erp-sandbox
Build a containerized ERPNext development environment from a single
config.toml. Install the tool once, run erp-sandbox init, edit one file, run
one command, and get a working bench with all source editable from the host.
Linux only, podman or Docker, no root required. The command is erp-sandbox,
or sandbox for short.
Start here
| Setting one up for the first time | docs/setup.md — ~30 min, 11 of it unattended |
| Working in one day to day | docs/using.md |
| Something is broken | docs/troubleshooting.md |
| Running environments on a shared VPS | docs/vps.md |
Working on erp-sandbox itself |
docs/contributing.md |
The short version, if you have done this before:
uv tool install erp-sandbox
erp-sandbox init acme-dev && cd ~/erp-sandboxes/acme-dev
$EDITOR config.toml .erp-sandbox/secrets.env # both inside ~/erp-sandboxes/acme-dev/
erp-sandbox build
Then open http://localhost:<ports.http> and log in as Administrator with
the ADMIN_PASSWORD you set.
Already installed? uv tool upgrade erp-sandbox — one tool serves every
environment on the machine (upgrading).
What you get
Four containers, one HTTP port:
| Service | What it does | Reachable from the host |
|---|---|---|
nginx |
the only entry point — / to web, /socket.io to realtime |
yes, ports.http |
bench |
honcho running the Procfile: web, socketio, scheduler, workers | no |
mariadb |
the site database | yes, ports.mariadb, on 127.0.0.1 |
redis |
cache, queue and socketio as logical DBs 0/1/2 | no |
Everything is bind-mounted from your project directory — bench/apps/ the
cloned source, bench/env/ the virtualenv, data/mariadb/ the database. So:
- Edit a
.pyon the host and the reloader picks it up. git statusworks in every app.- No
docker cp, no rebuild to change a line.
You can run several client environments side by side, each with its own ports.
What you need
Linux, Python 3.11+ on the host, podman (rootless) or Docker Engine with its
compose plugin, git, and ~20 GB free. The container images bring their own
Python, Node and wkhtmltopdf.
The full list, with a command to check each one, is step 1 of setup.md.
Two roots — understand this first
Almost every confusing moment with this tool comes from mixing these up.
| The package | A project | |
|---|---|---|
| What | erp-sandbox itself |
one client's environment |
| Holds | templates, compose file, bench Dockerfile |
config.toml, .erp-sandbox/, bench/, data/ |
| Installed | once per machine, shared | created by you, as many as you like |
| Upgrades | replaced wholesale | never touched |
Every verb except init acts on the environment containing your working
directory, found by walking up for .erp-sandbox/ — the same way bench finds
its bench. So erp-sandbox bench console works anywhere inside a project. Use
--project DIR to act on one from outside.
