- Problem solved
- Before the OCI, the burgeoning container ecosystem faced fragmentation, with different container platforms (like Docker and CoreOS's rkt) implementing their container technologies in divergent ways. This lack of a common standard led to potential vendor lock-in, made container images and runtimes incompatible across systems, and hindered the growth of a truly portable and interoperable container landscape. The OCI solved this by providing clear, open specifications that all container implementers could adhere to.
- Platforms
- macOS (via virtual machines running Linux-based OCI runtimes), Windows (for Windows container implementations adhering to OCI concepts), Linux (as the primary operating system for container execution)
