Migrate from old Docker deployment files

This guide helps you migrate from old Trendz Docker deployment files that used local folder volume bindings to the current named Docker volumes approach. Named volumes are more portable and easier to manage.

You need this guide if your docker-compose.yml uses local folder mounts like ~/.mytrendz-data and ~/.mytrendz-logs for Trendz and Postgres data:

volumes:
  - ~/.mytrendz-data:/data
  - ~/.mytrendz-logs:/var/log/trendz

version: '3.0'
services:
  mytrendz:
    restart: always
    image: "thingsboard/trendz:1.14.0"
    ports:
      - "8888:8888"
    environment:
      TB_API_URL: http://10.0.0.101:8080
      TRENDZ_LICENSE_INSTANCE_DATA_FILE: /data/license.data
      SPRING_DATASOURCE_URL: jdbc:postgresql://postgres:5432/trendz
      SPRING_DATASOURCE_USERNAME: postgres
      SPRING_DATASOURCE_PASSWORD: postgres
      SCRIPT_ENGINE_TIMEOUT: 30000
    volumes:
      - ~/.mytrendz-data:/data
      - ~/.mytrendz-logs:/var/log/trendz
  postgres:
    restart: always
    image: "postgres:15"
    ports:
      - "5432"
    environment:
      POSTGRES_DB: trendz
      POSTGRES_PASSWORD: postgres
    volumes:
      - ~/.mytrendz-data/db:/var/lib/postgresql/data

1. Create a named volume for Postgres and copy data into it:

   docker volume create --name trendz-postgres-data
   docker run --rm -v ~/.mytrendz-data/db:/source -v trendz-postgres-data:/destination alpine sh -c "cp -rp /source/* /destination/"

2. Create a named volume for Trendz and copy data into it:

   docker volume create --name trendz-data
   docker run --rm -v ~/.mytrendz-data/:/source -v trendz-data:/destination alpine sh -c "cp -rp /source/* /destination/"

3. Replace docker-compose.yml with the current manifest:

   nano docker-compose.yml

   Copy the current manifest from the Docker (Linux, macOS) installation guide (or the Windows guide if applicable). If you are staying on postgres:15, update the Postgres image tag accordingly.

4. Proceed with the upgrade:

   Once your data is in named volumes and docker-compose.yml matches the current structure, follow the Upgrade Instructions.
