Caddy server install issues on Unraid

[Hans_van_der_Drift]

1. Caddy version (caddy version):

Cannot run, latest Alpine version

2. How I run Caddy:

Unraid Docker

a. System environment:

Unraid 6.9.2 Docker

b. Command:

N/A

c. Service/unit/compose file:

d. My complete Caddyfile or JSON config:

localhost

respond "Hello"

3. The problem I’m having:

On install I get this error:

4. Error messages and/or full log output:

docker: Error response from daemon: OCI runtime create failed: container_linux.go:367: starting container process caused: process_linux.go:495: container init caused: rootfs_linux.go:60: mounting “/mnt/user/Docker/conf/caddyv2/Caddyfile” to rootfs at “/var/lib/docker/btrfs/subvolumes/f89f46a3e1e4fe6b6836c88b80184334ca8ff63670dc5b63c3b0e35be87d072e/etc/caddy/Caddyfile” caused: 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.

The command failed.

5. What I already tried:

Adding a Caddyfile to

/etc/caddy/Caddyfile

6. Links to relevant resources:

Migrating CaddyV2 to Unraid Docker CaddyV2

So using unraid and the docker container are required to reproduce the error? That’s a lot to ask, so if you can simplify it that will speed things up. I won’t have time to go through all those steps – nor do I want to start a trial on some service – so if you can reproduce the error without unraid + docker, that would be helpful. (Basically, you’re on your own unless it can become easier to replicate.)

Caddy v2 docker in unraid

In unraid all of my dockers install to /mnt/user/appdata/ but I couldn’t find the files for the caddy docker. In the documentation for caddy I saw mention of /etc/caddy/caddyfile for the location of the file. I browsed out to that location but it didn’t exist. So under /etc/ I created the caddy folder then copied over my existing caddyfile. Then I just ran the caddy command to point to my caddyfile. It’s been working great since. I’m just not sure if that file will ever get over written so I hav…

If anyone has a working version of Caddy on Unraid would you please be able to share your contain config from the below please?

@Hans_van_der_Drift

/mnt/user/Docker/conf/caddyv2/Caddyfile

Have you actually created a file at this path in your filesystem?

The error is saying it wasn’t able to create the mount, because the file type is “unknown”.

[Hans_van_der_Drift]

Yes I have. The links in the above seems to have the same issue. But I am unable to recreate their solution.

and the contents of the file

[francislavoie]

Uh, looks like you made a directory named Caddyfile and then put a Caddyfile inside of that. Don’t do that! Remove the directory, and just create file called Caddyfile there.

[Hans_van_der_Drift]

Ok… That got it installed and it try to run. But my config (absolute beginner) must be wrong.

What is the absolute bare bones Caddyfile I could test?

run: adapting config using caddyfile: /etc/caddy/Caddyfile:3: unrecognized directive: resond
Did you mean to define a second site? If so, you must use curly braces around each site to separate their configurations.

Did you mean to define a second site? If so, you must use curly braces around each site to separate their configurations.

My mistake… I misspelt “respond”

[Hans_van_der_Drift]

Not sure if I should open another question but I’ll see if you may know how to achieve my final goal.

I have Bitwarden as my only open port on my router. All my other services are accessible via tailscale.

Bitwarden requires a https connection to work I am trying to use the tailscale/caddy integration so when I point to the tailscale https site it takes me to a ssl connection to local Bitwarden.

Thanks
