 # MinioK8sBuckets
+[![Build Status](https://drone.communiquons.org/api/badges/pierre/MinioK8sBuckets/status.svg)](https://drone.communiquons.org/pierre/MinioK8sBuckets)
 
 Automatically create Minio buckets based on K8S Custom Resources.
 
-## Installation
-1. Run the following commands:
-```bash
-kubectl apply -f https://raw.githubusercontent.com/pierre42100/MinioK8sBuckets/master/yaml/crd.yaml
-kubectl apply -f https://raw.githubusercontent.com/pierre42100/MinioK8sBuckets/master/yaml/deployment.yaml
-```
-
-2. Deploy Minio
-3. Create a MinioInstance & a MinioBucket (like in [our test](test/test-inside-cluster.yaml))
-4. That's it!
-
-
-## Development
-Apply all K8s config files manually:
-
-```bash
-cat yaml/*.yaml | kubectl apply -f -
-```
-
-Note : [mc tool](https://min.io/download) is required

+# Minio K8S bucket
+
+An operator to automatically create and update S3 buckets on Minio, with their accounts.
+
+One deployed, this tool will allow you to automatically create Minio accounts associated with buckets.
+
+
+## Pre-requisites
+You will need:
+
+* `kubectl` access to the target cluster
+* A running Minio instance, and especially:
+  * The URL where the API of the instance can be reached
+  * The root credentials
+
+
+## Installation
+The operator can be installed using the following commands:
+
+```bash
+kubectl apply -f https://raw.githubusercontent.com/pierre42100/MinioK8sBuckets/master/yaml/crd.yaml
+kubectl apply -f https://raw.githubusercontent.com/pierre42100/MinioK8sBuckets/master/yaml/deployment.yaml
+```
+
+!!! warning "Known limitation"
+  The operator install a deployment on the `default` namespace. Currently, only this namespace is supported!
+
+## Configure instance
+In order to create buckets, the operator needs to know how to reach the Minio instance.
+
+You first need to secret similar to that one:
+
+```yaml
+apiVersion: v1
+kind: Secret
+metadata:
+  name: minio-root
+type: Opaque
+dyringData:
+  accessKey: <MINIO_ROOT_ACCESS_KEY>
+  secretKey: <MINIO_ROOT_SECRET_KEY>
+```
+
+Replace `<MINIO_ROOT_ACCESS_KEY>` and `<MINIO_ROOT_SECRET_KEY>` with the appropriate values.
+
+
+
+You can then declare a Minio instance simiarl to that one:
+
+```yaml
+apiVersion: "communiquons.org/v1"
+kind: MinioInstance
+metadata:
+  name: my-minio-instance
+spec:
+  endpoint: https://minio.example.com/
+  credentials: minio-root
+```
+
+!!! note
+  Minio itself can be located outside of the Kubernetes cluster.
+
+
+## Create a bucket
+You are not ready to create your first bucket!
+
+Here is a basic bucket example:
+
+```yaml
+apiVersion: "communiquons.org/v1"
+kind: MinioBucket
+metadata:
+  name: first-bucket
+spec:
+  # The name of the minio instance
+  instance: my-minio-instance
+  # The name of the bucket to create
+  name: first-bucket
+  # The name of the secret that will be created
+  # by the operator which contains credentials to 
+  # use to access the bucket
+  secret: first-bucket-secret
+```
+
+## More complete example
+Here is a more complete example that makes use of all the available options:
+
+```yaml
+apiVersion: "communiquons.org/v1"
+kind: MinioBucket
+metadata:
+  name: my-bucket
+spec:
+  instance: my-minio-instance
+  name: my-bucket
+  secret: my-bucket-secret
+  # This must be set to true to allow unauthenticated
+  # access to the bucket resources. Use this to host a
+  # static website for example
+  anonymous_read_access: true
+  # Enable versioning on the bucket => keep old versions
+  # of uploaded files
+  versioning: true
+  # If specified, a quota will be applied to the bucket, in bytes
+  quota: 1000000000
+  # Prevent files from being removed from the bucket. This parameter
+  # can not be changed, once the bucket has been created
+  lock: true
+  # Data retention policy. Versioning must be enabled to allow this
+  retention:
+    # The number of days data shall be kept
+    validity: 100
+    # compliance => nobody can bypass the policy
+    # governance => users with privileges might bypass policy restrictions
+    mode: compliance
+```
