Alpine Linux is a Linux distribution built around musl libc and BusyBox. The image is only 5 MB in size and has access to a package repository that is much more complete than other BusyBox based images. This makes Alpine Linux a great image base for utilities and even production applications. Read more about Alpine Linux here and you can see how their mantra fits in right at home with Container images.
Caddy, sometimes clarified as the Caddy web server, is an open source, HTTP/2-enabled web server written in Go. It uses the Go standard library for its HTTP functionality. One of Caddy's most notable features is enabling HTTPS by default.
- Minimal size only, minimal layers
- Memory usage is minimal on a simple install.
- Auto git clone from repo with

$ docker run -d --name examplecaddy -p 2015:2015 yobasystems/alpine-caddyPoint your browser to http://host-ip:2015.
:[<version>-]php variant of this image bundles PHP-FPM. e.g. :php, :0.11.0-php
$ docker run -d --name examplecaddy -p 2015:2015 yobasystems/alpine-caddy:phpPoint your browser to http://host-ip:2015 and you will see a php info page.
Replace /path/to/php/src with your php sources directory.
$ docker run -d --name examplecaddy -v /path/to/php/src:/srv -p 2015:2015 yobasystems/alpine-caddy:phpPoint your browser to http://host-ip:2015.
Your Caddyfile must include the line startup php-fpm. For Caddy to be PID 1 in the container, php-fpm could not be started.
Caddy can serve sites from git repository using git middleware.
Replace github.com/team/repo with your repository.
$ printf "0.0.0.0\ngit github.com/team/repo" > Caddyfile$ docker run -d --name examplecaddy -v $(pwd)/Caddyfile:/etc/Caddyfile -p 2015:2015 yobasystems/alpine-caddyPoint your browser to http://host-ip:2015.
The image contains a default Caddyfile.
0.0.0.0
browse

startup php-fpm # php variant only
Note the last 2 lines are only present in the php variant.
Caddyfile: /etc/Caddyfile
Sites root: /srv
Replace /path/to/Caddyfile and /path/to/sites/root accordingly.
$ docker run -d --name examplecaddy -v /path/to/sites/root:/srv -v path/to/Caddyfile:/etc/Caddyfile -p 2015:2015 yobasystems/alpine-caddyNote that this does not work on local environments, the domain also has to resolve to the server requesting the certificate.
Use a valid domain and add email to your Caddyfile to avoid prompt at runtime.
Replace example.co.uk with your domain and user@example.co.uk with your email.
example.co.uk
tls user@example.co.uk
You can change the the ports if ports 80 and 443 are not available on host. e.g. 81:80, 444:443
$ docker run -d --name examplecaddy -v $(pwd)/Caddyfile:/etc/Caddyfile -p 80:80 -p 443:443 yobasystems/alpine-caddyOptional but advised. Save certificates on host machine to prevent regeneration every time container starts. Let's Encrypts RATE LIMITS explain the number of times you can regenerate certificates.
