## Description

A nestjs service that grabs your ip from https://ifconfig.co and updates a record in route 53 to point to that.  
Effectively aws dynamic dns as a docker.

## Project setup

```bash
$ npm install
```

### Env vars

You can use a `.env` file for local dev

```
# The keys from the IAM user below
AWS_ACCESS_KEY_ID=
AWS_SECRET_ACCESS_KEY=
PORT=3000
CRON=0 0 */4 * * *
# The record name is your hostname, i.e. subdomain.domain.co.uk
RECORD_NAME=
# From hosted zone details
HOSTED_ZONE_ID=
```

### AWS

Create a new IAM user and attach a policy to change the records in your zone:

```json
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": ["route53:ChangeResourceRecordSets"],
      "Resource": "arn:aws:route53:::hostedzone/HOSTED_ZONE_ID"
    }
  ]
}
```

Create a new access key and use the credentials in the env vars to allow access.

## Compile and run the project

```bash
# development
$ npm run start

# watch mode
$ npm run start:dev

# production mode
$ npm run start:prod
```
