Installing Docker on pi raspberry pi

on a fresh raspbian lite install

  • install git sudo apt-get install git
  • install docker curl -fsSL https://get.docker.com -o get-docker.sh and then sudo sh get-docker.sh
  • allow current user to run containers sudo usermod -aG docker [user_name]

Run mpp-solar in docker (using mpp-solar docker image)

  • assuming docker is install (otherwise see next section)
  • pull image $ docker pull jblance/mppsolar 
Using default tag: latest

  • run a test command $ docker run --rm mpp mpp-solar -v 
Solar Device Command Utility, version: 0.15.59

Run development code in docker

FROM python:3.10-slim

COPY ./mpp-solar /mpp-solar/
RUN pip install -e /mpp-solar/

should have:

~ $ ls -l
-rw-r--r--  1 pi pi   84 May 18 15:16 Dockerfile
drwxr-xr-x 12 pi pi 4096 May 17 10:00 mpp-solar
  • build an image and tag it
    • $ docker build -t mp .
  • then commands can be run against it
    • $ docker run --rm mp powermon -C /mpp-solar/powermon/config/min.yaml
    • $ docker run --rm --device=/dev/hidraw0 mp mpp-solar -p /dev/hidraw0 -P pi30max -c QPI

build new docker image

  • prepare Dockerfile
FROM python:3.11-slim

RUN pip install mppsolar
  • build image $ docker build -t jblance/mppsolar:0.15.62 .
  • tag as latest $ docker tag jblance/mppsolar:0.15.62 jblance/mppsolar:latest
  • login $ docker login -u username
  • push to dockerhub $ docker push jblance/mppsolar:0.15.62
  • push latest tag $ docker push jblance/mppsolar

Run mpp-solar using Docker

created / tested by Rob Wolff

  1. Download the Dockerfile here or copy and paste below to the Docker server you want to run the mpp-solar container on:
FROM python:3.10.4-slim-bullseye
RUN apt update
RUN apt-get install -y pkg-config libsystemd-dev gcc
RUN pip install paho-mqtt systemd-python mppsolar
WORKDIR "/etc/mpp-solar"
CMD mpp-solar -C mpp-solar.conf --daemon

  1. In the same folder as the Dockerfile run docker build -t mpp-solar . to build the container.

  2. Create a config file called mpp-solar.conf where the rest of your docker config files are stored. Reference the mpp-solar config file documentation here or see mine as an example below:

[SETUP]
pause=1
mqtt_broker=MQTTHOST
mqtt_user=MQTTPASS
mqtt_pass=MQTTUSER

[LVX6048WP]
port=/dev/ttyUSB0
protocol=PI17
command=GS#PS
tag=mpp
outputs=hass_mqtt
  1. Run the container using Docker command:
$ docker run -d --name=mpp-solar \
    --restart unless-stopped \
    -v ${CONFIGDIR}/mpp-solar:/etc/mpp-solar \
    --device /dev/ttyUSB0:/dev/ttyUSB0 \
    --privileged \
    mpp-solar

Or run the container using Docker Compose:

version: '3'
services:
 mpp-solar:
   image: mpp-solar
   container_name: mpp-solar
   privileged: true
   restart: unless-stopped
   volumes:
     - ${CONFIGDIR}/mpp-solar:/etc/mpp-solar
   devices:
     - /dev/ttyUSB0:/dev/ttyUSB0

powermon with docker

running a simple mqtt container

docker run --rm --network=host -v ./docker/mosquitto/config:/mosquitto/config eclipse-mosquitto
