Vdirsyncer-DOCKERIZED
Vdirsyncer - sync calendars and addressbooks between servers and the local filesystem. DOCKERIZED!
New in 2.4.1: A Vdirsyncer autoupdate function has been added! :) If you set AUTOUPDATE to true then Vdirsyncer will update itself including all dependencies at container startup.
Also you are not able to set your own UID and GID anymore and the default value for both is 1000! I have done this, to drop the root and sudo privileges completely. You should use a docker volume and just mount the config file into the container, check out the docker-compose.yml, or when using bind mounts make sure that the folder is readable and writable!
I will no longer push the linux/arm/v7 docker image to the registry, because almost no one used this one.
Disclaimer: I am just the maintainer of this docker container, I did not write the software. Visit the Official Github Repository to thank the author(s)! :)
Vdirsyncer is a command-line tool for synchronizing calendars and addressbooks between a variety of servers and the local filesystem. The most popular usecase is to synchronize a server with a local folder and use a set of other programs to change the local events and contacts. Vdirsyncer can then synchronize those changes back to the server.
However, vdirsyncer is not limited to synchronizing between clients and servers. It can also be used to synchronize calendars and/or addressbooks between two servers directly.
It aims to be for calendars and contacts what OfflineIMAP is for emails.
Vdirsyncer also support many different servers:
- Baikal
- DavMail (Exchange, Outlook)
- FastMail
- iCloud
- Mailcow (SOGo)
- NextCloud
- Radicale
- Xandikos

Docker Hub - https://hub.docker.com/r/bleala/vdirsyncer
I built this image based on Alpine Linux and set up everything with python3, pip3 and pipx.
There will always be two different versions:
| Tag | Content |
|---|---|
| Latest | Contains the latest stable version |
| 2.x | Contains the Vdirsyncer, Python and Alpine versions mentioned at the bottom of the page |
There are also several platforms supported:
Platform:
- linux/amd64
- linux/arm64
Deprecated:
- linux/arm/v7
To start the container you can run docker run -d -e AUTOSYNC=true -v /path/to/local/folder:/vdirsyncer bleala/vdirsyncer:latest, but since docker compose is easier to maintain, I'll give you a valid docker compose example

You have to mount a local folder containing the config file. How to config
In the mounted folder you will also find a config.example which I copied inside the container for a quick reference.
The configuration file name is just config. Write everything in .ini style, like it is shown in the docs and in my config.example!
Attention: It is not recommended to use AUTODISCOVER=true by default, if you have never used Vdirsyncer before! If you set it to true, it will automatically accept everything Vdirsyncer asks, so don't ruin your calender/contacts structure! Use it only if you know what you are doing!
For first time use I recommend running docker exec -it vdirsyncer vdirsyncer discover. Maybe you have to say yes/no to a few questions, asked by Vdirsyncer. READ THE DOCS!
After you ran docker exec -it vdirsyncer vdirsyncer discover you can either run docker exec -it vdirsyncer /bin/bash -c "vdirsyncer metasync && vdirsyncer sync" or, if you have not set AUTOSYNC=true, set it to true and restart the container with docker compose restart. If you already set it to true, you can just wait until the cronjob runs or, as I said, run docker exec -it vdirsyncer /bin/bash -c "vdirsyncer metasync && vdirsyncer sync" to do it manually once.
Now it will sync everything for the first time.
When everything is okay, you can adjust the CRON_TIME value to your desired time. Check out Crontab.guru for help. Default synctime value is 15 minutes CRON_TIME=*/15 * * * *.
Everything that is done by Supercronic will get written to the log file and to the docker logs! Run docker logs -f vdirsyncer or docker compose logs -f to watch the logs.
Vdirsyncer does run with an user called vdirsyncer inside the container and not as root.
The UID and GID for this user are 1000, so be careful, if you use a bind mount instead of a docker volume.
Attention for Google users: As you can read in the Docs you have to specify a path for token_file = "PATH". In order to work properly, use an absolute path! So for the carddav storage set the token_file like token_file = "/vdirsyncer/google_carddav"and for the caldav storage like token_file = "/vdirsyncer/google_calendar".
The reason is, cron does not run the vdirsyncer command directly inside the /vdirsyncer folder, so if you use a relative path, vdirsyncer does not know where your google tokens are stored and the AUTOSYNC fails!
Even more attention for Google user: Because Google is Google you have to follow this instruction to get the Google sync working again: Google Instruction.
You can skip step 9, this has been done for you during the container build!
This has been tested and confirmed working for Vdirsyncer 0.18.0 from my side.
For Vdirsyncer 0.19.2 you have to follow this instruction to get the Google sync working again: Google Instruction
This has been tested and confirmed working for Vdirsyncer 0.19.0, Vdirsyncer 0.19.1 and Vdirsyncer 0.19.2 from my side.
You can set nine different environment variables if you want to:
| Variable | Info | Value |
|---|---|---|
TZ |
to set the corrent container and log time | default to Europe/Vienna, look here for possible values |
AUTODISCOVER |
is used to automatically run vdirsyncer discover |
default to false, can be true |
AUTOSYNC |
is used to automatically run vdirsyncer metasync && vdirsyncer sync |
default to false, can be true |
AUTOUPDATE |
is used to automatically update Vdirsyncer with all dependencies on container startup |
default to false, can be true |
CRON_TIME |
for Supercronic, you can adjust it to whatever time you want to |
default to */15 * * * *, look here for crontab generator |
POST_SYNC_SCRIPT_FILE |
Custom script file location, which can be used to automatically run a script after the cronjob vdirsyncer command(s) |
optional, default to nothing Example: /vdirsyncer/custom_script.sh You have to mount the file by yourself! Needs to be a bash script! |
LOG |
if you want to adjust the log file destination | optional, default to /vdirsyncer/vdirsyncer.log |
LOG_LEVEL |
if you want to adjust the log level | optional, default to nothing --> normal supercronic output Can be -quiet, -debug or no value --> leave variable empty |
VDIRSYNCER_CONFIG |
location, where Vdirsyncer reads the config from | default to /vdirsyncer/config DON'T CHANGE! |
New in 2.4.1: The UID and GID variables now have default values, which are not changable!
UID- default to1000.GID- default to1000.
Attention: As I mentioned, don't use AUTOSYNC=true and AUTODISCOVER=true as default. If you are running Vdirsyncer for the first time, just try everything manually, before you enable AUTOSYNC and AUTODISCOVER!
Attention 2: I recommend using this way for the pairs collections = [["mytest", "test", "3b4c9995-5c67-4021-9fa0-be4633623e1c"]] LINK
Attention 3: Nextcloud fucks up the whole thing pretty much, if you try to sync contacts from Nextcloud to Google or Apple. I don't know why, maybe it's a bug in vdirsyncer, so I decided to pair Nextcloud with a read_only storage. This way Nextcloud gets everything and does not fuck things up (Maybe also a problem with Owncloud, but I did not test it)
