Docker repository: https://hub.docker.com/repository/docker/pieterhil/energy-management-system

How to use

The recommended method is to use Docker compose (See below). For instructions how to install docker desktop see https://docs.docker.com/desktop/ and docker engine (server) see https://docs.docker.com/engine/install/.

Docker compose

mkdir hems
cd hems
mkdir config

create config.json and a NLog.config in the 'config' subfolder. You can find examples of these in this repository folder docker/tests/config/

docker-compose.yml

version: '3.8'

services:
  hems:
    image: pieterhil/energy-management-system:latest
    container_name: hems
    user: 1001:123
    restart: unless-stopped
    ports:
      - "8080:8080"
    volumes:
      - ./config:/app/ems/userdata
    environment:
      - TZ=Europe/Amsterdam
      - EMS_PATHS_CONFIG=/app/ems/userdata/config.json
      - EMS_PATHS_NLOG=/app/ems/userdata/NLog.config

You can use the following two options to start the container:

docker-compose up -d

or

docker compose up -d

Updating the docker image

docker-compose pull pieterhil/energy-management-system:latest
docker-compose down
docker-compose up -d --remove-orphans
docker image prune

Docker

Get the latest image from the repository:

docker pull pieterhil/energy-management-system:latest

Remove any old containers from the system that where left over from a previous run.

docker container rm hems

docker run \
    -p 8080:8080 \
    --mount type=bind,source="$(pwd)"/config,destination=/app/ems/userdata \
    --user 1001:123
    -e TZ=Europe/Amsterdam \
    -e EMS_PATHS_CONFIG=/app/ems/userdata/config.json \
    -e EMS_PATHS_NLOG=/app/ems/userdata/NLog.config \
    --name=hems \
    pieterhil/energy-management-system:latest

Write access to local storage

The application does as user 'app' inside the docker container. For some systems it is mandatory that this user has write access to the volume so that logfiles and the databse can be saved. Some operating systems this is nod needed. For instance macOS is able to write in the mounted volume. It is recommended always to supply a user and group id that has write access to the local storage. You can do this in the docker-compose.yml file, or Some background information and other strategies for handling this issue can be found at the following blog post: Docker and the Host Filesystem Owner Matching Problem and can also be found at The Internet Archive WayBackMachine

Frontend

The frontend is accessible using the browser http://127.0.0.1:8080 if you are running the docker on you own local system.
