docker容器启用ipv6地址方法

Docker-Compose启用IPv6

你如果没用使用Docker-Compose，就忽略配置，以了解为主，直接去看下面的docker配置。 docker-compose.yaml 文件必须使用 version: “2.*”，version: “3.*” 不支持 enable_ipv6 配置如果已有旧的容器在运行（网络配置发生了变化），则需要先销毁容器 docker-compose down 然后再重新创建 docker-compose up仅需在network下添加如下内容即可，其他信息正常配置。

networks:      local_bridge:        enable_ipv6: true        driver: bridge        ipam:          config:            - subnet: "2409:807e::/80"

启用ipv6

说明
docker默认是不支持ipv6的，所以想要使用ipv6，就得单独开启这个功能。前提条件
主机需要具备ipv6地址并能正常使用，如下，2409开头的正规v6地址，而非fe80这种内部用的v6地址哈。

2: ens3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000    link/ether fa:16:3e:67:77:58 brd ff:ff:ff:ff:ff:ff    inet 10.241.102.245/24 brd 10.241.102.255 scope global dynamic noprefixroute ens3       valid_lft 63404sec preferred_lft 63404sec    inet6 2409:807e:58cc:114::a2d/120 scope global noprefixroute        valid_lft forever preferred_lft forever    inet6 fe80::f816:3eff:fe67:7758/64 scope link noprefixroute        valid_lft forever preferred_lft forever

执行vim /etc/docker/daemon.json 配置文件【没有这个配置文件是正常的】，写入如下内容
"fixed-cidr-v6": "2409::/80",这个后面的ip是自定义的。。。

[root@xz-docker-tes-01 ~]# cat /etc/docker/daemon.json {    "ipv6": true,    "fixed-cidr-v6": "2409::/80",    "experimental": true,    "ip6tables": true}[root@xz-docker-tes-01 ~]# 

重启docker生效

重启不报错，实际上此时docker就能支持ipv6了。

[root@xz-docker-tes-01 ~]# systemctl restart docker[root@xz-docker-tes-01 ~]# systemctl status docker● docker.service - Docker Application Container Engine   Loaded: loaded (/usr/lib/systemd/system/docker.service; disabled; vendor preset: disabled)   Active: active (running) since Fri 2023-12-01 11:40:31 CST; 9s ago     Docs: https://docs.docker.com Main PID: 14470 (dockerd)    Tasks: 13   Memory: 47.3M   CGroup: /system.slice/docker.service           └─14470 /usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock

创建一个ipv6的docker网络

这一步其实是不需要做的，因为，不使用这个网络的docker容器，也可以正常使用ipv6地址。
我这多做一步是为了做测试而已。具体区别见下面测试说明。【测试后，我觉得这个没意义】

[root@xz-docker-tes-01 ~]# docker network create -d bridge --ipv6 --subnet "2409:807e::/80" ipv6_bridge09663034b21493f64d2484dc21923a789bc8ac51c403d422e397435df74f204b[root@xz-docker-tes-01 ~]#

创建好后的网络信息如下

[root@xz-docker-tes-01 ~]# docker network  listNETWORK ID     NAME          DRIVER    SCOPEbf1937081949   bridge        bridge    locale98be3082c27   host          host      local09663034b214   ipv6_bridge   bridge    local7cee98cd58fe   none          null      local[root@xz-docker-tes-01 ~]# 

创建容器测试v6地址

使用ipv6的网络创建容器

我这使用上面创建的一个ipv6的网络做测试测试

[root@xz-docker-tes-01 ~]# docker run -dit --name=v6 --restart=always --network=ipv6_bridge hub.c.163.com/library/centos:latest 49af16d7dd9c63afd2a43b24b6dfdb8b39d70ef8e39c1d1c067dcbe28c242efa[root@xz-docker-tes-01 ~]# [root@xz-docker-tes-01 ~]# docker psCONTAINER ID   IMAGE                                 COMMAND       CREATED         STATUS         PORTS     NAMES49af16d7dd9c   hub.c.163.com/library/centos:latest   "/bin/bash"   3 seconds ago   Up 2 seconds             v6[root@xz-docker-tes-01 ~]# 

