# DNSControl Action
|
|
|
|
|
|
|
|
Deploy your DNS configuration using [GitHub Actions](https://github.com/actions)
|
|
using [DNSControl](https://github.com/StackExchange/dnscontrol/).
|
|
|
|
## Usage
|
|
|
|
These are the three relevant sub commands to use with this action.
|
|
|
|
### check
|
|
|
|
Run the action with the 'check' argument in order to check and validate the `dnsconfig.js`
|
|
file. This action does not communicate with the DNS providers, hence does not require
|
|
any secrets to be set.
|
|
|
|
```yaml
|
|
name: Check
|
|
|
|
on: pull_request
|
|
|
|
jobs:
|
|
check:
|
|
runs-on: ubuntu-latest
|
|
steps:
|
|
- uses: actions/checkout@v2
|
|
|
|
- name: DNSControl check
|
|
uses: koenrh/dnscontrol-action@v3
|
|
with:
|
|
args: check
|
|
dnscontrol_config_file: '.' # optional path to dnsconfig.js.
|
|
dnscontrol_creds_file: '.' # optional path to creds.json.
|
|
```
|
|
|
|
### preview
|
|
|
|
Run the action with the 'preview' argument to check what changes need to be made.
|
|
It prints out what DNS records are expected to be created, modified or deleted.
|
|
This action requires the secrets for the specified DNS providers.
|
|
|
|
```yaml
|
|
name: Preview
|
|
|
|
on: pull_request
|
|
|
|
jobs:
|
|
preview:
|
|
runs-on: ubuntu-latest
|
|
steps:
|
|
- uses: actions/checkout@v2
|
|
|
|
- name: DNSControl preview
|
|
uses: koenrh/dnscontrol-action@v3
|
|
env:
|
|
CLOUDFLARE_API_TOKEN: ${{ secrets.CLOUDFLARE_API_TOKEN }}
|
|
with:
|
|
args: preview
|
|
dnscontrol_config_file: '.' # optional path to dnsconfig.js.
|
|
dnscontrol_creds_file: '.' # optional path to creds.json.
|
|
```
|
|
|
|
This is the action you probably want to run for each branch so that proposed changes
|
|
could be verified before an authorized person merges these changes into the default
|
|
branch.
|
|
|
|
#### Pull request comment
|
|
|
|
Optionally, you could configure your GitHub Action so that the output of the 'preview'
|
|
command is published as a comment to the pull request for the branch containing the
|
|
changes. This saves you several clicks through the menus to get to the output logs
|
|
for the preview job.
|
|
|
|
```

|
|
|
|
Provided that your GitHub Action job for 'preview' is named `preview`, you could
|
|
use the following snippet to enable pull request comments using Unsplash's [comment-on-pr](https://github.com/unsplash/comment-on-pr)
|
|
GitHub Action.
|
|
|
|
```yaml
|
|
- name: Preview pull request comment
|
|
uses: unsplash/comment-on-pr@v1.2.0
|
|
env:
|
|
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
|
|
with:
|
|
msg: |
|
|
```
|
|
${{ steps.preview.outputs.output }}
|
|
```
|
|
check_for_duplicate_msg: true
|
|
```
|
|
|
|
### push
|
|
|
|
Run the action with the 'push' arugment to publish the changes to the specified
|
|
DNS providers.
|
|
|
|
Running the action with the 'push' argument will publish the changes with the
|
|
specified DNS providers. The example workflow depicted below contains a filtering
|
|
pattern so that it only runs on the default branch.
|
|
|
|
```yaml
|
|
name: Push
|
|
|
|
on:
|
|
push:
|
|
branches:
|
|
- main
|
|
|
|
jobs:
|
|
push:
|
|
runs-on: ubuntu-latest
|
|
steps:
|
|
- uses: actions/checkout@v2
|
|
|
|
- name: DNSControl push
|
|
uses: koenrh/dnscontrol-action@v3
|
|
env:
|
|
CLOUDFLARE_API_TOKEN: ${{ secrets.CLOUDFLARE_API_TOKEN }}
|
|
with:
|
|
args: push
|
|
dnscontrol_config_file: '.' # optional path to dnsconfig.js.
|
|
dnscontrol_creds_file: '.' # optional path to creds.json.
|
|
```
|
|
|
|
## Credentials
|
|
|
|
Depending on the DNS providers that are used, this action requires credentials to
|
|
be set. These secrets can be configured through a file named `creds.json`. You
|
|
should **not** add secrets as plaintext to this file, but use GitHub
|
|
Actions [encrypted secrets](https://help.github.com/en/actions/configuring-and-managing-workflows/creating-and-storing-encrypted-secrets)
|
|
instead. These encrypted secrets are exposed at runtime as environment variables.
|
|
See the DNSControl [Service Providers](https://stackexchange.github.io/dnscontrol/provider-list)
|
|
documentation for details.
|
|
|
|
To follow the Cloudflare example, add an encrypted secret named `CLOUDFLARE_API_TOKEN`
|
|
and then define the `creds.json` file as follows.
|
|
|
|
```json
|
|
{
|
|
"cloudflare":{
|
|
"apitoken": "$CLOUDFLARE_API_TOKEN"
|
|
}
|
|
}
|
|
```
