移动Azure资源并使用ARM模板更新它们

Question

移动资源很容易，但是使用'uniqueString（resourceGroup（）。id）'的ARM模板是否仍会更新移动的资源或创建新的资源？

Answer 1

It will create new resources. From the documentation on uniquestring it creates a deterministic unique hash from the parameters. You're feeding the resourceGroup id to create the hash. If that resource group id changes, so will the hash.

If you're appending a value to create uniqueness - a simple way is to change the template to refer to a variable called suffix, and directly assign the previously created unique id to the suffic variable.

If you wanted to create a portable, reusable template that would allow you to move resources between groups, then you'll need a different value to seed your deterministic hash, and not something that's likely to change. I use subscription().id frequently.

Another thing to look at is the template function documentation which allows you to define your own functions. You can encapsulate the unique naming logic in there also.

Probably not the answer you wanted to here though.
