> Crosby explained that a registry would still be needed to handle the naming of images, but the content address blobs could be transferred from one machine to another without the need to directly interact with the registry. In the P2P model for image delivery, a registry could send a container image to one node, and then users could share and distribute images using something like BitTorrent sync.

I believe this is the basic concept of Uber's Kraken project: https://github.com/uber/kraken

I think it's a really clever idea, but I can also predict that a lot of enterprise companies will hear "bittorrent" and nope their way out of it.

Or way simpler: https://github.com/docker/distribution/pull/2906

Unfortunately the whole project seems abandoned...

I don't think many non-tech savvy people even know what BitTorrent is. So its mention is not going to trigger much one way or another.

The only enterprises that would have an issue with are going to be companies in the media space.

Enterprises tend to have tech staff. Thousands is not atypical. I assume some of them have heard of it.

The future of Docker containers is a slow death now that there are better container solutions that provide more benefits and less bloat. Docker had great engineers and developers, but terrible management.

For the majority of people and companies containers == docker. Mostly wrapped by something k8s or one of the cloud container or running locally on your pc/laptop . Yeah some people are using rkt some are using lxc but that’s the absolute fringe minority (no disrespect intended)

I would love to read more about these solutions and their benefits over Docker!

Podman is one I am thinking of primarily, with the biggest benefit being first-class rootless integration:

What are current overall better container solutions than Docker now, which are adopted in companies worldwide?

techntoke 7 years ago | | |

Podman for Docker-specific, and cri-o for K8S.

Kind of like how Dropbox doesn't stand a chance because rsync or some of the various competitors that are cheaper and better?

The past is strewn with dead technology that was superior in every way to the status quo. But adoption and network effect is very powerful.

Just look at all the superior alternatives to Facebook that have come and gone.

techntoke 7 years ago | | |

Not at all. There are some great alternatives to Dropbox though, including Google Drive, Syncthing and Nextcloud.
