Automated recipe generation for orchestrated application recovery

A computer usable program product comprising one or more computer readable storage media, and program instructions collectively stored on the one or more computer readable storage media, the program instructions executable by a processor to cause the processor to perform operations transferring a target application to a second container orchestrator using a snapshot of a resource state of the target application from a first container orchestrator comprising:

• executing a recipe to transfer the target application to the second container orchestrator, wherein the recipe includes an instruction to cause a change at the second container orchestrator relative to a resource involved in the transfer, the change comprising at least one of (i) changing a sequence in which the resource is restored, (ii) excluding an unrelated cluster information from a specification of the resource, (iii) changing a timing of restoration of the resource, and (iv) correcting a stale cluster information in the specification of the resource;
• re-executing the recipe, using the target application, one or more times on the second container orchestrator;
• selecting the recipe based on a determination that the recipe meets or exceeds a threshold for operation on the second container orchestrator;
• and
• confirming that the selected recipe operates successfully on the second container orchestrator without failure.

A computer-implemented method for transferring a target application to a second container orchestrator, using a snapshot of a resource state of the target application from a first container orchestrator, the computer-implemented method comprising:

• executing a recipe to transfer the target application to the second container orchestrator, wherein the recipe includes an instruction to cause a change at the second container orchestrator relative to a resource involved in the transfer, the change comprising at least one of (i) changing a sequence in which the resource is restored, (ii) excluding an unrelated cluster information from a specification of the resource, (iii) changing a timing of restoration of the resource, and (iv) correcting a stale cluster information in the specification of the resource;
• re-executing a plurality of recipes including the recipe, using the target application, one or more times on the second container orchestrator;
• selecting at least one recipe in the plurality of recipes based on a determination that the at least one recipe in the plurality of recipes meets or exceeds a threshold for operation on the second container orchestrator;
• and
• confirming that the least one selected recipe in the plurality of recipes operates successfully on the second container orchestrator without failure.
