Pascal Bach 22acfd0327 docker service: add option to do automatic pruning
This allows to run the prune job periodically on a machine.
By default the if enabled the job is run once a week.

The structure is similar to how system.autoUpgrade works.

docker: fix socket permissions
Docker socket is world writable. This means any user on the system is
able to invoke docker command. (Which is equal to having a root access
to the machine.)

This commit makes socket group-writable and owned by docker group.

Jörg Thalheim c23032a8b1 docker: update service units from upstream
All the new options in detail:

Enable docker in multi-user.target make container created with restart=always
to start. We still want socket activation as it decouples dependencies between
the existing of /var/run/docker.sock and the docker daemon. This means that
services can rely on the availability of this socket. Fixes #11478 #21303

  wantedBy = ["multi-user.target"];

This allows us to remove the postStart hack, as docker reports on its own when
it is ready.

  Type=notify

The following will set unset some limits because overhead in kernel's ressource
accounting was observed. Note that these limit only apply to containerd.
Containers will have their own limit set.

  LimitNPROC=infinity
  LimitCORE=infinity
  TasksMax=infinity

Upgrades may require schema migrations. This can delay the startup of dockerd.

  TimeoutStartSec=0

Allows docker to create its own cgroup subhierarchy to apply ressource limits on
containers.

  Delegate=true

When dockerd is killed, container should be not affected to allow
`live restore` to work.

  KillMode=process

Jaka Hudoklin 5d9c62541a docker module: updates
- logDriver option, use journald for logging by default
- keep storage driver intact by default, as docker has sane defaults
- do not choose storage driver in tests, docker will choose by itself
- use dockerd binary as "docker daemon" command is deprecated and will be
  removed
- add overlay2 to list of storage drivers

Benno Fünfstück 3850123f32 nixos/docker: use wrapped modprobe
We need to use wrapped modprobe, so that it finds the right
modules. Docker needs modprobe to load overlay kernel module
for example.

This fixes an an error starting docker if the booted system's kernel
version is different from the /run/current-system profile's one.

Benno Fünfstück 79b4e5a8d7 docker module: fix kernel module loading
The docker module used different code for socket-activated docker daemon than for the non-socket activated daemon.
In particular, if the socket-activated daemon is used, then modprobe wasn't set up to be usable and in PATH for
the docker daemon, which resulted in a failure to start the daemon with overlayfs as storageDriver if the
`overlay` kernel module wasn't already loaded. This commit fixes that bug (which only appears if socket
activation is used), and also reduces the duplication between code paths so that it's easier to keep
both in sync in future.

Bjørn Forsman 5f17aeb403 nixos/docker: default storageDriver to "devicemapper"
Commit 9bfe92ecee ("docker: Minor improvements, fix failing test") added
the services.docker.storageDriver option, made it mandatory but didn't
give it a default value. This results in an ugly traceback when users
enable docker, if they don't pay enough attention to also set the
storageDriver option. (An attempt was made to add an assertion, but it
didn't work, possibly because of how "mkMerge" works.)

The arguments against a default value were that the optimal value
depends on the filesystem on the host. This is, AFAICT, only in part
true. (It seems some backends are filesystem agnostic.) Also, docker
itself uses a default storage driver, "devicemapper", when no
--storage-driver=x options are given. Hence, we use the same value as
default.

Add a FIXME comment that 'devicemapper' breaks NixOS VM tests (for yet
unknown reasons), so we still run those with the 'overlay' driver.

Closes #10100 and #10217.

Casey Ransom 791b600aac nixos/docker: Include ZFS commands in PATH for ZFS storagedriver
When using the ZFS storagedriver in docker, it shells out for the ZFS
commands. The path configuration for the systemd task does not include
ZFS, so if the driver is set to ZFS, add ZFS utilities to the PATH.

This will resolve https://github.com/NixOS/nixpkgs/issues/10127

Mateusz Kowalczyk 23187c3431 docker: allow the user to override postStart
My use-case: passing -H SOM.EIP.ADD.RES:PORT doesn't result in a .sock
file so the service would never go up.

Paul Colomiets 9bc1676e5a Upgrade docker to 1.1.2 and add docker module
This version of module has disabled socketActivation, because until
nixos upgrade systemd to at least 214, systemd does not support
SocketGroup. So socket is created with "root" group when
socketActivation enabled. Should be fixed as soon as systemd upgraded.

Includes changes from #3015 and supersedes #3028