容器内 ping其他v6地址和网关都能通，一切正常

[root@xz-docker-tes-01 ~]# docker exec -it v6 bash[root@49af16d7dd9c /]# lsanaconda-post.log  bin  dev  etc  home  lib  lib64  lost+found  media  mnt  opt  proc  root  run  sbin  srv  sys  tmp  usr  var[root@49af16d7dd9c /]#[root@49af16d7dd9c /]# ping6 2409:807e:58cc:114::a2dPING 2409:807e:58cc:114::a2d(2409:807e:58cc:114::a2d) 56 data bytes64 bytes from 2409:807e:58cc:114::a2d: icmp_seq=1 ttl=64 time=0.459 ms64 bytes from 2409:807e:58cc:114::a2d: icmp_seq=2 ttl=64 time=0.093 ms64 bytes from 2409:807e:58cc:114::a2d: icmp_seq=3 ttl=64 time=0.090 ms^C--- 2409:807e:58cc:114::a2d ping statistics ---3 packets transmitted, 3 received, 0% packet loss, time 2058msrtt min/avg/max/mdev = 0.090/0.214/0.459/0.173 ms[root@49af16d7dd9c /]# ping6 2409:807e:58cc:114::a01PING 2409:807e:58cc:114::a01(2409:807e:58cc:114::a01) 56 data bytes64 bytes from 2409:807e:58cc:114::a01: icmp_seq=1 ttl=63 time=10.2 ms64 bytes from 2409:807e:58cc:114::a01: icmp_seq=2 ttl=63 time=2.04 ms64 bytes from 2409:807e:58cc:114::a01: icmp_seq=3 ttl=63 time=2.23 ms64 bytes from 2409:807e:58cc:114::a01: icmp_seq=4 ttl=63 time=2.35 ms^C--- 2409:807e:58cc:114::a01 ping statistics ---4 packets transmitted, 4 received, 0% packet loss, time 3004msrtt min/avg/max/mdev = 2.048/4.208/10.200/3.461 ms[root@49af16d7dd9c /]# [root@49af16d7dd9c /]# exitexit[root@xz-docker-tes-01 ~]# 

该容器的网络容器里面呢，也会有一个ipv6地址，主机虽然能ping通，但这个ip是容器专属的，

[root@xz-docker-tes-01 ~]# docker inspect v6 | grep "IPv6"            "LinkLocalIPv6Address": "",            "LinkLocalIPv6PrefixLen": 0,            "SecondaryIPv6Addresses": null,            "GlobalIPv6Address": "",            "GlobalIPv6PrefixLen": 0,            "IPv6Gateway": "",                    "IPv6Gateway": "2409:807e::1",                    "GlobalIPv6Address": "2409:807e::2",                    "GlobalIPv6PrefixLen": 80,[root@xz-docker-tes-01 ~]# [root@xz-docker-tes-01 ~]# ping 2409:807e::2PING 2409:807e::2(2409:807e::2) 56 data bytes64 bytes from 2409:807e::2: icmp_seq=1 ttl=64 time=0.695 ms64 bytes from 2409:807e::2: icmp_seq=2 ttl=64 time=0.090 ms^C--- 2409:807e::2 ping statistics ---2 packets transmitted, 2 received, 0% packet loss, time 50msrtt min/avg/max/mdev = 0.090/0.392/0.695/0.303 ms[root@xz-docker-tes-01 ~]# 

容器内能ping通同样用这个网络创建的其他容器【但默认容器直接网络是隔离的哈】，具体这个v6地址的用途自行探索吧。

[root@xz-docker-tes-01 ~]# docker exec -it v6 bash[root@49af16d7dd9c /]# ping6 2409:807e::3PING 2409:807e::3(2409:807e::3) 56 data bytes64 bytes from 2409:807e::3: icmp_seq=1 ttl=64 time=0.346 ms64 bytes from 2409:807e::3: icmp_seq=2 ttl=64 time=0.108 ms64 bytes from 2409:807e::3: icmp_seq=3 ttl=64 time=0.107 ms^C--- 2409:807e::3 ping statistics ---3 packets transmitted, 3 received, 0% packet loss, time 2085msrtt min/avg/max/mdev = 0.107/0.187/0.346/0.112 ms[root@49af16d7dd9c /]# 

使用普通网络创建容器测试

进入以后，能ping通网关和其他v6地址，没问题。

[root@xz-docker-tes-01 ~]# docker run --name=test1 -it hub.c.163.com/library/centos[root@d866a511db84 /]# ping6 2409:807e:58cc:114::a17PING 2409:807e:58cc:114::a17(2409:807e:58cc:114::a17) 56 data bytes64 bytes from 2409:807e:58cc:114::a17: icmp_seq=1 ttl=63 time=1.85 ms64 bytes from 2409:807e:58cc:114::a17: icmp_seq=2 ttl=63 time=0.782 ms64 bytes from 2409:807e:58cc:114::a17: icmp_seq=3 ttl=63 time=0.793 ms64 bytes from 2409:807e:58cc:114::a17: icmp_seq=4 ttl=63 time=0.891 ms^C--- 2409:807e:58cc:114::a17 ping statistics ---4 packets transmitted, 4 received, 0% packet loss, time 3053msrtt min/avg/max/mdev = 0.782/1.080/1.855/0.449 ms[root@d866a511db84 /]# [root@d866a511db84 /]# ping6 2409:807e:58cc:114::a01PING 2409:807e:58cc:114::a01(2409:807e:58cc:114::a01) 56 data bytes64 bytes from 2409:807e:58cc:114::a01: icmp_seq=1 ttl=63 time=13.3 ms64 bytes from 2409:807e:58cc:114::a01: icmp_seq=2 ttl=63 time=1.85 ms^C--- 2409:807e:58cc:114::a01 ping statistics ---3 packets transmitted, 3 received, 0% packet loss, time 2003msrtt min/avg/max/mdev = 1.716/5.648/13.378/5.466 ms[root@d866a511db84 /]# 

默认生成的，没有这个v6地址的，但不影响使用ipv6.

