如何使用docker-compose分配IPv6地址 [英] How to assign IPv6 address with docker-compose
问题描述
我在Ubuntu 16.04和docker-compose 1.8.1上使用docker 1.12.1。我正在尝试从 https:// docs获取Compose文件.docker.com / compose / compose-file /#ipv4-address-ipv6-address 即可运行。作为参考,我创建了 docker-compose.yml
,其内容如下:
I am using docker 1.12.1 on Ubuntu 16.04, and docker-compose 1.8.1. I am trying to get the Compose file from https://docs.docker.com/compose/compose-file/#ipv4-address-ipv6-address to run. For reference, I created docker-compose.yml
with the following content:
version: '2'
services:
app:
image: busybox
command: ifconfig
networks:
app_net:
ipv4_address: 172.16.238.10
ipv6_address: 2001:3984:3989::10
networks:
app_net:
driver: bridge
driver_opts:
com.docker.network.enable_ipv6: "true"
ipam:
driver: default
config:
- subnet: 172.16.238.0/24
gateway: 172.16.238.1
- subnet: 2001:3984:3989::/64
gateway: 2001:3984:3989::1
现在,运行 docker-compose up
产生
Creating network "tmp_app_net" with driver "bridge"

未分配IPv6地址。
我已经尝试过:
- 使用
-ipv6启动docker daemon
- 使用
-ipv6 --fixed-cidr-v6 = 2001:3984:3989 :: / 64启动docker守护进程
- 请注意,
docker run -it busybox ifconfig
实际上给了我一个IPv6地址(来自-fixed-cidr
子网,该子网已分配给默认的bridge
网络)
- 请注意,
- Starting the docker daemon with
--ipv6
- Starting the docker daemon with
--ipv6 --fixed-cidr-v6="2001:3984:3989::/64"
- Note that
docker run -it busybox ifconfig
actually gives me an IPv6 address here (from the--fixed-cidr
subnet which is assigned to the defaultbridge
network)
- Note that
没有成功。有想法吗?
推荐答案
事实证明,这确实是一个docker-compose 错误,该错误将在1.9.0版中修复。
It turns out this is indeed a docker-compose bug that is going to be fixed in 1.9.0.
同时,有一个一种解决方法,方法是使用 docker network
命令创建自定义网络:
Meanwhile, there is a workaround by creating a custom network with the docker network
command:
docker network create --subnet=172.16.2.0/24 --gateway=172.16.2.1 --ipv6 --subnet=<myV6Network/subnet> dockerbridge
...然后可以在组成 docker的内部使用。 yml
通过编写
... which can then be made available inside docker-composed.yml
by writing
networks:
dockerbridge:
external:
name: dockerbridge
