選択肢
- A domain of the performance monitoring service has to be there, along with a token for a user who may reach the registry of the images and rules for a user who is not an administrator, and it can be chosen while the stack is being created, and at no later time
- A domain of the performance monitoring service has to be there and nothing besides, since the stack draws the token and the rules from the account of the owner, and it can be chosen while the stack is being created, and at no later time
- A domain of the performance monitoring service has to be there, along with a token for a user who may reach the registry of the images and rules for a user who is not an administrator, and it can be chosen at any later time, no matter how the stack was made, by running the job that applies it again
- A load balancer and a bastion have to be there, since the scaling of a stack is driven through the two of them, and it can be chosen at any later time, no matter how the stack was made, by running the job that applies it again
