Upman

UPdata MANager is used in conjunction with Upclid to display pending updates and reboots.

Working features

displaying pending updates
displaying pending reboots
displaying locked packages
display log of last update-run
authenticating users via ldap (for actions, displaying works without login)
authorizing users via ldap (simple group check)
showing custom facts about systems (if custom facts are implemented)
triggering updates runs
triggering reboots
panic button (abort all updates/reboot, that have not been started)
optionally save ets tables to disk on shutdown (for hot cache / persistent persmissions&locks)

(un)locking packages
instead of authenticating clients: update-clearance includes list of reported updatetable packages. client only installs updates, if list matches.

Install current erlang (i.e. from here
copy upman.service to /etc/systemd/system/upman.service
copy upman.toml to /etc/upman.toml and customize the ldap settings, port, etc.
run mix deps.get to install dependencies
run mix phx.digest to create compressed assets
run MIX_ENV=prod mix release to create a release-package
run tar -C /opt/upman -xzf _build/prod/upman-$version.tar.gz to install the release locally
Start Upman via systemctl start upman
install and start Upclid on one or more systems
