我想让下图中的外框具有相同的高度：
以下是代码：

我尝试设置 domainBox 类的属性minimum height。以下是我得到的结果：
外框现在高度相同，但对齐不正确。你知道原因吗？
答案1
在第一种和第二种情况下，可以为fit节点添加一个坐标。例如，
\node [ domainBox, draw=black!50, fit={ (adminDom) (hostDaemon) (adminDom.south|-proxyGpu.south) }] (bigAdminBox) {};
这里我添加了(adminDom.south|-proxyGpu.south)，即 x 坐标为adminDom.south， y 坐标为 的坐标proxyGpu.south。
当然，proxyGpu节点必须可用，因此我将前两个fit节点移至代码末尾附近。
