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.  Please use the "h*"
       descriptors  if  you  want  to extract host-related information.  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 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.(This option is not available with the remote Podman
       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.

       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 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
