DANGER

DO NOT USE THIS CODE YET. I found a serious security vulnerability during my vetting process of a dependency of this project. For now I have pulled my built images from Docker Hub. I will remove this warning and re-publish once the issue is resolved.

Docker image for Baïkal, with an eye for security:

• Uses a memory safe HTTP server (other images seem to be using Apache / nginx)
• Runs as non-root user
• I have vetted the security of most important dependencies

(Baïkal's own Docker image is in planning stages.)

How to run

$ docker run --rm -it \
	-v "/home/joonas/baikal-db:/data" \
	--user "$(id -u)" \
	--label traefik.frontend.rule=Host:baikal.example.com \
	joonas/baikal:SEE_TAG_FROM_DOCKERHUB

It is assumed that you're using TLS termination proxy in front of Baïkal like Traefik or Edgerouter (has traefik-compatible labels for HTTP ingress). Use of HTTPS is currently hardcoded into our headers.

Setting up

There's still interactive setup to do (I didn't bother skipping setup via specifying container vars because this is done only once)..

Notes:

• In Baïkal Settings set server time zone to UTC (inside container the time is UTC unless you explicitly defined something else via Docker command line).

• I suggest you set "Email invite sender address" as empty, because for now we don't support email

• I don't know what all "WebDAV authentication type" affects, but I set it to Basic and everything works for me. UPDATE: I tested with digest and it affects all clients so best set it to Basic!

• For "Baïkal Database Settings" the defaults work fine. (The container doesn't support MySQL. SQLite is fine.)

TODO

Calendar invitation / any emailing things are not set up! I'm pretty sure any of it doesn't work.

What works is:

• Baïkal's web UI
• syncing to Home Assistant
• syncing to Android app

State, backups

All state is in what you mount to /data inside the container. The state looks like this:

$ tree /home/joonas/baikal-db
/home/joonas/baikal-db
├── INSTALL_DISABLED
├── baikal.yaml
└── db
    └── db.sqlite

1 directory, 3 files

You should backup this file tree. If you use µbackup, you can specify BACKUP_COMMAND=tar -cC /data -f - .

Adding to OneCalendar in Android

Adding to Home Assistant

https://www.home-assistant.io/integrations/caldav/

NOTE: despite URL looking like https://baikal.my-server.net/cal.php/calendars/[email protected]/default it's not actually by email, rather username and it's better to not include /default as that refers to only one calendar, but actually use https://baikal.my-server.net/cal.php/calendars/[email protected] - your calendars will be discovered!

Includes Home Assistant patch
