AngularJS - move repeating functions from controller to service

Asked 2021-Jul-28 at 16:14

Hi I'm pretty new at angular JS and i'm trying to refactor my controller and want to move repeating multisort function as a service and call it back in the controller.

Can someone help me in converting this below function as a service as it has all $scope and I know it can't be used in the service or factory:

If you dont want to change the code, you can directly pass $scope to the service and get as scope.

Below is an working example, simplified on your requirement.

QUESTION

Start container instance on web request to FQDN

Asked 2020-Dec-17 at 23:09

Let's say we have a (containerized) backend which is only sparely used. Maybe once every couple of days or so, a (static) web front-end calls an API endpoint of that backend.

The backend conveniently happens to be stateless. No data store or anything.

We want to minimize the hosting cost for it, and ideally would like per-second billing. It's only gonna be running for a few minutes every month, and we only want to be charged for that usage. Basically, we want Function as a Service (FaaS), but for a whole backend and not just a single function.

Azure Container Instances appears to be great fit for this scenario. It can spin up the backend in a container when needed. The backend then can shut itself down again after a certain period of non-usage.

So, let's create a container instance...

Azure Container Instances don't have a wehbook or HTTP trigger that will start them. However, you could use an Azure Function or Logic App that would effectively run az container start for you and then call THAT with HTTP. With either of those approaches, you'd have to setup some IAM permissions to give the Function or Logic App permissions to the ACI resource to start it.

One approach would be to:

Create an Azure Function with an HTTP trigger and a managed identity
Give the Managed identity contributor access to ACI container group
Run az container start or the equivalent REST call inside the function to start the ACI container
Call the Azure function (using the function token) to start the container.

Install faas-tutorial

Local development and testing can be done using minishift. Minishift is a tool that helps you run OpenShift locally by running a single-node OpenShift cluster inside a VM. Details on minishift and installation procedures can be found here.
Some images that are in Apache OpenWhisk Docker hub requires anyuid SCC in OpenShift
This is needed for pods to communicate with each other within the cluster (TODO: need to add more clear details here)
The project OpenWhisk on OpenShift provides the OpenShift templates required to deploy Apache OpenWhisk.
Its always better to group certain class of applications, create a new OpenShift project called faas to deploy all OpenWhisk applications
Make sure we are in right project
Deploy OpenWhisk applications to openwhisk project
(Optional) Add developer user as admin to faas project so as to allow you to login with developer user and access faas project
Clone the complete project from git clone https://github.com/redhat-developer-demos/faas-java-tutorial, we will refer to this location as $PROJECT_HOME through out the document for convenience.
Maven Archetype can be used to generate the template Java Action project, as of writing this tutorial the archetype is not maven central hence it need to install it locally,.
