(default "env")
-checkInterval int

## Dockerize it
### Create an image
Change the startup options like Domain, Prometheus listen port, or scheduled intervals, edit the appropriate settings in the `Dockerfile` before building.
Current defaults are :
`CMD ["/app/main", "-auth=env" ,"-checkInterval=99" ,"-domain=erter.org" ,"-subDomain=dev" ,"-promExpPort=9101"]`
From the repository folder:
`docker image build -t godaddyupdater:1.0 .`
### Run the container
Create a file for the environment variables, for example `env.env` like this:
```text
godaddykey=supersecretkey
godaddysecret=supersecretsecret
```
Then run the docker container:
`docker run -it --env-file env.env -p 9101:9101 godaddyupdater:1.0`
To make it start in daemon mode:
`docker run -d --env-file env.env -p 9101:9101 godaddyupdater:1.0`
