Package resmgmt enables creation and update of resources on a Fabric network. It allows administrators to create and/or update channnels, and for peers to join channels. Administrators can also perform chaincode related operations on a peer, such as installing, instantiating, and upgrading chaincode. 

Basic Flow:
1) Prepare client context
2) Create resource managememt client
3) Create new channel
4) Peer(s) join channel
5) Install chaincode onto peer(s) filesystem
6) Instantiate chaincode on channel
7) Query peer for channels, installed/instantiated chaincodes etc.
Example 
// Create new resource management client
c, err := New(mockClientProvider())
if err != nil {
	fmt.Println("failed to create client")
}

// Read channel configuration tx
channelConfigTxPath := filepath.Join(metadata.GetProjectPath(), metadata.ChannelConfigPath, channelConfigTxFile)
r, err := os.Open(channelConfigTxPath)
if err != nil {
	fmt.Printf("failed to open channel config: %s\n", err)
}
defer r.Close()

// Create new channel 'mychannel'
_, err = c.SaveChannel(SaveChannelRequest{ChannelID: "mychannel", ChannelConfig: r})
if err != nil {
	fmt.Printf("failed to save channel: %s\n", err)
}

peer := mockPeer()

// Peer joins channel 'mychannel'
err = c.JoinChannel("mychannel", WithTargets(peer))
if err != nil {
	fmt.Printf("failed to join channel: %s\n", err)
}

// Install example chaincode to peer
installReq := InstallCCRequest{Name: "ExampleCC", Version: "v0", Path: "path", Package: &resource.CCPackage{Type: 1, Code: []byte("bytes")}}
_, err = c.InstallCC(installReq, WithTargets(peer))
if err != nil {
	fmt.Printf("failed to install chaincode: %s\n", err)
}

// Instantiate example chaincode on channel 'mychannel'
ccPolicy := policydsl.SignedByMspMember("Org1MSP")
instantiateReq := InstantiateCCRequest{Name: "ExampleCC", Version: "v0", Path: "path", Policy: ccPolicy}
_, err = c.InstantiateCC("mychannel", instantiateReq, WithTargets(peer))
if err != nil {
	fmt.Printf("failed to install chaincode: %s\n", err)
}

fmt.Println("Network setup completed")

Output:

Functions

func CalculateConfigUpdate 

func CalculateConfigUpdate(channelID string, currentConfig, newConfig *common.Config) (*common.ConfigUpdate, error)

	Version string
}

CCReference contains the name and version of an instantiated chaincode that references the installed chaincode package.

type Client 

type Client struct {
	// contains filtered or unexported fields
}

Client enables managing resources in Fabric network.

func New 

func New(ctxProvider context.ClientProvider, opts ...ClientOption) (*Client, error)
