Angular: Render component from variable

In my component, I have a list of components that I received via @ContentChildren. Now I want to render these components in my view, but I am stuck with how to do so. I experimented with ng-container and ng-content, but I had no success with them. I was thinking of something along the lines:

<component-renderer [component]="myComponent"></component-renderer>

But I have not found anything that offers this functionality. I put together a full (as minimal as I could) example to get the picture (maybe I already went wrong some step before?). It is also important that I get the reference to those components in my component, as they will all implement a specific interface that I want to use:

MyInterface.ts

import { InjectionToken } from "@angular/core";

export const MyInterfaceToken = new InjectionToken<MyInterface>('MyInterfaceToken');

// This interface will be implemented by the "child" components.
export interface MyInterface {
    doSomething(): void;
}

simple.component.ts

import { Component, OnInit, Input, forwardRef } from '@angular/core';
import { MyInterface, MyInterfaceToken } from '../MyInterface';

@Component({
  selector: 'app-simple',
  template: '<div>{{ value }}</div>',
  providers: [{
    provide: MyInterfaceToken, useExisting: SimpleComponent
  }]
})
export class SimpleComponent implements MyInterface {
  @Input() public value: string;

  doSomething(): void {
    alert(this.value);
  }
}

multi-container.component.ts

import { Component, OnInit, Self, Inject, Optional, Directive, ContentChildren, AfterContentInit, QueryList } from '@angular/core';
import { MyInterface, MyInterfaceToken } from '../MyInterface';

// Directive to retreive the components, partially taken from:
// https://github.com/angular/angular/issues/8277
@Directive({ selector: '[multi-container-item]' })
export class MultiContainerItemDirective {
  constructor(@Inject(MyInterfaceToken) @Self() @Optional() public component: MyInterface) {}
}

@Component({
  selector: 'app-multi-container',
  templateUrl: './multi-container.component.html'
})
export class MultiContainerComponent implements AfterContentInit {
  @ContentChildren(MultiContainerItemDirective) public items: QueryList<MultiContainerItemDirective>;

  public ngAfterContentInit() {
    console.log(this.items); // Inspect in console => got both items.
    this.items.first.component.doSomething(); // works.
  }

  public getComponents() {
    return this.items.map(x => x.component);
  }
}

usage example

<app-multi-container>
  <app-simple [value]="'Test1'" multi-container-item></app-simple>
  <app-simple [value]="'Test2'" multi-container-item></app-simple>
</app-multi-container>

To put the question short: What do I put into the html of multi-container to render the items? Something like:

<div *ngFor="let component of getComponents()">
  <component-renderer [component]="component"></component-renderer>
</div>
