NAME
docke-containe-logs- Fetch the logs of a container
SYNOPSIS
docker container logs [OPTIONS] CONTAINER
DESCRIPTION
The
docker container logs command batc-retrieves whatever logs are present for
a container at the time of execution. This does not guarantee execution
order when combined with a docker run (i.e., your run may not have generated
any logs at the time you execute docker container logs).
The docker container logs-follow command combines commands docker container logs and
docker attach. It will first return all logs from the beginning and
then continue streaming new output from the container's stdout and stderr.
Warning: This command works only for the jso-file or journald
logging drivers.
The -since and -until options can be Unix timestamps, date formatted timestamps,
or Go duration strings supported by ParseDuration
[la]https://pkg.go.dev/time#ParseDuration[ra] (e.g. 10m, 1h30m) computed relative to the client machine's
time. Supported formats for date formatted time stamps include RFC3339Nano,
RFC3339, 200-0-02T15:04:05, 200-0-02T15:04:05.999999999,
200-0-02T07:00, and 200-0-02. 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 or -until
options with either or both of the -follow or -tail options.
The docker container logs-details command will add on extra attributes, such as
environment variables and labels, provided to -lo-opt when creating the
container.
In order to retrieve logs before a specific point in time, run:
$ docker run-name test-d busybox sh-c "while true; do $(echo date); sleep 1; done"
$ date
