## Syntax

`<value>`

* If specified, will set the config value associated to this key.&#x20;

  **default** : info

* `max-package-cache-size` \[number] The maximum disk space to use for the package cache, in Bytes.\
  Only apply if the package cache is enabled (`package-cache-enabled` configuration key set to `true`). **default** : 2GB
* `package-cache-enabled` \[boolean] Indicates whether the package cache should be enabled.\
  Enabling the package cache will lead to faster Containers generation, given that all packages versions used for a Container generation, will be retrieved from the cache if available rather than being downloaded upon every generation. **default** : true
