如何在不指定固定高度的情况下最好地使这个 flexbox 达到 100% 高度？

Question

我想将这 3 个 div 均匀地放在一个列中，但它们的父级 (.outer) 不会达到其他列内容的 100% 高度。我认为是因为它的父级没有设置固定的高度。

.container{
  margin-top: 60px;
}
 .container{
  border: 1px solid #000;  
}
.outer{
  border: 1px solid #000;
}

.row-center{
  height: 100%;
}

.outer{
  display: flex;
  flex-direction: column;
  justify-content: space-around;
  height: 100%;
}

.one, .two, .three{
  flex: 0 0 40px;
  border: 1px solid #000;
}

<div class="container">
  <div class="row">
    <div class="col-xs-6"><img src="http://placehold.it/350x500"></div>
    <div class="col-xs-6 row-center">
      <div class="outer">
        <div class="one">some text</div>
        <div class="two">some text</div>
        <div class="three">some text</div>
      </div>
    </div>
  </div>
</div>

这里最好的程序是什么？我尝试过绝对定位.outer，但无法正常工作。
