Caddy v2 cannot serve HTTPS

[rpisharody (Rahul)]

1. Caddy version (caddy version):

v2.1.1 h1:X9k1+ehZPYYRSqBvf/ocUgdLSRIuiNiMo7CvyGUQKeA=

2. How I run Caddy:

a. System environment:

Running in Docker.

b. Command:

Nothing fancy. A simple docker-compose up

c. Service/unit/compose file:

Here is my complete docker-compose.yml

version: '3'
services:
    caddy:
        image: caddy
        cap_add:
            - CAP_NET_BIND_SERVICE
        ports:
            - 80:80
            - 443:443
        volumes:
            - ./Caddyfile:/etc/Caddyfile
            - ./config:/config
            - ./data:/data

d. My complete Caddyfile or JSON config:

Here is my complete Caddyfile

mydomain.com
tls myemail@mydomain.com

3. The problem I’m having:

The log says that the “server is listening only on the HTTP port, so no dynamic HTTPS will be applied to this server”

4. Error messages and/or full log output:

5. What I already tried:

The same Caddyfile works well in a Caddy v1 based container. Going through the docs, this is supposed to work; but for the life of me, cannot figure out where I’m going wrong

You didn’t use the correct location for the Caddyfile volume. By default, the config loaded is at /etc/caddy/Caddyfile. The logs you’re seeing are from the default Caddyfile which is shipped with the container, which only listens on :80.

Also, that config is definitely incomplete, You’ll need to add more directives for Caddy to do anything useful. In Caddy v1, a file server was always enabled by default, but in v2, it must be explicitly enabled with the file_server directive. You’ll want to set root as well to go along with this so Caddy knows where to read files from.

Welcome to the forum! Thank you for filling out the template.

[rpisharody (Rahul)]

Thank You for not being too harsh. This is a classic RTFM moment for me.
I only needed to change the Docker mount to /etc/caddy/Caddyfile for it to work !

No worries! Not the most obvious mistake - I had to read your post over a couple times to notice.

Hope you have fun with Caddy!
