examples: |-
    ### Stream log output  (-f, --follow) {#follow}

    The `docker logs --follow` command will continue streaming the new output from
    the container's `STDOUT` and `STDERR`.

    ### Retrieve the last logs (-n, --tail) {#tail}

    Passing a negative number or a non-integer to `--tail` is invalid and the
    value is set to `all` in that case.


    ### Retrieve logs with timestamps (-t, --timestamps) {#timestamps}

    The `docker logs --timestamps` command will add an [RFC3339Nano timestamp](https://pkg.go.dev/time#RFC3339Nano)
    , for example `2014-09-16T06:17:46.000000000Z`, to each
    log entry. To ensure that the timestamps are aligned the
    nano-second part of the timestamp will be padded with zero when necessary.

    ### Retrieve logs with additional attributes (--details) {#details}

    The `docker logs --details` command will add on extra attributes, such as
    environment variables and labels, provided to `--log-opt` when creating the
    container.

    ### Retrieve logs generated since a specific point in time (--since) {#since}

    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`). Besides RFC3339 date
    format you may also use RFC3339Nano, `2006-01-02T15:04:05`,
    `2006-01-02T15:04:05.999999999`, `2006-01-02T07:00`, and `2006-01-02`. The local
    timezone on the client will be used if you do not provide either a `Z` or a
    `+-00:00` timezone offset at the end of the timestamp. When providing Unix
    timestamps enter seconds[.nanoseconds], where seconds is the number of seconds
    that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap
    seconds (aka Unix epoch or Unix time), and the optional .nanoseconds field is a
    fraction of a second no more than nine digits long. You can combine the
    `--since` option with either or both of the `--follow` or `--tail` options.


    ### Retrieve logs until a specific point in time (--until) {#until}

    In order to retrieve logs before a specific point in time, run:

    ```console
    $ docker run --name test -d busybox sh -c "while true; do $(echo date); sleep 1; done"
    $ date
    Tue 14 Nov 2017 16:40:00 CET
    $ docker logs -f --until=2s test
    Tue 14 Nov 2017 16:40:00 CET
    Tue 14 Nov 2017 16:40:01 CET
    Tue 14 Nov 2017 16:40:02 CET
    ```
