Docker Environment for Development and Testing
⚠️ Important: The Docker environment is unable to connect to the PiSCSI board and is intended for development and testing purposes only. To setup PiSCSI on a Raspberry Pi refer to the setup instructions on the wiki instead.
Introduction
This documentation currently focuses on using Docker for developing and testing the web UI.
Additions, amendments and contributions for additional workflows are most welcome.
Getting Started
The easiest way to launch a new environment is to use Docker Compose.
cd docker
docker compose up
Containers will be built and started for the PiSCSI server and the web UI.
The web UI can be accessed at:
To stop the containers, press Ctrl + C, or run docker compose stop
from another terminal.
Environment Variables
The following environment variables are available when using Docker Compose:
| Environment Variable | Default |
|---|---|
OS_VERSION |
buster |
WEB_HTTP_PORT |
8080 |
WEB_HTTPS_PORT |
8443 |
WEB_LOG_LEVEL |
info |
BACKEND_HOST |
backend |
BACKEND_PORT |
6868 |
BACKEND_PASSWORD |
[None] |
BACKEND_LOG_LEVEL |
debug |
Examples:
Run Debian "bullseye":
OS_VERSION=bullseye docker compose up
Start the web UI with the log level set to debug:
WEB_LOG_LEVEL=debug docker compose up
Volumes
When using Docker Compose the following volumes will be mounted automatically:
| Local Path | Container Path |
|---|---|
| docker/volumes/images/ | /home/pi/images/ |
| docker/volumes/config/ | /home/pi/.config/piscsi/ |
How To
Rebuild Containers
You should rebuild the container images after checking out a different version of
PiSCSI or making changes which affect the environment at build time, e.g.
easyinstall.sh.
docker compose up --build
Open a Shell on a Running Container
Run the following command, replacing [CONTAINER] with backend or web.
docker compose exec [CONTAINER] bash
Setup Live Editing for the Web UI
Use a docker-compose.override.yml to mount the local python directory to
/home/pi/piscsi/python/ in the web container.
Any changes to *.py files on the host computer (i.e. in your IDE) will trigger the web UI process to be restarted in the container.
Example:
services:
web:
volumes:
- ../python:/home/pi/piscsi/python:delegated
Connect the Web UI to a Real PiSCSI
This can be useful for testing, but there are some caveats, e.g. the PiSCSI and the
web UI will be accessing separate images directories.
BACKEND_HOST=foo BACKEND_PASSWORD=bar docker compose up
