Configuration

Set these in docker-compose.yml under environment:.

Variable	Default	Meaning
PORT	3000	Host port in docker-compose.yml (the container always listens on 3000)
INITIAL_ADMIN_USER / INITIAL_ADMIN_PASSWORD	–	Create the first admin on startup instead of via the web UI
TRUST_PROXY	false	Set to true behind a reverse proxy, so X-Forwarded-Proto/Host are trusted (secure cookies over HTTPS)
COOKIE_SECURE	auto	auto, true or false. auto marks cookies Secure only when the proxy reports HTTPS
SESSION_DAYS	90	How long a login lasts
SECRET_KEY	–	Encrypts stored credentials (calendar passwords, GitHub/GitLab tokens, links to other servers). If unset, a random key is created in data/secret.key; keep it with your backups
NAMEDAYS_URL	stat.ee list	Where to download the nameday calendar on first start; off to never download (admins can upload a list instead)
PUSH_CONTACT	mailto:streamline@example.org	Contact sent to push services with notifications (use your e-mail as mailto:you@…)
PUBLIC_URL	–	The address Streamline is reached at (e.g. https://todo.example.org); used for links in notifications and on printed sheets
BACKUP_HOURS / BACKUP_KEEP	24 / 7	Automatic backups into data/backups/ (0 hours = off) and how many to keep
LOG_LEVEL	info	e.g. debug, info,sqlx=warn
DATA_DIR	/data	Where the database lives (inside the container)

Everything else (people, groups, calendars, integrations, notifications) is set up in the app, under Settings.
