# Minio B2 Gateway [](https://slack.minio.io) |
||||
Minio Gateway adds Amazon S3 compatibility to Backblaze B2 Cloud Storage. |
||||
|
||||
## Run Minio Gateway for Backblaze B2 Cloud Storage |
||||
Please follow this [guide](https://www.backblaze.com/b2/docs/quick_account.html) to create an account on backblaze.com to obtain your access credentials for B2 Cloud storage. |
||||
|
||||
### Using Docker |
||||
``` |
||||
docker run -p 9000:9000 --name b2-s3 \ |
||||
-e "MINIO_ACCESS_KEY=b2_account_id" \ |
||||
-e "MINIO_SECRET_KEY=b2_application_key" \ |
||||
minio/minio gateway b2 |
||||
``` |
||||
|
||||
### Using Binary |
||||
``` |
||||
export MINIO_ACCESS_KEY=b2_account_id |
||||
export MINIO_SECRET_KEY=b2_application_key |
||||
minio gateway b2 |
||||
``` |
||||
|
||||
## 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 config host add myb2 http://gateway-ip:9000 b2_account_id b2_application_key |
||||
``` |
||||
|
||||
### List buckets on Backblaze B2 |
||||
``` |
||||
mc ls myb2 |
||||
[2017-02-22 01:50:43 PST] 0B ferenginar/ |
||||
[2017-02-26 21:43:51 PST] 0B my-bucket/ |
||||
[2017-02-26 22:10:11 PST] 0B test-bucket1/ |
||||
``` |
||||
|
||||
### Known limitations |
||||
Gateway inherits the following B2 limitations: |
||||
|
||||
- No support for CopyObject S3 API (There are no equivalent APIs available on Backblaze B2). |
||||
- No support for CopyObjectPart S3 API (There are no equivalent APIs available on Backblaze B2). |
||||
- Only read-only bucket policy supported at bucket level, all other variations will return API Notimplemented error. |
||||
- DeleteObject() might not delete the object right away on Backblaze B2, so you might see the object immediately after a Delete request. |
||||
|
||||
Other limitations: |
||||
|
||||
- Bucket notification APIs are not supported. |
||||
|
||||
