Calico - A pure layer 3 approach for Virtual Networking for highly scalable data centers

  •        3209

Project Calico represents a new approach to virtual networking, based on the same scalable IP networking principles as the Internet. Unlike other virtual networking approaches, Calico does not use overlays, instead providing a pure Layer 3 approach to data center networking. Calico is simple to deploy and diagnose, provides a rich security policy, supports both IPv4 and IPv6 and can be used across a combination of bare-metal, VM and container workloads.

ZeroTierOne - A Smart Ethernet Switch for Earth

  •    C++

ZeroTier is a smart programmable Ethernet switch for planet Earth. It replaces the physical LAN/WAN boundary with a virtual one, allowing devices of any type at any location to be managed as if they all reside in the same cloud region or data center. All traffic is encrypted end-to-end and takes the most direct path available for minimum latency and maximum performance. The goals and design of ZeroTier are inspired by among other things the original Google BeyondCorp paper and the Jericho Forum.

pms-docker - Plex Media Server Docker repo, for all your PMS docker needs.

  •    Shell

With our easy-to-install Plex Media Server software and your Plex apps, available on all your favorite phones, tablets, streaming devices, gaming consoles, and smart TVs, you can stream your video, music, and photo collections any time, anywhere, to any device. The bridge networking creates an entirely new network within the host and runs containers within there. This network is connected to the physical network via an internal router and docker configures this router to forward certain ports through to the containers within. The host networking uses the IP address of the host running docker such that a container's networking appears to be the host rather than separate. The macvlan networking creates a new virtual computer on the network which is the container. For purposes of setting up a plex container, the host and macvlan are very similar in configuration.
