# MinIO NAS Gateway [](https://slack.min.io)
|
|
|
|
MinIO Gateway adds Amazon S3 compatibility to NAS storage. You may run multiple minio instances on the same shared NAS volume as a distributed object gateway.
|
|
|
|
## Run MinIO Gateway for NAS Storage
|
|
|
|
### Using Docker
|
|
|
|
Please ensure to replace `/shared/nasvol` with actual mount path.
|
|
|
|
```
|
|
docker run -p 9000:9000 --name nas-s3 \
|
|
-e "MINIO_ROOT_USER=minio" \
|
|
-e "MINIO_ROOT_PASSWORD=minio123" \
|
|
-v /shared/nasvol:/container/vol \
|
|
minio/minio gateway nas /container/vol
|
|
```
|
|
|
|
### Using Binary
|
|
|
|
```
|
|
export MINIO_ROOT_USER=minio
|
|
export MINIO_ROOT_PASSWORD=minio123
|
|
minio gateway nas /shared/nasvol
|
|
```
|
|
|
|
## Test using MinIO Browser
|
|
|
|
MinIO Gateway comes with an embedded web based object browser. Point your web browser to http://127.0.0.1:9000 to ensure that your server has started successfully.
|
|
|
|
|
|
|
|
## Test using MinIO Client `mc`
|
|
|
|
`mc` provides a modern alternative to UNIX commands such as ls, cat, cp, mirror, diff etc. It supports filesystems and Amazon S3 compatible cloud storage services.
|
|
|
|
### Configure `mc`
|
|
|
|
```
|
|
mc alias set mynas http://gateway-ip:9000 access_key secret_key
|
|
```
|
|
|
|
### List buckets on nas
|
|
|
|
```
|
|
mc ls mynas
|
|

|
|
[2017-02-26 21:43:51 PST] 0B my-bucket/
|
|
[2017-02-26 22:10:11 PST] 0B test-bucket1/
|
|
```
|
|
|
|
## Breaking changes
|
|
|
|
There will be a breaking change after the release version 'RELEASE.2020-06-22T03-12-50Z'.
|
|
|
|
### The file-based config settings are deprecated in NAS
|
|
|
|
The support for admin config APIs will be removed. This will include getters and setters like `mc admin config get` and `mc admin config` and any other `mc admin config` options. The reason for this change is to avoid un-necessary reloads of the config from the disk. And to comply with the Environment variable based settings like other gateways.
|
|
|
|
### Migration guide
|
|
|
|
The users who have been using the older config approach should migrate to ENV settings by setting environment variables accordingly.
|
|
|
|
For example,
|
|
|
|
Consider the following webhook target config.
|
|
|
|
```
|
|
notify_webhook:1 endpoint=http://localhost:8080/ auth_token= queue_limit=0 queue_dir=/tmp/webhk client_cert= client_key=
|
|
```
|
|
|
|
The corresponding environment variable setting can be
|
|
|
|
```
|
|
export MINIO_NOTIFY_WEBHOOK_ENABLE_1=on
|
|
export MINIO_NOTIFY_WEBHOOK_ENDPOINT_1=http://localhost:8080/
|
|
export MINIO_NOTIFY_WEBHOOK_QUEUE_DIR_1=/tmp/webhk
|
|
```
|
|
|
|
> NOTE: Please check the docs for the corresponding ENV setting. Alternatively, We can obtain other ENVs in the form `mc admin config set alias/ <sub-sys> --env`
|
|
|
|
## Symlink support
|
|
|
|
NAS gateway implementation allows symlinks on regular files,
|
|
|
|
### Behavior
|
|
|
|
- For reads symlink resolves to file symlink points to.
|
|
- For deletes
|
|
- Delete of symlink deletes the symlink but not the real file to which the symlink points.
|
|
- Delete of actual file automatically makes symlink'ed file invisible, dangling symlinks won't be visible.
|
|
|
|
#### Caveats
|
|
- Disallows follow of directory symlinks to avoid security issues, and leaving them as is on namespace makes them very inconsistent.
|
|
- Dangling symlinks are ignored automatically.
|
|
|
|
*Directory symlinks is not and will not be supported as there are no safe ways to handle them.*
