Deploying the Application

This section describes how to deploy the application.

Deploying the Application

To obtain the image, go to the BCS console and choose Use Cases. Download Bank_Image in the SDK Demo for a Bank Consortium Blockchain area.

Ensure that the docker and unzip commands exist before logging in to ECS.

Run the cd /root/bankuniondemo command to upload the downloaded image to the directory.

Run the vi startserver.sh command to create the startserver.sh file. Add the following content to the startserver.sh file and save the file:

#!/bin/sh
# Obtain the current path.
path=`pwd`
# Obtain the IP address.
localip=`ifconfig eth0 | grep "inet addr" | awk '{ print $2}' | awk -F: '{print $2}'`

# Check whether unzip and docker commands exist.
if type unzip > /dev/null 2>&1; then
    echo "Unzip command is exists!"
else
    echo "No unzip command, please install unzip before start this demo"
    exit 1
fi

if type docker > /dev/null 2>&1; then
    echo "Docker exists!"
else
    echo "No docker, please install docker before start this demo"
    exit 1
fi

# Check whether the certificate directory exists.
if [ -e ./crypto ];then
rm -rf crypto
fi

# Decompress the certificate file.
echo "Start unziping certificate ...."

cerzip=$(ls|grep .zip)
for i in $cerzip;
do
unzip -n $i -d crypto/
done
echo "Unzip certificate Done!!"

# Configure the certificate path.
Folder="$path/crypto"  
for file in ${Folder}/*
do  
    temp_file=`basename $file`  

    mv -f $path/crypto/$temp_file/* $path/crypto/
done

# Check whether the required certificate files are ready.
echo "Start checking if the required files are ready"
if [ -e $path/democraticBank.yaml ]&&[ -e $path/civilizationBank.yaml ]&&[ -e $path/harmoniousBank.yaml ];then
echo "Check required yaml files OK!!"
else
echo "Please check if the required yaml files are ready!!"
exit
fi

# Restart the system if the password is forgotten.
read -p "Is this the first time you deploy the application? If yes please insert 'y', if you want to reset your password please insert 'n': " choice
echo $choice
if [ $choice = "n" ];then
docker rm $(docker stop $(docker ps -a -q --filter ancestor=bank --format="{{.ID}}"))
echo "Resetting password..."
fi

# Set the password.
read -p "Please set your password: " test
echo $test
if [ ${#test} -lt 4 -o ${#test} -gt 24 ];then echo "password length should in [4, 24].";exit;fi

#load images
if [ -e $path/bankv3.tar.gz ];then
echo "Start loading images..."
docker load -i bankv3.tar.gz
echo "Api-server images is exists,Skip load!"
fi

# Start the service.
echo "Start server ....."
docker run --env TESTPWD=$test -p 8080:8080 -d -it -v $path/crypto:/opt/bank/src/bank/conf/crypto -v $path/democraticBank.yaml:/opt/bank/src/bank/conf/democraticBank.yaml -v $path/harmoniousBank.yaml:/opt/bank/src/bank/conf/harmoniousBank.yaml -v $path/civilizationBank.yaml:/opt/bank/src/bank/conf/civilizationBank.yaml bank

RET_CODE=`echo $?`
if [ $RET_CODE -eq 0 ]; then 
     echo "Start server success!"
     echo -e "please login \033[32mhttp://EIP:8080/adminLogin \033[0mto visit Bank Management System"
     echo -e "or login \033[32mhttp://EIP:8080/userLogin \033[0mto visit Bank Customer System"
else
     echo "Failed to start server! Please check if everything ok"
fi

Run the following script:

bash startserver.sh

After you see "Is this the first time you deploy the application?", enter y for yes, or enter n if you want to change the password. Then, insert your password (123456 is used as an example in the following figure).
The command output is similar to the following:

Figure 1 Command output
Run the following command to check whether the container has started:
docker ps

If the following information is displayed, the container has started. Otherwise, check the configuration.

Adding a Security Group

If you deploy the bankuniondemo application on your own server, skip this procedure.

If you deploy the bankuniondemo application on an ECS on Huawei Cloud, create a security group and then add security group rules to enable access to port 8080 of the server. For details, see Creating a Security Group. Table 1 describes the security group rule.

**Table 1** Parameters of a security group rule
Parameter	Setting	Description
Protocol	Select TCP.	Specifies the network protocol.
Direction	Set the inbound rules.	Specifies the direction in which the security group rule takes effect. Inbound rules control external access to the ECS.
Port number range	Create a rule, and set the port to 8080.	Specifies the port range for which a rule takes effect.
Source	Select IP Address, and enter 0.0.0.0/0.	This parameter is required for inbound rules.
