juju uninstalling itself upon machine creation ?

[Junien F]

Hi,

I just deployed 4 new juju units (juju 2.4.7 agent on 2.5.0 controller), and 2 of them got stuck in "allocating". When I connected, this is what I found in the machine log :

https://pastebin.canonical.com/p/HNYXNTKPF5/

Most important lines :
2019-02-15 15:29:51 INFO juju.api apiclient.go:603 connection established to "wss://<IP>:17070/model/235f7c2f-b531-46e1-8438-1a663a614a68/api"
2019-02-15 15:29:51 DEBUG juju.worker.apicaller connect.go:155 [235f7c] failed to connect
2019-02-15 15:29:51 DEBUG juju.worker.dependency engine.go:582 "api-caller" manifold worker stopped: [235f7c] "machine-18" cannot open api: connection permanently impossible
2019-02-15 15:29:51 INFO juju.agent uninstall.go:36 marking agent ready for uninstall

Why does juju decide to uninstall itself ? If there's a good reason for that, it should at least notify the controller (or the controller should be able to notice somehow). Also, no connection is ever "permanently impossible", so juju should be able to retry.

Thanks

'permanently impossible' is a case where we were able to successfully
connect to a controller, but when we try to login with the credentials we
have, we are told that those credentials are not valid.
I believe the teardown existed for the manual provider case, if you had a
machine that was down, and the controller was destroyed, it wouldn't clean
up until the machine started again. We can certainly reevaluate the
position.
