Raspberry Pi Docker Image for Open Source CPAP Analysis Reporter (OSCAR)

A Raspberry Pi Docker image for OSCAR to run inside Docker container and access it remotely using web browser. Includes script to pull data from an ezShare wifi card, so no need to pull the SD Card out of the CPAP machine!

Cron job configurable through enviroment variables to pull files from an ezShare wifi SD card adpater.

Once everything is set up point your browser to http://192.168.xx.xx:8080

Repository name in Docker Hub: desertblade/oscar-pi
Published via automated build mechanism

Pre-reqs

Raspberry Pi with OS Lite installed. Tested with Raspberry Pi 4GB.

ezShare wifi SD adapter and an SD card, be sure to chose the combo for around $24! Configured and installed in your CPAP machine

USB wifi adapter. I find it easier to use dual wifi and you can get a decent adapter for under $10. Will add some recomendations later.

Configure Dual Wifi

Assuming you are all set with you primary wifi network here is how I configured my wifi.

Move existing configuration over:

$ mv /etc/wpa_supplicant/wpa_supplicant.conf /etc/wpa_supplicant/wpa_supplicant-wlan0.conf 

Create wlan1 wifi configuration (I copy over wlan0 as a starting point)

$ cp /etc/wpa_supplicant/wpa_supplicant-wlan0.conf /etc/wpa_supplicant/wpa_supplicant-wlan1.conf 

Edit the file:

$ nano /etc/wpa_supplicant/wpa_supplicant-wlan1.conf 

Change Network info to you ezshare:

network={
    ssid="ezShareSSD"
    psk="my_password_in_plaintext"
}

Reboot Pi (sudo reboot). When its back up you should be able to SSH in and ping 192.168.4.1 which is the ezShare card.

Install Docker

Follow instructions to install Docker from: https://docs.docker.com/engine/install/raspberry-pi-os/#install-using-the-repository

Docker Run

To simply do a quick and dirty run of the Oscar container:

sudo docker run \
    -d --rm \
    --name oscar \
    -v=/home/pi/oscar-data:/data:rw \
    -v=/home/pi/SDCARD:/SDCARD:rw \
    --publish=8080:8080 \
     desertblade/oscar-pi
  

To stop the container simply run:

$ sudo docker stop oscar

To remove the container simply run:

$ sudo docker rm oscar

Docker Compose

If you don't want to type out these long Docker commands, you could optionally use docker-compose to set up your image. Just download the repo and run it like so:

Or you could Donwload the docker-compose only:

$ wget https://raw.githubusercontent.com/desertblade/docker-oscar-pi/main/docker-compose.yml

version: '3.3'
services:
  oscar:
    image: desertblade/oscar-pi
    container_name: oscar
    restart: unless-stopped
    ports:
      - 8080:8080
    volumes:
      - /home/pi/oscar-data:/data:rw
      - /home/pi/SDCARD:/SDCARD:rw
    environment:
      TZ: "America/Los_Angeles"
      # Optional, if removed no Cronjob will be created
      CRON_HOUR: 7
      CRON_MIN: 30

To start the container run:

$ sudo docker compose up -d

To pull latest image and upgrade the docker instance:

$ sudo docker compose pull && sudo docker compose up -d
