linuxserver/syslog-ng
syslog-ng allows you to flexibly collect, parse, classify, rewrite and correlate logs from across your infrastructure and store or route them to log analysis tools.

Supported Architectures

We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here.
Simply pulling lscr.io/linuxserver/syslog-ng:latest should retrieve the correct image for your arch, but you can also pull specific arch images via tags.
The architectures supported by this image are:
Architecture
Available
Tag
x86-64
amd64-<version tag>
arm64
arm64v8-<version tag>
armhf
arm32v7-<version tag>

Application Setup

Edit /config/syslog-ng.conf to configure your logging sources and destinations. Note: As the application does not run as root you cannot listen on ports < 1024.
More info at syslog-ng.

Usage

To help you get started creating a container from this image you can either use docker-compose or the docker cli.
---
version: "2.1"
services:
syslog-ng:
image: lscr.io/linuxserver/syslog-ng:latest
container_name: syslog-ng
environment:
- PUID=1000
- PGID=1000
- TZ=Europe/London
volumes:
- /path/to/config:/config
- /path/to/log:/var/log #optional
ports:
- 514:5514/udp
- 601:6601/tcp
- 6514:6514/tcp
restart: unless-stopped
docker run -d \
--name=syslog-ng \
-e PUID=1000 \
-e PGID=1000 \
-e TZ=Europe/London \
-p 514:5514/udp \
-p 601:6601/tcp \

-v /path/to/config:/config \
-v /path/to/log:/var/log `#optional` \
--restart unless-stopped \
lscr.io/linuxserver/syslog-ng:latest

Parameters

Docker images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate <external>:<internal> respectively. For example, -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080 outside the container.

Ports (-p)

Parameter
Function
5514/udp
Syslog UDP
6601/tcp
Syslog TCP
6514/tcp
Syslog TLS

Environment Variables (-e)

Env
Function
PUID=1000
for UserID - see below for explanation
PGID=1000
for GroupID - see below for explanation
TZ=Europe/London
Specify a timezone to use EG Europe/London.

Volume Mappings (-v)

Volume
Function
/config
Stores config and application files
/var/log
Stores logs collected by the syslog-ng service
Miscellaneous Options

Environment variables from files (Docker secrets)

You can set any environment variable from a file by using a special prepend FILE__.
As an example:
-e FILE__PASSWORD=/run/secrets/mysecretpassword
Will set the environment variable PASSWORD based on the contents of the /run/secrets/mysecretpassword file.

Umask for running applications

For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional -e UMASK=022 setting. Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up here before asking for support.

User / Group Identifiers

When using volumes (-v flags), permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user PUID and group PGID.
Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.
In this instance PUID=1000 and PGID=1000, to find yours use id user as below:
$ id username
uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)

Docker Mods

We publish various Docker Mods to enable additional functionality within the containers. The list of Mods available for this image (if any) as well as universal mods that can be applied to any one of our images can be accessed via the dynamic badges above.

Support Info

  • Shell access whilst the container is running:
    • docker exec -it syslog-ng /bin/bash
  • To monitor the logs of the container in realtime:
    • docker logs -f syslog-ng
  • Container version number
    • docker inspect -f '{{ index .Config.Labels "build_version" }}' syslog-ng
  • Image version number
    • docker inspect -f '{{ index .Config.Labels "build_version" }}' lscr.io/linuxserver/syslog-ng:latest
