It´s recommended to use the truffle framework for production?? Or just to develop purpose??

I mean can I connect my truffle to my private blockchain and execute the compile/migrate commands without hesitation. Or it´s better to do this without truffle??

Yes, but...

I've found Truffle's deployment-syntax to be very cumbersome, and ended up implementing my own deployment code (though I still run it via truffle deploy or truffle migrate).

Here is an example:

let ARG1 = process.argv[4];

let ARG2 = process.argv[5];

let ARG3 = process.argv[5];



async function deploy(contractName, contractArgs = ) {

    let handle = await artifacts.require(contractName).new(...contractArgs);

    console.log(`${contractName} contract deployed at address ${handle.address}`);

    return handle;

}



async function execute() {

    let contract1 = await deploy("Contract1", [ARG1, ARG2]);

    let contract2 = await deploy("Contract2");

    let contract3 = await deploy("Contract3", [ARG3, contract1.address, contract2.address);

}



async function measure() {

    let gasPrice   = web3.eth.gasPrice;

    let bgnBalance = web3.eth.getBalance(web3.eth.accounts[0]);

    await execute();

    let endBalance = web3.eth.getBalance(web3.eth.accounts[0]);

    console.log(`Total cost: ${bgnBalance.minus(endBalance).div(gasPrice)} gas units`);

}



module.exports = function(deployer, network, accounts) {

    if (network == "production")

        deployer.then(async function() {await measure();});

};

Then calling:

truffle deploy --network=production 0x123 0x456 0x789

Of course, you'll need to add the production network in your truffle-config.js file, for example:

networks: {

    development: {

        host:       "127.0.0.1",

        port:       8545,

        network_id: "*",

        gasPrice:   0x1,

        gas:        0x1fffffffffffff

    },

    production: {

        host:       ...,

        port:       ...,

        network_id: ...,

        gasPrice:   100000000000,

        gas:        6721975

    }

}

I think at this stage of Ethereum (4 years old) and Truffle (3 years old), we can definitely recommend the Truffle suite to deploy contracts safely anywhere. It's a trusted software recognized by the entire Ethereum community.

However, it doesn't make your private key safe or anything like that. You are responsible for the security of your private keys used to deploy those contracts.
