6 podman-logs - Display the logs of one or more containers
7
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. the run may not
20 have generated any logs at the time podman logs was executed).
21
24 --color
25 Output the containers with different colors in the log.
26 --follow, -f
29 Follow log output. Default is false.
30 Note: When following a container which is removed by podman container
33 rm or removed on exit (podman run --rm ...), there is a chance that the
34 log file is removed before podman logs reads the final content.
35 --latest, -l
38 Instead of providing the container name or ID, use the last created
39 container. Note: the last started container can be from other users of
40 Podman on the host machine. (This option is not available with the re‐
41 mote Podman client, including Mac and Windows (excluding WSL2) ma‐
42 chines)
43 --names, -n
46 Output the container names instead of the container IDs in the log.
47 --since=TIMESTAMP
50 Show logs since TIMESTAMP. The --since option can be Unix timestamps,
51 date formatted timestamps, or Go duration strings (e.g. 10m, 1h30m)
52 computed relative to the client machine's time. Supported formats for
53 date formatted time stamps include RFC3339Nano, RFC3339,
54 2006-01-02T15:04:05, 2006-01-02T15:04:05.999999999, 2006-01-02Z07:00,
55 and 2006-01-02.
56 --tail=LINES
59 Output the specified number of LINES at the end of the logs. LINES
60 must be an integer. Defaults to -1, which prints all lines
61 --timestamps, -t
64 Show timestamps in the log outputs. The default is false
65 --until=TIMESTAMP
68 Show logs until TIMESTAMP. The --until option can be Unix timestamps,
69 date formatted timestamps, or Go duration strings (e.g. 10m, 1h30m)
70 computed relative to the client machine's time. Supported formats for
71 date formatted time stamps include RFC3339Nano, RFC3339,
72 2006-01-02T15:04:05, 2006-01-02T15:04:05.999999999, 2006-01-02Z07:00,
73 and 2006-01-02.
