skeleton directory does not explain why an administrator may wish to
do this. This addition to the documentation provides context: a custom
skeleton directory is created to change the default files and folders
that ship with Nextcloud.

It also covers https://github.com/nextcloud/all-in-one/tree/main/community-containers/jellyfin by listening on `media.$NC_DOMAIN`, if installed.
### Notes
- This container is incompatible with the [npmplus](https://github.com/nextcloud/all-in-one/tree/main/community-containers/npmplus) community container. So make sure that you do not enable both at the same time!
- Make sure that no other service is using port 443 on your host as otherwise the containers will fail to start. You can check this with `sudo netstat -tulpn | grep 443` before installing AIO.
- If you want to use this with https://github.com/nextcloud/all-in-one/tree/main/community-containers/vaultwarden, make sure that you point `bw.your-nc-domain.com` to your server using a cname record so that caddy can get a certificate automatically for vaultwarden.
- If you want to use this with https://github.com/nextcloud/all-in-one/tree/main/community-containers/stalwart, make sure that you point `mail.your-nc-domain.com` to your server using a cname record so that caddy can get a certificate automatically for stalwart.
- After the container was started the first time, you should see a new `nextcloud-aio-caddy` folder and inside there an `allowed-countries.txt` file when you open the files app with the default `admin` user. In there you can adjust the allowed country codes for caddy by adding them to the first line, e.g. `IT FR` would allow access from italy and france. Private ip-ranges are always allowed. Additionally, in order to activate this config, you need to get an account at https://dev.maxmind.com/geoip/geolite2-free-geolocation-data and download the `GeoLite2-Country.mmdb` and upload it with this exact name into the `nextcloud-aio-caddy` folder. Afterwards restart all containers from the AIO interface and your new config should be active!
- You can add your own Caddy configurations in `/data/caddy-imports/` inside the Caddy container (`sudo docker exec -it nextcloud-aio-caddy bash`). These will be imported on container startup.
- See https://github.com/nextcloud/all-in-one/tree/main/community-containers#community-containers how to add it to the AIO stack
This container bundles DLNA server for your Nextcloud files to be accessible by the clients in your local network. Simply run the container and look for a new media server `nextcloud-aio` in your local network.
### Notes
- This container will work only if the Nextcloud installation is in your home network, it is not suitable for installations on remote servers.
- This is not working with Docker Desktop since it requires the `host` networking mode in docker, and it doesn't really share the host's network interfaces in this system
- If you have a firewall like ufw configured, you might need to open at least port 9999 TCP and 1900 UDP first in order to make it work.

This container bundles the external model of facerecognition and auto-configures it for you.
### Notes
- This container needs imaginary in order to analyze modern file format images. Make sure to enable imaginary in the AIO interface before adding this container.
- Facerecognition is by default disabled for all users, if you want to enable facerecognition for all users, you can run the following before adding this container:
- If facerecognition shall analyze shared files & folders (`sudo docker exec --user www-data -it nextcloud-aio-nextcloud php occ config:app:set facerecognition handle_shared_files --value true`), groupfolders (`sudo docker exec --user www-data -it nextcloud-aio-nextcloud php occ config:app:set facerecognition handle_group_files --value true`) and/or external storages (`sudo docker exec --user www-data -it nextcloud-aio-nextcloud php occ config:app:set facerecognition handle_external_files --value true`) in Nextcloud, you need to enable support for it manually first by running the mentioned commands before adding this container. See https://github.com/matiasdelellis/facerecognition/wiki/Settings#hidden-settings for further notes on each of these settings.

- This container is incompatible with the [Plex](https://github.com/nextcloud/all-in-one/tree/main/community-containers/plex) community container. So make sure that you do not enable both at the same time!
- This container does not work on Docker Desktop since it needs `network_mode: host` in order to work correctly.
- After adding and starting the container, you can directly visit http://ip.address.of.server:8096/ and access your new Jellyfin instance!
- In order to access your Jellyfin outside the local network, you have to set up your own reverse proxy. You can set up a reverse proxy following [these instructions](https://github.com/nextcloud/all-in-one/blob/main/reverse-proxy.md) and [Jellyfin's networking documentation](https://jellyfin.org/docs/general/networking/#running-jellyfin-behind-a-reverse-proxy), OR use the [Caddy](https://github.com/nextcloud/all-in-one/tree/main/community-containers/caddy) community container that will automatically configure `media.$NC_DOMAIN` to redirect to your Jellyfin.
- ⚠️ After the initial start, Jellyfin shows a configuration page to set up the root password, etc. **Be careful to initialize your Jellyfin before adding the DNS record.**
- The data of Jellyfin will be automatically included in AIO's backup solution!

Please refer [here](https://github.com/go-skynet/model-gallery/blob/main/index.yaml) where you can get further urls that you can put in there. Afterwards restart all containers from the AIO interface and the models should automatically get downloaded by the local-ai container and activated.

## How to add containers?
Simply submit a PR by creating a new folder in this directory: https://github.com/nextcloud/all-in-one/tree/main/community-containers with the name of your container. It must include a json file with the same name and with correct syntax and a readme.md with additional information. You might get inspired by caddy, fail2ban, local-ai, libretranslate, plex, pi-hole or vaultwarden (subfolders in this directory). For a full-blown example of the json file, see https://github.com/nextcloud/all-in-one/blob/main/php/containers.json. The json-schema that it validates against can be found here: https://github.com/nextcloud/all-in-one/blob/main/php/containers-schema.json.

