Creationline and Rainlab Open Source “Beiran”,
Software to Share Container Images for Docker and Kubernetes

--- Removing Bottleneck in Container Environment ---

We, Creationline Inc. (Head Office: Tokyo, CEO and Representative Director: Tadahiro Yasuda), and our partner, Rainlab Inc. (Head Office: Tokyo, Lead Engineer: Furkan Mustafa) are happy to announce that we will start providing “Beiran(https://beiran.io/)“ as an open source software. “Beiran” is a software for sharing container images that leverages P2P technology, and is compatible with both Docker and Kubernetes*. Since it is still in heavy development stage, from this point onwards, we will be welcoming new contributors for its further development.
*Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications.

■ Background
The more you use Docker/Kubernetes, the more issues you face regarding a large-scale container environment operation.
While using these technologies enables applications to start up and running almost immediately by Docker container, downloading Docker images has been a bottleneck for its startup speed.
Additionally, as Docker Registry (the system to manage Docker images) becomes burdened, the system occasionally requires some load balancer tweaking.

“Beiran” leverages P2P technology to speed up retrieving application images (i.e. downloading Docker images). In case the other servers within the network already have some of the subjected images, Beiran downloads the images in a distributed and paralleled way from such servers within the network, instead of from the container image server on the Internet.
This is how “Beiran” can remove the bottleneck when using Docker/Kubernetes and enables applications to start up and running almost immediately in the large-scale container environment.
