Installation



Way 1 (Recommended):


    Use this ready to use docker image.

          

    docker pull 2017003525/blockchain-development

    docker run -it --name ethereum_todo_list -p 8576:8545 -p 80:3000 -p 81:3001 2017003525/blockchain-development



To open more terminals for this container run,



    docker exec -it ethereum_todo_list bash



Way 2: (Longer method, create docker image from scratch): 



    docker run -it ubuntu

    docker run -it --name ethereum_todo_list -p 8576:8545 -p 80:3000 -p 81:3001 ubuntu



on your container execute below:



    apt-get update && apt-get upgrade 

    apt-get install sudo build-essential python3 wget curl

    

Then install nvm from https://github.com/nvm-sh/nvm#install--update-script



On above link there must be these two commands but with updated versions 



    curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash

    wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash



then install node and npm with:



    nvm install node

    node install npm

    npm install npm

 

after executing 



    nvm install-latest-npm



you'll find a statement to update npm to the latest version, execute that command, which should look like, `npm install -g [email protected]`, after that install truffle



    npm install -g truffle



there will be a permission issue in executing above command for which you've to execute 



    sudo chown -R $(whoami) 



**Note:** the above command has path to `node_modules` you need to find the path to your node_modules from your error. in my case it was `/root/.nvm/versions/node/v17.9.0/lib/node_modules/` so i executed, `sudo chown -R $(whoami) /root/.nvm/versions/node/v17.9.0/lib/node_modules/`



retry `npm install -g truffle`



after this you should be done with installation, but you would face problems where you couldn't execute the truffle file. 

for this just allow your truffle file to be executed by running: 

`chmod u+x ` you may find the path to truffle with which truffle, execute as below.



`chmod u+x /root/.nvm/versions/node/v17.9.0/bin/truffle`



For Ganache installation:



    npm install ganache --global



To your package.json add, 



    "scripts": {

      "ganache": "ganache --wallet.seed myCustomSeed"

    }

   



Execution



Execute Ganache, this will start your personal blockchain network on your local device.

 

    npm run ganache -h 0.0.0.0



you should be able to see output something like `RPC Listening on 0.0.0.0:8545`



now execute truffle console, make sure you add correct port number like above `8545` in file `truffle-config.js` of your code, when you use it.

 

Now for development and deployment of your own smart contracts, execute in your project directory ie.  

    

    truffle console



Again in in your project directory ie. , execute



    npm run dev



Now you should be able to access the todolist UI with browser on your host OS with 

    

    http://localhost/



Now you need to configure metamask extension to be able to access your blockchain through your browser.
