]

DESCRIPTION

Display the running processes of containers in a pod. The format-descriptors are ps (1) compatible AIX format descriptors but extended to print additional information, such as the seccomp mode or the effective capabilities of a given process. The descriptors can either be passed as separated arguments or as a single comma-separated argument. Note that you can also specify options and or flags of ps(1); in this case, Podman will fallback to executing ps with the specified arguments and flags in the container.

OPTIONS

--help, -h

Print usage statement

--latest, -l

Instead of providing the pod name or ID, use the last created pod.

The latest option is not supported on the remote client.

FORMAT DESCRIPTORS

The following descriptors are supported in addition to the AIX format descriptors mentioned in ps (1):

args, capbnd, capeff, capinh, capprm, comm, etime, group, hgroup, hpid, huser, label, nice, pcpu, pgid, pid, ppid, rgroup, ruser, seccomp, state, time, tty, user, vsz

capbnd

Set of bounding capabilities. See capabilities (7) for more information.

capeff

Set of effective capabilities. See capabilities (7) for more information.

capinh

Set of inheritable capabilities. See capabilities (7) for more information.

capprm

Set of permitted capabilities. See capabilities (7) for more information.

hgroup

The corresponding effective group of a container process on the host.

hpid

The corresponding host PID of a container process.

huser

The corresponding effective user of a container process on the host.

label

Current security attributes of the process.

seccomp

Seccomp mode of the process (i.e., disabled, strict or filter). See seccomp (2) for more information.

state

Process state codes (e.g, R for running, S for sleeping). See proc(5) for more information.

EXAMPLES

By default, podman-top prints data similar to ps -ef:

    $ podman pod top b031293491cc
    USER   PID   PPID   %CPU    ELAPSED             TTY   TIME   COMMAND
    root   1     0      0.000   2h5m38.737137571s   ?     0s     top
    root   8     0      0.000   2h5m15.737228361s   ?     0s     top

The output can be controlled by specifying format descriptors as arguments after the pod:

    $ podman pod top -l pid seccomp args %C
    PID   SECCOMP   COMMAND   %CPU
    1     filter    top       0.000
    1     filter    /bin/sh   0.000
