+# CDS Artifact Manager
+
+Artifact Manager is a very simple gRPC service that lets you upload, download and delete CBA archives. It can be ran as a standalone micro service (using `server.py`) or you can include it's methods in a service like `py-executor`.
+
+## Configuration
+Configuration is stored in `.ini` file, you can specify a path and name of a file using `CONFIGURATION` env variable.
+For possible variables please see example below (with inline comments):
+```
+[artifactManagerServer]
+port=50052                    # A port on which the server will be listening
+logFile=server.log            # Path to a log file
+maxWorkers=20                 # Max number of concurent workers
+debug=true                    # Debug flag
+logConfig=logging.yaml        # A special MDC logger config
+fileRepositoryBasePath=/tmp/  # A FS path where we should store CBA files
+```
+
+## Methods
+Below is a list of gRPC methods handled by the service. The `proto` files are available in `artifact-manager/manager/proto` directory.
+
+All methods expect `CommonHeader` with:
+* `timestamp` - datetime in UTC with this: `%Y-%m-%dT%H:%M:%S.%fZ` format
+* `originatorId` - name of the component (eg. `CDS`)
+* `requestId` - ID of the request
+* `subRequestId` - Sub ID of the request
+* `flag` - TBD
+
+and an `ActionIdentifiers` with following fields:
+* `blueprintName` - name of the blueprint
+* `blueprintVersion` - version number of blueprint (as string)
+* `actionName` - TBD
+* `mode` - TBD
+
+### Upload
+
+Upload `CBA.zip` file for storage in artifact manager. File needs to be sent as a binary data in `fileChunk` field.
+
+#### Example
+
+```
+stub: BluePrintManagementServiceStub = BluePrintManagementServiceStub(channel)
+with  open(file_path, "rb") as cba_file:
+    msg: BluePrintUploadInput = BluePrintUploadInput()
+    msg.actionIdentifiers.blueprintName =  "Test"
+    msg.actionIdentifiers.blueprintVersion =  "0.0.1"
+    msg.fileChunk.chunk = cba_file.read()
+return  stub.uploadBlueprint(msg)
+```
+
+### Download
+
+Download existing `CBA.zip` file.
+
+#### Example
+
+```
+stub: BluePrintManagementServiceStub = BluePrintManagementServiceStub(channel)
+msg: BluePrintDownloadInput = BluePrintDownloadInput()
+msg.actionIdentifiers.blueprintName =  "Test"
+msg.actionIdentifiers.blueprintVersion =  "0.0.1"
+return  stub.downloadBlueprint(msg)
+```
+### Remove
+
+Delete existing `CBA.zip` file.
+
+#### Example
+
+```
+stub: BluePrintManagementServiceStub = BluePrintManagementServiceStub(channel)
+msg: BluePrintRemoveInput = BluePrintRemoveInput()
+msg.actionIdentifiers.blueprintName =  "Test"
+msg.actionIdentifiers.blueprintVersion =  "0.0.1"
+return  stub.removeBlueprint(msg)
+```
