# Mythic Beasts DNS manager
A simple management agent for controlling your DNS entries on the Mythic Beasts platform using a (version-controllable) YAML file.
This client uses the DNSv2 API (https://www.mythic-beasts.com/support/api/dnsv2) for which you'll need to create a key (https://www.mythic-beasts.com/customer/api-users).
## Configuration
1. Create an API key via https://www.mythic-beasts.com/customer/api-users
2. Create a YAML file
```yaml
defaults:
ttl:
example.com: 3600
api: https://api.mythic-beasts.com/dns/v2/zones
api_host: api.mythic-beasts.com:443
realm: Mythic Beasts DNS API
auth:
key: mykey
secret: mysecret
zones:
example.com:
```
3. Under `zones -> example.com`, prepare your DNS entries using the schema:
```yaml
zones:
example.com:
name1:
TYPE: value
name2:
TYPE:
- value1
- value2
name3.subdomain:
TYPE: value
```
Currently only a single zone is supported.
## Supported types
The client currently supports all of the Record Types implemented by the Mythic Beasts API except `SSHFP` and `TLSA`.
## Value syntax
The value for simple record types is the plain value as expected (eg. `A: 10.54.22.9` or `AAAA: 2a01:332::2`).
The value for complex types, such as `MX` is as per the standard zone file (eg. `MX: 10 mta.example.com`) At some point this will become parametrised.
## The Root object (`@`)
To refer to the base/root domain, use the `"@"` key:
```yaml
zones:
example.com:
"@":
A: 10.54.22.9
AAAA: 2a01:332::2
MX:
- 10 mta1.example.com
- 10 mta2.example.com
```
## Aliases virtual type
There is a virtual record type `aliases` which is a list of names to CNAME to this record.
For example:
```yaml
zones:
example.com:
"@":
A: 10.54.22.9
aliases:
- www
- ftp
```
# Running
Invoke the docker container with the input yaml file:
```bash
docker run --rm -ti -v "${PWD}:/a" -w /a fooflington/mythic-dns mafoo.org.uk.yml
```
## Dry run
Pass the environment variable `DRY_RUN` to prevent any changes:
```bash
docker run --rm -ti -v "${PWD}:/a" -w /a -e DRY_RUN=1 fooflington/mythic-dns mafoo.org.uk.yml
```
