How do you buy a used Linux container? A quick search of “how to buy a shipping container” will turn up a wealth of information, especially how to evaluate used ones. While all analogies are imperfect, this one is pretty good and it does highlight an interesting problem – basically, any Linux container image over
The Paths Forward In Container Portability: Part2: Code Portability Today, we discussed how there are no regression tests, there is no complete interface standard, there is definitely pain ahead if we think we can use today’s container images (level 3B) on tomorrow’s container hosts (level 3A), 10 years from now. So, what’s the solution? With
Like in the physical world of shipping containers, the OCI container image and runtime formats are critical because they allow for infrastructure and investment to happen among a bunch competing and collaborating entities. Vendors can invest in building an ecosystem of tools, orchestrators, registry servers, etc. Users can extract value from the ecosystem, move containers where

Code Portability Today In Container Portability: Part 1: A Brief History in Code Portability, we explored the genesis of code portability and visited structured computer organization to highlight the six commonly found levels in modern computing. Revisiting the six layers – nobody debates the portability of the upper two layers –Â Application Programmers know that C
A Brief History in Code Portability Do you know why you can take a Python program and run it on any computer that has a Python interpreter on it? Well, because the computer industry has made a huge amount of investment into providing portability over the last 70 years. In the beginning, computers didn’t have
The Container Host *is* the Container Engine, and Container Image Compatibility Matters Have you ever wondered, how are containers are so portable? How it’s possible to run Ubuntu containers on CentOS, or Fedora containers on CoreOS? How is it that all of this just magically works? As long as I run the docker daemon on
