Custom abiosoft/caddy-docker image

Caddy

Custom docker image based on abiosoft/caddy.

The only differences are that this image is built with the following plugins:

• git
• filebrowser
• cors
• realip
• expires
• cache
• geoip
• nobots
• reauth
• webdav
• cloudflare
• googlecloud
• login

and telemetry stats are disabled.

I originally had issues with telemetry timing out causing Caddy to hang on startup so they are disabled.

Using Cloudflare DNS plugin

When you deploy your docker container you must pass the following env variables in order for the cloudflare plugin to work.

-e CLOUDFLARE_EMAIL=<[e-mail]>
-e CLOUDFLARE_API_KEY=<your-cf-api-key>

domain.tld {
    tls {
        dns cloudflare
    }
}

Your Cloudflare API key can be found under your Cloudflare account.

Using GoogleCloud DNS plugin

Pass the following during deploy:

-e GCE_PROJECT=<project_name>
-e GCE_DOMAIN=<domain.tld>
-e GOOGLE_APPLICATION_CREDENTIALS=<credentials> 
~OR~ 
-e GCE_SERVICE_ACCOUNT_FILE=<credentials-json-file>

domain.tld {
    tls {
        dns googlecloud
    }
}

Example docker-compose file.
