+Docker is a powerful solution for setting up Services. This short Introducion will give you hints how to setup Docker in a good way in userspace, so no root-access is needed for Docker.
-Currently i am Experimenting on that topic, so maybe this documentation will be ready to use, maybe not.
+Currently i am experimenting on that topic, so maybe this documentation will be ready to use, maybe not.
-===== Docker rootless =====
 Docker itself is nice, but it will run as root per default, which is a no-go at all. This will setup Docker in rootless- mode on OpenSuSE (currently Leap 15.5).
-==== Package ====
+__**Warning: This is a very strong advise NOT to use docker default in rootmode at all! **__  The reason is, that any service is able to talk to the Docker Daemon if there is a connection to the Docker socket in the Volumes (which some services require) - or simply if thers a bug somewhere. By that way, the Docker Container will be able to set up ANY service and bind ANY location on the Host, that the docker user may be able to see. So if the Service gets taken over and the service ist runnig as root… you know where you are.
-While Docker-Rootless is not in the main Repositories, first add the AddOn- Repository: ''[[https://download.opensuse.org/repositories/Virtualization:/containers/${releasever}/|https://download.opensuse.org/repositories/Virtualization:/containers/${releasever}/]]''
+So just: Don't set up Docker rootfull at all if possible - its even not neeeded nowadays.
-Then install the package ''docker-rootless-extras'' and its dependencies.
+===== Filesystem Layout =====
-==== User ====
-Create a new user and maybe give this user another home-directory, as it will store all files of docker.
+Mind, that at the time writing, ''overlay2'' is the way to go as storage driver in docker, but it only supports xfs as backing filesystems (with ''d_type=true'' which means ''ftype=1'' ) for full support.
-Let's say choose home ''/srv/docker-user ''for user ''docker''.
+I personally dislike xfs, especially while its not rubust and won't shrink. I use it anyway, because of its srong advise to do so - with kernel 5.19+ it should be possible to get overlay2 working on btrfs, but still there are things that may not work even with that kernel - in the worst case, docker is unable to unlink files, so there will be huge Containers and Volumes and maybe Services will break.
-Also it may be a good choice, not to have this user added to ''users'' group - choose ''docker'' as default group.
+So make sure, that the Home-Directory of you docker user is on XFS. The ftype is already ok on SuSE 15.5, check output of ''xfs_info <volumename>''.
-==== Install rootless Docker ====
-Warning: You CANNOT sudo to this user and install docker this way, because pam is not loaded when doing this. You need to:
+Warning: you may have umask set your way - i prefer 007 as written before. But if you change umask and permissions be very cautious, as docker uses userid- mapping and may change the permissions and ownersets of files in its directory to the subuserid.
+That may change the ownership in a way, that even the docker user on the host cannot access the Files, which is OK !
+__**STRONG WARNING: Don't change permissions or ownership of docker- directories on the Host directly as this will change them in the container, making them unavaiable and break your Services !!!**__
+__**The only way to manage Volume- File- Permissions is to bash inside the running container itself and to change them there (to the right values of course)!**__
+A short hint: Docker rootless uses Sub(g)uids, which is a feature of Linux. That means each user has a range of userids (quite a huge range) and groupid which the user may use. Those will be exclusive reserved for that user. But it does not mean, that the User can acces the Files created by those Subuids! Also the UIDs are onyl a number - not a real user in Linux having a username- They cannot be used to logon or to work with. Docker manages internally which Host-Subuserid is assigned to which caontainer and to which userid inside the running container/service. Inside the Container, you may become that user having a real username and a (different) uid.
+===== Packages NOT to install =====
+I had really a lot of troubles with the package Docker-Rootless in the AddOn- Repository: ''[[https://download.opensuse.org/repositories/Virtualization:/containers/${releasever}/|https://download.opensuse.org/repositories/Virtualization:/containers/${releasever}/]]'' while they are not installing docker the same way, that docker would do. For example they will not be installed in User-Subspace only, but will use systems Docker executables installed in global paths. This is a problem when using btrfs - as btrfs is not fully compatible with docker. So i won't use this any more.
+So i disabled the following packages and locked them to never install:
+  * docker
+  * docker-compose
+  * containerd
+Check out beneath for install the docker way.
+===== Docker- User =====
+Create a new **group**  called **docker**  and a new **user**  called **docker**. Make the user is in the **default group docker**.
+Attention: The Home Directory should be on a volume having XFS as btrfs or others are not fully supported right now (20.04.2024 - patches in new Kernel 5.19 are incoming, but this Kernel is not released until now and still there are some problems open in developement there).
+===== cGroups v2 =====
+OpenSuSE Leap 15.5 does not have cGroups v2 enabled, which are needed by docker.
+You may see a warning (later) when running ''docker info'':
+''WARNING: Running in rootless-mode without cgroups. To enable cgroups in rootless-mode, you need to boot the system in cgroup v2 mode.''
+According to this documentation [[https://rootlesscontaine.rs/getting-started/common/cgroup2/|https://rootlesscontaine.rs/getting-started/common/cgroup2/]] it needs to be enabled by appending the yast/bootloader command line with:
+''systemd.unified_cgroup_hierarchy=1''
+and also the delegation for the user of cpu is needed:
 <file>
+$ sudo mkdir -p /etc/systemd/system/user@.service.d
+$ cat <<EOF | sudo tee /etc/systemd/system/user@.service.d/delegate.conf
+[Service]
+Delegate=cpu cpuset io memory pids
+EOF
+$ sudo systemctl daemon-reload
+</file>
+after this, reboot and check if ''/sys/fs/cgroup/cgroup.controllers''  is present
+After installing docker (see beneath), check if ''docker info''  says:
+<file>
+Cgroup Driver: systemd
+Cgroup Version: 2
+</file>
+Than, its fine.
+===== Install rootless Docker =====

