# Minio GCS Gateway [](https://slack.minio.io)
|
|
Minio GCS Gateway adds Amazon S3 compatibility to Google Cloud Storage.
|
|
|
|
## Run Minio Gateway for GCS
|
|
### Create service account key for GCS and get the credentials file
|
|
1. Go to the [API Console Credentials page](https://console.developers.google.com/project/_/apis/credentials).
|
|
2. Select your project or create a new project. Note down your project ID.
|
|
3. On the Credentials page, select the __Create credentials__ drop-down, then select __Service account key__.
|
|
4. From the __Service account__ drop-down, select __New service account__
|
|
5. Fill up __Service account name__ and __Service account ID__
|
|
6. For the __Role__, click the selec dropdown to choose __Storage__ -> __Storage Admin__ _(Full control of GCS resources)_
|
|
7. Click the __Create__ button. This will download a credentials file to your desktop. Let's call this credentials.json
|
|
|
|
Note: Alternate ways to setup *Application Default Credentials* is explained [here](https://developers.google.com/identity/protocols/application-default-credentials)
|
|
|
|
### Using Docker
|
|
```
|
|
docker run -p 9000:9000 --name gcs-s3 \
|
|
-v /path/to/credentials.json:/credentials.json \
|
|
-e "GOOGLE_APPLICATION_CREDENTIALS=/credentials.json" \
|
|
-e "MINIO_ACCESS_KEY=minioaccountname" \
|
|
-e "MINIO_SECRET_KEY=minioaccountkey" \
|
|
minio/minio gateway gcs yourprojectid
|
|
```
|
|
|
|
### Using Binary
|
|
```
|
|
export GOOGLE_APPLICATION_CREDENTIALS=/path/to/credentials.json
|
|
export MINIO_ACCESS_KEY=minioaccesskey
|
|
export MINIO_SECRET_KEY=miniosecretkey
|
|
minio gateway gcs yourprojectid
|
|
```
|
|
|
|
## 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 mygcs http://gateway-ip:9000 minioaccesskey miniosecretkey
|
|
```
|
|
|
|
### List containers on GCS
|
|
```
|
|
mc ls mygcs

|
|
[2017-02-26 22:10:11 PST] 0B test-container1/
|
|
```
|
|
|
|
### Known limitations
|
|
|
|
Gateway inherits the following GCS limitations:
|
|
|
|
- Maximum number of multipart parts per upload is 1024.
|
|
- Only read-only or write-only bucket policy supported at bucket level, all other variations will return API Notimplemented error.
|
|
- _List Multipart Uploads_ and _List Object parts_ always returns empty list. i.e Client will need to remember all the parts that it has uploaded and use it for _Complete Multipart Upload_
|
|
|
|
Other limitations:
|
|
|
|
- Bucket notification APIs are not supported.
