Livepatch on-prem patch storage
Livepatch server supports several different drivers for storing patch files downloaded from livepatch.canonical.com:
- Local filesystem
- Swift
- S3 (and compatible implementations, e.g. minio)
- Postgresql
The filesystem patch store is easiest to deploy and suits most configurations. However, if there is a need to scale out the livepatch server such as have multiple livepatch servers running to handle the load, the filesystem patch store should not be used.
In case there is a need to scale out livepatch on-prem, use the s3, postgresql or swift patch stores. Any patch store should have enough space for storing livepatches - currently at least 45GB for all patches, see this guide to filter patches sent to your on-prem instance to specific kernel variants/architectures and lower this requirement.
See the patch storage config for all available parameters.
