Caddy Docker¶
Caddy 2 is a powerful, enterprise-ready, open source web server with automatic HTTPS written in Go.
Docker¶
$ echo "hello world" > index.html
$ docker run -d -p 80:80 \
-v $PWD/index.html:/usr/share/caddy/index.html \
-v caddy_data:/data \
caddy
$ curl http://localhost/
hello world
To override the default Caddyfile, you can mount a new one at /etc/caddy/Caddyfile:
$ docker run -d -p 80:80 \
-v $PWD/Caddyfile:/etc/caddy/Caddyfile \
-v caddy_data:/data \
caddy
Automatic TLS with the Caddy image¶
docker run -d -p 80:80 -p 443:443 -p 443:443/udp \
-v /site:/srv \
-v caddy_data:/data \
-v caddy_config:/config \
caddy caddy file-server --domain example.com
Graceful reloads¶
caddy_container_id=$(docker ps | grep caddy | awk '{print $1;}')
docker exec -w /etc/caddy $caddy_container_id caddy reload
