Node.js cli tool for updating [TransIP](https://www.transip.nl/) DNS entries using the TransIP REST API. Supports:

- Installing globally as cli tool
- Running as Docker container
- Listing all DNS entries for one or more domains.
- Updating the content of one or more DNS entries of one or more domains.
- Running a service which updates content of one or more DNS entries of one or more domains to the public IPv4 and / or IPv6 address of the current machine (DDNS).

# Creating your private key

1. Go to https://www.transip.nl/cp/account/api/
2. Create a new Key Pair. Note: the 'Whitelisted IP' must not be checked if you want to use `ddns-service`.
3. Save the private key in a file, e.g. `private-key.pem`.

## Installation

### NPM

1. Install Node.js 18.x or higher ([Windows](https://nodejs.org/en/download/current/) | [Linux](https://github.com/nodesource/distributions#debinstall) | [OSx](https://nodejs.org/en/download/current/)).
2. `npm i -g transip-dns-cli`

### Docker Run

Note: the Docker image is a multiarch image. So it will also work on Raspberry Pi's.

```
sudo docker run \
 --name transip-dns-cli \
 --rm \
  marklagendijk/transip-dns-cli list-dns \
 --username="myusername" \
 --privateKey="$(<private-key.pem)" \
 --domainName="example.nl"
```

### Docker Compose

`docker-compose.yml`:

```yaml
version: "3"
services:
  transip-dns-cli:
    image: marklagendijk/transip-dns-cli
    restart: unless-stopped
    volumes:
      - ./private-key.pem:/home/node/app/private-key.pem
    command: ddns-service --username="myusername" --privateKeyFile="private-key.pem" --domainName="example.nl" --type="A"
```

## CLI Documentation

### Glossary

- `domainName`: The domain you have registered at TransIP.
- `DNS entry`: Every domain has DNS configuration. This configuration consists of multiple DNS entries.
- `name`: The name of a DNS entry. E.g. `@`, `*`, `www` or `mail`.
- `type`: The type of DNS entry. Possbible types are `A`, `AAAA`, `CNAME`, `MX`, `NS`, `TXT`, `SRV`, `SSHFP` and `TLSA`.
- `expire`: The expiration time of a DNS entry in seconds. E.g `3600` (1 hour).
- `content`: The content of a DNS entry. IPv4 address for type `A` entries, IPv6 address for type `AAAA` entries, etc.

### Environment variables

All args can also be specified as environment variables, with the `TRANSIP_` prefix:

```bash
TRANSIP_USERNAME=myusername
TRANSIP_PRIVATE_KEY=$(<private-key.pem)
TRANSIP_PRIVATE_KEY_FILE=private-key.pem
TRANSIP_DOMAIN_NAME=example.nl
TRANSIP_NAME=@
TRANSIP_TYPE=A
TRANSIP_CONTENT=127.0.0.1
TRANSIP_DRY_RUN=true
