Also used by the docker ip driver to delete the network route if delnetroute is set to true.

Netns docker for mac mac#

Next is the specific namespace in which the command should be run (in this case, the blue namespace). If specified, use this mac address in the netns. Let’s break it down: The first part, ip netns exec, is how you execute commands in a different network namespace. #network docker run -detach -name= -label=ntainer#network -net=none -tty -cgroup-parent /opensvc.slice/demomac.slice/container.slice/ markeijsermans/debug ip netns exec blue ip link list Whoa That’s a bit of a complicated command. To list all interfaces that are part of the root network namespace, run: Let’s assign the eth1-ns1 and. momac /bin/echo 0 >/sys/fs/cgroup/cpuset/opensvc.slice/demomac.slice/ms In order to connect both network namespaces, let’s first create a virtual pair of interfaces for each namespace: The preceding two commands create four virtual interfaces eth1-ns1, eth1-ns2 and veth-ns1, veth-ns2. momac /bin/echo 0-7 >/sys/fs/cgroup/cpuset/opensvc.slice/demomac.slice/cpuset.cpus A virtual nic is added into the docker container network namespace using the parameters declared into the ip#0 section. It looks like drone.io might, because it uses a superset of docker-compose, but I haven't tried it yet.Ī further restriction is that this has to play nice on an existing Docker host with running containers, and only manage specific containers/networks.Īssuming there are tools that will do it, we also have to integrate them with our pipelines, ideally Codefresh, or Jenkins :)Ĭreate a simple opensvc service om demomac createīelow is an example config using a bridge named "dummy-bridge".

Netns docker for mac upgrade#

So the question is, are there any lightweight orchestration tools we can use to deploy and upgrade containers which can set a MAC address? Kubernetes doesn't support it, and looking around, it's hard to get a straight answer on what does. So something like the following would get you what you want: docker network create -drivermacvlan -subnet192.168.0.0/16 -o parentvirbr0 mynet. Using docker-compose in production isn't advisable either. If that is the case, the answer is to use a macvlan network, which allows you to attach a docker network directly to a host device. This was fine with a handful of applications, occasionally adding a new one, but we're trying to scale up and deploy more rapidly, in line with our k8s pipelines, so the hand-rolled deployments aren't working out, we want more automation and configuration as code.

Otherwise, where we're not limited by archaic licence models, we use Kubernetes. So far, we've been able to use this well enough with docker-compose configurations matching that MAC address, across multiple containers/apps each with their own docker network, and this apparently doesn't violate the licence terms. 1 bridge99 docker network create -d bridge -subnet 172.31.99.
