QUESTION
I'm trying to create an internal ingress for inter-cluster communication with gke. The service that I'm trying to expose is headless and points to a kafka-broker on the cluster.
However when I try to load up the ingress, it says it cannot find the service?

ANSWER
Answered 2021-Jun-11 at 11:12Setting up ingress for internal load balancing requires you to configure a proxy-only subnet on the same VPC used by your GKE cluster. This subnet will be used for the load balancers proxies. You'll also need to create a fw rule to allow traffic as well.
Have a look at the prereqs for ingress and then look here for info on how to setup the proxy-only subnet for your VPC.
QUESTION
I am still learning Pharo, but it is a bit confusing. There two classes, CarRental
and Car
, and a Test
class, CarRentalTest
.
There are fixed number of cars, the same car cannot be rented twice, I have the code, but there is a mistake.
| carRental redPanda yellowPanda blackTesla |
carRental := CarRental new.
redPanda := Car panda.
yellowPanda := Car panda.
blackTesla := Car tesla.
carRental
addCar: redPanda;
addCar: yellowPanda;
addCar: blackTesla.
self assert: carRental availableCars size equals: 3.
carRental rent: redPanda days: 5.
self assert: carRental availableCars size equals: 2.
self assert: carRental rentedCars size equals: 1
I tried to initialize the availableCars
and rentedCard
methods, but there is still an issue.
ANSWER
Answered 2019-Jan-10 at 19:38You need to keep track of rented cars, right? To do that add the ivar rented
to the CarRental
class and initialize it to an empty collection:
rented := OrderedCollection new.
(in other words, include the line above in the #initialize
method - instance side.)
Now, every time you rent a car add it to the rented
collection:
rent: aCar
rented add: aCar
and when the car is returned
return: aCar
rented remove: aCar
Also you can add the getter method which was missing so far
rentedCars
^rented
and compute the cars available for rent as
availableCars
^cars copyWithoutAll: rented
QUESTION
Coming from a Java background it would seem to me that the constant below should be defined within the class as an instance variable. However, this doesn't work and if I want to access a variable from different functions than the constant has to be defined outside of the component class. Can someone please explain this reasoning to me? Am I just missing something simple? I got this code from codeacademy.com.
import React from 'react';
import ReactDOM from 'react-dom';
const redPanda = {
src: 'https://upload.wikimedia.org/wikipedia/commons/b/b2/Endangered_Red_Panda.jpg',
alt: 'Red Panda',
width: '200px'
};
class RedPanda extends React.Component {
render() {
return (
Cute Red Panda
);
}
}
ReactDOM.render(
,
document.getElementById('app')
);
ANSWER
Answered 2018-Feb-13 at 04:21You can use something like the following:
in another class(for example App.js
) use the following code: export const redPanda = { src: 'https://upload.wikimedia.org/wikipedia/commons/b/b2/Endangered_Red_Panda.jpg', alt: 'Red Panda', width: '200px' };
in your RedPanda
component use the following: import {redPanda} from './App';
The best way is to define all of your global constants in a file and name it something like common.js
or global.js
and import from it inside other components and files.

ANSWER
Answered 2017-Jul-15 at 16:39I am sort of confused by what you want but I am guessing that you have that user review form that you want to put on a page. You have multiple ways to do that. My personal favorite is doing it in PHP but there are other ways as well.
HTML:
PHP:
include_once 'userreview.html';
jQuery:
iFrame:
Any one of these should work. If this helped please click the check mark.
QUESTION
So I'm making a basic memory game, where I'm only trying to make two of the same ID images disappear whenever they are both clicked. However, the code below does work. Kind of.. But not entirely and I don't understand why. The problem is that sometimes only one image is hidden when both get clicked. Sometimes they all get hidden and it's an empty gameboard, other times 1, 2 or 3 single images gets left on the gameboard - what is causing this? Grateful for answers!
$(document).ready(function() {
var firstClicked;
$(".pictures").click(function() {
if (this.id == firstClicked) {
alert(firstClicked + " " + this.id); /*Just to see if both images get clicked*/
$(this).hide();
$("#" + firstClicked).hide();
firstClicked = null;
} else {
firstClicked = this.id;
}
});
});
Play game!
ANSWER
Answered 2017-Feb-07 at 10:48First of all, Id
should be a unique value. If you want the same value on multiple object, you should use something like class
or attribute
.
I changed your example to use a attribute
named cardid
.
I also cleaned the code a bit and ran it multiple times. I cant reproduce any of your errors.
Hope this solved your problem
$(document).ready(function() {
var firstClicked;
$(".pictures").click(function() {
if (firstClicked == null)
{
firstClicked = $(this).data("cardid");
$(this).addClass("selectedCard");
}
else {
if ($(this).data("cardid") == firstClicked && $(this).hasClass("selectedCard") == false)
{
$(this).remove();
$("#gameboard").find("[data-cardid='" + firstClicked + "']").remove();
}
firstClicked = null;
$(".selectedCard").removeClass("selectedCard");
}
});
});
Play game!
