6 podman-logs - Display the logs of one or more containers

10 podman logs [options] container [container...]
11 podman container logs [options] container [container...]
14
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
24 --follow, -f
25 Follow log output. Default is false.
26 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 --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.
39 The latest option is not supported on the remote client.
42 --names, -n
45 Output the container name in the log
46 --since=TIMESTAMP
49 Show logs since TIMESTAMP. The --since option can be Unix timestamps,
50 date formatted timestamps, or Go duration strings (e.g. 10m, 1h30m)
51 computed relative to the client machine's time. Supported formats for
52 date formatted time stamps include RFC3339Nano, RFC3339,
53 2006-01-02T15:04:05, 2006-01-02T15:04:05.999999999, 2006-01-02Z07:00,
54 and 2006-01-02.
55 --tail=LINES
58 Output the specified number of LINES at the end of the logs. LINES
59 must be an integer. Defaults to -1, which prints all lines
60 --timestamps, -t
63 Show timestamps in the log outputs. The default is false
64
