# logs
|
||
|
||
Usage: docker logs [OPTIONS] CONTAINER
|
||
|
||
Fetch the logs of a container
|
||
|
||
-f, --follow=false Follow log output
|
||
--since="" Show logs since timestamp
|
||
-t, --timestamps=false Show timestamps
|
||
--tail="all" Number of lines to show from the end of the logs
|
||
|
||
NOTE: this command is available only for containers with `json-file` logging
|
||
driver.
|
||
|
||
The `docker logs` command batch-retrieves logs present at the time of execution.
|
||
|
||
The `docker logs --follow` command will continue streaming the new output from
|
||
the container's `STDOUT` and `STDERR`.
|
||
|
||
Passing a negative number or a non-integer to `--tail` is invalid and the
|
||
value is set to `all` in that case. This behavior may change in the future.
|
||
|
||
The `docker logs --timestamp` commands will add an RFC3339Nano
|
||
timestamp, for example `2014-09-16T06:17:46.000000000Z`, to each
|
||
log entry. To ensure that the timestamps for are aligned the
|
||
nano-second part of the timestamp will be padded with zero when necessary.
|
||
|
||
The `--since` option shows only the container logs generated after
|
||
a given date. You can specify the date as an RFC 3339 date, a UNIX
|
||
timestamp, or a Go duration string (e.g. `1m30s`, `3h`). Docker computes
|
||
the date relative to the client machine’s time. You can combine
|
||
the `--since` option with either or both of the `--follow` or `--tail` options.
