type ServiceName = String Source
type MachineName = String Source
started :: ServiceName -> Property NoInfo Source
Starts a systemd service.
stopped :: ServiceName -> Property NoInfo Source
Stops a systemd service.
enabled :: ServiceName -> Property NoInfo Source
Enables a systemd service.
disabled :: ServiceName -> Property NoInfo Source
Disables a systemd service.
restarted :: ServiceName -> Property NoInfo Source
Restarts a systemd service.
persistentJournal :: Property NoInfo Source
Enables persistent storage of the journal.
configured :: FilePath -> Option -> String -> Property NoInfo Source
Ensures that an option is configured in one of systemd's config files. Does not ensure that the relevant daemon notices the change immediately.
This assumes that there is only one [Header] per file, which is currently the case. And it assumes the file already exists with the right [Header], so new lines can just be appended to the end.
journaldConfigured :: Option -> String -> Property NoInfo Source
Configures journald, restarting it so the changes take effect.
daemonReloaded :: Property NoInfo Source
Causes systemd to reload its configuration files.
container :: MachineName -> (FilePath -> Chroot) -> Container Source
Defines a container with a given machine name.
Properties can be added to configure the Container.
container "webserver" (Chroot.debootstrapped (System (Debian Unstable) "amd64") mempty) & Apt.installedRunning "apache2" & ...
nspawned :: Container -> RevertableProperty Source
Runs a container using systemd-nspawn.
A systemd unit is set up for the container, so it will automatically be started on boot.
Systemd is automatically installed inside the container, and will communicate with the host's systemd. This allows systemctl to be used to examine the status of services running inside the container.
When the host system has persistentJournal enabled, journactl can be used to examine logs forwarded from the container.
Reverting this property stops the container, removes the systemd unit, and deletes the chroot and all its contents.
containerCfg :: String -> RevertableProperty Source
This configures how systemd-nspawn(1) starts the container, by specifying a parameter, such as "--private-network", or "--link-journal=guest"
When there is no leading dash, "--" is prepended to the parameter.
Reverting the property will remove a parameter, if it's present.
resolvConfed :: RevertableProperty Source
Bind mounts /etc/resolv.conf from the host into the container.
This property is enabled by default. Revert it to disable it.