[root@xz-docker-tes-01 ~]# docker inspect test1 | grep "IP"            "LinkLocalIPv6Address": "",            "LinkLocalIPv6PrefixLen": 0,            "SecondaryIPAddresses": null,            "SecondaryIPv6Addresses": null,            "GlobalIPv6Address": "2409::242:ac11:2",            "GlobalIPv6PrefixLen": 80,            "IPAddress": "172.17.0.2",            "IPPrefixLen": 16,            "IPv6Gateway": "2409::1",                    "IPAMConfig": null,                    "IPAddress": "172.17.0.2",                    "IPPrefixLen": 16,                    "IPv6Gateway": "2409::1",                    "GlobalIPv6Address": "2409::242:ac11:2",                    "GlobalIPv6PrefixLen": 80,[root@xz-docker-tes-01 ~]# 

创建一个nginx容器用ipv6地址访问测试

容器创建

先创建一个映射端口的nginx容器

[root@xz-docker-tes-01 ~]# docker run -dit --name=nginx --restart=always -p 80:80 --network=ipv6_bridge nginx4a175fb0754961537b23111bab1251e9c9f36645e9936f07c5daeea28af4d898[root@xz-docker-tes-01 ~]# netstat -ntlp | grep 80 tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      16074/docker-proxy  tcp6       0      0 :::80                   :::*                    LISTEN      16088/docker-proxy  [root@xz-docker-tes-01 ~]#

我是指定了创建的ipv6网络的【其实不指定也一样，不影响外部访问的】

[root@xz-docker-tes-01 ~]# docker inspect nginx | grep "IPv6"            "LinkLocalIPv6Address": "",            "LinkLocalIPv6PrefixLen": 0,            "SecondaryIPv6Addresses": null,            "GlobalIPv6Address": "",            "GlobalIPv6PrefixLen": 0,            "IPv6Gateway": "",                    "IPv6Gateway": "2409:807e::1",                    "GlobalIPv6Address": "2409:807e::3",                    "GlobalIPv6PrefixLen": 80,[root@xz-docker-tes-01 ~]#

ipv4地址验证

直接浏览器输入ipv4的地址，不报错就行【我下面显示ccx是因为我修改过nginx的默认文件内容了】

ipv6地址访问验证

验证ipv6地址之前，需要保证你测试的主机上已经配置有ipv6地址并且能正常使用
首先测试能否ping通目标ipv6地址【就上面搭建ipv6的主机v6地址，是主机，而非容器的啊】
然后网页直接输入v6地址【就上面搭建ipv6的主机v6地址，是主机，而非容器的啊】 访问格式[ipv6addr] 【注意，v6地址用中括号扩起来的】其实下面内容就是nginx默认的内容，因为没有放任何东西，所以就会显示nginx界面，反正没报错就是正常的。

修改nginx容器网页内容

xian进入nginx容器内部

[root@xz-docker-tes-01 ~]# docker exec -it nginx bashroot@4a175fb07549:/#

因为不知道容器的http默认文件在哪里，所以可以用find搜索

root@4a175fb07549:/# find / -name htmlfind: '/proc/32/map_files': Permission deniedfind: '/proc/33/map_files': Permission deniedfind: '/proc/34/map_files': Permission deniedfind: '/proc/35/map_files': Permission denied/usr/share/nginx/htmlroot@4a175fb07549:/#

通过搜索已知html路径为：/usr/share/nginx/html
那么就可以去修改了噻【懂了吧，想要显示啥内容，替换这个index.html文件就行了】

root@4a175fb07549:/usr/share/nginx/html# ls50x.html  index.htmlroot@4a175fb07549:/usr/share/nginx/html# vi index.html bash: vi: command not foundroot@4a175fb07549:/usr/share/nginx/html# vim index.html bash: vim: command not foundroot@4a175fb07549:/usr/share/nginx/html# cat index.html <!DOCTYPE html><html><head><title>Welcome to nginx!</title><style>    body {        width: 35em;        margin: 0 auto;        font-family: Tahoma, Verdana, Arial, sans-serif;    }</style></head><body><h1>Welcome to nginx!</h1><p>If you see this page, the nginx web server is successfully installed andworking.

如我上面，将ccx内容写入了index.html文件，那么正常情况，网页就只会显示ccx这3个字母
