Let us verify if MacVLAN network scope holds this container: $docker service create –replicas 1 –name wordpressdb1 –network swarm-macvlan –env MYSQL_ROOT_PASSWORD=collab123 –env MYSQL_DATABASE=wordpress mysql We will be creating 2 services – wordpressapp and wordpressdb1 and attach it to “swarm-macvlan” network as shown below: Let us go ahead and deploy WordPress application. manager1=> $sudo docker network create -d macvlan -scope swarm -config-from collabnet swarm-macvlanĭeploying a service to the swarm-macvlan network: Instantiating the macvlan network globally This is one method of IPAM to guarantee unique IP allocations. ip-range is used to specify a pool of IP addresses that is a subset of IPs from the subnet. The config holds host-specific information, such as the subnet allocated for this host’s containers.
#Docker network attachable driver
Installing Docker 17.06 on all the Nodes:Īttention VirtualBox Users:– In case you are using VirtualBox, the MACVLAN driver requires the network and interfaces to be in promiscuous mode.Ī local network config is created on each host. I have tested it on bare metal system and VirtualBox and it works equally great. To test-drive MacVLAN under Swarm Mode, I will leverage the existing 3 node Swarm Mode clusters on my VMware ESXi system. 10representing VLAN 10), or even a bonded host adaptor which bundles two Ethernet interfaces into a single logical interface. This interface can be a physical interface such as eth0, a sub-interface for 802.1q VLAN tagging like eth0.10 (. It’s use cases includes very low latency applications and networking design that requires containers be on the same subnet as and using IPs as the external host network.The macvlan driver uses the concept of a parent interface. It has positive performance implications by virtue of having a very simple and lightweight architecture. MACVLAN offers a number of unique features and capabilities. It also allows containers to receive routable IP addresses that are on the subnet of the physical network. In case you’re new , the MACVLAN driver provides direct access between containers and the physical network. This is a great news for all Docker Networking enthusiasts. Previously only swarm scope networks like overlay were supported. Some examples of these are bridge, host, and macvlan though any local scope network driver, built-in or plug-in, will work with Swarm. This includes any local scope network driver. Under the new upcoming 17.06 release, Docker provides support for local scope networks in Swarm. But one of the notable and most awaited feature include support of swarm-mode services with node-local networks such as macvlan, ipvlan, bridge and host. Few of my favourites includes support for Secrets on Windows, allows specifying a secret location within the container, adds -format option to docker system df command, adds support for placement preference to docker stack deploy, adds monitored resource type metadata for GCP logging driver and adding build & engine info prometheus metrics to list a few. It brings numerous new features & enablements under this new upcoming release.
