Weave Net - Weaving Containers into Applications
Weave Net creates a virtual network that connects Docker containers across multiple hosts and enables their automatic discovery. With Weave Net, portable microservices-based applications consisting of multiple containers can run anywhere: on one host, multiple hosts or even across cloud providers and data centers. Applications use the network just as if the containers were all plugged into the same network switch, without having to configure port mappings, ambassadors or links.
Services provided by application containers on the weave network can be exposed to the outside world, regardless of where they are running. Similarly, existing internal systems can be opened to accept connections from application containers irrespective of their location.
VXLAN is an overlay network to encapsulate Ethernet traffic over an existing (highly available and scalable, possibly the Internet) IP network while accomodating a very large number of tenants. It is defined in RFC 7348. For an uncut introduction on its use with Linux, have a look at my “VXLAN & Linux” post.
VXLAN is an overlay network to carry Ethernet traffic over an existing (highly available and scalable) IP network while accommodating a very large number of tenants. It is defined in RFC 7348.
Starting from Linux 3.12, the VXLAN implementation is quite complete as both multicast and unicast are supported as well as IPv6 and IPv4. Let’s explore the various methods to configure it.
