Practice Consul, Nomad in Production Part 2 - Setup DNS and Make Basic Jobs

Complete the 1st part before you go on SET UP CLUSTER

DEPLOY TRAEFIK

Create service Policy

cd ~ &&  echo "

Generate ssl certificates with Subject Alt Names on OSX

Open ssl.conf in a text editor.

Edit the domain(s) listed under the [alt_names] section so that they match the local domain name you want to use for your project, e.g.

DNS.1   = my-project.dev

Additional FQDNs can be added if required:

VAR

Scope essentially means where these variables are available for use. var declarations are globally scoped or function/locally scoped.

Ex1

var greeter = "hey hi";

if (1) {
    var hello = "hello";
    console.log(hello);
    console.log(greeter);

Let & const

let and const are the block scoped

A block is a chunk of code bounded by {}. A block lives in curly braces. Anything within curly braces is a block.

Ex1:

let greeter = "hey hi";

if (1) {

The “if” statement

Ex 1:

let year = prompt('In which year was the ECMAScript-2015 specification published?', '');

if (year == 2015) {
  alert( 'You guessed it right!' );
} else {
 alert( 'How can you be so wrong?' ); // any value except 2015

Style

Normal style:

result = (a !== null && a !== undefined) ? a : b;

Compact style:

result = a ?? b

The result of a ?? b is:

Function declare

function showMessage(from, text) { // parameters: from, text
  alert(from + ': ' + text);
}

showMessage('Ann', 'Hello!'); // Ann: Hello! (*)
showMessage('Ann', "What's up?"); // Ann: What's up? (**)
