Just tripped into that one: I upgraded a Rancher host to `0.4.5`,
|
||||
rebooted it & somehow only the `system-docker` daemon came up.
|
||||
|
||||
The user facing container was stuck in a reboot loop:
|
||||
|
||||
```

Check your `/var/log/docker.log` see if you are running into
|
||||
[#18283](https://github.com/docker/docker/issues/18283):
|
||||
|
||||
```
|
||||
Error starting daemon: Error initializing network controller: could not delete the default bridge network: network bridge has active endpoints.
|
||||
```
|
||||
|
||||
The solution was fairly easy:
|
||||
|
||||
``` bash
|
||||
$ sudo rm -r /var/lib/docker/network; sudo reboot;
|
||||
```
|
||||
