[英]aws cloud formation update packages
In aws cloud formation I know you can update the stack by updating the json file and those changes will take affect but how could I just update the stacks packages for example yum update
or apt update
etc ? 在AWS云形成中,我知道您可以通过更新json文件来更新堆栈,这些更改将生效,但是我如何才能更新堆栈包,例如
yum update
或apt update
等?
