x86 Docker containers will not run on ARM, even if you install Docker for ARM. Docker is an entirely useless layer to support cross-architecture deployment.
Heck, even full-blown VMs (the real ones, that docker partially replaced) are mostly useless, for performance reasons.
- karakanb 8y agoThe question was not specifically around Docker. What I wonder is, why wouldn't there be a seperate layer that abstracts away these platform differences, just like Docker did for operating systems?
- timmytokyo 8y agoLike the operating system?
- karakanb 8y agoExactly, but I am not well-versed about the challanges and potential difference that might surface in kernel level and since Linus thinks it is not applicable, I was wondering if there is / would be an equivalent in the user space that would allow reproducibility for different architectures, something like architecture independent containers maybe. I would like to believe that we have come to a position where we can consider the application and platform as completely independent entities, which would eliminate these concerns regarding dev/prod parity possibly. All these questions are mostly out of my ignorance though, I am trying to understand why the architecture change would require a huge effort as long as the underlying stuff is well abstracted.
