Create a stack

Last Updated: May 18, 2018

Call /stacks by POST to create stacks.


  • A stack is created based on your designated template and parameters.
  • The template content is submitted along with the HTTP message body.
  • You must specify the stack name. After the stack is created successfully, the Resource Orchestration Service (ROS) returns an ID that uniquely identifies the stack in subsequent actions.
  • The stack is created in the namespace corresponding to your user ID. Therefore, the stacks created with the same user ID in the same region must have a unique name.
  • The stack cannot be renamed once created.
  • The stack ownership is non-transferable.
  • The region where the stack is created must be specified in the format of x-acs-region-id.
  • All resources under the stack must be located in the same region as the stack.
