 1. Expose the privileged ports by following https://docs.docker.com/engine/security/rootless/#exposing-privileged-ports. (`sudo setcap cap_net_bind_service=ep $(which rootlesskit); systemctl --user restart docker`)

 1. Now everything should work like without docker rootless. You can consider using docker-compose for this or running it behind a reverse proxy. Basically the only thing that needs to be adjusted always in the startup command or docker-compose file (after installing docker rootles) are things that are mentioned in point 3.
 
 **Please note:** All files outside the containers get created, written to and accessed as the user that is running the docker daemon or a subuid of it. So for the built-in backup to work you need to allow this user to write to the target directory. E.g. with `sudo chown -R USERNAME:GROUPNAME /mnt/backup`. The same applies when changing Nextcloud's datadir. E.g. `sudo chown -R USERNAME:GROUPNAME /mnt/ncdata`. When you want to use the NEXTCLOUD_MOUNT option for local external storage, you need to adjust the permissions of the chosen folders to be accessible/writeable by the userid `100032:100032` (if running `grep ^$(whoami): /etc/subuid` as the user that is running the docker daemon returns 100000 as first value).

 ## Run multiple AIO instances on the same server with docker rootless
 1. Create as many linux users as you need first. The easiest way is to use `sudo adduser` and follow the setup for that. Make sure to create a strong unique password for each of them and write it down!
 1. Log in as each of the users e.g. by opening a new SSH connection and install docker rootless for each of them by following step 0-4 of the [docker rootless documentation](./docker-rootless.md).
-1. Then install AIO in reverse proxy mode by using the command that is descriebed in step 2 and 3 of the [reverse proxy documentation](./reverse-proxy.md) but use a different `APACHE_PORT` and [`TALK_PORT`](https://github.com/nextcloud/all-in-one#how-to-adjust-the-talk-port) for each instance as otherwise it will bug out. Also make sure to adjust the docker socket and `DOCKER_SOCKET_PATH` correctly for each of them by following step 6 of the [docker rootless documentation](./docker-rootless.md). Additionally, modify `--publish 8080:8080` to a different port for each container, e.g. `8081:8080` as otherwise it will not work.<br>

 **⚠️ Please note:** If you want to adjust the `NEXTCLOUD_DATADIR`, make sure to apply the correct permissions to the chosen path as documented at the bottom of the [docker rootless documentation](./docker-rootless.md). Also for the built-in backup to work, the target path needs to have the correct permissions as documented there, too.
 1. Now install your webserver of choice on the host system. It is recommended to use caddy for this as it is by far the easiest solution. You can do so by following https://caddyserver.com/docs/install#debian-ubuntu-raspbian or below. (It needs to be installed directly on the host or on a different server in the same network).
 1. Next create your Caddyfile with multiple entries and domains for the different instances like described in step 1 of the [reverse proxy documentation](./reverse-proxy.md). Obviously each domain needs to point correctly to the chosen `APACHE_PORT` that you've configured before. Then start Caddy which should automatically get the needed certificates for you if your domains are configured correctly and ports 80 and 443 are forwarded to your server.

     - `--publish 8080:8080` This means that port 8080 of the container should get published on the host using port 8080. This port is used for the AIO interface and uses a self-signed certificate by default. You can also use a different host port if port 8080 is already used on your host, for example `--publish 8081:8080` (only the first port can be changed for the host, the second port is for the container and must remain at 8080).
     - `--publish 8443:8443` This means that port 8443 of the container should get published on the host using port 8443. If you publish port 80 and 8443 to the public internet, you can access the AIO interface via this port with a valid certificate. It is not needed if you run AIO behind a web server or reverse proxy and can get removed in that case as you can simply use port 8080 for the AIO interface then.
     - `--volume nextcloud_aio_mastercontainer:/mnt/docker-aio-config` This means that the files that are created by the mastercontainer will be stored in a docker volume that is called `nextcloud_aio_mastercontainer`. This line is not allowed to be changed, since built-in backups would fail later on.
-    - `--volume /var/run/docker.sock:/var/run/docker.sock:ro` The docker socket is mounted into the container which is used for spinning up all the other containers and for further features. It needs to be adjusted on Windows/macOS and on docker rootless. See the applicable documentation on this. If adjusting, don't forget to also set `DOCKER_SOCKET_PATH`!

 ### How to run AIO on Synology DSM
-On Synology, there are two things different in comparison to Linux: instead of using `--volume /var/run/docker.sock:/var/run/docker.sock:ro`, you need to use `--volume /volume1/docker/docker.sock:/var/run/docker.sock:ro` to run it. You also need to add `--env DOCKER_SOCKET_PATH="/volume1/docker/docker.sock"`to the docker run command of the mastercontainer (but before the last line `nextcloud/all-in-one:latest`). Apart from that it should work and behave the same like on Linux. Obviously the Synology Docker GUI will not work with that so you will need to either use SSH or create a user-defined script task in the task scheduler as the user 'root' in order to run the command.
