无法使用cloudshell创建Amazon Managed Blockchain教程中的Hyperledger Fabric Client

【以下的问题经过翻译处理】 亲爱的社区，

很抱歉，我不是技术专家，我急需帮助解决使用CloudShell CLI在第四步遇到的问题 --> https://docs.aws.amazon.com/managed-blockchain/latest/hyperledger-fabric-dev/get-started-create-client.html

以下是遇到的问题：

sudo service docker start 
sudo: service: command not found 
[cloudshell-user@ip-10-4-189-71 ~]$ sudo docker version Client: 
Version: 20.10.23 
API version: 1.41 
Go version: go1.18.9 
Git commit: 7155243 
Built: Tue Apr 11 22:56:36 2023 
OS/Arch: linux/amd64 
Context: default 
Experimental: true 
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

[cloudshell-user@ip-10-4-189-71 ~]$ sudo usermod -a -G docker ec2-44-203-175-15.compute-1.amazonaws.com usermod: user 'ec2-44-203-175-15.compute-1.amazonaws.com' does not exist

$ aws managedblockchain get-member n-J5V2Q5GB2JFDPFLTWAI7DLIBCM,m-37P3WWYDBREKHNB4YRCFH2KLS4.managedblockchain.us-east-1.amazonaws.com:30002

usage: aws [options] <command> <subcommand> [<subcommand> ...] [parameters] To see help text, you can run:

aws help aws <command> help aws <command> <subcommand> help

aws: error: the following arguments are required: --network-id, --member-id
