Options
-c, --container string Container name.
--file-path string Log-file path. File path has a priority over file-type. When file-path and file-type are unset, output stdout/stderr of target container.
--file-type string Log-file type. List them with list-logs cmd. When file-path and file-type are unset, output stdout/stderr of target container.
-f, --follow Specify if the logs should be streamed.
-h, --help help for logs

--prefix Prefix each log line with the log source (pod name and container name). Only take effect for stdout&stderr.
-p, --previous If true, print the logs for the previous instance of the container in a pod if it exists. Only take effect for stdout&stderr.
--since duration Only return logs newer than a relative duration like 5s, 2m, or 3h. Defaults to all logs. Only one of since-time / since may be used. Only take effect for stdout&stderr.

--match-server-version Require server version to match client version
-n, --namespace string If present, the namespace scope for this CLI request
--request-timeout string The length of time to wait before giving up on a single server request. Non-zero values should contain a corresponding time unit (e.g. 1s, 2m, 3h). A value of zero means don't timeout requests. (default "0")
