podman-logs(1) General Commands Manual podman-logs(1) NAME podman-logs - Display the logs of one or more containers SYNOPSIS podman logs [options] container [container...] podman container logs [options] container [container...] DESCRIPTION The podman logs command batch-retrieves whatever logs are present for one or more containers at the time of execution. This does not guaran- tee execution order when combined with podman run (i.e. the run may not have generated any logs at the time podman logs was executed). OPTIONS --color Output the containers with different colors in the log. --follow, -f Follow log output. Default is false. Note: When following a container which is removed by podman container rm or removed on exit (podman run --rm ...), there is a chance that the log file is removed before podman logs reads the final content. --latest, -l Instead of providing the container name or ID, use the last created container. Note: the last started container can be from other users of Podman on the host machine. (This option is not available with the re- mote Podman client, including Mac and Windows (excluding WSL2) ma- chines) --names, -n Output the container names instead of the container IDs in the log. --since=TIMESTAMP Show logs since TIMESTAMP. The --since option can be Unix timestamps, date formatted timestamps, or Go duration strings (e.g. 10m, 1h30m) computed relative to the client machine's time. Supported formats for date formatted time stamps include RFC3339Nano, RFC3339, 2006-01-02T15:04:05, 2006-01-02T15:04:05.999999999, 2006-01-02Z07:00, and 2006-01-02. --tail=LINES Output the specified number of LINES at the end of the logs. LINES must be an integer. Defaults to -1, which prints all lines --timestamps, -t Show timestamps in the log outputs. The default is false --until=TIMESTAMP Show logs until TIMESTAMP. The --until option can be Unix timestamps, date formatted timestamps, or Go duration strings (e.g. 10m, 1h30m) computed relative to the client machine's time. Supported formats for date formatted time stamps include RFC3339Nano, RFC3339, 2006-01-02T15:04:05, 2006-01-02T15:04:05.999999999, 2006-01-02Z07:00, and 2006-01-02.
