# rust-cloudflare-dynamic-public-ip

Update public ip in cloudflare's DNS records automatically. You never know when your ISP is pushing updates to your router and cycle your public IP, breaking DNS records, this is my solution.

## Build and test

```

cargo build

cargo test

```

## Run

Create a `.env` file with the following secrets:

```env

CLOUDFLARE_TOKEN=xxx

CLOUDFLARE_ZONE_ID=b9bf66d603b6864d47a45ed8ebf36c8f

```

`CLOUDFLARE_ZONE_ID` can be a comma seperated list for multiple domains.

```bash

# display help

cargo run -- --help

# get the current ip

cargo run -- current

# see the affected DNS records

cargo run -- check

# monitor changes and update cloudflare DNS record

cargo run -- monitor

```

```

docker run --rm -it --env-file .env ghcr.io/apollo-roboto/rust-cloudflare-dynamic-public-ip:latest
