 22 | 
 23 | Selects an address from the specified network interface or via an external
 24 | command and updates A or AAAA records at Cloudflare for the configured domains.
 25 | Supports both IPv4 and IPv6.
 26 | 
 27 | Required configuration options
 28 | --------------------------------------------------------------------------------
 29 | 
 30 | --iface:   network interface name to look up for an address
 31 |   or
 32 | --ipcmd:   shell command to run to get the address, should return one address
 33 |            per line. Uses https://github.com/mvdan/sh as the shell.
 34 |            Examples:
 35 |              - curl -fsSL https://api6.ipify.org
 36 |              - echo -e "127.0.0.1\n127.0.0.2"
 37 | 
 38 | --domains: one or more domain names to assign the address to
 39 | --token:   Cloudflare API token with edit access rights to the DNS zone
 40 | 
 41 | IPv6 address selection
 42 | --------------------------------------------------------------------------------
 43 | 
 44 | When multiple IPv6 addresses are found on the interface or received from the
 45 | external command (e.g., when using --ipcmd), the following rules are used to
 46 | select the one to use:
 47 |     1. Only global unicast addresses (GUA) and unique local addresses (ULA) are
 48 |        considered.
 49 |     2. GUA addresses are preferred over ULA addresses.
 50 |     3. Unique EUI-64 addresses are preferred over randomly generated addresses.
 51 |     4. If priority subnets are specified, addresses from the subnet with the
 52 |        highest priority are selected. The priority is determined by the order of
 53 |        subnets specified on the command line or in the config file.
 54 | 
 55 | IPv4 address selection
 56 | --------------------------------------------------------------------------------
 57 | 
 58 | When multiple IPv4 addresses are found on the interface or received from the
 59 | external command (e.g., when using --ipcmd), the following rules are used to
 60 | select the one to use:
 61 |     1. All IPv4 addresses are considered.
 62 |     2. Public addresses are preferred over Shared Address Space (RFC 6598)
 63 |        addresses.
 64 |     3. Shared Address Space addresses are preferred over private addresses.
 65 |     4. Private addresses are preferred over loopback addresses.
 66 |     5. If priority subnets are specified, addresses from the subnet with the
 67 |        highest priority are selected. The priority is determined by the order of
 68 |        subnets specified on the command line or in the config file.
 69 | 
 70 | Non-public addresses are logged as warnings but are still used. They can be
 71 | useful in private networks or when using a VPN.
 72 | 
 73 | NOTE: Cloudflare doesn't allow proxying of records with non-public addresses.
 74 | 
 75 | Daemon mode
 76 | --------------------------------------------------------------------------------
 77 | 
 78 | By default, the program runs once and exits. This mode of operation can be
 79 | changed by setting the --run-every flag to a duration greater than 1m. In this
 80 | case, the program will run repeatedly, waiting the duration between runs. It
 81 | will stop if killed or if failed.
 82 | 
 83 | State file
 84 | --------------------------------------------------------------------------------
 85 | 
 86 | Setting --state-file makes the program to retain the previously used address
 87 | between runs to avoid unnecessary calls to the Cloudflare API.
 88 | 
 89 | The value is used as the state file path. When used with an empty value, the
 90 | state file is named after the interface name and the domains, and is stored
 91 | either in the current directory or in the directory specified by the
 92 | STATE_DIRECTORY environment variable.
 93 | 
 94 | The STATE_DIRECTORY environment variable is automatically set by systemd. It
 95 | can be set manually when running the program outside of systemd.
 96 | 
 97 | Multihost mode (EXPERIMENTAL)
 98 | --------------------------------------------------------------------------------
 99 | 
100 | In this mode, it is possible to assign multiple addresses to a single or
101 | multiple domains. For correct operation, this mode must be enabled on all hosts
102 | participating in the same domain and different host-ids must be specified for
103 | each host (see --host-id option). This mode is enabled by passing --multihost
104 | flag.
105 | 
106 | In the multihost mode, the program will manage only the DNS records that have
107 | the same host-id as the one specified on the command line or in the config file.
