How to align vertically in flex?

Question

css

There is a structure like this:

<div class="body">
  <div class="container">
    <div class="content">
      <p>текст</p>
    </div>
  </div>
</div>

.body has these styles:

display: flex;
  flex-wrap: nowrap;
  flex-direction: column;
  min-height: 100vh;
  min-width: auto;

how to vertically align the .container block to the center of the .body block, and push the .content block to the top of the .container block?
