== Running The Config Server Using Git In A Container
If you are getting a `java.io.IOException` when running the Config Server in a container that is similar to:
```
2022-01-03 20:04:02,892 [tributeWriter-2] ERROR org.eclipse.jgit.util.FS$FileStoreAttributes.saveToConfig - Cannot save config file 'FileBasedConfig[/.config/jgit/config]'
java.io.IOException: Creating directories for /.config/jgit failed
```
You must either:
1. Provide a user with a writeable home directory inside the container.
2. Set the environment variable `XDG_CONFIG_HOME` inside the container to point to a directory where the Java process has write permissions.
