typescript - How to place a dynamic component in a container

Question

I want to create dynamic components and insert views of these components to a container.

I think this can be achieved by ViewContainerRef.

But I don't know, can we get ViewContainerRef of any component? if yes then how?. I am new to Angular, if there are any other good solutions available to handle this scenario, please suggest me.

Updated I think, I am pretty much near to the solution. Below is the code.

app.component.ts

import {Component} from '@angular/core';
import {ContainerComponet} from './container.component'

@Component({
    selector: 'my-app',
    template: `
    <container> </container>
    `,
    directives: [ContainerComponet]
})
export class AppComponent {

    constructor() { }

 }

container.component.ts

import {Component, ComponentResolver, ViewContainerRef} from '@angular/core'
import {controlBoxComponent as controlBox} from './controlBox.component';

@Component({
    selector: 'container',
    template: 'container'    
})
export class ContainerComponet {
    constructor(viewContainer: ViewContainerRef, private _cr: ComponentResolver) {

        this._cr.resolveComponent(controlBox)
            .then(cmpFactory => {
                const ctxInjector = viewContainer.injector;
                return viewContainer.createComponent(cmpFactory, 0,  ctxInjector);
            })

    }
}

controlBox.component.ts

import {Component} from '@angular/core'
@Component({
    selector: 'controlBox',
    template: 'controlBox'
})
export class controlBoxComponent {
    constructor() { }
}

Output

<my-app>
    <container>container</container><controlbox _ngcontent-lsn-3="">controlBox</controlbox>
</my-app>

Expected Result

<my-app>
    <container>container
    <controlbox _ngcontent-lsn-3="">controlBox</controlbox>
    </container>
</my-app>

You can get the ViewContainerRef of the current component by or from an element in the view of the current component

@Component({
  selector: '...',
  directives: [OtherComponent, FooComponent],
  template: `
    <other-component></other-component>
    <foo-component #foo></foo-component>
    <div #div></div>`
})

export class SomeComponent {
  // `ViewContainerRef` from an element in the view
  @ViewChild(OtherComponent, {read: ViewContainerRef}) other;
  @ViewChild('foo', {read: ViewContainerRef}) foo;
  @ViewChild('div', {read: ViewContainerRef}) div;

  // `ViewContainerRef` from the component itself
  constructor(private viewContainerRef:ViewContainerRef, private componentFactoryResolver: ComponentFactoryResolver) {}

  let factory = this.componentFactoryResolver.resolveComponentFactory(ControlBox)
  this.componentRef = this.other.createComponent(factory);
  // this.componentRef = this.foo.createComponent(factory);
  // this.componentRef = this.div.createComponent(factory);
  // this.componentRef = this.viewContainerRef.createComponent(factory);
  });
}
