  If this is to be changed, it is expected that the database you wish to connect to is
  created manually.
* patch-storage.s3-access-key | string

  AWS programmatic API access key. Must be set together with patch-storage.s3-secret-key.
  When both are omitted, the AWS SDK's default credential chain is used instead. Note that
  this workload runs in a pod, not a VM, so ambient credentials (e.g. an EC2 instance role)

  separately for the workload's service account; otherwise, these keys must be set.
* patch-storage.s3-assume-role-arn | string

  but must be created manually.

  When using "filesystem", patches are stored at the path configured in
  patch-storage.filesystem-path.

  this is the sampling average of one blocking event per `BlockProfileRate` nanoseconds spent blocked. For example, set rate to 1000000000 (aka int(time.Second.Nanoseconds())) to record one sample per second a goroutine is blocked. It is recommended to set this to values greater than 10,000. For more info, visit this: https://github.com/DataDog/go-profiler-notes/blob/main/block.md#benchmarks

* profiler.mutex\_profile\_fraction | int

  Default: 5

  this turns on mutex profiles with rate indicating the fraction of mutex contention events reported in the mutex profile. On average, 1/rate events are reported. Setting an aggressive rate can hurt performance. ProfileMutexes must be True

  this will profile the memory for allocated space as well as allocated objects
* profiler.profile\_blocks | boolean

  would profile blocking events (channels, select, etc) with the BlockProfileRate frequency.

  Once the queue is reached, subsequent requests are rejected.
* server.concurrency-limit | int

  Default: 1000

  Maximum number of API requests being served concurrently.
* server.is-hosted | boolean

  Defines whether the server will act as an on-prem server
  (i.e. fetching patches from the hosted server), or will act as a
  hosted server.
* server.log-level | string

  Default: info

  The server's log level (e.g., debug, info, warning, error).
* server.redirect-downloads | boolean

  When true, the server will redirect downloads directed at its /v1/patches/{filename}
  endpoint to the endpoint defined in the server.url-template config option. This is
  useful if you want patch downloads to be redirected to a fileserver fronting patches.
  Note: Do not enable this option if the server.url-template is configured as the
  Livepatch-server as this will result in a redirect loop.
* server.url-template | string

  Template string to use when making URLs for giving back to the client.

  e.g. https://livepatch-hosting.com/v1/patches/{filename}

  This will need to be configured once the url or ip address of the service
