Arcsecond CLI
The Command-line interface (CLI) for Arcsecond. It can be used as Python module too. The CLI makes it easy to login/register and access Arcsecond resources, public and private ones.
Running Arcsecond.local
The CLI owns the whole lifecycle of a self-hosted installation; there is no
docker command to type:
$ arcsecond setup --lan-host 192.168.1.42 # writes .env and docker-compose.yml
$ arcsecond token set # the access token Arcsecond gave you, once per machine (setup asks too)
$ arcsecond start # first run downloads the images
$ arcsecond status
$ arcsecond logs backend -f
$ arcsecond restart backend worker # after editing .env
$ arcsecond update # newer images, refreshed compose file
$ arcsecond stop
Every one of these finds the installation in the current folder, or in the
folder arcsecond setup last ran in, or where --dir points.
Which server the CLI talks to
The CLI points at one API server at a time — the cloud by default, or a server you registered, typically your own Arcsecond.local — and every command follows that pointer:
$ arcsecond api # list them, * marks the current one
$ arcsecond api use local # `setup` registered `local` for you
$ arcsecond login # on that server
Credentials are kept per server. For a script or a cron job, ARCSECOND_API=<name>
selects a server for that process alone, without moving the pointer.
Configuration
Credentials and settings live in ~/.config/arcsecond/, alongside the list of
registered cameras and the live-image proxy's runtime files.
Set ARCSECOND_CONFIG_DIR to put them somewhere else:
$ ARCSECOND_CONFIG_DIR=~/.config/arcsecond-observatory arcsecond login
Useful for keeping a personal account and an observatory's apart, and for
containers or CI jobs that should not touch a home directory. Child processes
the CLI starts — such as the background proxy from arcsecond proxy start —
inherit it.
Development
The project uses uv for environment and dependency management. After forking and cloning:
$ cd ~/arcsecond-cli
$ uv sync --extra webcam --group dev
$ uv run arcsecond --help
$ uv run pytest
uv sync creates .venv/ and installs the project with its webcam extra
and the dev dependency group (pytest, black, flake8, isort). Prefix
commands with uv run or activate the venv with source .venv/bin/activate.
The test suite writes nothing to your own configuration: an autouse fixture in
tests/conftest.py points ARCSECOND_CONFIG_DIR at a temporary directory for
the whole run. Several tests save real-looking credentials, so if you add one
that touches ArcsecondConfig, leave that fixture in place.
