# Garage Admin SDK

Operate your Garage cluster programatically

## ⚠️ DISCLAIMER

**THESE SDK ARE TECHNICAL PREVIEWS**. The following limitations apply:
  - The API is not complete, some actions are possible only through the `garage` binary
  - The underlying admin API is not yet stable nor complete, it can breaks at any time
  - The generator configuration is currently tweaked, the library might break at any time due to a generator change
  - Because the API and the library are not stable, none of them are published in a package manager (npm, pypi, etc.)
  - This code has not been extensively tested, some things might not work (please report!)

To have the best experience possible, please consider:
  - Make sure that the version of the library you are using is pinned (`go.sum`, `package-lock.json`, `requirements.txt`).
  - Join our Matrix channel at `#garage:deuxfleurs.fr`, say that you are interested by this SDK, and report any friction.
  - If stability is critical, mirror this repository on your own infrastructure, regenerate the SDKs and upgrade them at your own pace.

## For SDK users

The following languages are supported:
  - [Python](#python)
  - [Javascript](#javascript)
  - [Golang](#golang)

### Python

You need at least Python 3.6, pip, and setuptools.
Because the python package is in a subfolder, the command is a bit more complicated than usual:

```bash
pip3 install --user 'git+https://git.deuxfleurs.fr/quentin/garage-admin-sdk-python'
```

Now, let imagine you have a fresh Garage instance running on localhost, with the admin API configured on port 3903 with the bearer `s3cr3t`:

```python
import garage_admin_sdk
from garage_admin_sdk.apis import *
from garage_admin_sdk.models import *

configuration = garage_admin_sdk.Configuration(
  host = "http://localhost:3903/v0",
  access_token = "s3cr3t"
)

# Init APIs
api = garage_admin_sdk.ApiClient(configuration)
nodes, layout, keys, buckets = NodesApi(api), LayoutApi(api), KeyApi(api), BucketApi(api)

# Display some info on the node
status = nodes.get_nodes()
print(f"running garage {status.garage_version}, node_id {status.node}")

# Change layout of this node
current = layout.get_layout()
layout.add_layout({
  status.node: NodeClusterInfo(
    zone = "dc1",
    capacity = 1,
    tags = [ "dev" ],
  )
})
layout.apply_layout(LayoutVersion(
  version = current.version + 1
))

# Create key, allow it to create buckets
kinfo = keys.add_key(AddKeyRequest(name="openapi"))

allow_create = UpdateKeyRequestAllow(create_bucket=True)
keys.update_key(kinfo.access_key_id, UpdateKeyRequest(allow=allow_create))

# Create a bucket, allow key, set quotas
binfo = buckets.create_bucket(CreateBucketRequest(global_alias="documentation"))
binfo = buckets.allow_bucket_key(AllowBucketKeyRequest(
  bucket_id=binfo.id,
  access_key_id=kinfo.access_key_id,
  permissions=AllowBucketKeyRequestPermissions(read=True, write=True, owner=True),
))
binfo = buckets.update_bucket(binfo.id, UpdateBucketRequest(
  quotas=UpdateBucketRequestQuotas(max_size=19029801,max_objects=1500)))

# Display key
print(f"""
cluster ready
key id is {kinfo.access_key_id}
secret key is {kinfo.secret_access_key}
bucket {binfo.global_aliases[0]} contains {binfo.objects}/{binfo.quotas.max_objects} objects
""")
```

*This example is named `short.py` in the example folder. Other python examples are also available.*

### Javascript

Install the SDK with:

```bash
npm install --save git+https://git.deuxfleurs.fr/quentin/garage-admin-sdk-js.git
```

A short example:

```javascript
const garage = require('garage_administration_api_v0garage_v0_8_0');

const api = new garage.ApiClient("http://127.0.0.1:3903/v0");
api.authentications['bearerAuth'].accessToken = "s3cr3t";

const [node, layout, key, bucket] = [
  new garage.NodesApi(api),
  new garage.LayoutApi(api),
  new garage.KeyApi(api),
  new garage.BucketApi(api),
];

node.getNodes().then((data) => {
  console.log(`nodes: ${Object.values(data.knownNodes).map(n => n.hostname)}`)
}, (error) => {
  console.error(error);
});
```

## For SDK developpers

PR are accepted for other languages as soon as good examples are provided.
Especially, we want them to be meaningful, manually written, and covering
a large range of the API. Thanks in advance :-)

### Clone this repo

```bash
git clone ...
git submodule update --init
```

### (Re)generate libraries

```bash
# Check the OpenAPI spec file
gradle validate 

# (re)build the python client
gradle buildPythonClient

# (re)build the Go client
gradle buildGoClient
