### IPv6

[Enable IPv6 support](https://forums.docker.com/t/docker-user-chain-for-ip6tables/133961/3) in Docker by specifying ULA range (RFC 4193) in `/etc/docker/daemon.json`

"experimental": true,
|
||||
"ipv6": true,
|
||||
"ip6tables": true,

@ -236,36 +220,6 @@ This command does the following things:
|
|||
- Back up the file `/etc/ufw/after.rules`
|
||||
- Append the rules of UFW and Docker at the end of the file
|
||||
|
||||
#### IPv6 support
|
||||
|
||||
`ufw-docker` also supports IPv6 networks and will update `/etc/ufw/after6.rules` when necessary.
|
||||
|
||||
### Using the `--docker-subnets` option
|
||||
|
||||
You can use the `--docker-subnets` option to customize which subnets will be allowed to communicate with Docker containers.
|
||||
This option applies to both IPv4 and IPv6 networks.
|
||||
|
||||
* If the option is **not provided**, only standard private LAN subnets will be used
|
||||
(IPv4: `10.0.0.0/8`, `172.16.0.0/12`, `192.168.0.0/16`; IPv6: `fd00::/8`)
|
||||
* If `--docker-subnets` is given **without any arguments**, all Docker network subnets will be detected and used automatically.
|
||||
**Note:** If you add or remove Docker networks, you need to run `ufw-docker install --docker-subnets` again to update the firewall rules according to the latest network configuration.
|
||||
* If one or more subnets are specified, only these subnets will be used (you can list multiple subnets, separated by spaces; each should be in CIDR format).
|
||||
The subnets can include networks not managed by Docker itself.
|
||||
|
||||
#### Examples
|
||||
|
||||
# Use default private LAN subnets (IPv4: 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16; IPv6: fd00::/8)
|
||||
ufw-docker install
|
||||
|
||||
# Auto-detect and use all Docker network subnets (both IPv4 and IPv6)
|
||||
ufw-docker install --docker-subnets
|
||||
|
||||
# Only allow these specified subnets to communicate with Docker containers
|
||||
ufw-docker install --docker-subnets 192.168.207.0/24 10.207.0.0/16 fd00:cf::/64
|
||||
|
||||
|
||||
You can use the same options with `ufw-docker check` to preview the changes before applying them.
|
||||
|
||||
#### Install for Docker Swarm mode
|
||||
|
||||
We can only use this script on manager nodes to manage firewall rules when using in Swarm mode.

|
||||
### 支持 IPv6
|
||||
|
||||
要让 Docker Engine [启用 IPv6 的支持](https://forums.docker.com/t/docker-user-chain-for-ip6tables/133961/3). 你需要在 `/etc/docker/daemon.json` 文件中启用相关设置，并分配一个 ULA（唯一本地地址，RFC 4193）地址段作为 IPv6 网络范围。
|
||||
|
||||
```json
|
||||
{
|
||||
"experimental": true,
|
||||
"ipv6": true,
|
||||
"ip6tables": true,
|
||||
"fixed-cidr-v6": "fd00:dead:beef::/48"
|
||||
}
|
||||
```
|
||||
|
||||
#### 结论
|
||||
|
||||
如果我们正在使用老版本的 Ubuntu，我们可以使用 `ufw-user-input`。但是要小心避免把不该暴露的服务暴露出去。

- 备份文件 `/etc/ufw/after.rules`
|
||||
- 把 UFW 和 Docker 的相关规则添加到文件 `after.rules` 的末尾
|
||||
|
||||
#### IPv6 支持
|
||||
|
||||
`ufw-docker` 也支持 IPv6 网络，并会在需要时自动更新 `/etc/ufw/after6.rules` 文件。
|
||||
|
||||
### 使用 `--docker-subnets` 选项
|
||||
|
||||
你可以使用 `--docker-subnets` 选项，自定义允许与 Docker 容器通信的子网。
|
||||
该选项同时适用于 IPv4 和 IPv6 网络。
|
||||
|
||||
* 如果**未指定**该选项，只会使用标准的私有局域网子网
|
||||
（IPv4：`10.0.0.0/8`、`172.16.0.0/12`、`192.168.0.0/16`；IPv6：`fd00::/8`）
|
||||
* 如果指定了 `--docker-subnets` 但**未带参数**，会自动检测并使用所有 Docker 网络的子网。
|
||||
**注意：** 如果你对 Docker 网络进行了新增或删除操作，需要重新运行 `ufw-docker install --docker-subnets`，以便根据最新的网络配置更新防火墙规则。
|
||||
* 如果指定了一个或多个子网，则只会使用这些子网（你可以用空格分隔多个子网，每个子网应为 CIDR 格式）。
|
||||
这些子网可以包括非 Docker 管理的网络。
|
||||
|
||||
#### 示例
|
||||
|
||||
# 使用默认的私有局域网子网（IPv4：10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16；IPv6：fd00::/8）
|
||||
ufw-docker install
|
||||
|
||||
# 自动检测并使用所有 Docker 网络的子网（同时支持 IPv4 和 IPv6）
|
||||
ufw-docker install --docker-subnets
|
||||
|
||||
# 仅允许这些指定的子网与 Docker 容器通信
|
||||
ufw-docker install --docker-subnets 192.168.207.0/24 10.207.0.0/16 fd00:cf::/64
|
||||
|
||||
#### 为 Docker Swarm 环境安装
|
||||
|
||||
仅仅可以在管理节点上使用 `ufw-docker` 这个脚本来管理防火墙规则。

|

Specify which subnets should be used when configuring firewall rules for Docker containers and any allowed networks that communicate with containers.
|
||||
|
||||
- If this option is not provided, only standard private LAN subnets are used (RFC1918 for IPv4 and fd00::/8 for IPv6).
|
||||
- If --docker-subnets is given without any arguments, all Docker network subnets will be automatically detected and used.
|
||||
- If one or more subnets are specified, these subnets will be used for firewall rules, and they can include any networks that need to communicate with containers—not just the subnets configured by the Docker engine.
|
||||
You can specify multiple subnets separated by spaces (each in CIDR format).
|
||||
|
||||
Examples:
|
||||
- ufw-docker $1
|
||||
Use only standard private subnets (default behavior).
|
||||
- IPv4 subnets: 10.0.0.0/8 172.16.0.0/12 192.168.0.0/16
|
||||
- IPv6 subnet: fd00::/8
|
||||
|
||||
- ufw-docker $1 --docker-subnets
|
||||
Auto-detect and use all Docker network subnets.
|
||||
|
||||
- ufw-docker $1 --docker-subnets 10.207.0.0/16 192.168.207.0/24 fd00:cf::/64
|
||||
Use only the specified subnets, including those outside of Docker’s own configuration, for all networks that should be allowed to communicate with containers.