108 | If an existing record has no host-id but has the same address as the target one,
109 | it will be claimed by this host via setting the corresponding host-id. Any other
110 | records will be ignored. This allows multiple hosts to share the same domain
111 | without interfering with each other. The host-id is stored in the Cloudflare DNS
112 | comments field (see https://developers.cloudflare.com/dns/manage-dns-records/reference/record-attributes/).
113 | 
114 | Persistent configuration
115 | --------------------------------------------------------------------------------
116 | 
117 | The program can be configured using a config file. The default location is
118 | $HOME/.cloudflare-dynamic-dns.yaml. The config file location can be overridden
119 | using the --config flag. The config file format is YAML. The following options
120 | are supported (with example values):
121 | 
122 |     # === required fields
123 |     # either iface or ipcmd must be specified
124 |     iface: eth0
125 |     # ipcmd: curl -fsSL https://api6.ipify.org
126 |     token: cloudflare-api-token
127 |     domains:
128 |       - example.com
129 |       - "*.example.com"
130 |     # === optional fields
131 |     # --- mode
132 |     stack: ipv6
133 |     # --- UI
134 |     log-level: info
135 |     # --- logic
136 |     priority-subnets:
137 |       - 2001:db8::/32
138 |       - 2001:db8:1::/48
139 |     multihost: true
140 |     host-id: homelab-node-1
141 |     # --- DNS record details
142 |     proxy: enabled
143 |     ttl: 180
144 |     # --- daemon mode
145 |     run-every: 10m
146 |     state-file: /tmp/cfddns-eth0.state
147 | 
148 | Environment variables
149 | --------------------------------------------------------------------------------
150 | 
151 | The configuration options can be specified as environment variables. To make an
152 | environment variable name, prefix a flag name with CFDDNS_, replace dashes with
153 | underscores, and convert to uppercase. List values are specified as a single
154 | string containing elements separated by spaces.
155 | For example:
156 | 
157 |     CFDDNS_CONFIG=/path/to/config.yaml
158 |     CFDDNS_IFACE=eth0
159 |     CFDDNS_IPCMD='curl -fsSL https://api6.ipify.org'
160 |     CFDDNS_TOKEN=cloudflare-api-token
161 |     CFDDNS_DOMAINS='example.com *.example.com'
162 |     CFDDNS_STACK=ipv6
163 |     CFDDNS_LOG_LEVEL=info
164 |     CFDDNS_PRIORITY_SUBNETS='2001:db8::/32 2001:db8:1::/48'
165 |     CFDDNS_MULTIHOST=true
166 |     CFDDNS_HOST_ID=homelab-node-1
167 |     CFDDNS_PROXY=enabled
168 |     CFDDNS_TTL=180
169 |     CFDDNS_RUN_EVERY=10m
170 |     CFDDNS_STATE_FILE=/tmp/cfddns-eth0.state

209 | 210 | 211 | ## Installation 212 | 213 | ### AUR 214 | 215 | There are two packages in AUR ( 216 | [1](https://aur.archlinux.org/packages/cloudflare-dynamic-dns/), 217 | [2](https://aur.archlinux.org/packages/cloudflare-dynamic-dns-bin/) 218 | ), that can be used on Arch-based distros: 219 | 220 | ```shell 221 | yay -S cloudflare-dynamic-dns 222 | # OR 223 | yay -S cloudflare-dynamic-dns-bin 224 | ``` 225 | 226 | ### Docker 227 | 228 | See the 229 | [container registry page](https://github.com/Zebradil/cloudflare-dynamic-dns/pkgs/container/cloudflare-dynamic-dns) 230 | for details. 231 | 232 | ```shell 233 | docker pull ghcr.io/zebradil/cloudflare-dynamic-dns:latest 234 | ``` 235 | 236 | ### DEB, RPM, APK 237 | 238 | See the [latest release page](https://github.com/Zebradil/cloudflare-dynamic-dns/releases/latest) for the full list of 239 | packages. 240 | 241 | ### Nix 242 | 243 | The package is available in the Nixpkgs repository under the name 244 | [`cloudflare-dynamic-dns`](https://search.nixos.org/packages?channel=unstable&show=cloudflare-dynamic-dns&from=0&size=50&sort=relevance&type=packages&query=cloudflare-dynamic-dns). 