sceptre: Defining an explicit dependency
1 min read
When we are using the output of one stack as a parameter for another one we are defining an implicit dependency: sceptre is going to create one first, get it's output and then create the other one. If we still need to create some stack after another but we are not using any output as parameter, we can still define an explicit dependency.
