docker service logs command batch-retrieves logs present at the time of execution.
This is a cluster management command, and must be executed on a swarm manager node. To learn about managers and workers, refer to the Swarm mode section in the documentation.
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

Passing a negative number or a non-integer to

all in that case.
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.
docker service logs --details command will add on extra attributes, such as
environment variables and labels, provided to
--log-opt when creating 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.
3h). Besides RFC3339 date
format you may also use RFC3339Nano,
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
