It must be an IP address (or a DNS name) that is accessible from both Docker containers and, if you want to do development, from applications running on the host. This variable sets the advertised listener of the Kafka container. One disadvantage of this solution is that you cannot offer services from In order to correctly configure Eventuate Local, you must set the OS environment variable DOCKERHOSTIP. Note that all other Docker containers that you want to reach from the nginxĬontainer must also use the nginx network. Now, create a DNS record with the container’s addresses and you’ll be able toĪccess it via IPv4 and IPv6 with correct remote addresses, while still beingĪble to reach other containers: A 203.0.113.1 ( ff::1), so as to not conflict with the addresses that Docker sequentially Note that I’m using an IPv6 address from the far end of the address space Solution for my simple setup, where I want to statically configure a DNS record.ĭocker allows specifying an IPv6 address, but only when you’re using a user-defined bridge network with an IPv6 subnet carved out for the network, like so: % docker network create -subnet 2001:db8:13b:330:dd::/80 -ipv6 nginx Having addresses depend on the order in which containers come up isn’t a robust To enable IPv6, create theĬonfiguration file /etc/docker/daemon.json with the following content: ' nginxĪbove, I explained that we need to use the container’s IPv6 address directly,Īnd that the address is derived from the MAC address, which is chosen Let’s say that my provider gives me a routed IPv6 subnetĢ001:db8:13b:330::/64 and the IPv4 address 203.0.113.1. I’m using documentation-only IPs ( RFC3849Īrticle. Puzzle together from Docker’s official documentation. This article walks through the required steps, which are a bit cumbersome to This way overall network setup will become clear and easy. Above command runs nginx container with ip ‘88.99.102.115’ attached to this container, you can verify by hitting ‘88.99.102.115’ where you will be welcomed with nginx page. Proxy to, say, a Grafana instance, which is also running docker run -name cont1 -netmacvlanbridge -ip88.99.102.115 -mac-address 00:50:56:00:60:42 -itd nginx. VXLAN encapsulates MAC address over UDP packet which makes a Layer 2. Multiple virtual hosts, some of which just serve static files, while others In this lab, we will set up a topology same as the one we used to analyze the. My use-case is seemingly very simple: I want to run a webserver in a DockerĬontainer, and it should be reachable via IPv4 and IPv6.
