secret命令 创建Secret） 假设Pod需要访问数据库。Pod所使⽤的⽤户名和密码在本地机器上的 ./username.txt 和 ./password.txt ⽂件中。 # Create files needed for rest of example. $ echo -n "admin" > ./username.txt $ echo -n "1f2d1e2e67df" > ./password 供Pod中的容器使⽤。 它们也可被系统的其他部分使⽤， ⽽不会直接暴露在Pod内。例如，它们可保存系统其他部分应该使⽤的凭据，从⽽代表你外部系统进⾏交互。 Using Secrets as Files from a Pod（使⽤Secret作为来⾃Pod的⽂件） 在Pod中的volume中使⽤Secret： 1. 创建⼀个secret或使⽤现有的secret。多个Pod可引⽤相同的secret。 中指定的key。如果要投影Secret中的所有key，那么所有 key都必须列在 items 字段中。 所有列出的key必须存在于相应的Secret中。否则，Volume不会被创建。 Secret files permissions （Secret⽂件权限） 你也可以指定⼀个Secret的权限模式位。如不指定，默认使⽤ 0644 。可指定整个Secret Volume的默认模式，并根据 需要覆盖每个key。
