% 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 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 container name or ID, use the last created container. If you use methods other than Podman to run containers such as CRI-O, the last started container could be from either of those methods. 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 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 will fallback to executing ps(1) in the container 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 December 2017, Originally compiled by Brent Baude
