We are running caddy in a Kubernetes environment. The latest docker hub caddy update (1.0.2) has caused a panic, and our deployment never finishes. Caddy version 1.0.1 does not have this issue. This issue affects abiosoft/caddy from Docker Hub.

The error message we get is:

panic: runtime error: slice bounds out of range

With the following Caddyfile:

:80
tls off
root /var/empty
fastcgi / localhost:9000 php {
    root /var/www/public
}

Can confirm, we have the same issue. Caddyfile:

our.domain:80 {
}

our.domain:443 {
  tls self_signed

  proxy /api http://server:5000 {
    transparent
  }
}

internal.net:443 {
  tls server.crt server.key

  proxy /api http://server:5000 {
    transparent
  }
}

Looking into it. Kindly stick to 1.0.1 for now.

Looks related to this caddyserver/caddy#2706

Awesome thanks very much

Fixed upstream. Docker hub should have 1.0.3 in few hours when the builds are done.
