Installing ThingsBoard Trendz Analytics using Docker (Linux or Mac OS)

This guide will help you to install and start Trendz Analytics using Docker on Linux or Mac OS.

Prerequisites

Step 1. Obtain the license key

We assume you have already chosen subscription plan for Trendz and have license key. If not, please get your Free Trial license before you proceed. See How-to get pay-as-you-go subscription for more details.

Note: We will reference the license key you have obtained during this step as PUT_YOUR_LICENSE_SECRET_HERE later in this guide.

Step 2. Checkout Trendz Analytics image on Docker Hub

Open official Trendz Analytics Docker Hub page and proceed to checkout.

Populate basic information about yourself and click “Get Content”

Step 3. Running Trendz service

Docker Compose setup

Make sure your have logged in to docker hub using command line.

Create docker compose file for Trendz Analytics service:

1
sudo nano docker-compose.yml

Add the following line to the yml file. Don’t forget to replace “PUT_YOUR_LICENSE_SECRET_HERE” with your license secret obtained on the first step

version: '3.0'
services:
  mytrendz:
    restart: always
    image: "thingsboard/trendz:1.9.2-HF2"
    ports:
      - "8888:8888"
    environment:
      TB_API_URL: http://10.0.0.101:8080
      TRENDZ_LICENSE_SECRET: PUT_YOUR_LICENSE_SECRET_HERE
      TRENDZ_LICENSE_INSTANCE_DATA_FILE: /data/license.data
      SPRING_DATASOURCE_URL: jdbc:postgresql://postgres:5432/trendz
      SPRING_DATASOURCE_USERNAME: postgres
      SPRING_DATASOURCE_PASSWORD: postgres
    volumes:
      - ~/.mytrendz-data:/data
      - ~/.mytrendz-logs:/var/log/trendz
  postgres:
    restart: always
    image: "postgres:12"
    ports:
      - "5432"
    environment:
      POSTGRES_DB: trendz
      POSTGRES_PASSWORD: postgres
    volumes:
      - ~/.mytrendz-data/db:/var/lib/postgresql/data

Where:

  • TB_API_URL - url for connecting to ThingsBoard Rest API (for example http://10.5.0.11:8080). Note that ThingsBoard IP address should be resolvable from Trendz docker container
  • PUT_YOUR_LICENSE_SECRET_HERE - placeholder for your license secret obtained on the first step
  • 8888:8888 - connect local port 8888 to exposed internal HTTP port 8888
  • ~/.mytrendz-data:/data - mounts the volume ~/.mytrendz-data to Trendz data directory
  • ~/.mytrendz-data/db:/var/lib/postgresql/datad - mounts the volume ~/.mytrendz-data/db to Postgres data directory
  • ~/.mytrendz-logs:/var/log/thingsboard - mounts the volume ~/.mytrendz-logs to Trendz logs directory
  • mytrendz - friendly local name of this machine
  • --restart always - automatically start Trendz in case of system reboot and restart in case of failure.
  • thingsboard/trendz:1.9.2-HF2 - docker image

Run following commands, before starting docker container(s), to create folders for storing data and logs. These commands additionally will change owner of newly created folders to docker container user. To do this (to change user) chown command is used, and this command requires sudo permissions (command will request password for a sudo access):

1
2
mkdir -p ~/.mytb-edge-data && sudo chown -R 799:799 ~/.mytb-edge-data
mkdir -p ~/.mytb-edge-logs && sudo chown -R 799:799 ~/.mytb-edge-logs

NOTE: Replace directory ~/.mytb-edge-data and ~/.mytb-edge-logs with directories you’re planning to use in docker-compose.yml.

1
2
mkdir -p ~/.mytrendz-data && sudo chown -R 799:799 ~/.mytrendz-data
mkdir -p ~/.mytrendz-logs && sudo chown -R 799:799 ~/.mytrendz-logs

NOTE: replace directory ~/.mytrendz-data and ~/.mytrendz-logs with directories you’re planning to used in docker-compose.yml.

Running service

Set the terminal in the directory which contains the docker-compose.yml file and execute the following commands to up this docker compose directly:

1
2
docker compose up -d
docker compose logs -f mytrendz

ThingsBoard supports Docker Compose V2 (Docker Desktop or Compose plugin) starting from 3.4.2 release, because docker-compose as standalone setup is no longer supported by Docker.

We strongly recommend to update to Docker Compose V2 and use it.

If you still rely on using Docker Compose as docker-compose (with a hyphen), then please execute the following commands to start ThingsBoard:
docker-compose up -d
docker-compose logs -f mytrendz

After executing this command you can open http://{your-host-ip}:8888 in you browser (for ex. http://localhost:8888). You should see Trendz login page.

Authentication

For first authentication you need to use Tenant Administrator credentials from your ThingsBoard

Trendz uses ThingsBoard as an authentication service. During first sign in ThingsBoard service should be also available to validate credentials.

Detaching, stop and start commands

You can detach from session terminal using Ctrl-p Ctrl-q key sequence - the container will keep running in the background.

In case of any issues you can examine service logs for errors. For example to see Trendz container logs execute the following command:

1
docker compose logs -f mytrendz

To stop the container:

1
docker compose stop mytrendz

To start the container:

1
docker compose start mytrendz

Docker Compose as docker-compose (with a hyphen) is deprecated. It is recommended to use Docker Compose V2 instead.
If you still rely on docker compose as standalone here is the list of the above commands:
docker-compose logs -f mytrendz
docker-compose stop mytrendz
docker-compose start mytrendz

Upgrade Trendz Service

Below is example on how to upgrade from 1.8.0 to 1.9.2

  • Create a dump of your database:
1
docker compose exec postgres sh -c "pg_dump -U postgres trendz > /var/lib/postgresql/data/trendz_dump"

If you still rely on Docker Compose as docker-compose (with a hyphen) execute next command:
docker-compose exec postgres sh -c “pg_dump -U postgres trendz > /var/lib/postgresql/data/trendz_dump”

  • Set upgradeversion variable to your previous Trendz version.
1
docker compose exec mytrendz sh -c "echo '1.8.0' > /data/.upgradeversion" 

If you still rely on Docker Compose as docker-compose (with a hyphen) execute next command:
docker-compose exec mytrendz sh -c “echo ‘1.8.0’ > /data/.upgradeversion”

  • After this you need to update docker-compose.yml as in Step 3 but with 1.9.2 instead of 1.8.0-SNAPSHOT:

  • Restart Trendz container

1
2
docker compose stop mytrendz
docker compose up -d

If you still rely on Docker Compose as docker-compose (with a hyphen) here is the list of the above commands:
docker-compose stop mytrendz
docker-compose up -d

To upgrade Trendz to the latest version those steps should be done for each intermediate version.

Troubleshooting

DNS issues

NOTE If you observe errors related to DNS issues, for example

1
127.0.1.1:53: cannot unmarshal DNS message

You may configure your system to use Google public DNS servers. See corresponding Linux and Mac OS instructions.