Feel free to pick one up and add it to this folder by following the instructions above.
## How to remove containers from AIOs stack?
In some cases, you might want to remove some community containers from the AIO stack again. Here is how to do this.
First, do a backup from the AIO interface in order to save the current state. Do not start the containers again afterwards! Now simply recreate the mastercontainer and remove any container from the `--env AIO_COMMUNITY_CONTAINERS="container1 container2"` that you do not actually need. If you want to remove all, simply use `--env AIO_COMMUNITY_CONTAINERS=" "`.
After removing the containers, there might be some data left on your server that you might want to remove. You can get rid of the data by first running `sudo docker rm nextcloud-aio-container1`, (adjust `container1` accordingly) per community-container that you removed. Then run `sudo docker image prune -a` in order to remove all images that are not used anymore. As last step you can get rid of persistent data of these containers that is stored in volumes. You can check if there is some by running `sudo docker volume ls` and look for any volume that matches the ones that you removed. If so, you can remove them with `sudo docker volume rm nextcloud_aio_volume-id` (of course you need to adjust the `volume-id`).
This container bundles stalwart mail server and auto-configures it for you.
### Notes
- This is only intended to run on a VPS with static ip-address.
- Check with `sudo netstat -tulpn` that no other service is using port 25, 143, 465, 587, 993 nor 4190 yet as otherwise the container will fail to start.
- You need to configure a reverse proxy in order to run this container since stalwart needs a dedicated (sub)domain! For that, you might have a look at https://github.com/nextcloud/all-in-one/tree/main/community-containers/caddy.
- Currently, only `mail.$NC_DOMAIN` is supported as subdomain! So if Nextcloud is using `your-domain.com`, Stalwart will use `mail.your-domain.com`.
- The data of Stalwart will be automatically included in AIOs backup solution!
- After adding and starting the container, you need to run `sudo docker exec -it nextcloud-aio-stalwart configure.sh` and follow https://stalw.art/docs/install/docker/#choose-where-to-store-your-data (1. choose `Local disk using Maildir`, 2. choose `No, create a new directory for me` (or select LDAP if you have an LDAP server), 3. type in your `$NC_DOMAIN` as `domain name` and `mail.$NC_DOMAIN` as `server hostname`. 4. add `DKIM, SPF and DMARC` as advised to your DNS config, 5. Take note of the administrator credentials, 6. Now the config script should exit and automatically restart the container and enable your config.
- See https://stalw.art/docs/directory/types/memory/ how you can easily create new user accounts. (Alternatively see https://stalw.art/docs/directory/types/ldap if you have an LDAP server). You can edit the config file with `sudo docker exec -it nextcloud-aio-stalwart vi /opt/stalwart-mail/etc/config.toml`. Also, you might want to enable logging to stdout so that you can see the stalwart logs in your container logs via `sudo docker exec -it nextcloud-aio-stalwart vi /opt/stalwart-mail/etc/common/tracing.toml` (you need to restart the container afterwards with `sudo docker restart nextcloud-aio-stalwart` in order to apply the settings).
- Afterwards, you can visit the basic admin settings in `https://your-nc-domain.com/settings/admin` and add the your mail server for outgoing mails there.
- Additionally, you might want to install and configure [snappymail](https://apps.nextcloud.com/apps/snappymail) or [mail](https://apps.nextcloud.com/apps/mail) inside Nextcloud in order to use your mail accounts for sending and retrieving mails.

## Use the user_migration app
A new way since the Nextcloud update to 24 is to use the new [user_migration app](https://apps.nextcloud.com/apps/user_migration#app-gallery). It allows to export the most important data on one instance and import it on a different Nextcloud instance. For that, you need to install and enable the user_migration app on your old instance, trigger the export for the user, create the user on the new instance, log in with that user and import the archive that was created during the export. This then needs to be done for each user that you want to migrate.
If the restored data is older than any clients you want to continue to sync, for example if the server was down for a period of time during migration, you may want to take a look at [Synchronising with clients after migration](/migration.md#synchronising-with-clients-after-migration) below.
# Synchronising with clients after migration
#### From https://docs.nextcloud.com/server/latest/admin_manual/maintenance/restore.html#synchronising-with-clients-after-data-recovery
By default the Nextcloud server is considered the authoritative source for the data. If the data on the server and the client differs clients will default to fetching the data from the server.
If the recovered backup is outdated the state of the clients may be more up to date than the state of the server. In this case also make sure to run `sudo docker exec --user www-data -it nextcloud-aio-nextcloud php occ maintenance:data-fingerprint` command afterwards. It changes the logic of the synchronisation algorithm to try an recover as much data as possible. Files missing on the server are therefore recovered from the clients and in case of different content the users will be asked.
>[!Note]
>The usage of maintenance:data-fingerprint can cause conflict dialogues and difficulties deleting files on the client. Therefore it’s only recommended to prevent dataloss if the backup was outdated.
If you are running multiple application servers you will need to make sure the config files are synced between them so that the updated data-fingerprint is applied on all instances.
