Demo Operation

Build and Run

Enter the working folder and set the variables with the corresponding IP addresses of each machine in the scripts
```
cd ./src/
```

Build and run the blockchain service from a docker container

docker build -f ./blockchain/Dockerfile_BLOCKCHAIN --no-cache --progress=plain -t pti_blockchain . | more
docker run --name pti_blockchain -d -p 8545:8545 pti_blockchain

Install Truffle suite
```
npm install -g truffle
```
View the deployed contracts addresses (not necessary to compilate ‘abis’ again)
```
truffle networks 
```

Build and run the database from a docker container

docker build -f ./database/Dockerfile_DATABASE --no-cache --progress=plain -t pti_database . | more
docker run --name pti_database -d -p 27017:27017 pti_database

Fill the database with the initial content (blockchain accounts and default username and password)
```
python3 ./database/init_database_accounts.py
python3 ./database/init_database_users.py
```

Build and run the webserver (backend) from a docker container

docker build -f ./webserver/Dockerfile_WEBSERVER --no-cache --progress=plain -t pti_webserver . | more
docker run --name pti_webserver -d -p 80:80 pti_webserver

Build and run the frontend app from a docker container (If necessary change the running port in the command, Dockerfile and server_app.py script)

docker build -f ./frontend/Dockerfile_FRONTEND --no-cache --progress=plain -t pti_frontend . | more
docker run --name pti_frontend -d -p 80:80 pti_frontend

View the 10 accounts (and private keys) configured in the blockchain and the database (View the file)
```
cat ./blockchain/ganache_accounts.json
```
Import account to Metamask extension using the account private key
Import the four working Tokens to the Metamask account using the compiled contract addresses (View the file)
Finally… explore the application!

Useful commands

Migrate contracts to the blockchain (from the ‘./src/blockchain/’ directory where the ‘truffle-config.js’ file is located)

truffle networks --clean
truffle migrate --reset

Enter Docker container interactively

docker run -it --entrypoint bash <containerName>

Stop and Remove Docker container

docker stop <containerName>
docker rm <containerName>

Check Docker logs

docker logs <containerName>

Copy from Docker container to host

docker cp <containerId>:/file/path/within/container /host/path/target

Add SSH Key to the ssh-agent

eval $(ssh-agent -s)
ssh-add ~/.ssh/id_rsa_pti_server

Fetch a single file from Github

git fetch && git checkout origin/master -- ./src/blockchain/Dockerfile_BLOCKCHAIN

Build a docker container that will fetch from github using ssh

docker build -f ./webserver/Dockerfile_WEBSERVER --no-cache --progress=plain --secret id=id_rsa_pti_server,src=/home/jquintana/.ssh/id_rsa_pti_server -t pti_webserver . | more
