Open Container Initiative (OCI)
Open Container Initiative (OCI)
The Open Container Initiative is an open governance structure for the express purpose of creating open industry standards around container formats and runtimes. Established in June 2015 by Docker and other leaders in the container industry, the OCI currently contains two specifications, the runtime specification (runtime-spec) and the image specification (image-spec). The runtime specification outlines how to run a “filesystem bundle” that is unpacked on disk. At a high-level an OCI implementation would download an OCI Image then unpack that image into an OCI Runtime filesystem bundle. At this point the OCI Runtime Bundle would be run by an OCI Runtime. The Open Container Initiative (OCI) is a lightweight, open governance structure (project), formed under the auspices of the Linux Foundation, for the express purpose of creating open industry standards around container formats and runtime. The OCI was launched on June 22nd 2015 by Docker, CoreOS and other leaders. -

Prelint
Prelint
It’s a non-negotiable that shipped code matches product specs, not just that it passes code review.

It synthesises your specs, tickets, emails, call transcripts, and meeting notes into a product knowledge graph and checks every pull request against those decisions before it merges, so you see which changes quietly contradict the spec while there is still time to adjust. You spend less time re‑opening tickets, fixing last minute issues, or rolling back work that should never have shipped.Starting Price: $30/committer/month -
