This happens to work on my own development system, but is failing to work on our build server where it must be done for an automated build. Some ipv6 host configuration parameters: . With Docker single-host networking, a MySQL container can be run in an isolated environment (only reachable by containers in the same network), or an open environment (where the MySQL service is totally exposed to the outside world) or the instance simply runs with no network at all. docker localhost docker-compose Share Improve this question Follow edited at 11:01 asked at 23:33 oligofren 641 2 8 22 Is this Docker running on WSL2 or on an actual Linux machine Michael Hampton at 23:38 It's normally running on macOS and 'real' Linux when developing. 1 I am trying to make it possible to make and mount loop devices from within a container. There's no route and no gateway either (doesn't makes sense without an ipv6 address).ĭocker is started with these parameters in DOCKER_OPTS DOCKER_OPTS='-dns 8.8.8.8 -dns 8.8.4.4 -ipv6 -fixed-cidr-v6=w:x:y:z:a::/80' My docker0 bridge does NOT have a IPv6 address after restarting docker with the parameters below. willnorris/imageproxy is a caching image proxy server that we use in one of our deployments. I cannot however access the outside world from within the containers! Access the host's IP or loopback interface from Docker container. The loopback address 127.0.0.1 is generally known as. The loopback addresses are built into the IP domain system, enabling devices to transmit and receive the data packets. My host is capable of using IPv6 without any problem: Pinging the outside world works, a website running on a container (Port 80 bound to host:80) is accessible via ipv6. A loopback address is a distinct reserved IP address range that starts from 127.0.0.0 ends at 127.255.255.255 though 127.255.255.255 is the broadcast address for 127.0.0.0/8.eth0 has a statically configured address like w:x:y:z::1 in a network like w:x.y:z::/64, which is assigned to my by my hosting company. In order to prevent the master from listening on port 8080 on all network interfaces on the master machine, you may specify the loopback interface in the.Thats pretty much what the networknamespaces(7) manpage says too.

I'm having serious problems enabling IPv6 in docker. No, each container has its own loopback device.
