内容説明Fetch the logs of a service or task
利用方法docker service logs [OPTIONS] SERVICE|TASK

Swarm このコマンドは Swarm オーケストレーターにおいて動作します。

内容説明

The docker service logs command batch-retrieves logs present at the time of execution.

メモ

これはクラスター管理コマンドであるため、Swarm のマネージャーノード上で実行する必要があります。 マネージャーノードとワーカーノードについては、本ドキュメントの Swarm モード を参照してください。

The docker service logs command can be used with either the name or ID of a service, or with the ID of a task. If a service is passed, it will display logs for all of the containers in that service. If a task is passed, it will only display logs from that particular task.

メモ

This command is only functional for services that are started with the json-file or journald logging driver.

For more information about selecting and configuring logging drivers, refer to Configure logging drivers.

The docker service logs --follow command will continue streaming the new output from the service'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.

The docker service logs --timestamps command will add an RFC3339Nano timestamp , 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.

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

The --since option shows only the service 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.
