Isa-ported container images

A computer program product for porting a software container image to a target instruction set architecture (ISA), the software container image selected for execution on a first computer, the first computer implementing the target ISA, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a first computer to perform a method comprising:

• forming, by a second computer, a ported image, the ported image capable of executing on the first computer, the forming performed in association with at least one of preparing the software container image for execution on the first computer and executing the software container image on the first computer;
• selecting, by the second computer, a source image, the source image included in the software container image;
• selecting, by the second computer, a source component, the source component included in the source image;
• determining, by the second computer, that the source component is not compatible with the target ISA, the determining based, at least in part, on the source component dependent on a first ISA, the first ISA different from the target ISA;
• and
• including, by the second computer, in the ported image an at least one first target-ISA equivalent component, the at least one first target-ISA equivalent component performing a function equivalent to at least one function of the source component, the at least one first target-ISA equivalent component compatible with the target ISA, the at least one first target-ISA equivalent component replacing, in the ported image, the source component.

A system for porting a software container image to a target instruction set architecture (ISA), the software container image selected for execution on a first computer, the first computer implementing the target ISA, the system comprising:

• a processor;
• and
• a memory in communication with the processor, wherein the system is configured to perform a method, the method comprising:
• forming a ported image, the ported image capable of executing on the first computer, the forming performed in association with at least one of preparing the software container image for execution on the first computer and executing the software container image on the first computer;
• selecting a source image, the source image included in the software container image;
• selecting a source component, the source component included in the source image;
• determining that the source component is not compatible with the target ISA, the determining based, at least in part, on the source component dependent on a first ISA, the first ISA different from the target ISA;
• and
• including in the ported image an at least one first target-ISA equivalent component, the at least one first target-ISA equivalent component performing a function equivalent to at least one function of the source component, the at least one first target-ISA equivalent component compatible with the target ISA, the at least one first target-ISA equivalent component replacing, in the ported image, the source component.
