## <a name="run-minio-gateway-for-gcs"></a>1. Run MinIO Gateway for GCS
|
|
|
|
### 1.1 Create a Service Account key for GCS and get the Credentials File
|
|
1. Navigate to the [API Console Credentials page](https://console.developers.google.com/project/_/apis/credentials).
|
|
2. Select a project or create a new project. Note the project ID.
|
|
3. Select the **Create credentials** dropdown on the **Credentials** page, and click **Service account key**.
|
|
4. Select **New service account** from the **Service account** dropdown.
|
|
5. Populate the **Service account name** and **Service account ID**.
|
|
6. Click the dropdown for the **Role** and choose **Storage** > **Storage Admin** *(Full control of GCS resources)*.
|
|
7. Click the **Create** button to download a credentials file and rename it to `credentials.json`.
|
|
|
|
**Note:** For alternate ways to set up *Application Default Credentials*, see [Setting Up Authentication for Server to Server Production Applications](https://developers.google.com/identity/protocols/application-default-credentials).
|
|
|
|
### 1.2 Run MinIO GCS Gateway Using Docker
|
|
```sh
|
|
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
|
|
```
|
|
|
|
### 1.3 Run MinIO GCS Gateway Using the MinIO Binary
|
|
|
|
```sh
|
|
export GOOGLE_APPLICATION_CREDENTIALS=/path/to/credentials.json
|
|
export MINIO_ACCESS_KEY=minioaccesskey
|
|
export MINIO_SECRET_KEY=miniosecretkey
|
|
minio gateway gcs yourprojectid
|
|
```
|
|
|
|
## <a name="test-using-minio-browser"></a>2. Test Using MinIO Browser
|
|
|
|
MinIO Gateway comes with an embedded web-based object browser that outputs content to http://127.0.0.1:9000. To test that MinIO Gateway is running, open a web browser, navigate to http://127.0.0.1:9000, and ensure that the object browser is displayed.
|
|
|
|
|
|
|
|
## <a name="test-using-minio-client"></a>3. Test Using MinIO Client
|
|
|
|
MinIO Client is a command-line tool called `mc` that provides UNIX-like commands for interacting with the server (e.g. ls, cat, cp, mirror, diff, find, etc.). `mc` supports file systems and Amazon S3-compatible cloud storage services (AWS Signature v2 and v4).
|
|
|
|
### 3.1 Configure the Gateway using MinIO Client
|
|
|
|
Use the following command to configure the gateway:
|
|
|
|
```sh
|
|
mc config host add mygcs http://gateway-ip:9000 minioaccesskey miniosecretkey
|
|
```
|
|
|
|
### 3.2 List Containers on GCS
|
|
|
|
Use the following command to list the containers on GCS:
|
|
|
|
```sh
|
|
mc ls mygcs
|
|
```
|
|
|
|
A response similar to this one should be displayed:
|
|
|
|
```

|
|
```
|
|
|
|
### 3.3 Known limitations
|
|
MinIO Gateway has the following limitations when used with GCS:
|
|
|
|
* It only supports read-only and write-only bucket policies at the bucket level; all other variations will return `API Not implemented`.
|
|
* The `List Multipart Uploads` and `List Object parts` commands always return empty lists. Therefore, the client must store all of the parts that it has uploaded and use that information when invoking the `_Complete Multipart Upload` command.
|
|
|
|
Other limitations:
|
|
|
|
* Bucket notification APIs are not supported.