+==== Additional knowledge ====
+  * Storage driver and FS-Type : overlay2 should always be used, btrfs is outdated! XFS and d_type are important!
+  * CGroup Version needs to be 2 or better
+  * If you see Docker complaining about Module aufs at start: do not care about - that module is obsolete
+===== IP-Filter =====

+level=info msg="skipping firewalld management for rootless mode"

+You first need to load the module with modprobe.
+For system startup, use ''/etc/modules-load.d''  and creat e a file ''docker-rootless.conf''  in it, containing that module.

+Notice: Don't use ''userns-remap''  - this won't work and makes no sense in rootless!
+Edit: "experimental": true has been removed for ipv6 with docker v27.
-===== Filesystem Layout =====
+You need to adjust cidr to some unique ULA. ULAs are non internet routable adresses (like 192.X.X.X in ipv4). Select an unique adress only for that internal Docker network - you can choose anything that is not assigned anywhere else on your network to not cause trouble.
-Mind, that at the time writing ''overlay2'' is the way to go as storage driver in docker, but it only supports xfs as backing filesystems (with ''d_type=true'' which means ''ftype=1'' ).
+Maybe use this tool to generate: [[https://www.unique-local-ipv6.com|https://www.unique-local-ipv6.com]]
-For checking which filesystem is in use, see ''docker info'', lines under ''Storage Driver'':
+===== Networking in Docker rootless =====
-<file>
-Storage Driver: overlay2
- Backing Filesystem: xfs
- Supports d_type: true
- Using metacopy: false
- Native Overlay Diff: false
- userxattr: true
-</file>
+If you read docs in the net about networking with Docker you may see docker0 as bridge network. While this network is also there in docker rootless, you will not find that network as interface on your host like you would on a rootful docker.
-If you create a XFS-Filesystem with Leap 15.5 it will have ''ftype=1'' set, check output of ''xfs_info <volumename>''
+Instead the network is encapsulated in the environement of rootlesskit and not visible to the host. From the Hosts view Docker is just another Application running on your Host talking to the internet like some app would do.
-For me, i like btrfs a bit more than xfs, so i chose to have three different locations for docker on two filesystems (which are raided lvms. Check out the other docs here):
+===== Install docker compose =====
-<file>

+The command ''docker-compose''  has been obsoleted and been replaced by a plugin ''compose''  for docker (see [[https://docs.docker.com/compose/install/|https://docs.docker.com/compose/install/]]).

-Unfortunatelly, docker does not care about linux acls and user permissions - or to be more precise: it overwrites them.
+Your done with the compose plugin
-So if you would like to have your files really secured from other user, you can create the volume with an umask - e.g.:
+===== Update =====
-''docker volume create portainer_data –opt o=umask=0007'' \\
+If you want to update your docker- installation, there is not update- process but to use the same script again:
-That would make all files in the Volume have the right permissions.
-In Docker-Compose use this in your yml:
+<file>
+#!/bin/bash
+#Upgrade docker rootless and plugin
+./docker_stop_all.sh
+sleep 5
+systemctl --user stop docker
+sleep 5
+#uninstall
+rm -f ~/bin/dockerd
+rm ~/.config/systemd/user/docker.service.bak
+mv ~/.config/systemd/user/docker.service ~/.config/systemd/user/docker.service.bak
+#reinstall docker compose
+COMPOSE_VER='2.32.4'
+rm $DOCKER_CONFIG/cli-plugins/docker-compose
+echo "Download Docker Compose Release ${COMPOSE_VER} - please check at https://github.com/docker/compose/releases for the newes Version and change this File"
+curl -SL https://github.com/docker/compose/releases/download/v${COMPOSE_VER}/docker-compose-linux-x86_64 -o $DOCKER_CONFIG/cli-plugins/docker-compose
+chmod +x $DOCKER_CONFIG/cli-plugins/docker-compose
+#install docker
+curl -fsSL https://get.docker.com/rootless | sh
+#need to give the new binary permissions to acces privileged network ports (beneath 1024)
+sudo setcap 'cap_net_bind_service=+ep' ~/bin/rootlesskit
+#this should be everything

-volumes:
-  volumename:

-Device and type need to be there, but can be empty to use default values.
+===== Create a place for Yamls =====
-===== First Docker App: Portainer =====
+Now, that you have compose, you can use it to setup your services with YAML- Files. Each service should have a directory for its own.
-Now - finally its time for our first running Container. As the Portainer- App is the most important Management- Software in Docker, let's run it in a safe userspaced way now.
+Make a directory with ''mkdir ~/docker_compose''  and change to it.
-As always, SSH into your docker- user and than create the folders and yml-files for portainer.
