yorc-storage-plugin

A yorc storage sample plugin where deployments are stored in the file system

This sample shows how to create a Go plugin to externalize Yorc storage for a defined store type.

Here is implemented a file system store to save all deployments data in a specified directory.

The store plugin in few steps

• Define an exported plugin "symbol" Store

 var Store fileStore

• In the init function of main.go, instantiate the Store previously declared

• The store implementation has to implement yorc storage.Store interface (file_store.go) Note the Types() method determines which store type(s) is concerned

func (s *fileStore) Types() []types.StoreType {
	t := make([]types.StoreType, 0)
	t = append(t, types.StoreTypeDeployment)
	return t
}

• The store plugin binary must be named store_*.so to be loaded by yorc.

• If you use other standard Yorc plugins (HashiCorp RPC) for delegate/operations by example, you need to compile them with CGO_ENABLED=1 and with the reference to the Yorc local version in the go.mod file as it's done here.

How to build

• Build yorc locally with the CGO enabled (export CGO_ENABLED=1)
• Set the yotc sources path in the go.mod file (replace cmd)
• Build this plugin (make)
