 As you do have Docker running as described before, you can easyly install a running Instance of Nextcloud to you PC. Heres the original doc: [[https://github.com/nextcloud/all-in-one|https://github.com/nextcloud/all-in-one]]
+===== Docker Network =====
+To have IPV6 support, Docker needs a local IPV6 Networkrange to use.
+So you need to edit the Dockers ~/.config/docker/daemon.json to be like this:
+Hint: If that file is missing, just create it.
+<file>
+{
+ "ipv6": true,
+ "fixed-cidr-v6": "fdff:6785:1::/48",
+ "iptables": true,
+ "ip6tables": true,
+ "log-opts": {
+  "max-size": "10m",
+  "max-file": "5"
+ }
+}
+</file>
 ===== Network preparations =====

 Per default, only ipv4 networking will be set up by nextcloud-aio. So the setup will check the adress and will fail.
-Further you need to have a network, that is called exactly "nextcloud-aio" with ipv6.

 ===== Docker Network driver =====
 There may be other problems with networking, so use another driver for networking like described here: [[https://github.com/nextcloud/all-in-one/issues/4621|https://github.com/nextcloud/all-in-one/issues/4621]]
+In general, the default slirp4netns- driver is: a. slow b. not able to uses ipv6 c. not able to do port forwarding, which maybe essential
+==== Pasta driver ====
+A quite new and high performance networking driver with good functionality is pasta.
+Pasta needs to be installed locally on the host ''zypper install pasta''
+After that, you need to change the systemd config für docker:
+<file>
+docker@pcserver2023:~> systemctl --user edit docker
+</file>
+and edit the file like this:
+<file>
+[Service]
+Environment="DOCKERD_ROOTLESS_ROOTLESSKIT_NET=pasta"
+Environment="DOCKERD_ROOTLESS_ROOTLESSKIT_PORT_DRIVER=implicit"
+Environment="DOCKERD_ROOTLESS_ROOTLESSKIT_FLAGS=--ipv6"
+</file>
+now do
+<file>
+docker@pcserver2023:~> systemctl daemon-reload
+docker@pcserver2023:~> systemctl --user stop docker
+docker@pcserver2023:~> systemctl --user start docker
+</file>
+You shold now have a fast network driver with port forwarding.
+===== Dockers Yaml =====
+In your Docker- Compose- Drirectory, create a new Directory called ''nextcloud_aoi'' and put the ''docker-compose.yml'' in it. You can finde some good documented example here: [[https://github.com/nextcloud/all-in-one/blob/main/compose.yaml|https://github.com/nextcloud/all-in-one/blob/main/compose.yaml]]
+Adjustements:
+  * For long Fileuploads, set NEXTCLOUD_MAX_TIME=3600 = one Hour to a higher value, like 14400 = four hours
+  * Also maybe NEXTCLOUD_UPLOAD_LIMIT=12G and
+  * maybe NEXTCLOUD_MEMORY_LIMIT=2048M
+===== AIO Webinterface =====
+It is important to understand, that the Docker- Service itself is NOT a working Nextcloud- Instance!
+The Service of this YML - called ''nextcloud-aio-mastercontainer'' is only a WEB- Interface to setup and maintain the Nextcloud- Services. Therefore it uses the Docker internal API, which is accessed by the Docker- Socket internally.
+So what you gain first, is a new Webserver on a seperate Port (default: 8080), wich will be the Administration Endpoint for you.
+**To access that Server from another PC, i STRONGLY DO NOT ADVISE to open the Firewall- Port of your Host and to make that service available to the internet!**
+Instead, you should use SSH Port Forwarding to administrate the Service. To have that, you maybe use ssh like this:
+<code>
+ssh -L 8080:IPofyoursshserver:8080 docker@NAMEofyoursshserver
+</code>
+After that, you can access the AIO- Mastercontainer WEB- GUI on [[https://localhost:8080|https://localhost:8080]]
+===== Caddy Service =====
+Now you need to add the Nextcloud- Service to you Caddyfile ( [[https://obel1x.de/dokuwiki/doku.php?id=content:serverbasics:docker-caddy#caddy_configuration|https://obel1x.de/dokuwiki/doku.php?id=content:serverbasics:docker-caddy#caddy_configuration]] )
+Add those lines First:
+<file>
+https://nextcloud.domain.tld:443 {
+       header Strict-Transport-Security max-age=31536000;
+#Large fileuploads
+       request_body {
+           max_size 10240M
+       }
+#       reverse_proxy nextcloud-aio-apache:11000
+#For install Domaincheck needed:
+       reverse_proxy nextcloud-aio-domaincheck:11000
+}
+</file>
+Mind, that when starting Nextcloud-AIO, the service nextcloud-aio-domaincheck will be setup. After installation has succeeded, the service will be shutdown and nextcloud-aio-apache will take over. On a Host, having rootful docker, this will work with localhost:11000 as destination, but not in rootless docker.
+So we need this small quirk to work around it.
+After you have setup the Configuration in Nextcloud, when installing and starting the Services, comment out that line and uncomment the apache- line. Than restart Caddy - you won't need that line again.
+===== Final Nextcloud- Setup =====
+Now, ssh on your Host and go to [[https://localhost:8080|https://localhost:8080]]
+and finish everything on that WEB- GUI. Mind, that installing the Services will take a long time. Don't panik if nothing seems to happen. Just let it do one hour or more.
+Enjoy your fully flagged Nextcloud.
+__**IMPORTANT**__  : You should install the Container [[https://github.com/nextcloud/all-in-one/tree/main/community-containers/borgbackup-viewer|https://github.com/nextcloud/all-in-one/tree/main/community-containers/borgbackup-viewer]]
+And read about Backups and restore VERY CAREFULLY here: [[:content:serverbasics:docker-backup#restore_and_userids_in_the_borg-backups|docker-backup]]
+The next step would now be to integrate Nextcloud with your IPA- Domain.
+===== Enable SSO to Logon with FreeIPA/Authentik =====
+Before proceeding, you should have integrated you Client to the domain as written in [[.:docker-freeipa|]] , you should be logged into your PC as freeipa- user.
+Than, check, that Authentik- Kerberos is working as described at [[.:docker-authentik|]] and that you can authenticate in Authentik only by using the Kerberos- Symbol at Authentik- Logon- Page.
+If this is working, check this docs to integrate Nextcloud with Authentik/SSO: [[https://docs.goauthentik.io/integrations/services/nextcloud/|https://docs.goauthentik.io/integrations/services/nextcloud/]]
+**Attention**: to have the UserID of FreeIPA be used by Nextcloud, i had to:
+   * In Authentik / Provider Nextcloud: under Advance Protocol Settings: Subject mode = Based on user's username
+  * And in ODIC- Settings of Nextcloud, use "sub" as userid-mapping.
+  * Turn off "Use unique Userids" and Turn on Group Provisioniong so that your Admins will become NC- Admins
+All other Settungs either made Admins not beeing Admins in NC or had hashed- userids in Nexctcloud, which make it complicated to get acces to NC with your PCs UserID.
+==== Disable User Logon-Screen ====
+After you can logon with authentik, disable the user-input screen by opening container shell of ''nextcloud-aio-nextcloud''  container and enter:
+<code>
+containerid:/var/www/html# sudo -u www-data php /var/www/html/occ config:app:set --value=0 user_oidc allow_multiple_user_backends
+</code>
+Remember, that you now need to go to
+''[[http://nextcloud.domain.tld/login?direct=1|http://nextcloud.domain.tld/login?direct=1]]''
+to logon to nextcloud with the local admin.
