Hi, I’d like to try macvlan networking with Rancher. But I don’t know how to add and configure the corresponding plugin. I cannot find any documentation on the topic. Please advice, if possible. Thanks, –Andrey ---

Hi @Andrey, currently Rancher supports IPsec and VXLAN networking plugins and these plugins take care of overlay networking across different hosts. To get a network driver using MACVLAN, one would have to take care of the cross host networking, IPAM, etc. Can you please elaborate on your needs so that I can assist you better? ---

Hi @leodotcloud, Thank you for your response. I needed to enable restarting containers (e.g. after host or OS crash) with same IP addresses, so that they could still be reached from non-containerized applications (pre-configured to access containerized servers by particular IPs). But seems that it’s easier to solve this problem by using symbolic address (not IPs) and Mesos DNS to resolve the names.
