If you are experiencing errors when installing [Gluu](https://gluu.org/), the Open Source digital identity server in LXD, this is because Gluu works in a chrooted environment by default. Errors like these should appear on systems with deb or RPM packages installed:
|
||
|
|
|
||
|
|
```log
|
||
|
|
Jun 03 14:05:10 gluu systemd[1]: Starting Container gluu-server...
|
||
|
|

|

```

To resolve the problem, the container must be privileged and nesting must be enabled. The same profile settings are required for Docker and nested LXD containers:
|
||
|
|
|
||
|
|
```json
|
||
|
|
security.nesting: "true"
|
||
|
|
security.privileged: "true"
|
||
|
|
```
|
||
|
|
|
||
|

It's a Java application. In some cases, it may also require tunning of the kernel ulimits!
