Docker compose is the recommended way to run this image. Copy the content of
folder examples/compose in /var/librenms/
on your host
for example. Edit the compose and env files with your preferences and run the
following commands:
$ docker compose up -d
$ docker compose logs -f
You can also use the following minimal command:
$ docker run -d -p 8000:8000 --name librenms \
-v $(pwd)/data:/data \
-e "DB_HOST=db" \
librenms/librenms:latest
Warning
db
must be a running MySQL instance.
When you first access the webui, you will be prompted to create an admin user.
Note
If you lose access, you can create another one using the
lnms
command.
To upgrade to the latest version of LibreNMS, pull the newer image and launch the container. LibreNMS will upgrade automatically:
$ docker compose down
$ docker compose pull
$ docker compose up -d
You can set the initial configuration of LibreNMS by placing *.yaml
files inside /data/config
folder. Let's say you want to edit the WebUI config.
Create a file called for example /data/config/webui.yaml
with this content :
page_refresh: 300
webui.default_dashboard_id: 0
This configuration will be seeded into the LibreNMS database when it is first deployed and will override the default values.
You can edit the running configuration via the LibreNMS web UI or lnms config:set
docker compose exec librenms lnms config:set page_refresh 300
Set REAPPLY_YAML_CONFIG=1
to overwrite any settings that are set during initial config
or via user config back to their initial values every time the container is deployed.
Using this config method, configuration changes will be reflected live on the containers, BUT you will be unable to edit the configured settings from within the LibreNMS web UI or lnms config:set.
The same example using PHP /data/config/webui.php
<?php
$config['page_refresh'] = "300";
$config['webui']['default_dashboard_id'] = 0;
If you want to use the lnms
command to perform common server operations like
manage users, database migration, and more, type:
$ docker compose exec librenms lnms
If you want to validate your installation from the CLI, type the following command:
$ docker compose exec --user librenms librenms php validate.php

If you want to enable the new Dispatcher service, you have to run a "sidecar" container (see dispatcher service in compose.yml example) or run a simple container like this:
$ docker run -d --name librenms_dispatcher \
--env-file $(pwd)/librenms.env \
-e SIDECAR_DISPATCHER=1 \
-e DISPATCHER_NODE_ID=dispatcher1 \
-v librenms:/data \
librenms/librenms:latest
Warning
librenms
must be a valid volume already attached to a LibreNMS container.
If you want to enable syslog-ng, you have to run a "sidecar" container (see syslog-ng service in compose.yml example) or run a simple container like this:
$ docker run -d --name librenms_syslog \
--env-file $(pwd)/librenms.env \
-e SIDECAR_SYSLOGNG=1 \
-p 514 -p 514/udp \
-v librenms:/data \
librenms/librenms:latest
Warning
librenms
must be a valid volume already attached to a LibreNMS container.
You have to create a configuration file to enable syslog in LibreNMS too. Create
a file called for example /data/config/syslog.yaml
with this content :
enable_syslog: true
If you want to enable snmptrapd, you have to run a "sidecar" container (see snmptrapd service in compose.yml example) or run a simple container like this:
$ docker run -d --name librenms_snmptrapd \
--env-file $(pwd)/librenms.env \
-e SIDECAR_SNMPTRAPD=1 \
-p 162 -p 162/udp \
-v librenms:/data \
librenms/librenms:latest
Warning
librenms
must be a valid volume already attached to a LibreNMS container.
You can add plugins for LibreNMS
in /data/plugins/
. If you add a plugin that already exists in LibreNMS, it
will be removed and yours will be used (except for Weathermap).
Warning
Container has to be restarted to propagate changes.
You can add a custom Monitoring plugin in /data/monitoring-plugins/
.
Some plugins can be found in the Monitoring Plugins repo, or in the unofficial fork for Nagios.
Warning
Container has to be restarted to propagate changes.
You can add Laravel alert templates
in /data/alert-templates/
.
Warning
Container has to be restarted to propagate changes.
