Docker Compose

This page assumes that you have decided to start Unpoller using docker-compose. The setup detailed below will install containers for Unpoller, Grafana and InfluxDB

First

Make sure you have set up a user on your controller for Unpoller.

---

Installation

Unpoller's Docker container can be configured in two ways:

1. Using environment variables.
2. Using a configuration file.

Which to use is a matter of personal choice. The environmental path has the advantage that all settings are in one place (albeit a hidden file, and one where all information is available to all containers). The config file method has the advantage that Unpoller specific settings can be saved in the same shared Docker folder as the rest of the app's data.

There is a detailed description of the configuration parameters on the Application Configuration page.

Both of the alternatives described here will pull containers not just for Unpoller, but also for InfluxDB and Grafana. If you wish to use existing instances then amend the files as necessary.

Using Environment Variables

The easiest way to pass environment variables via docker-compose is to have a file called .env in the same folder as the docker-compose yaml file

Hidden Files

Files beginning with a period . are generally hidden. You may need to use ls -a to find the .env file.

• Copy the example environment file
• Edit it as necessary (in particular ensure that UNIFI_USER and UNIFI_PASS are set)
• Save it as .env in the same folder as your docker-compose.yml (if you have one; if not see below)

Download the example docker-compose.yml and add it to your existing one (if you have one; if not just make sure it is saved in the same folder as the .env file)

Prometheus Example

This example is advanced, for demonstration only, and not recommend for newbies.

Advanced Prometheus Example

---

The following example illustrates launching Grafana, Prometheus and Unpoller with docker compose. This does not utilize a .env file nor a configuration file and instead puts all the env variables directly into the docker-compose file. This still requires a Prometheus configuration to scrape Poller.

note

This is a community provided example.

      UP_UNIFI_CONTROLLER_0_USER=unpoller

  prometheus-data:

Using Configuration File

Alternatively, if you choose to use a configuration file:

• Copy the example config file
• Edit it as necessary (in particular ensure that the [unifi]/user and pass variables are set)
• In the [influxdb] section change url = "http://127.0.0.1:8086" to become url = "http://THE_IP_OF_YOUR_DOCKER_HOST:8086"
• Save it as unpoller.conf in the local location you use for Docker storage in a folder called unpoller

info

When configuring make sure that you do not include :8443 on the url of the controller if you are using unifios. Those are: UDM Pro, UDM, UXG, or CloudKey with recent firmware.

Add the following to your docker-compose.yml after replacing YOURLOCALPATH to a local location for Docker storage.

InfluxDB Example

Create this environment file docker-compose.env and reference this with -e /your/path/docker-compose.env:

#influxdb
INFLUXDB_HTTP_AUTH_ENABLED=true
INFLUXDB_ADMIN_USER=unpoller
INFLUXDB_ADMIN_PASSWORD=CHANGEME
INFLUXDB_DB=unpoller
INFLUXDB_ORG=unpoller
INFLUXDB_BUCKET=unpoller
INFLUXDB_ADMIN_TOKEN=unpollersecret

#grafana
GRAFANA_USERNAME=admin
GRAFANA_PASSWORD=grafanaadmin

#unifi-poller
POLLER_TAG=latest
POLLER_DEBUG=false
POLLER_SAVE_DPI=false
UNIFI_USER=unpoller
UNIFI_PASS=set_this_on_your_controller
UNIFI_URL=https://127.0.0.1:8443

The docker-compose.yml file:

Details of tags available are described in Docker - FAQ.

Starting

Whichever configuration method you chose, this is how you start the contianers:

docker-compose up -e docker-compose.env

If everything is working, after a few minutes you should see like likes this:

[INFO] UniFi Metrics Recorded. Sites: 1, Clients: 67, UAP: 6, USG/UDM: 1, USW: 5, IDS Events: 0, Points: 1837, Fields: 11307, Errs: 0, Elapsed: 599ms

If you don't see these lines then look for errors and double-check your work.

tip

You can see the logs for a container with docker logs container-id. Get the container id with docker ps.

Stop the containers and restart them in daemon mode, like this:

docker-compose up -e docker-compose.env -d

Next Steps

1. Creating an InfluxDB database and retention policy is explained on the InfluxDB page.
2. Finish Setting-up Grafana.
