title: 'Storage settings'
license: 'CC-BY-SA-4.0'

The storage for each subsystem is defined in `app.ini`. It can either
be on disk (`local` which is the default) or using a S3 compatible
server (`minio`). In both cases each subsystem stores all files (or
objects in the S3 parlance) in a dedicated directory as shown in the
table below:
| subsystem | directory | app.ini sections |
| ------------------- | ------------------ | --------------------- |
| Attachments | attachments/ | [attachment] |
| LFS | lfs/ | [lfs] |
| Avatars | avatars/ | [avatar] |
| Repository avatars | repo-avatars/ | [repo-avatar] |
| Repository archives | repo-archive/ | [repo-archive] |
| Packages | packages/ | [packages] |
| Actions logs | actions_log/ | [storage.actions_log] |
| Actions Artifacts | actions_artifacts/ | [actions.artifacts] |
For instance:
- if the `STORAGE_TYPE` is `local` and `APP_DATA_PATH` is
`/appdata`, the default directory to store attachments is
`/appdata/attachments`
- if the `STORAGE_TYPE` is `minio`, the
default directory to store attachments within the `MINIO_BUCKET`
bucket will be `attachments/`.
## Changing the storage for all subsystems
The `[storage]` section can be used to modify the storage of all
subsystems. The default is to use `local` storage under
`APP_DATA_PATH` and is equivalent to writing the following in `app.ini`:
```
[server]
APP_DATA_PATH = /forgejo/data
[storage]
STORAGE_TYPE = local
PATH = /forgejo/data
```
### Using local
For `local` storage, the `[storage]` section can only be used to
change the path under which all subsystems directories will be
created, using the `PATH` settings with an absolute pathname.
For instance:
```
[storage]
STORAGE_TYPE = local
PATH = /mystorage
```
will change the default for storing attachments to
`/mystorage/attachments`, LFS to `/mystorage/lfs` etc.
### Using minio
The `[storage]` section can be used to change the default storage type
used by all subsystems to `minio`.
For instance:
```
[storage]
STORAGE_TYPE = minio
MINIO_ENDPOINT = 127.0.0.1:9000
MINIO_ACCESS_KEY_ID = [redacted]
MINIO_SECRET_ACCESS_KEY = [redacted]
MINIO_BUCKET = forgejo
MINIO_LOCATION = us-east-1
```
will change the default for storing attachments to `attachments/` in
the `forgejo` bucket, LFS to `lfs/` in the `forgejo` bucket etc.
> **NOTE:** `MINIO_BASE_PATH` must not be set in the `[storage]` section.
The configuration option `MINIO_USE_SSL` defaults to `false` to maintain compatibility with locally hosted MinIO instances. If an external S3 provider is intended to be used, this option should be set to `true`.
For instance, assuming a MinIO instance at `https://minio.example.com`:
```
[storage]
STORAGE_TYPE = minio
MINIO_USE_SSL = true
MINIO_ENDPOINT = minio.example.com
MINIO_ACCESS_KEY_ID = [redacted]
MINIO_SECRET_ACCESS_KEY = [redacted]
MINIO_BUCKET = bucket
MINIO_LOCATION = us-east-1
```
## Storage settings for a single subsystem
It is possible to configure some subsystems to use S3 storage and others to use local
storage by adding settings to their respective sections. For instance:
```
[attachment]
PATH = /otherstorage/attachments
[lfs]
STORAGE_TYPE = minio
MINIO_BASE_PATH = lfs/
MINIO_ENDPOINT = 127.0.0.1:9000
MINIO_ACCESS_KEY_ID = [redacted]
MINIO_SECRET_ACCESS_KEY = [redacted]
MINIO_BUCKET = forgejo
MINIO_LOCATION = us-east-1
```
will store attachments in the local directory
`/otherstorage/attachments` while `lfs` files will be stored in the S3
server within the `lfs/` directory of the `forgejo` bucket.
## Storage settings
The value of `STORAGE_TYPE` can be `local` (the default) for file
system directories or `minio` for S3 servers. Each storage type has
its own settings, as explained below.
### Using local
There is just one setting when the `STORAGE_TYPE` is set to `local`:
`PATH`. It must be an absolute path and is interpreted as follows.
In the `[storage]` section, `PATH` is the path under which the
directories of each subsystem will be created instead of
`APP_DATA_PATH`. For instance, if `APP_DATA_PATH` equals `/appdata`
```
[storage]
STORAGE_TYPE = local
PATH = /mystorage
```
will create attachments in `/mystorage/attachments` instead of
`/appdata/attachments`, LFS files in `/mystorage/lfs` instead of
`/appdata/lfs`, etc.
In the section dedicated to a subsystem (see the table in the introduction), `PATH`
is the base path under which all files will be stored. For instance:
```
[storage]
STORAGE_TYPE = local
PATH = /mystorage
[attachment]
STORAGE_TYPE = local
PATH = /otherstorage/attachments
```
will store attachments in `/otherstorage/attachments` while `lfs`
files will be stored in `/mystorage/lfs`.
