NAME

6       podman-top - Display the running processes of a container

SYNOPSIS

10       podman top [options] container [format-descriptors]

13       podman container top [options] container [format-descriptors]

DESCRIPTION

17       Display  the running processes of the container. The format-descriptors
18       are ps (1) compatible AIX format descriptors but extended to print  ad‐
19       ditional  information,  such as the seccomp mode or the effective capa‐
20       bilities of a given process. The descriptors can either  be  passed  as
21       separated  arguments or as a single comma-separated argument. Note that
22       you can also specify options and or flags of ps(1); in this case,  Pod‐
23       man  will  fallback  to  executing  ps with the specified arguments and
24       flags in the container.  Please use the "h*" descriptors if you want to
25       extract  host-related information.  For instance, podman top $name hpid
26       huser to display the PID and user of the processes in the host context.

OPTIONS

30   --help, -h
31       Print usage statement
32
33
34   --latest, -l
35       Instead of providing the container name or ID,  use  the  last  created
36       container.  If you use methods other than Podman to run containers such
37       as CRI-O, the last started container could  be  from  either  of  those
38       methods.(This option is not available with the remote Podman client)

77

79       hgroup
80
81
82       The corresponding effective group of a container process on the host.
83
84
85       hpid

121
122

EXAMPLES

124       By default, podman-top prints data similar to ps -ef:
125
126
127              $ podman top f5a62a71b07
128              USER   PID   PPID   %CPU    ELAPSED         TTY     TIME   COMMAND
129              root   1     0      0.000   20.386825206s   pts/0   0s     sh
130              root   7     1      0.000   16.386882887s   pts/0   0s     sleep
131              root   8     1      0.000   11.386886562s   pts/0   0s     vi
132
133
134
135       The output can be controlled by specifying format descriptors as  argu‐
136       ments after the container:
137
138
139              $ podman top -l pid seccomp args %C
140              PID   SECCOMP   COMMAND     %CPU
141              1     filter    sh          0.000
142              8     filter    vi /etc/    0.000
143
144
145
146       Podman  will fallback to executing ps(1) in the container if an unknown
147       descriptor is specified.
148
149
150              $ podman top -l -- aux
151              USER   PID   PPID   %CPU    ELAPSED             TTY   TIME   COMMAND
152              root   1     0      0.000   1h2m12.497061672s   ?     0s     sleep 100000