245 | 246 | ```shell 247 | nix-shell -p cloudflare-dynamic-dns 248 | ``` 249 | 250 | > [!NOTE] 251 | > The version in Nixpkgs is falling behind the latest release. If you need the latest version, use the flake. 252 | > 253 | > ```shell 254 | > nix shell 'github:Zebradil/cloudflare-dynamic-dns/main#cloudflare-dynamic-dns' 255 | > ``` 256 | 257 | ### Manual 258 | 259 | Download the archive for your OS from the [releases page](https://github.com/Zebradil/cloudflare-dynamic-dns/releases). 260 | 261 | Or get the source code and build the binary: 262 | 263 | ```shell 264 | git clone https://github.com/Zebradil/cloudflare-dynamic-dns.git 265 | # OR 266 | curl -sL https://github.com/Zebradil/cloudflare-dynamic-dns/archive/refs/heads/master.tar.gz | tar xz 267 | 268 | cd cloudflare-dynamic-dns-master 269 | go build -o cloudflare-dynamic-dns main.go 270 | ``` 271 | 272 | Now you can run `cloudflare-dynamic-dns` manually (see [Usage](#usage) section). 273 | 274 | If you want to do some automation with systemd, `cloudflare-dynamic-dns` has to be installed system-wide 275 | (it _is_ possible to run systemd timer and service without root privileges, but I do not provide ready-to-use configuration for this yet): 276 | 277 | ```shell 278 | sudo install -Dm755 cloudflare-dynamic-dns -t /usr/bin 279 | sudo install -Dm644 systemd/* -t /usr/lib/systemd/system 280 | sudo install -m700 -d /etc/cloudflare-dynamic-dns/config.d 281 | ``` 282 | 283 | ## Usage examples 284 | 285 | ### Run manually 286 | 287 | 0. Follow the steps from the [Installation](#installation) section. 288 | 1. Run `./cloudflare-dynamic-dns --domains 'example.com,*.example.com' --iface eth0 --token cloudflare-api-token` 289 | - NOTE: instead of compiling `cloudflare-dynamic-dns` binary, it can be replaced with `go run main.go` in the command above. 290 | 291 | Instead of specifying command line arguments, it is possible to create `~/.cloudflare-dynamic-dns.yaml` with the following structure: 292 | 293 | ```yaml 294 | iface: eth0 295 | token: cloudflare-api-token 296 | domains: 297 | - example.com 298 | - '*.example.com' 299 | ``` 300 | 301 | And then run `./cloudflare-dynamic-dns` (or `go run main.go`) without arguments. 302 | Or put the configuration in any place and specify it with `--config` flag: 303 | 304 | ```shell 305 | ./cloudflare-dynamic-dns --config /any/place/config.yaml 306 | ``` 307 | 308 | #### Run in a Docker container 309 | 310 | For the binary, the usage is the same as for the manual run. 311 | For the Docker container, we need to mount the configuration file into the container and provide access to the network stack of the host machine: 312 | 313 | ```shell 314 | docker run --rm \ 315 | --volume="/any/place/config.yaml:/config.yaml" \ 316 | --network=host \ 317 | ghcr.io/zebradil/cloudflare-dynamic-dns:latest \ 318 | --config=/config.yaml 319 | ``` 320 | 321 | To run the program in daemon mode, add `--run-every` flag (and `--detach` if you want to run it in the background): 322 | 323 | ```shell 324 | docker run --rm \ 325 | --volume="/any/place/config.yaml:/config.yaml" \ 326 | --network=host \ 327 | --detach \ 328 | ghcr.io/zebradil/cloudflare-dynamic-dns:latest \ 329 | --config=/config.yaml \ 330 | --run-every=5m 331 | ``` 332 | 333 | ### Systemd service and timer 334 | 335 | It is possible to run `cloudflare-dynamic-dns` periodically via systemd. 336 | This requires privileged access to the system. 337 | Make sure that required systemd files are installed (see [Installation](#installation) section for details). 338 | 339 | ```shell 340 | # 1.

