如何将两个div上下与右侧的<aside>对齐？

.container {
  display: flex;
  flex-direction: column;
}

<div class="container">
  <div>Div 1</div>
  <div>Div 2</div>
  <aside>Aside</aside>
</div>

.container div {
  align-self: flex-start;
}

.container aside {
  align-self: flex-end;
}

<style>
.container {
  display: flex;
  flex-direction: column;
}

.container div {
  align-self: flex-start;
}

.container aside {
  align-self: flex-end;
}
</style>

<div class="container">
  <div>Div 1</div>
  <div>Div 2</div>
  <aside>Aside</aside>
</div>
