Caddy reverse proxy

a year ago by WubbyGeth to c/selfhosted

I 'm trying to setup a caddy reverse proxy within Docker and I am following the guide in this YouTube video

https://www.youtube.com/watch?v=qj45uHP7Jmo but when I the run docker compose up -d command I get this error:

failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: error mounting "/home/Joe/container/caddy/Caddyfile" to rootfs at "/etc/caddy/Caddyfile": create mountpoint for /etc/caddy/Caddyfile mount: cannot create subdirectories in "/var/lib/docker/overlay2/49e15938cd9c418a331b963f6fbbd3bba726b28748113ee8d028f6adf034b525/merged/etc/caddy/Caddyfile": not a directory: unknown: Are you trying to mount a directory onto a file (or vice-versa)? Check if the specified host path exists and is the expected type

I am a bit perplexed on what I am doing wrong so any advice would be appreciated!

Can you share your compose file? You should be able to paste into code blocks in a comment or your original post. It's likely you've yamld something wrong.

I do but I am wondering if the syntax in my caddyfile is wrong.

I did get past my initial error thanks to this group but I cannot get to my portainer via host name still.

Caddy can format caddyfiles;

caddy fmt --overwrite /home/Joe/container/caddy/Caddyfile
caddy validate --config /home/Joe/container/caddy/Caddyfile --adapter caddyfile

You can format it automatically

Here is my YAMLD YAML haha

The error suggests that you're trying to mount a file (Caddyfile) onto a directory or vice versa. Let's debug this step by step.

Steps to Fix:

Check if the path exists and is correct Run:
```
ls -ld /home/Joe/container/caddy/Caddyfile
```
- If it’s a directory, it should be a file instead.
- If it doesn’t exist, create an empty one:
```
touch /home/Joe/container/caddy/Caddyfile
```

Ensure correct permissions

chmod 644 /home/Joe/container/caddy/Caddyfile

Check YAML Formatting
Your docker-compose.yml seems to have incorrect indentation and improper quotes around version. Here's a fixed version:

version: "3.3"

networks:
  caddy:

services:
  portainer:
    image: portainer/portainer-ce:latest
    container_name: portainer2
    restart: unless-stopped
    security_opt:
      - no-new-privileges:true
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - /home/Joe/containers/portainer/portainer-data:/data
    networks:
      - caddy
    ports:
      - 9000:9000

  caddy:
    image: caddy:latest
    restart: unless-stopped
    container_name: caddy
    ports:
      - 80:80
      - 443:443
    volumes:
      - /home/Joe/container/caddy/Caddyfile:/etc/caddy/Caddyfile
      - /home/Joe/container/caddy/site:/srv
      - /home/Joe/container/caddy/caddy_data:/data
      - /home/Joe/container/caddy/caddy_config:/config
    networks:
      - caddy

Restart Docker and Try Again

docker compose down
docker compose up -d

If the error persists, check docker logs caddy for additional hints.

I have always had trouble whenever I tried mounting files, and it seems that you're getting the same error, "not a directory".

Stick to mounting directories and you should be fine

/home/Joe/container/caddy:/etc/caddy

I was successful in installing and using caddy directly on my host instead of podman (docker).

Edit: someone doesn't like that I succeeded at it ...

Thank you everyone for your help!

I elected to start from scratch and use nginx and have come across another issue that I am hoping someone can shed some light on.

I've purchased a domain.
configured CloudFlare to use as my DNS.
set up a CNAME for my two test containers.
set up my SSL cert in nginx
forwarded the proper ports on my router for my test containers.
Configured two hosts. AudioBookShelf and Portainer

I can get to my Audiobookshelf perfectly from the web but when I try to reach my portainer it just re-directs to my audiobookshelf container.

When I disable audiobookshelf and attempt access my portainer I now get error code 521 website down. I am not sure what I misconfigured.

Ik this sounds like a stackoverflow kind of thing to say but why u using caddy not nginx?

Edit: I've uploaded my nginx config if you would like to take a look https://github.com/muntedcrocodile/nginxconf

Caddy is growing in popularity and finding its ways into more and more tutorials. Traefik and Caddy seem to be found in more reverse proxy tutorials/docs than NPM anymore. Forget about SWAG these days.

Because caddy has built in, and default enabled, SSL of all sites using letsencrypt, something nginx doesn't have from what I can see.

Nginx does not have default SSL but the example I've uploaded has its quite a simple setup and gives you far greater control and modularity.
