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.
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> |
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.The application pid, control file, etc. are all kept in /config so when using tools such as
syslog-ng-ctl you need to specify the path e.g. syslog-ng-ctl reload -c /config/syslog-ng.ctlTo help you get started creating a container from this image you can either use docker-compose or the docker cli.

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.Parameter | Function |
|---|---|
5514/udp | Syslog UDP |
6601/tcp | Syslog TCP |
6514/tcp | Syslog TLS |
Env | Function |
|---|---|
PUID=1000 | for UserID - see below for explanation |
PGID=1000 | for GroupID - see below for explanation |
TZ=Etc/UTC |
Volume | Function |
|---|---|
/config | Stores config and application files |
/var/log | Stores logs collected by the syslog-ng service |
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.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.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)
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.
- 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
