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. your run may
20 not have generated any logs at the time you execute podman logs).
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: If you are following a container which is removed podman con‐
33 tainer rm or removed on exit podman run --rm ..., then there is a
34 chance that the log file will be removed before podman logs reads the
35 final content.
36 --latest, -l
39 Instead of providing the container name or ID, use the last created
40 container. If you use methods other than Podman to run containers such
41 as CRI-O, the last started container could be from either of those
42 methods. (This option is not available with the remote Podman client,
43 including Mac and Windows (excluding WSL2) machines)
44 --names, -n
47 Output the container name in the log
48 --since=TIMESTAMP
51 Show logs since TIMESTAMP. The --since option can be Unix timestamps,
52 date formatted timestamps, or Go duration strings (e.g. 10m, 1h30m)
53 computed relative to the client machine's time. Supported formats for
54 date formatted time stamps include RFC3339Nano, RFC3339,
55 2006-01-02T15:04:05, 2006-01-02T15:04:05.999999999, 2006-01-02Z07:00,
56 and 2006-01-02.
57 --tail=LINES
60 Output the specified number of LINES at the end of the logs. LINES
61 must be an integer. Defaults to -1, which prints all lines
62 --timestamps, -t
65 Show timestamps in the log outputs. The default is false
66 --until=TIMESTAMP
69 Show logs until TIMESTAMP. The --until option can be Unix timestamps,
70 date formatted timestamps, or Go duration strings (e.g. 10m, 1h30m)
71 computed relative to the client machine's time. Supported formats for
72 date formatted time stamps include RFC3339Nano, RFC3339,
73 2006-01-02T15:04:05, 2006-01-02T15:04:05.999999999, 2006-01-02Z07:00,
74 and 2006-01-02.
