I could not start fabric-orderer via docker . the docker-compose file

when I use it to start docker. the error code is.

failed to parse config: Error reading configuration: Unsupported Config Type ""

but when I add this line to the environment.

- FABRIC_CFG_PATH=/etc/hyperledger/org0/orderer and add a orderer.yaml to the /opt/hyperledger/org0/orderer floder, the error code is * '' has invalid keys: admin and when I remove the

Admin:
    # host and port for the admin server
    ListenAddress: 127.0.0.1:9443    # TLS configuration for the admin endpoint
    TLS:
        # TLS enabled
        Enabled: false        # Certificate is the location of the PEM encoded TLS certificate
        Certificate:        # PrivateKey points to the location of the PEM-encoded key
        PrivateKey:        # Most admin service endpoints require client authentication when TLS
        # is enabled. ClientAuthRequired requires client certificate authentication
        # at the TLS layer to access all resources.
        #
        # NOTE: When TLS is enabled, the admin endpoint requires mutual TLS. The
        # orderer will panic on startup if this value is set to false.
        ClientAuthRequired: true        # Paths to PEM encoded ca certificates to trust for client authentication
        ClientRootCAs: []

block from orderer.yaml

the error code is

panic: Failed validating bootstrap block: initializing channelconfig failed: could not create channel Consortiums sub-group config: setting up the MSP manager failed: administrators must be declared when no admin ou classification is set

so, is there a right way to start a fabric-orderer docker ?

Thanks a lot.

Solution

[YOUR SECOND ERROR]
Admin is an invalid config value.

It needs to be changed to General. Please refer to the link below
sampleconfig/orderer.yaml

[YOUR FIRST ERROR]
Try adding FABRIC_CFG_PATH parameter in docker-compose.yaml FABRIC_CFG_PATH is the directory path where the orderer.yaml file exists.

~~~
  orderer1-org0:
    container_name: orderer1-org0
    image: hyperledger/fabric-orderer:2.2.1
    environment:
      - FABRIC_CFG_PATH=/etc/hyperledger/org0/orderer/
~~~

Additionally, check the GENERAL_GENESISFILE value in orderer.yaml. When you see the configuration you have written, it should be written as below in orderer.yaml.

~~~
GenesisFile: /etc/hyperledger/orderer/orderer.genesis.block
~~~
