## S3
### Using Minio SDK
First install the SDK:
```bash
pip3 install minio
```
Then instantiate a client object using garage root domain, api key and secret:
```python
import minio
client = minio.Minio(
"your.domain.tld",
"GKyourapikey",
"abcd[...]1234",
# Force the region, this is specific to garage
region="region",
)
```
Then use all the standard S3 endpoints as implemented by the Minio SDK:
```
# List buckets
print(client.list_buckets())
# Put an object containing 'content' to /path in bucket named 'bucket':
content = b"content"
client.put_object(
"bucket",
"path",
io.BytesIO(content),
len(content),
)
# Read the object back and check contents
data = client.get_object("bucket", "path").read()
assert data == content
```
For further documentation, see the Minio SDK

In return, this system is a bit harder to configure.
We show how it is still possible to configure Garage with Peertube, allowing you to spread the load and the bandwidth usage on the Garage cluster.
Starting from version 5.0, Peertube also supports improving the security for private videos by not exposing them directly
but relying on a single control point in the Peertube instance. This is based on S3 per-object and prefix ACL, which are not currently supported
in Garage, so this feature is unsupported. While this technically impedes security for private videos, it is not a blocking issue and could be
a reasonable trade-off for some instances.