### Using minio
When the `STORAGE_TYPE` is set to `minio`, the settings are used to to
connect to a S3 compatible server:
- `SERVE_DIRECT`: **false**: Allows the storage driver to redirect to authenticated URLs to serve files directly. Only supported via signed URLs.
- `MINIO_ENDPOINT`: **localhost:9000**: S3 endpoint to connect.
- `MINIO_ACCESS_KEY_ID`: S3 accessKeyID to connect.
- `MINIO_SECRET_ACCESS_KEY`: S3 secretAccessKey to connect.
- `MINIO_BUCKET`: **forgejo**: S3 bucket to store the data.
- `MINIO_BUCKET_LOOKUP`: **auto**: S3 [bucket lookup type](https://min.io/docs/minio/linux/developers/go/API.html#constructor).
- `auto` Auto detected
- `dns` Virtual Host style
- `path` Path Style
- `MINIO_LOCATION`: **us-east-1**: S3 location to create bucket.
- `MINIO_USE_SSL`: **false**: S3 enabled ssl.
- `MINIO_INSECURE_SKIP_VERIFY`: **false**: S3 skip SSL verification.
- `MINIO_CHECKSUM_ALGORITHM`: Minio checksum algorithm: **default** (for MinIO, garage or AWS S3) or **md5** (for Cloudflare or Backblaze)
When used in the `[storage]` section they apply to all
subsystems. When used in the section specific to a subsystem (see the table in the introduction), they
are only used for objects that belong to this subsystem. Here is a example:
```
[storage]
STORAGE_TYPE = minio
SERVE_DIRECT = false
MINIO_ENDPOINT = garage:9000
MINIO_ACCESS_KEY_ID = [redacted]
MINIO_SECRET_ACCESS_KEY = [redacted]
MINIO_BUCKET = forgejo
MINIO_BUCKET_LOOKUP = auto
MINIO_LOCATION = us-east-1
MINIO_USE_SSL = false
MINIO_INSECURE_SKIP_VERIFY = false
MINIO_CHECKSUM_ALGORITHM = md5
[lfs]
STORAGE_TYPE = minio
MINIO_BASE_PATH = nonstandardlfs/
SERVE_DIRECT = false
MINIO_ENDPOINT = minio:9000
MINIO_ACCESS_KEY_ID = [redacted]
MINIO_SECRET_ACCESS_KEY = [redacted]
MINIO_BUCKET = forgejo
MINIO_BUCKET_LOOKUP = auto
MINIO_LOCATION = us-east-1
MINIO_USE_SSL = false
MINIO_INSECURE_SKIP_VERIFY = false
```
- `MINIO_BASE_PATH`: **only valid in the specific subsystem section (see the table in the introduction)**
overrides the default directory in which objects are stored in the `MINIO_BUCKET` bucket.
For all subsystems that use the `minio` storage type found in the
`[storage]` section, the directory in which the objects are stored is
determined using the table in the introduction. For instance LFS files will be
stored in the `lfs/` directory within the `forgejo` bucket.
When the `minio` storage is set in a section specific to a subsystem,
the `MINIO_BASE_PATH` setting can be used to override the default
directory. In the example above, `MINIO_BASE_PATH = nonstandardlfs/`
means LFS objects will be stored in the `nonstandardlfs/` directory
within the `forgejo` bucket instead of the `lfs/` directory
## S3 servers compatibility
Although the S3 storage type is named `minio` it does not rely on any
[MinIO](https://min.io/) specific features. The S3 storage type is
[tested](https://code.forgejo.org/forgejo/end-to-end/src/commit/9cfd043b8af18ce0df48fa6e44772d9bd521cab4/storage/storage.sh) to be compatible with:
- [MinIO](https://min.io/) 2021.3.17 and 2023-08-23
- [garage](https://garagehq.deuxfleurs.fr/) v0.8.2
## Undocumented features
It is **strongly** recommended to avoid using undocumented features -
such as `[storage.attachments]` as an alternative to `[attachment]`
for instance (the plural is not a typo, it is a unification problem) -
because their behavior is not thoroughly tested and may lead to
unexpected results.
There are no safeguards preventing the use of undocumented features
because it may not be backward compatible when upgrading from Gitea to
Forgejo.
## Legacy settings
Some settings are deprecated but still supported in the interest of
backward compatibility. They should be replaced as follows:
- `[server].LFS_CONTENT_PATH` is replaced with `[lfs].PATH`
- `[picture].AVATAR_UPLOAD_PATH` is replaced with `[avatar].PATH`
- `[picture].REPOSITORY_AVATAR_UPLOAD_PATH` is replaced with `[repo-avatar].PATH`
Legacy settings have a lower priority and will be overridden by their
replacement if both are present. For instance:
```
[picture]
AVATAR_UPLOAD_PATH = /legacy_path
[avatar]
PATH = /avatar_path
```
will store avatar files in `/avatar_path`.
