This PR cleans up the docs in a way to make them simpler to ingest by our [docs repo](https://gitea.com/gitea/gitea-docusaurus). 1. It includes all of the sed invocations our ingestion did, removing the need to do it at build time. 2. It replaces the shortcode variable replacement method with `@variable@` style, simply for easier sed invocations when required. 3. It removes unused files and moves the docs up a level as cleanup. --------- Signed-off-by: jolheiser <john.olheiser@gmail.com>

# Storage
|
|
|
|
This document describes the storage of the package registry and how it can be managed.
|
|
|
|
## Deduplication
|
|
|
|
The package registry has a build-in deduplication of uploaded blobs.
|
|
If two identical files are uploaded only one blob is saved on the filesystem.
|
|
This ensures no space is wasted for duplicated files.
|
|
|
|
If two packages are uploaded with identical files, both packages will display the same size but on the filesystem they require only half of the size.
|
|
Whenever a package gets deleted, only the references to the underlying blobs are removed.
|
|
The blobs get not removed at this moment, so they still require space on the filesystem.
|
|
When a new package gets uploaded the existing blobs may get referenced again.
|
|
|
|
These unreferenced blobs get deleted by a [clean up job](administration/config-cheat-sheet.md#cron---cleanup-expired-packages-croncleanup_packages).
|
|
The config setting `OLDER_THAN` configures how long unreferenced blobs are kept before they get deleted.
|
|
|
|
## Cleanup Rules
|
|
|
|
Package registries can become large over time without cleanup.
|
|
It's recommended to delete unnecessary packages and set up cleanup rules to automatically manage the package registry usage.
|
|
Every package owner (user or organization) manages the cleanup rules which are applied to their packages.
|
|
|
|
|Setting|Description|
|
|
|-|-|
|
|
|Enabled|Turn the cleanup rule on or off.|
|
|
|Type|Every rule manages a specific package type.|
|
|
|Apply pattern to full package name|If enabled, the patterns below are applied to the full package name (`package/version`). Otherwise only the version (`version`) is used.|
|
|
|Keep the most recent|How many versions to *always* keep for each package.|
|
|
|Keep versions matching|The regex pattern that determines which versions to keep. An empty pattern keeps no version while `.+` keeps all versions. The container registry will always keep the `latest` version even if not configured.|
|
|
|Remove versions older than|Remove only versions older than the selected days.|
|
|
|Remove versions matching|The regex pattern that determines which versions to remove. An empty pattern or `.+` leads to the removal of every package if no other setting tells otherwise.|
|
|
|
|
Every cleanup rule can show a preview of the affected packages.
|
|
This can be used to check if the cleanup rules is proper configured.
|
|
|
|
### Regex examples
|
|
|
|
Regex patterns are automatically surrounded with `\A` and `\z` anchors.
|
|
Do not include any `\A`, `\z`, `^` or `$` token in the regex patterns as they are not necessary.
|
|
The patterns are case-insensitive which matches the behaviour of the package registry in Gitea.
|
|
|
|
|Pattern|Description|
|
|
|-|-|
|
|
|`.*`|Match every possible version.|
|
|
|`v.+`|Match versions that start with `v`.|
|
|
|`release`|Match only the version `release`.|
|
|
|`release.*`|Match versions that are either named or start with `release`.|
|
|
|`.+-temp-.+`|Match versions that contain `-temp-`.|
|
|
|`v.+\|release`|Match versions that either start with `v` or are named `release`.|
|
|
|`package/v.+\|other/release`|Match versions of the package `package` that start with `v` or the version `release` of the package `other`. This needs the setting *Apply pattern to full package name* enabled.|
|
|
|
|
### How the cleanup rules work
|
|
|
|
The cleanup rules are part of the [clean up job](administration/config-cheat-sheet.md#cron---cleanup-expired-packages-croncleanup_packages) and run periodically.
|
|
|
|
The cleanup rule:
|
|
|
|
1. Collects all packages of the package type for the owners registry.
|
|
2. For every package it collects all versions.
|
|
3. Excludes from the list the # versions based on the *Keep the most recent* value.
|
|
4. Excludes from the list any versions matching the *Keep versions matching* value.
|
|
5. Excludes from the list the versions more recent than the *Remove versions older than* value.
|
|
6. Excludes from the list any versions not matching the *Remove versions matching* value.
|
|
7. Deletes the remaining versions.
