All applications and listeners lost after restarting unitd

[k4ml]

sudo curl --unix-socket /var/run/control.unit.sock http://localhost/
{
	"listeners": {
		"*:8300": {
			"application": "hello"
		}
	},

	"applications": {
		"hello": {
			"type": "python",
			"workers": 2,
			"module": "wsgi",
			"user": "ubuntu",
			"group": "ubuntu",
			"path": "/home/ubuntu/unit/hello"
		}
	}
}

After restarting with sudo systemctl restart unitd:-

sudo curl --unix-socket /var/run/control.unit.sock http://localhost/
{
	"listeners": {},
	"applications": {}
}

So I have to add it again:-

sudo curl -X PUT -d @hello.json --unix-socket /var/run/control.unit.sock http://localhost/

I have the same issue, also on ubuntu xenial and unit installed from apt.

You should manually save and restore unitd configuration by call "dumpconfig" and "restoreconfig" service subcommands.
If you do not want to lose configuration after restart, try this:

sudo service unitd dumpconfig
sudo service unitd restart
sudo service unitd restoreconfig

Configuration stores in /etc/unit/config

[VBart]

Currently configuration is not persistent across reloads and expected to be loaded each time. The patches to make it persistent is on review.

[VBart]

Implemented in 4953e5b.

your document should update .

[docteurklein]

so do we still have to use dumpconfig and restoreconfig after 4953e5b ? or is running unitd --state enough?

[binnn6]

Now the config is persistent through restart. --state is just for where u want to store the config file ,if
no -- state, it will be stored as build/conf.json by default.

[docteurklein]

thanks. and this config.json structure is exactly the same as the one you PUT on the control socket?

[binnn6]

Yes.

[VBart]

@docteurklein While currently it's the same, it doesn't have to in the future. The content of "store" directory doesn't supposed to be editable by user. It's an internal storage for unit daemon.

[docteurklein]

ok, that's good to know, thanks! I'm currently trying to make a docker container that starts a ready to go unitd, without having to curl the config at runtime. it's not very immutable infra otherwise.
