1. A computer-implemented method for verifying a resource definition, comprising:
simulating an original resource definition, defined for a container manager, using a DryRun function of the container manager to generate a simulated resource definition according a change that is made to the original resource definition by the container manager;
identifying the change using a comparison of the original resource to the simulated resource definition;
generating a signature of a received resource definition, omitting portions of the received resource definition that correspond to the at least one identified change;
comparing the signature of the received resource definition to a signature of the original resource definition to find a match and to verify the received resource definition; and
implementing the received resource definition, responsive to finding the match.
