Urbit Harbor is a supervisor for Urbit ships on the local machine. It does no
orchestration, it just manages systemd services.
Setup process:
<running as user "urbit-harbor">
dir=/var/urbit/harbor
urbit -c $dir/zod -k $dir/zod.key -x # one-time setup
<create $dir/zod.service from some template>
systemctl --user enable $dir/zod.service # nees fullpath
systemctl --user start zod.service
Service Template:
[Service]
ExecStart=urbit -tq /var/urbit/harbor/zod # maybe want -d?
ExecStartPre=mkdir -p /var/urbit/harbor/zod
[Unit]
Description=zod
[Install]
WantedBy=multi-user.target
TODO:
- use systemd.resource-control to limit memory/CPU for ships
- Urbit.Cloud controller will set different limits by reading/editing the
ini file, and change price to customer
- figure out what firewall stuff i need to do
