What

OCI是一個標準，訂定了container的

• Runtime 標準 (start, exec, pause)
• Image 標準
• Distribution 標準

Why

The mission of the Open Container Initiative (OCI) is to promote a set of common, minimal, open standards and specifications around container technology.

OCI的出現，確保container的開發者可以專注在開發服務，不會因為

1. client
2. 應用端App stack
3. Container Technology Vender
4. CPU, hardware, OS

等等的不同，而需要使用不同的Container技術

OCI Runtime 的實作

runtime-spec/implementations.md

比較有名的是

1. runc (go, lead by docker)
2. crun (c, lead by Redhat)
