使用Graylog2收集Docker日志

To find the current default logging driver for the Docker daemon, run docker info and search for Logging Driver. You can use the following command on Linux, macOS, or PowerShell on Windows:

-- https://docs.docker.com/engine/admin/logging/gelf/

-- https://docs.docker.com/engine/admin/logging/overview/

To use the

gelf

driver as the default logging driver, set the

log-driver

and

log-opt

keys to appropriate values in the

daemon.json

file, which is located in

/etc/docker/

on Linux hosts

To use

gelf

as the default logging driver for new containers, pass the

--log-driver

and

--log-opt

options to the Docker daemon:

dockerd
-–log-driver gelf –-log-opt gelf-address=udp://1.2.3.4:12201 \

To make the configuration permanent, you can configure it in

/etc/docker/daemon.json

:

{
"log-driver": "gelf",
"log-opts":  {
"gelf-address": "udp://1.2.3.4:12201"
"tag": "container"
}
}

You can set the logging driver for a specific container by setting the

--log-driver

flag when using

docker create

or

docker run

:

$ docker run \
-–log-driver gelf –-log-opt gelf-address=udp://1.2.3.4:12201 \
alpine echo hello world

You can try with this working example yaml:

example:
container_name: example
image: debian:wheezy
command: /bin/sh -c "while true; do date && echo "hello"; sleep 1; done"
ports:
- "1234:1234"
log_driver: "gelf"
log_opt:
gelf-address: "udp://graylog.example.com:12201"
gelf-tag: "first-logs"
