+# Goal
+
+We want to be able to instantiate a service that allows to store file located on a `processing` pod onto it. 
+
+We have already tested it with a static `Argo` yaml file, a MinIO running on the same kubernetes node, the minio service is reached because it is the only associated to the `serviceAccount`.
+
+We have established three otpions that need to be available to the user for the feature to be implemented: 
+
+- Use a MinIO running constantly on the node that executes the argo workflow
+- Use a MinIO
+- A MinIO is instanciated when a new workflow is launched
+
+# Requirements
+
+- Helm : `https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3`
+- Helm GO client : `$ go get github.com/mittwald/go-helm-client`
+- MinIO chart : `https://charts.min.io/`
+
+
+# Ressources
+
+We need to create several ressources in order for the pods to communicate with the MinIO 
+
+## MinIO Auth Secrets
+
+## Bucket ConfigMap
+
+With the name `artifact-repositories` this configMap will be used by default. It contains the URL to the MinIO server and the key to the authentication data held in a `secret` ressource. 
+
+```yaml
+apiVersion: v1
+kind: ConfigMap
+metadata:
+  # If you want to use this config map by default, name it "artifact-repositories".
+  name: artifact-repositories
+  # annotations:
+  #   # v3.0 and after - if you want to use a specific key, put that key into this annotation.
+  #   workflows.argoproj.io/default-artifact-repository: oc-s3-artifact-repository
+data:
+  oc-s3-artifact-repository: |
+    s3:
+      bucket: oc-bucket
+      endpoint: [ retrieve cluster with kubectl get service argo-artifacts -o jsonpath="{.spec.clusterIP}" ]:9000
+      insecure: true
+      accessKeySecret: 
+        name: argo-artifact-secret
+        key: access-key
+      secretKeySecret:
+        name: argo-artifact-secret
+        key: secret-key
+
+```
+
+
+# Code modifications
+
+Rajouter un attribut "isDataLink" 
+ - true/false
+
+Rajouter un attribut DataPath ou un truc comme ca
+
+  - liste de map[string]string permet de n'avoir qu'une copie par fichier)
+  - éditable uniquement a travers la méthode addDataPath
+  - clé : path du fichier / value : nom de la copie dans minio	
+
+===> on a besoin du meme attribut pour Processing -> Data et Data -> Processing
