SYNOPSIS

10       podman logs [options] container [container...]

DESCRIPTION

17       The  podman  logs command batch-retrieves whatever logs are present for
18       one or more containers at the time of execution.  This does not guaran‐
19       tee  execution  order  when combined with podman run (i.e. your run may
20       not have generated any logs at the time you execute podman logs).
21
22

OPTIONS

24   --follow, -f
25       Follow log output.  Default is false.
26
27
28       Note: If you are following a container which  is  removed  podman  con‐
29       tainer  rm  or  removed  on  exit  podman run --rm ..., then there is a
30       chance the the log file will be removed before podman  logs  reads  the
31       final content.
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)
39
40
41   --names, -n
42       Output the container name in the log
43
44
45   --since=TIMESTAMP
46       Show logs since TIMESTAMP. The --since option can be  Unix  timestamps,
47       date  formatted  timestamps,  or  Go duration strings (e.g. 10m, 1h30m)
48       computed relative to the client machine's time. Supported  formats  for
49       date    formatted    time    stamps   include   RFC3339Nano,   RFC3339,
50       2006-01-02T15:04:05,  2006-01-02T15:04:05.999999999,  2006-01-02Z07:00,
51       and 2006-01-02.
52
53
54   --tail=LINES
55       Output  the  specified  number  of LINES at the end of the logs.  LINES
56       must be an integer.  Defaults to -1, which prints all lines
57
58
59   --timestamps, -t
60       Show timestamps in the log outputs.  The default is false
