INWX apply
Ensure DNS resource record entries from a JSON (exporting) file are applied through INWX API.
I wanted a text based file that:
- contains/exports all my DNS resource records for all my domains
- can be version controlled with git (or any VCS)
- works with variables for repeating/similar entries
- can be applied against INWX API to ensure all these entries exists (no more, no less)
The result is this tool that takes a JSON (exporting) file as input and ensures that exactly these entries are set at inwx name servers for you.
Install (npm)
npm install -g inwx-applyDocker
Build image yourself
docker build -t inwx-apply .Run self build image
docker run \
--rm \
-v /path/to/credentials.json:/data/credentials.json:ro \
-v /path/to/inwxDnsEntries.js:/data/inwxDnsEntries.js:ro \
inwx-applyRun pre-build image from docker hub
I've created a shell script for myself
#!/bin/sh
IMAGE_NAME=pabra/inwx-apply
IMAGE_TAG=latest
if [ "$1" = "pull" ] || [ "$1" = "--pull" ]; then
docker pull "${IMAGE_NAME}:${IMAGE_TAG}"
exit $?

docker run \
--rm \
-v "${CREDENTIALS_FILE}:/data/${CREDENTIALS_FILE_BASENAME}:ro" \
-v "${ENTRIES_FILE}:/data/${ENTRIES_FILE_BASENAME}:ro" \

"$@"Usage
inwx-apply will look in your current work directory for a file named inwxDnsEntries.js
and import it. It also runs by default in "dry-run" mode. This means it will
just show you what it would do.
If you do not want to check in your INWX credentials to your VCS, put them in a JSON file that is ignored by your VCS and import it into your DNS entries file.
Create your git ignored credential file (eg: inwx_credentials.gitignore.json):
{
"username": "my_inwx_username",
"password": "my_inwx_password",
"sharedSecret": null
}Create a js file that will import your credentials and export DNS entries as
JSON (eg: inwxDnsEntries.js)
const credentials = require('./inwx_credentials.gitignore.json');
const ttl = 3600;
const ipV4 = {

const nameServerSet = nameServers.map(name => ({

name: '*',
content: name,
}));
const soaContent = `${nameServers[0]} [email protected]`;
const soaRecord = {