Only global unicast addresses (GUA) and unique local addresses (ULA) are 43 | considered. 44 | 2. GUA addresses are preferred over ULA addresses. 45 | 3. Unique EUI-64 addresses are preferred over randomly generated addresses. 46 | 4. If priority subnets are specified, addresses from the subnet with the 47 | highest priority are selected. The priority is determined by the order of 48 | subnets specified on the command line or in the config file. 49 | 50 | IPv4 address selection 51 | -------------------------------------------------------------------------------- 52 | 53 | When multiple IPv4 addresses are found on the interface or received from the 54 | external command (e.g., when using --ipcmd), the following rules are used to 55 | select the one to use: 56 | 1. All IPv4 addresses are considered. 57 | 2. Public addresses are preferred over Shared Address Space (RFC 6598) 58 | addresses. 59 | 3. Shared Address Space addresses are preferred over private addresses. 60 | 4. Private addresses are preferred over loopback addresses. 61 | 5. If priority subnets are specified, addresses from the subnet with the 62 | highest priority are selected. The priority is determined by the order of 63 | subnets specified on the command line or in the config file. 64 | 65 | Non-public addresses are logged as warnings but are still used. They can be 66 | useful in private networks or when using a VPN. 67 | 68 | NOTE: Cloudflare doesn't allow proxying of records with non-public addresses. 69 | 70 | Daemon mode 71 | -------------------------------------------------------------------------------- 72 | 73 | By default, the program runs once and exits. This mode of operation can be 74 | changed by setting the --run-every flag to a duration greater than 1m. In this 75 | case, the program will run repeatedly, waiting the duration between runs. It 76 | will stop if killed or if failed. 77 | 78 | State file 79 | -------------------------------------------------------------------------------- 80 | 81 | Setting --state-file makes the program to retain the previously used address 82 | between runs to avoid unnecessary calls to the Cloudflare API. 83 | 84 | The value is used as the state file path. When used with an empty value, the 85 | state file is named after the interface name and the domains, and is stored 86 | either in the current directory or in the directory specified by the 87 | STATE_DIRECTORY environment variable. 88 | 89 | The STATE_DIRECTORY environment variable is automatically set by systemd. It 90 | can be set manually when running the program outside of systemd. 91 | 92 | Multihost mode (EXPERIMENTAL) 93 | -------------------------------------------------------------------------------- 94 | 95 | In this mode, it is possible to assign multiple addresses to a single or 96 | multiple domains. For correct operation, this mode must be enabled on all hosts 97 | participating in the same domain and different host-ids must be specified for 98 | each host (see --host-id option). This mode is enabled by passing --multihost 99 | flag. 100 | 101 | In the multihost mode, the program will manage only the DNS records that have 102 | the same host-id as the one specified on the command line or in the config file. 103 | If an existing record has no host-id but has the same address as the target one, 104 | it will be claimed by this host via setting the corresponding host-id. Any other 105 | records will be ignored. This allows multiple hosts to share the same domain 106 | without interfering with each other. The host-id is stored in the Cloudflare DNS 107 | comments field (see https://developers.cloudflare.com/dns/manage-dns-records/reference/record-attributes/). 108 | 109 | Persistent configuration 110 | -------------------------------------------------------------------------------- 111 | 112 | The program can be configured using a config file. The default location is 113 | $HOME/.cloudflare-dynamic-dns.yaml. The config file location can be overridden 114 | using the --config flag. The config file format is YAML. The following options 115 | are supported (with example values): 116 | 117 | # === required fields 118 | # either iface or ipcmd must be specified 119 | iface: eth0 120 | # ipcmd: curl -fsSL https://api6.ipify.org 121 | token: cloudflare-api-token 122 | domains: 123 | - example.com 124 | - "*.example.com" 125 | # === optional fields 126 | # --- mode 127 | stack: ipv6 128 | # --- UI 129 | log-level: info 130 | # --- logic 131 | priority-subnets: 132 | - 2001:db8::/32 133 | - 2001:db8:1::/48 134 | multihost: true 135 | host-id: homelab-node-1 136 | # --- DNS record details 137 | proxy: enabled 138 | ttl: 180 139 | # --- daemon mode 140 | run-every: 10m 141 | state-file: /tmp/cfddns-eth0.state 142 | 143 | Environment variables 144 | -------------------------------------------------------------------------------- 145 | 146 | The configuration options can be specified as environment variables.
