podman-top(1) General Commands Manual podman-top(1) NAME podman-top - Display the running processes of a container SYNOPSIS podman top [options] container [format-descriptors] podman container top [options] container [format-descriptors] DESCRIPTION Display the running processes of the container. 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 options and or flags of ps(1) can also be specified; in this case, Podman falls back to executing ps(1) from the host with the specified arguments and flags in the container namespace. If the container has the CAP_SYS_PTRACE capability then we will execute ps(1) in the container so it must be installed there. To extract host-related information, use the "h*" descriptors. For instance, podman top $name hpid huser to display the PID and user of the processes in the host context. OPTIONS --help, -h Print usage statement --latest, -l Instead of providing the container name or ID, use the last created con- tainer. Note: the last started container can be from other users of Podman on the host machine. (This option is not available with the remote Podman client, including Mac and Windows (excluding WSL2) machines) FORMAT DESCRIPTORS The following descriptors are supported in addition to the AIX format de- scriptors mentioned in ps (1): args, capbnd, capeff, capinh, capprm, comm, etime, group, groups, hgroup, hgroups, 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. group The effective group of the process. groups The supplementary groups of the process. hgroup The corresponding effective group of a container process on the host. hgroups The corresponding supplementary groups 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. stime Process start time (e.g, "2019-12-09 10:50:36 +0100 CET). EXAMPLES By default, podman-top prints data similar to ps -ef. $ podman top f5a62a71b07 USER PID PPID %CPU ELAPSED TTY TIME COMMAND root 1 0 0.000 20.386825206s pts/0 0s sh root 7 1 0.000 16.386882887s pts/0 0s sleep root 8 1 0.000 11.386886562s pts/0 0s vi The output can be controlled by specifying format descriptors as arguments after the container. $ podman top -l pid seccomp args %C PID SECCOMP COMMAND %CPU 1 filter sh 0.000 8 filter vi /etc/ 0.000 Podman falls back to executing ps(1) from the host in the container name- space if an unknown descriptor is specified. $ podman top -l -- aux USER PID PPID %CPU ELAPSED TTY TIME COMMAND root 1 0 0.000 1h2m12.497061672s ? 0s sleep 100000 SEE ALSO podman(1), ps(1), seccomp(2), proc(5), capabilities(7) HISTORY July 2018, Introduce format descriptors by Valentin Rothberg vroth- berg@suse.com <mailto:vrothberg@suse.com> December 2017, Originally compiled by Brent Baude bbaude@redhat.com <mailto:bbaude@redhat.com> podman-top(1)
