An implementation of the `storagedriver.StorageDriver` interface which uses the local filesystem.

## Parameters

|
|
|
|
|
2017-08-22 23:25:51 +00:00
|
|
|
* `rootdirectory`: (optional) The absolute path to a root directory tree in which
|
2016-09-28 21:46:28 +00:00
|
|
|
to store all registry files. The registry stores all its data here so make sure
|
2018-03-22 17:12:29 +00:00
|
|
|
there is adequate space available. Defaults to `/var/lib/registry`. If the directory
|
2020-10-13 09:59:31 +00:00
|
|
|
does not exist, it will be created honoring [`umask`](https://man7.org/linux/man-pages/man2/umask.2.html)
|
2018-03-22 17:12:29 +00:00
|
|
|
bits. If `umask` bits are not set, the resulting permission will be `0777`.
|
2017-08-22 23:25:51 +00:00
|
|
|
* `maxthreads`: (optional) The maximum number of simultaneous blocking filesystem
|
2016-09-28 21:46:28 +00:00
|
|
|
operations permitted within the registry. Each operation spawns a new thread and
|
|
|
|
|
may cause thread exhaustion issues if many are done in parallel. Defaults to
|
2017-06-20 18:01:52 +00:00
|
|
|
`100`, and cannot be lower than `25`.
