Hyperledger Fabric stand-alone Docker CLI startup and query transfer operation

Start Fabric

Now that all the files are ready, we can start our fabric network. Start Orderer

Let's start with the Orderer node and run on the Orderer server:

After running, we can use Docker PS to see a node running with a name of orderer.example.com.

[ROOT@IZ2ZEIVRKCKULQ2DTIDZTMZ e2e_cli]# docker-compose-f docker-compose-cli.yaml up warning:the CHANNEL_NAME variable is isn't set.
Defaulting to a blank string. Warning:the TIMEOUT variable is not set.

Solving method

1 The first: Here we will Python's default encoding to Utf-8, we can circumvent the above problem, in particular, we add the following code in the Python file:

import sys
defaultencoding = ' Utf-8 '
if sys.getdefaultencoding ()!= defaultencoding:
    reload (SYS)
    sys.setdefaultencoding ( defaultencoding) (
 2) The second: we add a sitecustomize.py file in the/usr/lib/python2.7/site-packages/directory, which reads as follows:

Import sys
sys.setdefaultencoding (' utf-8 ')
 this way can solve all the encoding problems of the project, specific instructions can refer to/usr/lib/python2.7/site.py file:

Docker-compose-f Docker-compose-cli.yaml Down

Execute command

Docker run-it CLI Bash

Abnormal:

[ROOT@IZ2ZEIVRKCKULQ2DTIDZTMZ e2e_cli]# Docker exec-it CLI bash
Error response from Daemon:container 1f9b6f7d709f26 3F4A67A67AD91B419B13844EFAAA4CAEB6DD571BFA829822C7 is not running

Workaround:

CLI:
    container_name:cli ...
   Working_dir:/opt/gopath/src/github.com/hyperledger/fabric/peer
   # command:/bin/bash-c './scripts/script.sh ${ Channel_name} ${delay}; Sleep $TIMEOUT '
    volumes:
        -/var/run/:/host/var/run/
...

Comments

Command:/bin/bash-c './scripts/script.sh ${channel_name} ${delay}; Sleep $TIMEOUT '

Enter CLI execution

./scripts/script.sh MyChannel
