dockercaddy

Why does this simple Dockerfile fail for Caddy container

localhost {
        root * /testDir
        file_server
        reverse_proxy /api/* localhost:3000
}
// And dockerfile
FROM caddy:2.7.6-alpine

EXPOSE 80

EXPOSE 443

COPY Caddyfile /etc/caddy/Caddyfile

COPY testDir /testDir

CMD ["caddy", "run"]

Checked 10 times and yes the Caddyfile is in the container in the path and yes, testDir is also there.

And of course, I build it with:

docker build -t testcaddy .

and run it with:

docker run -p 80:80 -p 443:443 -d testcaddy

And nothing happens when I type localhost in browser I get:

The site can't be reached.

Solution

  • You have to give caddy a config file to use:

    CMD ["caddy", "run", "--config", "/etc/caddy/Caddyfile"]

    or load it using HTTP: https://caddyserver.com/docs/getting-started
