Build status
Logspout with GELF adapter and TCP+TLS support
A logspout docker image with TLS support.
This image contains Logspout which is compiled with [GELF adapter] and originally forked from https://github.com/karlvr/logspout-gelf so you can forward Docker logs in GELF to a Graylog server.
Docker hub images
Images are published in the following registry, ghcr.io/mictsi/logspout-gelf-tls/logspout-gelf-tls and https://hub.docker.com/r/kthse/logspout-gelf-tls.
Keep in mind that i am moving away from Docker Hub to Github Registry.
Usage
Modify the docker compose file to point to your graylogserver and run it with the docker-compose command.
Use gelf://my.log.server:12201 as protocol for gelf over udp and gelf+tls://my.log.server:12201 for gelf over TCP+TLS
CLI example for gelf over udp
docker run -d --name=logspout --restart=unless-stopped -h $(hostname -f) -v /var/run/docker.sock:/var/run/docker.sock ghcr.io/mictsi/logspout-gelf-tls/logspout-gelf-tls:latest gelf://my.log.server:12201
CLI example for gelf over TCP and with TLS encryption
docker run -d --name=logspout --restart=unless-stopped -h $(hostname -f) -v /var/run/docker.sock:/var/run/docker.sock ghcr.io/mictsi/logspout-gelf-tls/logspout-gelf-tls:latest gelf+tls://my.log.server:12201
Docker Compose example
You could use this image with the following docker-compose file for unencrypted gelf messages over udp:
version: '3'
services:
logspout:
image: ghcr.io/mictsi/logspout-gelf-tls/logspout-gelf-tls:latest
hostname: my.message.source
volumes:
- /var/run/docker.sock:/var/run/docker.sock
command: gelf://my.log.server:12201
restart: unless-stopped
or the following for sending gelf message over TLS+TCP:
version: '3'
services:
logspout:
image: ghcr.io/mictsi/logspout-gelf-tls/logspout-gelf-tls:latest
hostname: my.message.source
volumes:
- /var/run/docker.sock:/var/run/docker.sock
command: gelf+tls://my.log.server:12201
restart: unless-stopped
Disclaimer
This image is provided as-is and only with best effort. We try to update this image with the latest Logspout stable version.
